77-460: A phonograph record (also known as a gramophone record , especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on
154-452: A /12 if the prongs have rectangular cross-section of width a along the direction of motion. Tuning forks have traditionally been used to tune musical instruments , though electronic tuners have largely replaced them. Forks can be driven electrically by placing electronic oscillator -driven electromagnets close to the prongs. A number of keyboard musical instruments use principles similar to tuning forks. The most popular of these
231-448: A Times music critic stated: ... the time has come for serious musical criticism to take account of performances of great music reproduced by means of the records. To claim that the records have succeeded in exact and complete reproduction of all details of symphonic or operatic performances ... would be extravagant ... [but] the article of today is so far in advance of the old machines as hardly to admit classification under
308-400: A de luxe price. Later, Decca Records introduced vinyl Deccalite 78s, while other record companies used various vinyl formulations trademarked as Metrolite, Merco Plastic, and Sav-o-flex, but these were mainly used to produce "unbreakable" children's records and special thin vinyl DJ pressings for shipment to radio stations. The playing time of a phonograph record is directly proportional to
385-463: A digital signal represents the original time-varying quantity as a sampled sequence of quantized values. Digital sampling imposes some bandwidth and dynamic range constraints on the representation and adds quantization error . The term analog signal usually refers to electrical signals; however, mechanical , pneumatic , hydraulic , and other systems may also convey or be considered analog signals. An analog signal uses some property of
462-477: A phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side. For about half a century, the discs were commonly made from shellac and these records typically ran at a rotational speed of 78 rpm , giving it the nickname " 78s " ("seventy-eights"). After the 1940s, "vinyl" records made from polyvinyl chloride (PVC) became standard replacing
539-506: A 10-inch 78 in 1922 for Victor . Longer musical pieces were released as a set of records. In 1903 His Master's Voice in England made the first complete recording of an opera, Verdi 's Ernani , on 40 single-sided discs. In 1940, Commodore released Eddie Condon and his Band's recording of " A Good Man Is Hard to Find " in four parts, issued on both sides of two 12-inch 78s. The limited duration of recordings persisted from their advent until
616-416: A 12-inch conductive vinyl disc. Analog signal An analog signal ( American English ) or analogue signal ( British and Commonwealth English ) is any continuous-time signal representing some other quantity, i.e., analogous to another quantity. For example, in an analog audio signal , the instantaneous signal voltage varies continuously with the pressure of the sound waves . In contrast,
693-654: A 360- hertz steel tuning fork as its timekeeper, powered by electromagnets attached to a battery-powered transistor oscillator circuit. The fork provided greater accuracy than conventional balance wheel watches. The humming sound of the tuning fork was audible when the watch was held to the ear. Alternatives to the common A=440 standard include philosophical or scientific pitch with standard pitch of C=512. According to Rayleigh , physicists and acoustic instrument makers used this pitch. The tuning fork John Shore gave to George Frideric Handel produces C=512. Tuning forks, usually C512, are used by medical practitioners to assess
770-585: A basic, inexpensive turntable called the Duo Jr., which was designed to be connected to their radio receivers. According to Edward Wallerstein (the general manager of the RCA Victor Division), this device was "instrumental in revitalizing the industry". The production of shellac records continued throughout the 78 rpm era, which lasted until 1948 in industrialized nations. During the Second World War,
847-415: A broader and smoother frequency response, which produced a dramatically fuller, clearer and more natural-sounding recording. Soft or distant sounds that were previously impossible to record could now be captured. Volume was now limited only by the groove spacing on the record and the amplification of the playback device. Victor and Columbia licensed the new electrical system from Western Electric and recorded

#1733086319940924-549: A competing vinyl format, the 7-inch (175 mm) 45 rpm disc, with a much larger center hole. For a two-year period from 1948 to 1950, record companies and consumers faced uncertainty over which of these formats would ultimately prevail in what was known as the "War of the Speeds" (see also Format war ). In 1949 Capitol and Decca adopted the new LP format and RCA Victor gave in and issued its first LP in January 1950. The 45 rpm size
