134-419: A SAMI file provides closed caption support for multimedia formats. Generally, a multimedia file (such as a video or a sound file) is played by a media player such as Windows Media Player . Media players that support closed captioning and SAMI format may display the contents of the included SAMI file. A SAMI file is a plain text file and therefore can be created or modified in any text editor. Its structure

268-421: A chord progression (a sequence of chords), which is the norm in small jazz and blues groups. Rehearsals of orchestras, concert bands and choirs are led by a conductor. Rock, blues and jazz bands are usually led by the bandleader. A rehearsal is a structured repetition of a song or piece by the performers until it can be sung or played correctly and, if it is a song or piece for more than one musician, until

402-408: A computer screen . In ancient times, music notation was put onto stone or clay tablets. To perform music from notation, a singer or instrumentalist requires an understanding of the rhythmic and pitch elements embodied in the symbols and the performance practice that is associated with a piece of music or genre. In genres requiring musical improvisation , the performer often plays from music where only

536-407: A music box , barrel organ , or digital audio workstation software on a computer. Music often plays a key role in social events and religious ceremony . The techniques of making music are often transmitted as part of a cultural tradition. Music is played in public and private contexts, highlighted at events such as festivals and concerts for various different types of ensembles. Music is used in

670-418: A transcription of the audio portion of a program as it occurs (either verbatim or in edited form), sometimes including descriptions of non-speech elements. Other uses have included providing a textual alternative language translation of a presentation's primary audio language that is usually burned-in (or "open") to the video and unselectable. HTML5 defines subtitles as a "transcription or translation of

804-508: A "respeaker": a trained human who repeats the running commentary (with careful enunciation and some simplification and markup ) for input to the automated text generation system. This is generally reliable, though errors are not unknown. The National Captioning Institute was created in 1979 in order to get the cooperation of the commercial television networks. The first use of regularly scheduled closed captioning on American television occurred on March 16, 1980. Sears had developed and sold

938-637: A "self-portrait, a gesture of friendship, prescription for an ideal party... [and] an environment consisting solely of what is most ardently loved". Amateur musicians can compose or perform music for their own pleasure and derive income elsewhere. Professional musicians are employed by institutions and organisations, including armed forces (in marching bands , concert bands and popular music groups), religious institutions, symphony orchestras, broadcasting or film production companies, and music schools . Professional musicians sometimes work as freelancers or session musicians , seeking contracts and engagements in

1072-433: A SAMI file. Sometimes that is achieved by using the same filename as the underlying media file. For example, when Windows Media Player (WMP) opens the sound file cheap44.wav, it checks to see if the file cheap44.smi exists in the same folder. If it does, WMP uses that file to display closed captions. Alternatively, the association can be made explicit using an entry in an Advanced Stream Redirector (ASX) file. The user opens

1206-515: A TV set itself, approximately $ 200.) Through discussions with the manufacturer it was established that the appropriate circuitry integrated into the television set would be less expensive than the stand-alone box, and Ronald May, then a Sanyo employee, provided the expert witness testimony on behalf of Sanyo and Gallaudet University in support of the passage of the bill. On January 23, 1991, the Television Decoder Circuitry Act of 1990

1340-461: A defense to scare off predators. Prehistoric music can only be theorized based on findings from paleolithic archaeology sites. The disputed Divje Babe flute , a perforated cave bear femur , is at least 40,000 years old, though there is considerable debate surrounding whether it is truly a musical instrument or an object formed by animals. The earliest objects whose designations as musical instruments are widely accepted are bone flutes from

1474-451: A fashion. The closest word to mean music in Chinese , yue , shares a character with le , meaning joy, and originally referred to all the arts before narrowing in meaning. Africa is too diverse to make firm generalizations, but the musicologist J. H. Kwabena Nketia has emphasized African music's often inseparable connection to dance and speech in general. Some African cultures, such as

1608-450: A form of sexual selection , perhaps via mating calls. Darwin's original perspective has been heavily criticized for its inconsistencies with other sexual selection methods, though many scholars in the 21st century have developed and promoted the theory. Other theories include that music arose to assist in organizing labor, improving long-distance communication, benefiting communication with the divine , assisting in community cohesion or as

1742-560: A foundation to the development of a closed caption production system. They were working with professor Alan Newell from the University of Southampton who had been developing prototypes in the late 1960s. The closed captioning system was successfully encoded and broadcast in 1973 with the cooperation of PBS station WETA . As a result of these tests, the FCC in 1976 set aside line 21 for the transmission of closed captions. PBS engineers then developed

1876-611: A further grant from the Australian government enabled the ACC to achieve and maintain financial self-sufficiency. The ACC, now known as Media Access Australia , sold its commercial captioning division to Red Bee Media in December 2005. Red Bee Media continues to provide captioning services in Australia today. In 1981, TVNZ held a telethon to raise funds for Teletext-encoding equipment used for

2010-557: A human operator (a speech-to-text reporter ) using stenotype - or stenomask -type machines, whose phonetic output is instantly translated into text by a computer and displayed on the screen. This technique was developed in the 1970s as an initiative of the BBC 's Ceefax teletext service. In collaboration with the BBC, a university student took on the research project of writing the first phonetics-to-text conversion program for this purpose. Sometimes,

2144-543: A lighter, clearer and considerably simpler texture than the Baroque music which preceded it. The main style was homophony , where a prominent melody and a subordinate chordal accompaniment part are clearly distinct. Classical instrumental melodies tended to be almost voicelike and singable. New genres were developed, and the fortepiano , the forerunner to the modern piano, replaced the Baroque era harpsichord and pipe organ as

2278-457: A mix of prepared and live content, such as news bulletins , a combination of techniques is used. For prerecorded programs, commercials, and home videos, audio is transcribed and captions are prepared, positioned, and timed in advance. For all types of NTSC programming, captions are encoded into line 21 of the vertical blanking interval  – a part of the TV picture that sits just above