1001-463: A frequency of 32,768 Hz in the ultrasonic range (above the range of human hearing). It is made to vibrate by small oscillating voltages applied by an electronic oscillator circuit to metal electrodes plated on the surface of the crystal. Quartz is piezoelectric , so the voltage causes the tines to bend rapidly back and forth. The Accutron , an electromechanical watch developed by Max Hetzel and manufactured by Bulova beginning in 1960, used
1078-421: A governor and says that spring drives had replaced hand drives. It notes that: The speed regulator was furnished with an indicator that showed the speed when the machine was running so that the records, on reproduction, could be revolved at exactly the same speed...The literature does not disclose why 78 rpm was chosen for the phonograph industry, apparently this just happened to be the speed created by one of
1155-449: A patient's hearing. This is most commonly done with two exams called the Weber test and Rinne test , respectively. Lower-pitched ones, usually at C128, are also used to check vibration sense as part of the examination of the peripheral nervous system. Orthopedic surgeons have explored using a tuning fork (lowest frequency C=128) to assess injuries where bone fracture is suspected. They hold
1232-635: A phonograph record that would hold at least 20 minutes per side. Research began in 1939, was suspended during World War II, and then resumed in 1945. Columbia Records unveiled the LP at a press conference in the Waldorf-Astoria on 21 June 1948, in two formats: 10 inches (25 centimetres) in diameter, matching that of 78 rpm singles, and 12 inches (30 centimetres) in diameter. Unwilling to accept and license Columbia's system, in February 1949, RCA Victor released
1309-465: A real fracture while wondering if a response means a sprain. A systematic review published in 2014 in BMJ Open suggests that this technique is not reliable or accurate enough for clinical use. Tuning forks also play a role in several alternative therapy practices, such as sonopuncture and polarity therapy . A radar gun that measures the speed of cars or a ball in sports is usually calibrated with
1386-420: A relatively low pressure (thus low acoustic impedance). The pitch of a tuning fork can also be heard directly through bone conduction , by pressing the tuning fork against the bone just behind the ear, or even by holding the stem of the fork in one's teeth, conveniently leaving both hands free. Bone conduction using a tuning fork is specifically used in the Weber and Rinne tests for hearing in order to bypass
1463-581: A small solid circle that fit onto the bottom of the spindle (meaning only one 45 could be played at a time) or a larger adapter that fit over the entire spindle, permitting a stack of 45s to be played. RCA Victor 45s were also adapted to the smaller spindle of an LP player with a plastic snap-in insert known as a " 45 rpm adapter ". These inserts were commissioned by RCA president David Sarnoff and were invented by Thomas Hutchison. Capacitance Electronic Discs were videodiscs invented by RCA, based on mechanically tracked ultra-microgrooves (9541 grooves/inch) on
1540-426: A special release for Record Store Day 2011, Capitol re-released The Beach Boys single " Good Vibrations " in the form of a 10-inch 78-rpm record (b/w "Heroes and Villains"). More recently, The Reverend Peyton's Big Damn Band has released their tribute to blues guitarist Charley Patton Peyton on Patton on both 12-inch LP and 10-inch 78s. CBS Laboratories had long been at work for Columbia Records to develop
1617-436: A standard temperature. The standard temperature is now 20 °C (68 °F), but 15 °C (59 °F) is an older standard. The pitch of other instruments is also subject to variation with temperature change. The frequency of a tuning fork depends on its dimensions and what it is made from: where The ratio I / A in the equation above can be rewritten as r /4 if the prongs are cylindrical with radius r , and
SECTION 20
#17330863199401694-455: A three- or four-speed player (78, 45, 33 + 1 ⁄ 3 , and sometimes 16 + 2 ⁄ 3 rpm); with changer, a tall spindle that would hold several records and automatically drop a new record on top of the previous one when it had finished playing, a combination cartridge with both 78 and microgroove styli and a way to flip between the two; and some kind of adapter for playing the 45s with their larger center hole. The adapter could be