2412-558: A new diversity in theatre music , including operetta , and musical comedy and other forms of musical theatre. In the 19th century, a key way new compositions became known to the public was by the sales of sheet music , which middle class amateur music lovers would perform at home, on their piano or other common instruments, such as the violin. With 20th-century music , the invention of new electric technologies such as radio broadcasting and mass market availability of gramophone records meant sound recordings heard by listeners (on

2546-514: A performer learns a song " by ear ". When the composer of a song or piece is no longer known, this music is often classified as "traditional" or as a "folk song". Different musical traditions have different attitudes towards how and where to make changes to the original source material, from quite strict, to those that demand improvisation or modification to the music. A culture's history and stories may also be passed on by ear through song. Music has many different fundamentals or elements. Depending on

2680-426: A performer. Although a musical composition often uses musical notation and has a single author, this is not always the case. A work of music can have multiple composers, which often occurs in popular music when a band collaborates to write a song, or in musical theatre, when one person writes the melodies, a second person writes the lyrics, and a third person orchestrates the songs. In some styles of music, such as

2814-997: A real-time mode such as the "roll up" style, type random letters on screen, and then revert to normal. Uncorrectable byte errors within the teletext page header will cause whole captions to be dropped. EIA-608, due to using only two characters per video frame, sends these captions ahead of time storing them in a second buffer awaiting a command to display them; Teletext sends these in real-time. The use of capitalization varies among caption providers. Most caption providers capitalize all words while others such as WGBH and non-US providers prefer to use mixed-case letters. There are two main styles of line 21 closed captioning: TVNZ Access Services and Red Bee Media for BBC and Australia example: UK IMS for ITV and Sky example: US WGBH Access Services example: US National Captioning Institute example: US CaptionMax example: US in-house real-time roll-up example: Non-US in-house real-time roll-up example: US VITAC example: Music Music

2948-438: A relationship between the origin of music and the origin of language , and there is disagreement surrounding whether music developed before, after, or simultaneously with language. A similar source of contention surrounds whether music was the intentional result of natural selection or was a byproduct spandrel of evolution. The earliest influential theory was proposed by Charles Darwin in 1871, who stated that music arose as

3082-457: A song may state the song is a "slow blues" or a "fast swing", which indicates the tempo and the genre. To read notation, a person must have an understanding of music theory , harmony and the performance practice associated with a particular song or piece's genre. Written notation varies with the style and period of music. Nowadays, notated music is produced as sheet music or, for individuals with computer scorewriter programs, as an image on

3216-521: A source of ideas for classical music. Igor Stravinsky , Arnold Schoenberg , and John Cage were influential composers in 20th-century art music. The invention of sound recording and the ability to edit music gave rise to new subgenres of classical music, including the acousmatic and Musique concrète schools of electronic composition. Sound recording was a major influence on the development of popular music genres, because it enabled recordings of songs and bands to be widely distributed. The introduction of

3350-425: A standard 625 line VHS recorder (due to the lack of field shifting support); they are available on all professional S-VHS recordings due to all fields being recorded. Recorded Teletext caption fields also suffer from a higher number of caption errors due to increased number of bits and a low signal-to-noise ratio , especially on low-bandwidth VHS. This is why Teletext captions were stored on floppy disk, separate from

3484-520: A strong, insistent back beat, and a catchy melody." The traditional rhythm section for popular music is rhythm guitar, electric bass guitar, drums. Some bands have keyboard instruments such as organ, piano, or, since the 1970s, analog synthesizers . In the 1980s, pop musicians began using digital synthesizers, such as the DX-7 synthesizer, electronic drum machines such as the TR-808 and synth bass devices (such as

3618-539: A transcript along with the program audio. In the United States, the National Captioning Institute noted that English as a foreign or second language (ESL) learners were the largest group buying decoders in the late 1980s and early 1990s before built-in decoders became a standard feature of US television sets. This suggested that the largest audience of closed captioning was people whose native language

3752-426: A variety of settings. There are often many links between amateur and professional musicians. Beginning amateur musicians take lessons with professional musicians. In community settings, advanced amateur musicians perform with professional musicians in a variety of ensembles such as community concert bands and community orchestras. A distinction is often made between music performed for a live audience and music that

3886-436: A vibrant tradition of secular song (non-religious songs). Examples of composers from this period are Léonin , Pérotin , Guillaume de Machaut , and Walther von der Vogelweide . Renaissance music ( c.  1400 to 1600) was more focused on secular themes, such as courtly love . Around 1450, the printing press was invented, which made printed sheet music much less expensive and easier to mass-produce (prior to

4020-512: Is pentatonic - diatonic , having a scale of twelve notes to an octave (5 + 7 = 12) as does European-influenced music. The medieval music era (500 to 1400), which took place during the Middle Ages , started with the introduction of monophonic (single melodic line) chanting into Catholic Church services. Musical notation was used since ancient times in Greek culture , but in

4154-513: Is a core component and an essential criterion of performances. Music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment product for the marketplace. When music was only available through sheet music scores, such as during the Classical and Romantic eras, music lovers would buy the sheet music of their favourite pieces and songs so that they could perform them at home on

4288-412: Is a genre of popular music that developed in the 1950s from rock and roll , rockabilly , blues , and country music . The sound of rock often revolves around the electric or acoustic guitar, and it uses a strong back beat laid down by a rhythm section . Along with the guitar or keyboards, saxophone and blues-style harmonica are used as soloing instruments. In its "purest form", it "has three chords,

4422-402: Is broad enough to include the creation of popular music and traditional music songs and instrumental pieces as well as spontaneously improvised works like those of free jazz performers and African percussionists such as Ewe drummers . Performance is the physical expression of music, which occurs when a song is sung or piano piece, guitar melody, symphony, drum beat or other musical part