1771-485: A time, with four items per EP, or in a boxed set with three EPs or twelve items. The large center hole on 45s allows easier handling by jukebox mechanisms. EPs were generally discontinued by the late 1950s in the U.S. as three- and four-speed record players replaced the individual 45 players. One indication of the decline of the 45 rpm EP is that the last Columbia Records reissue of Frank Sinatra songs on 45 rpm EP records, called Frank Sinatra (Columbia B-2641)
1848-438: A track from his self-titled debut album (with "The Beehive State" on the flipside). Reprise did not proceed further with the series due to a lack of sales for the single, and a lack of general interest in the concept. In 1978, guitarist and vocalist Leon Redbone released a promotional 78-rpm single featuring two songs ("Alabama Jubilee" and "Please Don't Talk About Me When I'm Gone") from his Champagne Charlie album. In
1925-445: A tuning fork. Instead of the frequency, these forks are labeled with the calibration speed and radar band (e.g., X-band or K-band) they are calibrated for. Doubled and H-type tuning forks are used for tactical-grade Vibrating Structure Gyroscopes and various types of microelectromechanical systems . Tuning fork forms the sensing part of vibrating point level sensors . The tuning fork is kept vibrating at its resonant frequency by
2002-431: A variety known as extended play (EP), which achieved up to 10–15 minutes play at the expense of attenuating (and possibly compressing) the sound to reduce the width required by the groove. EP discs were cheaper to produce and were used in cases where unit sales were likely to be more limited or to reissue LP albums on the smaller format for those people who had only 45 rpm players. LP albums could be purchased one EP at
2079-400: A variety of sizes. As early as 1894, Emile Berliner 's United States Gramophone Company was selling single-sided 7-inch discs with an advertised standard speed of "about 70 rpm". One standard audio recording handbook describes speed regulators, or governors , as being part of a wave of improvement introduced rapidly after 1897. A picture of a hand-cranked 1898 Berliner Gramophone shows
2156-511: Is an acoustic resonator in the form of a two-pronged fork with the prongs ( tines ) formed from a U-shaped bar of elastic metal (usually steel ). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out. A tuning fork's pitch depends on the length and mass of the two prongs. They are traditional sources of standard pitch for tuning musical instruments. The tuning fork
2233-413: Is because its principal mode of vibration is symmetric, with the two prongs always moving in opposite directions, so that at the base where the two prongs meet there is a node (point of no vibratory motion) which can therefore be handled without removing energy from the oscillation (damping). However, there is still a tiny motion induced in the handle in its longitudinal direction (thus at right angles to
2310-522: Is converted to an analog signal by a transducer . For example, sound striking the diaphragm of a microphone induces corresponding fluctuations in the current produced by a coil in an electromagnetic microphone or the voltage produced by a condenser microphone . The voltage or the current is said to be an analog of the sound. An analog signal is subject to electronic noise and distortion introduced by communication channels , recording and signal processing operations, which can progressively degrade
2387-616: Is irreversible as there is no reliable method to distinguish the noise from the signal. Converting an analog signal to digital form introduces a low-level quantization noise into the signal due to finite resolution of digital systems. Once in digital form, the signal can be transmitted, stored, and processed without introducing additional noise or distortion using error detection and correction . Noise accumulation in analog systems can be minimized by electromagnetic shielding , balanced lines , low-noise amplifiers and high-quality electrical components. Tuning fork A tuning fork

2464-428: Is reduced, just as a loudspeaker requires a baffle in order to radiate efficiently. Commercial tuning forks are tuned to the correct pitch at the factory, and the pitch and frequency in hertz is stamped on them. They can be retuned by filing material off the prongs. Filing the ends of the prongs raises the pitch, while filing the inside of the base of the prongs lowers it. Currently, the most common tuning fork sounds
2541-401: Is that the frequency of the first overtone is about 5 / 2 = 25 / 4 = 6 + 1 ⁄ 4 times the fundamental (about 2 + 1 ⁄ 2 octaves above it). By comparison, the first overtone of a vibrating string or metal bar is one octave above (twice) the fundamental, so when the string is plucked or the bar is struck, its vibrations tend to mix
2618-469: Is the Rhodes piano , in which hammers hit metal tines that vibrate in the magnetic field of a pickup , creating a signal that drives electric amplification. The earlier, un-amplified dulcitone , which used tuning forks directly, suffered from low volume. The quartz crystal that serves as the timekeeping element in modern quartz clocks and watches is in the form of a tiny tuning fork. It usually vibrates at
2695-634: The Victor Talking Machine Company in Camden, New Jersey, whose products would come to dominate the market for several decades. Berliner's Montreal factory, which became the Canadian branch of RCA Victor , still exists. There is a dedicated museum in Montreal for Berliner ( Musée des ondes Emile Berliner ). Early disc recordings were produced in a variety of speeds ranging from 60 to 130 rpm, and
2772-541: The Waldorf-Astoria Hotel was front-page news in The New York Times , which reported: The audience broke into applause ... John Philip Sousa [said]: '[Gentlemen], that is a band. This is the first time I have ever heard music with any soul to it produced by a mechanical talking machine' ... The new instrument is a feat of mathematics and physics. It is not the result of innumerable experiments, but
2849-449: The middle ear . If just held in open air, the sound of a tuning fork is very faint due to the acoustic impedance mismatch between the steel and air. Moreover, since the feeble sound waves emanating from each prong are 180° out of phase , those two opposite waves interfere , largely cancelling each other. Thus when a solid sheet is slid in between the prongs of a vibrating fork, the apparent volume actually increases , as this cancellation
2926-532: The rotational speed in revolutions per minute (rpm) at which they are played ( 8 + 1 ⁄ 3 , 16 + 2 ⁄ 3 , 33 + 1 ⁄ 3 , 45, 78), and their time capacity, determined by their diameter and speed (LP [long play], 12-inch disc, 33 + 1 ⁄ 3 rpm; EP [extended play], 12-inch disc or 7-inch disc, 33 + 1 ⁄ 3 or 45 rpm; Single, 7-inch or 10-inch disc, 45 or 78 rpm); their reproductive quality, or level of fidelity (high-fidelity, orthophonic, full-range, etc.); and
3003-454: The signal-to-noise ratio (SNR). As the signal is transmitted, copied, or processed, the unavoidable noise introduced in the signal path will accumulate as a generation loss , progressively and irreversibly degrading the SNR, until in extreme cases, the signal can be overwhelmed. Noise can show up as hiss and intermodulation distortion in audio signals, or snow in video signals . Generation loss
3080-607: The "B" side. In the 1990s Rhino Records issued a series of boxed sets of 78-rpm reissues of early rock and roll hits, intended for owners of vintage jukeboxes . The records were made of vinyl, however, and some of the earlier vintage 78-rpm jukeboxes and record players (the ones that were pre-war) were designed with heavy tone arms to play the hard slate-impregnated shellac records of their time. These vinyl Rhino 78s were softer and would be destroyed by old juke boxes and old record players, but play well on newer 78-capable turntables with modern lightweight tone arms and jewel needles. As
3157-591: The 1880s. Emile Berliner improved the quality of recordings while his manufacturing associate Eldridge R. Johnson , who owned a machine shop in Camden, New Jersey , eventually improved the mechanism of the gramophone with a spring motor and a speed regulating governor, resulting in a sound quality equal to Edison's cylinders. Abandoning Berliner's "Gramophone" trademark for legal reasons in the United States, Johnson's and Berliner's separate companies reorganized in 1901 to form

3234-498: The 1990s, records continue to be manufactured and sold on a smaller scale, and during the 1990s and early 2000s were commonly used by disc jockeys (DJs), especially in dance music genres. They were also listened to by a growing number of audiophiles . The phonograph record has made a niche resurgence in the early 21st century, growing increasingly popular throughout the 2010s and 2020s. Phonograph records are generally described by their diameter in inches (12-inch, 10-inch, 7-inch),
3311-401: The 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media , in the form of the compact disc , had gained a larger market share, and the record left the mainstream in 1991. Since
3388-508: The United States Armed Forces produced thousands of 12-inch vinyl 78 rpm V-Discs for use by the troops overseas. After the war, the use of vinyl became more practical as new record players with lightweight crystal pickups and precision-ground styli made of sapphire or an exotic osmium alloy proliferated. In late 1945, RCA Victor began offering "De Luxe" transparent red vinylite pressings of some Red Seal classical 78s, at