4556-428: Is called aleatoric music , and is associated with contemporary composers active in the 20th century, such as John Cage , Morton Feldman , and Witold Lutosławski . A commonly known example of chance-based music is the sound of wind chimes jingling in a breeze. The study of composition has traditionally been dominated by examination of methods and practice of Western classical music, but the definition of composition

4690-440: Is gamelan, an ensemble of tuned percussion instruments that include metallophones , drums , gongs and spike fiddles along with bamboo suling (like a flute ). Chinese classical music , the traditional art or court music of China, has a history stretching over about 3,000 years. It has its own unique systems of musical notation, as well as musical tuning and pitch, musical instruments and styles or genres. Chinese music

4824-514: Is not the case worldwide, and languages such as modern Indonesian ( musik ) and Shona ( musakazo ) have recently adopted words to reflect this universal conception, as they did not have words that fit exactly the Western scope. Before Western contact in East Asia , neither Japan nor China had a single word that encompasses music in a broad sense, but culturally, they often regarded music in such

4958-427: Is notated relatively precisely, as in classical music, there are many decisions that a performer has to make, because notation does not specify all of the elements of music precisely. The process of deciding how to perform music that has been previously composed and notated is termed "interpretation". Different performers' interpretations of the same work of music can vary widely, in terms of the tempos that are chosen and

5092-463: Is often characterized as a highly versatile medium for expressing human creativity . Diverse activities are involved in the creation of music, and are often divided into categories of composition , improvisation , and performance . Music may be performed using a wide variety of musical instruments , including the human voice . It can also be composed, sequenced, or otherwise produced to be indirectly played mechanically or electronically, such as via

5226-469: Is one of the oldest musical traditions in the world. Sculptures from the Indus Valley civilization show dance and old musical instruments, like the seven-holed flute. Stringed instruments and drums have been recovered from Harappa and Mohenjo Daro by excavations carried out by Mortimer Wheeler . The Rigveda , an ancient Hindu text, has elements of present Indian music, with musical notation to denote

5360-417: Is performed in a studio so that it can be recorded and distributed through the music retail system or the broadcasting system. However, there are also many cases where a live performance in front of an audience is also recorded and distributed. Live concert recordings are popular in both classical music and in popular music forms such as rock, where illegally taped live concerts are prized by music lovers. In

5494-429: Is played. In classical music, a work is written in music notation by a composer and then performed once the composer is satisfied with its structure and instrumentation. However, as it gets performed, the interpretation of a song or piece can evolve and change. In classical music, instrumental performers, singers or conductors may gradually make changes to the phrasing or tempo of a piece. In popular and traditional music,

5628-573: Is referenced on screen by notation which says "Subtitles", or previously "Subtitles 888" or just "888" (the latter two are in reference to the conventional videotext channel for captions), which is why the term subtitle is also used to refer to the Ceefax -based videotext encoding that is used with PAL-compatible video. The term subtitle has been replaced with caption in a number of markets—such as Australia and New Zealand—that purchase large amounts of imported US material, with much of that video having had

5762-450: Is the arrangement of sound to create some combination of form , harmony , melody , rhythm , or otherwise expressive content . Music is generally agreed to be a cultural universal that is present in all human societies. Definitions of music vary widely in substance and approach. While scholars agree that music is defined by a small number of specific elements , there is no consensus as to what these necessary elements are. Music

5896-414: Is used in a number of different contexts. The two most common contexts can be differentiated by describing them as the "rudimentary elements of music" and the "perceptual elements of music". Pitch is an aspect of a sound that we can hear, reflecting whether one musical sound, note, or tone is "higher" or "lower" than another musical sound, note, or tone. We can talk about the highness or lowness of pitch in

6030-492: Is used rather than in EIA-608 , but the methods of preparation and the line 21 field used are similar. For home Beta and VHS videotapes, a shift down of this line 21 field must be done due to the greater number of VBI lines used in 625 line PAL countries, though only a small minority of European PAL VHS machines support this (or any) format for closed caption recording. Like all teletext fields, teletext captions can not be stored by

6164-471: Is very similar to HTML . The files may have either .smi or .sami filename extensions , although using .smi may cause a filename extension collision, since Synchronized Multimedia Integration Language (SMIL) files and Macintosh self mounting images also use this filename extension. SAMI format is similar to HTML and CSS ; in fact, SAMI implements a subset of both. SAMI does not require strict tag matching. Here's an example SAMI file. It sets

6298-757: The Old French musique of the 12th century; and the Latin mūsica . The Latin word itself derives from the Ancient Greek mousiké ( technē )— μουσική ( τέχνη )—literally meaning "(art) of the Muses". The Muses were nine deities in Ancient Greek mythology who presided over the arts and sciences . They were included in tales by the earliest Western authors, Homer and Hesiod , and eventually came to be associated with music specifically. Over time, Polyhymnia would reside over music more prominently than

6432-666: The Roman Empire , Eastern Europe, and the Byzantine Empire changed Greek music. The Seikilos epitaph is the oldest surviving example of a complete musical composition, including musical notation, from anywhere in the world. The oldest surviving work written about music theory is Harmonika Stoicheia by Aristoxenus . Asian music covers a swath of music cultures surveyed in the articles on Arabia , Central Asia , East Asia , South Asia , and Southeast Asia . Several have traditions reaching into antiquity. Indian classical music

6566-666: The Songye people of the Democratic Republic of the Congo and the Tiv people of Nigeria, have a strong and broad conception of 'music' but no corresponding word in their native languages. Other words commonly translated as 'music' often have more specific meanings in their respective cultures: the Hindi word for music, sangita , properly refers to art music , while the many Indigenous languages of

6968-529: The blues , a composer/songwriter may create, perform and record new songs or pieces without ever writing them down in music notation. A piece of music can also be composed with words, images, or computer programs that explain or notate how the singer or musician should create musical sounds. Examples range from avant-garde music that uses graphic notation , to text compositions such as Aus den sieben Tagen , to computer programs that select sounds for musical pieces. Music that makes heavy use of randomness and chance