3465-770: The available groove length divided by the turntable speed. Total groove length in turn depends on how closely the grooves are spaced, in addition to the record diameter. At the beginning of the 20th century, the early discs played for two minutes, the same as cylinder records. The 12-inch disc, introduced by Victor in 1903, increased the playing time to three and a half minutes. Because the standard 10-inch 78 rpm record could hold about three minutes of sound per side, most popular recordings were limited to that duration. For example, when King Oliver 's Creole Jazz Band, including Louis Armstrong on his first recordings, recorded 13 sides at Gennett Records in Richmond, Indiana, in 1923, one side
3542-455: The corner, looking all sad." During the first half of the 1920s, engineers at Western Electric , as well as independent inventors such as Orlando Marsh , developed technology for capturing sound with a microphone , amplifying it with vacuum tubes (known as valves in the UK), and then using the amplified signal to drive an electromechanical recording head. Western Electric's innovations resulted in
3619-520: The earliest jazz and military band recordings. The loudest instruments such as the drums and trumpets were positioned the farthest away from the collecting horn. Lillian Hardin Armstrong , a member of King Oliver's Creole Jazz Band , which recorded at Gennett Records in 1923, remembered that at first Oliver and his young second trumpet, Louis Armstrong , stood next to each other and Oliver's horn could not be heard. "They put Louis about fifteen feet over in
3696-590: The early machines and, for no other reason continued to be used. In 1912, the Gramophone Company set 78 rpm as their recording standard, based on the average of recordings they had been releasing at the time, and started selling players whose governors had a nominal speed of 78 rpm. By 1925, 78 rpm was becoming standardized across the industry. However, the exact speed differed between places with alternating current electricity supply at 60 hertz (cycles per second, Hz) and those at 50 Hz. Where
3773-486: The end of the vibrating fork on the skin above the suspected fracture, progressively closer to the suspected fracture. If there is a fracture, the periosteum of the bone vibrates and fires nociceptors (pain receptors), causing a local sharp pain. This can indicate a fracture, which the practitioner refers for medical X-ray. The sharp pain of a local sprain can give a false positive. Established practice, however, requires an X-ray regardless, because it's better than missing
3850-429: The first 45 rpm single, 7 inches in diameter with a large center hole. The 45 rpm player included a changing mechanism that allowed multiple disks to be stacked, much as a conventional changer handled 78s. Also like 78s, the short playing time of a single 45 rpm side meant that long works, such as symphonies and operas, had to be released on multiple 45s instead of a single LP, but RCA Victor claimed that
3927-475: The first electrical discs during the spring of 1925. The first electrically recorded Victor Red Seal record was Chopin 's "Impromptus" and Schubert 's "Litanei" performed by pianist Alfred Cortot at Victor's studios in Camden, New Jersey . A 1926 Wanamaker's ad in The New York Times offers records "by the latest Victor process of electrical recording". It was recognized as a breakthrough; in 1930,
SECTION 50
#17330863199404004-441: The formerly standard "78s" over the next decade. The late 1950s saw the introduction of stereophonic sound on commercial discs. The phonautograph was invented by 1857 by Frenchman Édouard-Léon Scott de Martinville. It could not, however, play back recorded sound, as Scott intended for people to read back the tracings, which he called phonautograms. Prior to this, tuning forks had been used in this way to create direct tracings of
4081-403: The fundamental and overtone frequencies. When the tuning fork is struck, little of the energy goes into the overtone modes; they also die out correspondingly faster, leaving a pure sine wave at the fundamental frequency. It is easier to tune other instruments with this pure tone. Another reason for using the fork shape is that it can then be held at the base without damping the oscillation. That
4158-463: The introduction of the LP record in 1948. In popular music, the time limit of 3 + 1 ⁄ 2 minutes on a 10-inch 78 rpm record meant that singers seldom recorded long pieces. One exception is Frank Sinatra 's recording of Rodgers and Hammerstein 's " Soliloquy ", from Carousel , made on 28 May 1946. Because it ran 7m 57s, longer than both sides of a standard 78 rpm 10-inch record, it