7102-460: The chord changes and form of the song are written, requiring the performer to have a great understanding of the music's structure, harmony and the styles of a particular genre e.g., jazz or country music . In Western art music, the most common types of written notation are scores, which include all the music parts of an ensemble piece, and parts, which are the music notation for the individual performers or singers. In popular music, jazz, and blues,

7236-427: The fugue , the invention , the sonata , and the concerto . The late Baroque style was polyphonically complex and richly ornamented. Important composers from the Baroque era include Johann Sebastian Bach ( Cello suites ), George Frideric Handel ( Messiah ), Georg Philipp Telemann and Antonio Vivaldi ( The Four Seasons ). The music of the Classical period (1730 to 1820) aimed to imitate what were seen as

7370-413: The jam band scene, live, improvised jam sessions are preferred to studio recordings. Music notation typically means the written expression of music notes and rhythms on paper using symbols. When music is written down, the pitches and rhythm of the music, such as the notes of a melody , are notated. Music notation often provides instructions on how to perform the music. For example, the sheet music for

7504-423: The multitrack recording system had a major influence on rock music , because it could do more than record a band's performance. Using a multitrack system, a band and their music producer could overdub many layers of instrument tracks and vocals, creating new sounds that would not be possible in a live performance. Jazz evolved and became an important genre of music over the course of the 20th century, and during

7638-470: The recording and reproduction of music has historically included sheet music , microphones , phonographs , and tape machines , with playback of digital musics being a common use for MP3 players , CD players , and smartphones . The modern English word ' music ' came into use in the 1630s. It is derived from a long line of successive precursors: the Old English ' musike ' of the mid-13th century;

The most popular form of Indonesian music

7906-592: The syncretism of exploring different art-forms in a musical context, (such as literature), history (historical figures and legends), or nature itself. Romantic love or longing was a prevalent theme in many works composed during this period. In some cases, the formal structures from the classical period continued to be used (e.g., the sonata form used in string quartets and symphonies ), but these forms were expanded and altered. In many cases, new approaches were explored for existing genres, forms, and functions. Also, new forms were created that were deemed better suited to

8040-455: The 20th and early 21st century, as "common practice" Western art music performance became institutionalized in symphony orchestras, opera houses, and ballets, improvisation has played a smaller role, as more and more music was notated in scores and parts for musicians to play. At the same time, some 20th and 21st century art music composers have increasingly included improvisation in their creative work. In Indian classical music , improvisation

8308-549: The Americas have words for music that refer specifically to song but describe instrumental music regardless. Though the Arabic musiqi can refer to all music, it is usually used for instrumental and metric music, while khandan identifies vocal and improvised music. It is often debated to what extent the origins of music will ever be understood, and there are competing theories that aim to explain it. Many scholars highlight

8442-424: The BBC does live subtitling by having someone re-speak what is being broadcast. Live captioning is also a form of real-time text . Meanwhile, sport events on ESPN are using court reporters , using a special (steno) keyboard and individually constructed "dictionaries." In some cases, the transcript is available beforehand, and captions are simply displayed during the program after being edited. For programs that have

8576-412: The Classical period was the development of public concerts. The aristocracy still played a significant role in the sponsorship of concerts and compositions, but it was now possible for composers to survive without being permanent employees of queens or princes. The increasing popularity of classical music led to a growth in the number and types of orchestras. The expansion of orchestral concerts necessitated

8710-437: The Classical style of sonata is completely distinct. All of the main instrumental forms of the Classical era, from string quartets to symphonies and concertos, were based on the structure of the sonata. The instruments used chamber music and orchestra became more standardized. In place of the basso continuo group of the Baroque era, which consisted of harpsichord, organ or lute along with a number of bass instruments selected at

All TV programming distributors in the U.S. are required to provide closed captions for Spanish-language video programming as of January 1, 2010. A bill, H.R. 3101, the Twenty-First Century Communications and Video Accessibility Act of 2010, was passed by the United States House of Representatives in July 2010. A similar bill, S. 3304, with

8978-620: The Internet. On February 20, 2014, the FCC unanimously approved the implementation of quality standards for closed captioning, addressing accuracy, timing, completeness, and placement. This is the first time the FCC has addressed quality issues in captions. In 2015, a law was passed in Hawaii requiring two screenings a week of each movie with captions on the screen. In 2022 a law took effect in New York City requiring movie theaters to offer captions on

9112-662: The Middle Ages, notation was first introduced by the Catholic Church, so chant melodies could be written down, to facilitate the use of the same melodies for religious music across the Catholic empire. The only European Medieval repertory that has been found, in written form, from before 800 is the monophonic liturgical plainsong chant of the Catholic Church, the central tradition of which was called Gregorian chant . Alongside these traditions of sacred and church music there existed

9246-876: The Philippines are required to provide closed captions. As of 2018, the three major TV networks in the country are currently testing the closed captioning system on their transmissions. ABS-CBN added closed captions in their daily 3 O'Clock Habit in the afternoon. TV5 started implementing closed captions on their live noon and nightly news programs. GMA once broadcast news programs with closed captions but since stopped. Only select Korean drama and local or foreign movies, Biyahe ni Drew (English title Drew's Travel Adventure ) and Idol sa Kusina (English title Kitchen Idol ) are broadcast with proper closed captioning. Since 2016 all Filipino-language films, as well as some streaming services, like iWant, have included English subtitles in some showings. The law regarding this

The first programs seen with captioning were a Disney's Wonderful World presentation of the film Son of Flubber on NBC , an ABC Sunday Night Movie airing of Semi-Tough , and Masterpiece Theatre on PBS . Since 2010 the BBC provides captioning for all programming across all seven of its main broadcast channels BBC One , BBC Two , BBC Three , BBC Four , CBBC , CBeebies and BBC News . BBC iPlayer launched in 2008 as

9514-646: The US CC logo already superimposed over the start of it. In New Zealand, broadcasters superimpose an ear logo with a line through it that represents subtitles for the hard of hearing, even though they are currently referred to as captions. In the UK, modern digital television services have subtitles for the majority of programs, so it is no longer necessary to highlight which have subtitling/captioning and which do not. Remote control handsets for TVs, DVD players, and similar devices in most European markets often use "SUB" or "SUBTITLE" on

9648-568: The University of Tennessee in Knoxville, Tennessee, in December 1971. A second demonstration of closed captioning was held at Gallaudet College (now Gallaudet University ) on February 15, 1972, where ABC and the National Bureau of Standards demonstrated closed captions embedded within a normal broadcast of The Mod Squad . At the same time in the UK the BBC was demonstrating its Ceefax text based broadcast service which they were already using as

9782-478: The Western art music tradition, improvisation was an important skill during the Baroque era and during the Classical era. In the Baroque era, performers improvised ornaments, and basso continuo keyboard players improvised chord voicings based on figured bass notation. As well, the top soloists were expected to be able to improvise pieces such as preludes . In the Classical era, solo performers and singers improvised virtuoso cadenzas during concerts. However, in

9916-626: The analogue master tape. DVDs have their own system for subtitles and captions, which are digitally inserted in the data stream and decoded on playback into video. For older televisions, a set-top box or other decoder is usually required. In the US, since the passage of the Television Decoder Circuitry Act, manufacturers of most television receivers sold have been required to include closed captioning display capability. High-definition TV sets, receivers, and tuner cards are also covered, though

10050-487: The building of large public performance spaces. Symphonic music including symphonies, musical accompaniment to ballet and mixed vocal/instrumental genres, such as opera and oratorio , became more popular. The best known composers of Classicism are Carl Philipp Emanuel Bach , Christoph Willibald Gluck , Johann Christian Bach , Joseph Haydn , Wolfgang Amadeus Mozart , Ludwig van Beethoven and Franz Schubert . Beethoven and Schubert are also considered to be composers in

10184-545: The button used to control the display of subtitles and captions. Regular open-captioned broadcasts began on PBS 's The French Chef in 1972. WGBH began open captioning of the programs Zoom , ABC World News Tonight , and Once Upon a Classic shortly thereafter. Closed captioning was first demonstrated in the United States at the First National Conference on Television for the Hearing Impaired at

10318-643: The caption editing consoles that would be used to caption prerecorded programs. The BBC in the UK was the first broadcaster to include closed captions (called subtitles in the UK) in 1979 based on the Teletext framework for pre-recorded programming. Real-time captioning, a process for captioning live broadcasts, was developed by the National Captioning Institute in 1982. In real-time captioning, stenotype operators who are able to type at speeds of over 225 words per minute provide captions for live television programs, allowing

10452-408: The captions are not visible until activated by the viewer, usually via the remote control or menu option. On the other hand, the terms open , burned-in , baked on , hard-coded , or simply hard indicate that the captions are visible to all viewers as they are embedded in the video. In the United States and Canada, the terms subtitles and captions have different meanings. Subtitles assume

10586-415: The captions of live broadcasts, like news bulletins, sports events, live entertainment shows, and other live shows, fall behind by a few seconds. This delay is because the machine does not know what the person is going to say next, so after the person on the show says the sentence, the captions appear. Automatic computer speech recognition works well when trained to recognize a single voice, and so since 2003,

10720-599: The church to aristocratic courts, kings, queens and princes competed for the finest composers. Many leading composers came from the Netherlands, Belgium, and France; they are called the Franco-Flemish composers. They held important positions throughout Europe, especially in Italy. Other countries with vibrant musical activity included Germany, England, and Spain. The Baroque era of music took place from 1600 to 1750, coinciding with

10854-407: The commission's rules. These exceptions apply to new networks; programs in languages other than English or Spanish; networks having to spend over 2% of income on captioning; networks having less than US$ 3,000,000 in revenue; and certain local programs; among other exceptions. Those who are not covered by the exceptions may apply for a hardship waiver. The Telecommunications Act of 1996 expanded on

10988-462: The composer typically orchestrates his or her own compositions, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a songwriter may not use notation at all, and instead, compose the song in her mind and then play or record it from memory. In jazz and popular music, notable recordings by influential performers are given the weight that written scores play in classical music. Even when music

11122-477: The country, or even different parts of the world, even if they could not afford to travel to these locations. This helped to spread musical styles. The focus of art music in the 20th century was characterized by exploration of new rhythms, styles, and sounds. The horrors of World War I influenced many of the arts, including music, and composers began exploring darker, harsher sounds. Traditional music styles such as jazz and folk music were used by composers as

11256-566: The creation and editing of text-based broadcast services for the deaf. The service came into use in 1984 with caption creation and importing paid for as part of the public broadcasting fee until the creation of the NZ On Air taxpayer fund, which is used to provide captioning for NZ On Air content and TVNZ news shows and for conversion of EIA-608 US captions to the preferred EBU STL format for only TVNZ 1 , TV 2 and TV 3 with archived captions available to FOUR and select Sky programming. During

11390-406: The creation of music notation , such as a sheet music "score", which is then performed by the composer or by other singers or musicians. In popular music and traditional music, the act of composing, which is typically called songwriting, may involve the creation of a basic outline of the song, called the lead sheet , which sets out the melody , lyrics and chord progression . In classical music,

11524-412: The default is the closed caption. The identifier name need not be "Source"; it may be any name. The Microsoft parser is fragile. Formatting information can be added to the closed caption information, but adding format information to the source line can have unpredictable results. Defining more than one ID can have unpredictable results. The player needs to know how to associate a particular media file to