4235-480: The late 19th century, at first competing with earlier cylinder records. Price, ease of use and storage made the disc record dominant by the 1910s. The standard format of disc records became known to later generations as "78s" after their playback speed in revolutions per minute, although that speed only became standardized in the late 1920s. In the late 1940s new formats pressed in vinyl, the 45 rpm single and 33 rpm long playing "LP", were introduced, gradually overtaking
4312-547: The mains supply was 60 Hz, the actual speed was 78.26 rpm: that of a 60 Hz stroboscope illuminating 92-bar calibration markings. Where it was 50 Hz, it was 77.92 rpm: that of a 50 Hz stroboscope illuminating 77-bar calibration markings. At least one attempt to lengthen playing time was made in the early 1920s. World Records produced records that played at a constant linear velocity , controlled by Noel Pemberton Billing 's patented add-on speed governor. Early recordings were made entirely acoustically,
4389-492: The medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage , current , or frequency of the signal may be varied to represent the information. Any information may be conveyed by an analog signal; such a signal may be a measured response to changes in a physical variable, such as sound , light , temperature , position, or pressure . The physical variable
4466-433: The new high-speed changer rendered side breaks so brief as to be inconsequential. Early 45 rpm records were made from either vinyl or polystyrene . They had a playing time of eight minutes. At first the two systems were marketed in competition, in what was called " The War of the Speeds ". The older 78 rpm format continued to be mass-produced alongside the newer formats using new materials in decreasing numbers until
4543-427: The note of A = 440 Hz , the standard concert pitch that many orchestras use. That A is the pitch of the violin's second-highest string, the highest string of the viola, and an octave above the highest string of the cello. Orchestras between 1750 and 1820 mostly used A = 423.5 Hz, though there were many forks and many slightly different pitches. Standard tuning forks are available that vibrate at all
4620-529: The number of audio channels ( mono , stereo , quad , etc.). The phrase broken record refers to a malfunction when the needle skips/jumps back to the previous groove and plays the same section over and over again indefinitely. The various names have included phonograph record (American English), gramophone record (British English), record, vinyl, LP (originally a trademark of Columbia Records ), black disc, album, and more informally platter, wax, or liquorice pizza. Manufacture of disc records began in
4697-456: The old 78s and remain so to this day; they have since been produced in various sizes and speeds, most commonly 7-inch discs played at 45 rpm (typically for singles , also called 45s ("forty-fives")), and 12-inch discs played at 33⅓ rpm (known as an LP , "long-playing records", typically for full-length albums ) – the latter being the most prevalent format today. The phonograph record was the primary medium used for music reproduction throughout

#17330863199404774-430: The oscillation of the prongs) which can be made audible using any sort of sound board . Thus by pressing the tuning fork's base against a sound board such as a wooden box, table top, or bridge of a musical instrument, this small motion, but which is at a high acoustic pressure (thus a very high acoustic impedance ), is partly converted into audible sound in air which involves a much greater motion ( particle velocity ) at
4851-487: The pitches within the central octave of the piano, and also other pitches. Tuning fork pitch varies slightly with temperature, due mainly to a slight decrease in the modulus of elasticity of steel with increasing temperature. A change in frequency of 48 parts per million per °F (86 ppm per °C) is typical for a steel tuning fork. The frequency decreases (becomes flat ) with increasing temperature. Tuning forks are manufactured to have their correct pitch at
4928-483: The same name. Electrical recording and reproduction have combined to retain vitality and color in recitals by proxy. The Orthophonic Victrola had an interior folded exponential horn, a sophisticated design informed by impedance-matching and transmission-line theory, and designed to provide a relatively flat frequency response. Victor's first public demonstration of the Orthophonic Victrola on 6 October 1925, at
5005-523: The same vein of Tin Pan Alley revivals, R. Crumb & His Cheap Suit Serenaders issued a number of 78-rpm singles on their Blue Goose record label. The most familiar of these releases is probably R. Crumb & His Cheap Suit Serenaders' Party Record (1980, issued as a "Red Goose" record on a 12-inch single), with the double-entendre " My Girl's Pussy " on the "A" side and the X-rated "Christopher Columbus" on