11658-409: The definition of "element" being used, these can include pitch, beat or pulse, tempo, rhythm, melody, harmony, texture, style, allocation of voices, timbre or color, dynamics, expression, articulation, form, and structure. The elements of music feature prominently in the music curriculums of Australia, the UK, and the US. All three curriculums identify pitch, dynamics, timbre, and texture as elements, but

11792-421: The dialogue when sound is available but not understood" by the viewer (for example, dialogue in a foreign language) and captions as a "transcription or translation of the dialogue, sound effects, relevant musical cues, and other relevant audio information when sound is unavailable or not clearly audible" (for example, when audio is muted or the viewer is deaf or hard of hearing). The term closed indicates that

11926-432: The discretion of the group leader (e.g., viol, cello, theorbo, serpent), Classical chamber groups used specified, standardized instruments (e.g., a string quartet would be performed by two violins, a viola and a cello). The practice of improvised chord-playing by the continuo keyboardist or lute player, a hallmark of Baroque music, underwent a gradual decline between 1750 and 1800. One of the most important changes made in

12060-491: The double-reed aulos and a plucked string instrument , the lyre , principally a special kind called a kithara . Music was an important part of education, and boys were taught music starting at age six. Greek musical literacy created significant musical development. Greek music theory included the Greek musical modes , that eventually became the basis for Western religious and classical music. Later, influences from

12194-488: The first captioned video-on-demand service from a major broadcaster with levels of captioning comparable to those provided on its broadcast channels. Until the passage of the Television Decoder Circuitry Act of 1990, television captioning was performed by a set-top box manufactured by Sanyo Electric and marketed by the National Captioning Institute (NCI). (At that time a set-top decoder cost about as much as

12328-694: The flourishing of the Baroque artistic style in Europe. The start of the Baroque era was marked by the penning of the first operas . Polyphonic contrapuntal music (music with separate, simultaneous melodic lines ) remained important during this period. German Baroque composers wrote for small ensembles including strings , brass , and woodwinds , as well as for choirs and keyboard instruments such as pipe organ , harpsichord , and clavichord . Musical complexity increased during this time. Several major musical forms were created, some of them which persisted into later periods, seeing further development. These include

12462-423: The informational Teletext non-caption content being discontinued. Closed captions were created for deaf and hard of hearing individuals to assist in comprehension. They can also be used as a tool by those learning to read, or those learning to speak a non-native language, or in environments where the audio is difficult to hear or is intentionally muted. Captions can also be used by viewers who simply wish to read

12596-650: The invention of the press, all notated music was hand-copied). The increased availability of sheet music spread musical styles quicker and across a larger area. Musicians and singers often worked for the church, courts and towns. Church choirs grew in size, and the church remained an important patron of music. By the middle of the 15th century, composers wrote richly polyphonic sacred music, in which different melody lines were interwoven simultaneously. Prominent composers from this era include Guillaume Du Fay , Giovanni Pierluigi da Palestrina , Thomas Morley , Orlando di Lasso and Josquin des Prez . As musical activity shifted from

12730-466: The key elements of the art and philosophy of Ancient Greece and Rome: the ideals of balance, proportion and disciplined expression. (Note: the music from the Classical period should not be confused with Classical music in general, a term which refers to Western art music from the 5th century to the 2000s, which includes the Classical period as one of a number of periods). Music from the Classical period has

12864-499: The late Romantic period, composers explored dramatic chromatic alterations of tonality , such as extended chords and altered chords , which created new sound "colors." The late 19th century saw a dramatic expansion in the size of the orchestra, and the Industrial Revolution helped to create better instruments, creating a more powerful sound. Public concerts became an important part of well-to-do urban society. It also saw

12998-450: The later part of the Classical era, as it began to move towards Romanticism. Romantic music ( c.  1820 to 1900) from the 19th century had many elements in common with the Romantic styles in literature and painting of the era. Romanticism was an artistic, literary, and intellectual movement was characterized by its emphasis on emotion and individualism as well as glorification of all

13132-489: The location of the notes to be played on the instrument using a diagram of the guitar or bass fingerboard. Tablature was used in the Baroque era to notate music for the lute , a stringed, fretted instrument. Many types of music, such as traditional blues and folk music were not written down in sheet music ; instead, they were originally preserved in the memory of performers, and the songs were handed down orally , from one musician or singer to another, or aurally, in which

13266-480: The main keyboard instrument (though pipe organ continued to be used in sacred music, such as Masses). Importance was given to instrumental music. It was dominated by further development of musical forms initially defined in the Baroque period: the sonata , the concerto, and the symphony . Other main kinds were the trio , string quartet , serenade and divertimento . The sonata was the most important and developed form. Although Baroque composers also wrote sonatas,

13400-427: The meter and mode of chanting. Indian classical music (marga) is monophonic , and based on a single melody line or raga rhythmically organized through talas . The poem Cilappatikaram provides information about how new scales can be formed by modal shifting of the tonic from an existing scale. Present day Hindi music was influenced by Persian traditional music and Afghan Mughals. Carnatic music , popular in

13534-440: The modern classical concert, religious processions, classical music festivals or music competitions . Chamber music , which is music for a small ensemble with only one or a few of each type of instrument, is often seen as more intimate than large symphonic works. Musical improvisation is the creation of spontaneous music, often within (or based on) a pre-existing harmonic framework, chord progression , or riffs . Improvisers use

13668-416: The more general sense, such as the way a listener hears a piercingly high piccolo note or whistling tone as higher in pitch than a deep thump of a bass drum . We also talk about pitch in the precise sense associated with musical melodies , basslines and chords . Precise pitch can only be determined in sounds that have a frequency that is clear and stable enough to distinguish from noise. For example, it