5082-404: The second session, on 30 April, the two 12-inch recordings were longer: "Embraceable You" was 4m 05s; "Serenade to a Shylock", 4m 32s. Another way to overcome the time limitation was to issue a selection extending to both sides of a single record. Vaudeville stars Gallagher and Shean recorded "Mr. Gallagher and Mr. Shean", written by themselves or, allegedly, by Bryan Foy, as two sides of
5159-470: The sound was collected by a horn and piped to a diaphragm , which vibrated the cutting stylus. Sensitivity and frequency range were poor, and frequency response was irregular, giving acoustic recordings an instantly recognizable tonal quality. A singer almost had to put their face in the recording horn. A way of reducing resonance was to wrap the recording horn with tape. Even drums, if planned and placed properly, could be effectively recorded and heard on even
5236-679: The summer of 1958 in the U.S., and in a few countries, such as the Philippines and India (both countries issued recordings by the Beatles on 78s), into the late 1960s. For example, Columbia Records ' last reissue of Frank Sinatra songs on 78 rpm records was an album called Young at Heart , issued in November 1954. Columbia and RCA Victor each pursued their R&D secretly. The commercial rivalry between RCA Victor and Columbia Records led to RCA Victor's introduction of what it had intended to be
5313-423: The vibrations of sound-producing objects, as by English physicist Thomas Young in 1807. In 1877, Thomas Edison invented the first phonograph , which etched sound recordings onto phonograph cylinders . Unlike the phonautograph, Edison's phonograph could both record and reproduce sound, via two separate needles, one for each function. The first commercially sold disc records were created by Emile Berliner in
5390-434: Was 2:09 and four sides were 2:52–2:59. In January 1938, Milt Gabler started recording for Commodore Records , and to allow for longer continuous performances, he recorded some 12-inch discs. Eddie Condon explained: "Gabler realized that a jam session needs room for development." The first two 12-inch recordings did not take advantage of their capability: "Carnegie Drag" was 3m 15s; "Carnegie Jump", 2m 41s. But at
5467-622: Was gaining in popularity, too, and Columbia issued its first 45s in February 1951. By 1954, 200 million 45s had been sold. Eventually the 12-inch (300 mm) 33 + 1 ⁄ 3 rpm LP prevailed as the dominant format for musical albums, and 10-inch LPs were no longer issued. The last Columbia Records reissue of any Frank Sinatra songs on a 10-inch LP record was an album called Hall of Fame , CL 2600, issued on 26 October 1956, containing six songs, one each by Tony Bennett , Rosemary Clooney , Johnnie Ray , Frank Sinatra , Doris Day , and Frankie Laine .

5621-529: Was issued on 7 December 1959. The Seeburg Corporation introduced the Seeburg Background Music System in 1959, using a 16 + 2 ⁄ 3 rpm 9-inch record with 2-inch center hole. Each record held 40 minutes of music per side, recorded at 420 grooves per inch. From the mid-1950s through the 1960s, in the U.S. the common home record player or "stereo" (after the introduction of stereo recording) would typically have had these features:
5698-534: Was not until the LP era that an entire album of material could be included on a single record. In 1968, when the hit movie Thoroughly Modern Millie was inspiring revivals of Jazz Age music, Reprise planned to release a series of 78-rpm singles from their artists on their label at the time, called the Reprise Speed Series. Only one disc actually saw release, Randy Newman 's "I Think It's Going to Rain Today",
5775-501: Was released on Columbia 's Masterwork label (the classical division) as two sides of a 12-inch record. In the 78 era, classical-music and spoken-word items generally were released on the longer 12-inch 78s, about 4–5 minutes per side. For example, on 10 June 1924, four months after the 12 February premier of Rhapsody in Blue , George Gershwin recorded an abridged version of the seventeen-minute work with Paul Whiteman and His Orchestra. It
5852-479: Was released on two sides of Victor 55225 and ran for 8m 59s. "Record albums" were originally booklets containing collections of multiple disc records of related material, the name being related to photograph albums or scrap albums. German record company Odeon pioneered the album in 1909 when it released the Nutcracker Suite by Tchaikovsky on four double-sided discs in a specially designed package. It

The 'phonograph tone' is eliminated by the new recording and reproducing process. Sales of records plummeted precipitously during the early years of the Great Depression of the 1930s, and the entire record industry in America nearly foundered. In 1932, RCA Victor introduced