13802-702: The new subject matter. Composers continued to develop opera and ballet music, exploring new styles and themes. In the years after 1800, the music developed by Ludwig van Beethoven and Franz Schubert introduced a more dramatic, expressive style. In Beethoven's case, short motifs , developed organically, came to replace melody as the most significant compositional unit (an example is the distinctive four note figure used in his Fifth Symphony ). Later Romantic composers such as Pyotr Ilyich Tchaikovsky , Antonín Dvořák , and Gustav Mahler used more unusual chords and more dissonance to create dramatic tension. They generated complex and often much longer musical works. During

13936-459: The notes of the chord, various scales that are associated with each chord, and chromatic ornaments and passing tones which may be neither chord tones nor from the typical scales associated with a chord. Musical improvisation can be done with or without preparation. Improvisation is a major part of some types of music, such as blues , jazz , and jazz fusion , in which instrumental performers improvise solos, melody lines, and accompaniment parts. In

14070-719: The oldest, c.  43,150–39,370 BP. The earliest material and representational evidence of Egyptian musical instruments dates to the Predynastic period , but the evidence is more securely attested in the Old Kingdom when harps , flutes and double clarinets were played. Percussion instruments, lyres , and lutes were added to orchestras by the Middle Kingdom . Cymbals frequently accompanied music and dance, much as they still do in Egypt today. Egyptian folk music , including

14204-574: The other identified elements of music are far from universally agreed upon. Below is a list of the three official versions of the "elements of music": In relation to the UK curriculum, in 2013 the term: "appropriate musical notations " was added to their list of elements and the title of the list was changed from the "elements of music" to the "inter-related dimensions of music". The inter-related dimensions of music are listed as: pitch, duration, dynamics, tempo, timbre, texture, structure, and appropriate musical notations. The phrase "the elements of music"

14338-603: The other muses. The Latin word musica was also the originator for both the Spanish música and French musique via spelling and linguistic adjustment, though other European terms were probably loanwords , including the Italian musica , German Musik , Dutch muziek , Norwegian musikk , Polish muzyka and Russian muzïka . The modern Western world usually defines music as an all-encompassing term used to describe diverse genres, styles, and traditions. This

14472-573: The parts are together from a rhythmic and tuning perspective. Many cultures have strong traditions of solo performance (in which one singer or instrumentalist performs), such as in Indian classical music, and in the Western art-music tradition. Other cultures, such as in Bali , include strong traditions of group performance. All cultures include a mixture of both, and performance may range from improvised solo playing to highly planned and organized performances such as

14606-695: The past and nature. Romantic music expanded beyond the rigid styles and forms of the Classical era into more passionate, dramatic expressive pieces and songs. Romantic composers such as Wagner and Brahms attempted to increase emotional expression and power in their music to describe deeper truths or human feelings. With symphonic tone poems , composers tried to tell stories and evoke images or landscapes using instrumental music. Some composers promoted nationalistic pride with patriotic orchestral music inspired by folk music . The emotional and expressive qualities of music came to take precedence over tradition. Romantic composers grew in idiosyncrasy, and went further in

14740-428: The performers have more freedom to make changes to the form of a song or piece. As such, in popular and traditional music styles, even when a band plays a cover song , they can make changes such as adding a guitar solo or inserting an introduction. A performance can either be planned out and rehearsed (practiced)—which is the norm in classical music, jazz big bands , and many popular music styles–or improvised over

14874-469: The piano. With the advent of the phonograph , records of popular songs, rather than sheet music became the dominant way that music lovers would enjoy their favourite songs. With the advent of home tape recorders in the 1980s and digital music in the 1990s, music lovers could make tapes or playlists of favourite songs and take them with them on a portable cassette player or MP3 player. Some music lovers create mix tapes of favourite songs, which serve as

15008-401: The playing or singing style or phrasing of the melodies. Composers and songwriters who present their own music are interpreting their songs, just as much as those who perform the music of others. The standard body of choices and techniques present at a given time and a given place is referred to as performance practice , whereas interpretation is generally used to mean the individual choices of

15142-504: The production of other media, such as in soundtracks to films, TV shows, operas, and video games. Listening to music is a common means of entertainment . The culture surrounding music extends into areas of academic study , journalism , philosophy , psychology , and therapy . The music industry includes songwriters, performers, sound engineers , producers, tour organizers, distributors of instruments, accessories, and publishers of sheet music and recordings . Technology facilitating

15276-705: The radio or record player) became the main way to learn about new songs and pieces. There was a vast increase in music listening as the radio gained popularity and phonographs were used to replay and distribute music; anyone with a radio or record player could hear operas, symphonies and big bands in their own living room. During the 19th century, the focus on sheet music had restricted access to new music to middle and upper-class people who could read music and who owned pianos and other instruments. Radios and record players allowed lower-income people, who could not afford an opera or symphony concert ticket, to hear this music. As well, people could hear music from different parts of

15410-428: The recording digitally. In the 1990s, bands in genres such as nu metal began including DJs in their bands. DJs create music by manipulating recorded music, using a DJ mixer . "Composition" is the act or practice of creating a song, an instrumental music piece, a work with both singing and instruments, or another type of music. In many cultures, including Western classical music, the act of composing also includes

15544-428: The result. When a video is truly and accurately transcribed, then the closed-captioning publication serves a useful purpose, and the content is available for search engines to index and make available to users on the Internet. Some television sets can be set to automatically turn captioning on when the volume is muted. For live programs, spoken words comprising the television program's soundtrack are transcribed by

15678-542: The same name, was passed by the United States Senate on August 5, 2010 and by the House of Representatives on September 28, 2010, and was signed by President Barack Obama on October 8, 2010. The Act requires, in part, any ATSC -decoding set-top box remote to have a button to turn the closed captioning in the output signal on or off. It also requires broadcasters to provide captioning for television programs redistributed on

15812-447: The screen for up to four showtimes per movie each week, including weekends and Friday nights. Some state and local governments (including Boston, Massachusetts ; Portland, Oregon ; Rochester, New York ; and the State of Washington ) require closed captioning to be activated on TVs in public places at all times, even if no one has requested it. As amended by RA 10905, all TV networks in

15946-488: The second half of 2012, TV3 and FOUR began providing non-Teletext DVB image-based captions on their HD service and used the same format on the satellite service, which has since caused major timing issues in relation to server load and the loss of captions from most SD DVB-S receivers, such as the ones Sky Television provides their customers. As of April 2, 2013, only the Teletext page 801 caption service will remain in use with

16080-535: The second half, rock music did the same. Jazz is an American musical artform that originated in the beginning of the 20th century, in African American communities in the Southern United States from a confluence of African and European music traditions. The style's West African pedigree is evident in its use of blue notes , improvisation , polyrhythms , syncopation , and the swung note . Rock music

16214-616: The southern states, is largely devotional; the majority of the songs are addressed to the Hindu deities. There are songs emphasizing love and other social issues. Indonesian music has been formed since the Bronze Age culture migrated to the Indonesian archipelago in the 2nd-3rd centuries BCE. Indonesian traditional music uses percussion instruments, especially kendang and gongs . Some of them developed elaborate and distinctive instruments, such as

16348-586: The standard musical notation is the lead sheet , which notates the melody, chords, lyrics (if it is a vocal piece), and structure of the music. Fake books are also used in jazz; they may consist of lead sheets or simply chord charts, which permit rhythm section members to improvise an accompaniment part to jazz songs. Scores and parts are also used in popular music and jazz, particularly in large ensembles such as jazz " big bands ." In popular music, guitarists and electric bass players often read music notated in tablature (often abbreviated as "tab"), which indicates

16482-433: The technical specifications are different (high-definition display screens, as opposed to high-definition TVs, may lack captioning). Canada has no similar law but receives the same sets as the US in most cases. During transmission, single byte errors can be replaced by a white space which can appear at the beginning of the program. More byte errors during EIA-608 transmission can affect the screen momentarily, by defaulting to

16616-474: The term closed caption has come to be used to also refer to the North American EIA-608 encoding that is used with NTSC-compatible video. The United Kingdom , Ireland , and a number of other countries do not distinguish between subtitles and captions and use subtitles as the general term. The equivalent of captioning is usually referred to as subtitles for the hard of hearing . Their presence

16750-455: The time to milliseconds. It uses CSS for formatting both the source and text lines and it supports language selection. (English and faux-French shown). Each SYNC block sets the start time for the caption. A new caption is displayed every second (1000ms). The Class= identifies the language. The ID=Source (matching the #Source in the CSS identifier definition) indicates the source/speaker line;

16884-463: The traditional Sufi dhikr rituals, are the closest contemporary music genre to ancient Egyptian music, having preserved many of its features, rhythms and instruments. The " Hurrian Hymn to Nikkal ", found on clay tablets in the ancient Syrian city of Ugarit , is the oldest surviving notated work of music, dating back to approximately 1400 BCE. Music was an important part of social and cultural life in ancient Greece , in fact it

17018-453: The viewer can hear but cannot understand the language or accent, or the speech is not entirely clear, so they transcribe only dialogue and some on-screen text. Captions aim to describe to the deaf and hard of hearing all significant audio content—spoken dialogue and non-speech information such as the identity of speakers and, occasionally, their manner of speaking—along with any significant music or sound effects using words or symbols. Also,

17152-451: The viewer to see the captions within two to three seconds of the words being spoken. Major US producers of captions are WGBH-TV , VITAC , CaptionMax and the National Captioning Institute . In the UK and Australasia , Ai-Media, Red Bee Media , itfc, and Independent Media Support are the major vendors. Improvements in speech recognition technology mean that live captioning may be fully or partially automated. BBC Sport broadcasts use

17286-494: The visible portion and is usually unseen. For ATSC ( digital television ) programming, three streams are encoded in the video: two are backward compatible line 21 captions, and the third is a set of up to 63 additional caption streams encoded in EIA-708 format. Captioning is modulated and stored differently in PAL and SECAM countries (625 lines, 50 fields per second), where teletext

17420-575: Was not English. In the United Kingdom, of 7.5 million people using TV subtitles (closed captioning), 6 million have no hearing impairment. Closed captions are also used in public environments, such as bars and restaurants, where patrons may not be able to hear over the background noise, or where multiple televisions are displaying different programs. In addition, online videos may be treated through digital processing of their audio content by various robotic algorithms (robots). Multiple chains of errors are

17554-496: Was one of the main subjects taught to children. Musical education was considered important for the development of an individual's soul. Musicians and singers played a prominent role in Greek theater , and those who received a musical education were seen as nobles and in perfect harmony (as can be read in the Republic, Plato ). Mixed gender choruses performed for entertainment, celebration, and spiritual ceremonies. Instruments included

17688-534: Was passed by Congress. This Act gave the Federal Communications Commission (FCC) power to enact rules on the implementation of closed captioning. This Act required all analog television receivers with screens of at least 13 inches or greater, either sold or manufactured, to have the ability to display closed captioning by July 1, 1993. Also, in 1990, the Americans with Disabilities Act (ADA)

17822-732: Was passed to ensure equal opportunity for persons with disabilities. The ADA prohibits discrimination against persons with disabilities in public accommodations or commercial facilities. Title III of the ADA requires that public facilities—such as hospitals, bars, shopping centers and museums (but not movie theaters)—provide access to verbal information on televisions, films and slide shows. The Federal Communications Commission requires all providers of programs to caption material which has audio in English or Spanish, with certain exceptions specified in Section 79.1(d) of

17956-484: Was proposed by Gerald Anthony Gullas Jr., a lawmaker from Cebu City, who had implemented the regulations on standardizing both official languages of the Philippines, as the people had not mastered English vocabulary. The government of Australia provided seed funding in 1981 for the establishment of the Australian Caption Centre (ACC) and the purchase of equipment. Captioning by the ACC commenced in 1982 and
