In music, just intonation or pure intonation is the tuning of musical intervals as whole number ratios (such as 3:2 or 4:3) of frequencies . An interval tuned in this way is said to be pure, and is called a just interval . Just intervals (and chords created by combining them) consist of tones from a single harmonic series of an implied fundamental . For example, in the diagram, if the notes G3 and C4 (labelled 3 and 4) are tuned as members of the harmonic series of the lowest C, their frequencies will be 3 and 4 times the fundamental frequency. The interval ratio between C4 and G3 is therefore 4:3, a just fourth .
91-435: Surname Partch is a surname. Notable people with the surname include: Harry Partch (1901–1974), American composer, music theorist, and creator of musical instruments, uncle of Virgil Partch Virgil Partch (1916–1984), American cartoonist See also [ edit ] Patch (disambiguation)#People Pertsch [REDACTED] Surname list This page lists people with
182-509: A perfect fifth created using the 3:2 ratio and a tempered fifth using some other system, such as meantone or equal temperament . 5-limit tuning encompasses ratios additionally using the number 5 and its powers, such as 5:4, a major third , and 15:8, a major seventh . The specialized term perfect third is occasionally used to distinguish the 5:4 ratio from major thirds created using other tuning methods. 7 limit and higher systems use higher prime number partials in
273-500: A Music (1947). He opens the book with an overview of music history, and argues that Western music began to suffer from the time of Bach , after which twelve-tone equal temperament was adopted to the exclusion of other tuning systems, and abstract, instrumental music became the norm. Partch sought to bring vocal music back to prominence, and adopted tunings and scales he believed more suitable to singing. Inspired by Sensations of Tone , Hermann von Helmholtz 's book on acoustics and

He left the university, as it never accepted him as a member of the permanent staff, and there was little space for his growing stock of instruments. In 1949, pianist Gunnar Johansen allowed Partch to convert a smithy on his ranch in Blue Mounds, Wisconsin into a studio. Partch worked there with support from
455-691: A biography of Partch. Partch was first cousins with gag cartoonist Virgil Partch (1916–1984). Partch believed he was sterile due to childhood mumps , and he had a romantic relationship with the film actor Ramon Novarro . Partch met Danlee Mitchell while he was at the University of Illinois; Partch made Mitchell his heir, and Mitchell serves as the executive director of the Harry Partch Foundation. Dean Drummond and his group Newband took charge of Partch's instruments, and performed his repertoire. After Drummond's death in 2013, Charles Corey,
546-806: A cello. He used this instrument, dubbed the Adapted Viola, to write music using a scale with twenty-nine tones to the octave. Partch's earliest work to survive comes from this period, including works based on Biblical verse and Shakespeare, and Seventeen Lyrics of Li Po based on translations of the Chinese poetry of Li Bai . In 1932, Partch performed the music in San Francisco and Los Angeles with sopranos he had recruited. A February 9, 1932, performance at Henry Cowell 's New Music Society of California attracted reviews. A private group of sponsors sent Partch to New York in 1933, where he gave solo performances and won
637-462: A context. Instead, he saw it as a return to pre-Classical Western musical roots, in particular to the music of the ancient Greeks. By taking the principles he found in Helmholtz's book, he expanded his tuning system until it allowed for a division of the octave into 43 tones based on ratios of small integers. Partch uses the terms Otonality and Utonality to describe chords whose pitch classes are
728-445: A drift where the end of the piece is noticeably higher or lower in overall pitch rather than centered. Software solutions like Hermode Tuning often analyze solutions chord by chord instead of taking in the global context of the whole piece like it's theorized human players do. Since 2017, there has been research to address these problems algorithmically through dynamically adapted just intonation and machine learning. The human voice
819-455: A fifth and ascending by a major third: Since this is below C, one needs to move up by an octave to end up within the desired range of ratios (from 1:1 to 2:1): A 12 tone scale is obtained by removing one note for each couple of enharmonic notes. This can be done in four ways that have in common the removal of G ♭ , according to a convention which was valid even for C-based Pythagorean and quarter-comma meantone scales. Note that it

The Sousa Archives and Center for American Music in Urbana, Illinois, holds the Harry Partch Estate Archive, 1918–1991, which consists of Partch's personal papers, musical scores, films, tapes and photographs documenting his career as a composer, writer, and producer. It also holds the Music and performing Arts Library Harry Partch Collection, 1914–2007, which consists of books, music, films, personal papers, artifacts and sound recordings collected by
1001-573: A given letter name or swara, we have a difference of 81:80 (22 cents), which is the syntonic comma or the praman in Indian music theory. These notes are known as chala . The distance between two letter names comes in to sizes, poorna (256:243) and nyuna (25:24). One can see the symmetry, looking at it from the tonic, then the octave. (This is just one example of explaining a 22 Śhruti scale of tones. There are many different explanations.) Some fixed just intonation scales and systems, such as

#17330934197061092-444: A given scale may be tuned so that their frequencies form (relatively) small whole number ratios. The 5 limit diatonic major scale is tuned in such a way that major triads on the tonic , subdominant , and dominant are tuned in the proportion 4:5:6, and minor triads on the mediant and submediant are tuned in the proportion 10:12:15. Because of the two sizes of wholetone – 9:8 (greater wholetone) and 10:9 (lesser wholetone) –
1183-402: A limited number of notes. One can have more frets on a guitar (or keys on a piano) to handle both As, 9:8 with respect to G and 10:9 with respect to G so that A→C can be played as 6:5 while A→D can still be played as 3:2 . 9:8 and 10:9 are less than 1 / 53 of an octave apart, so mechanical and performance considerations have made this approach extremely rare. And
1274-439: A new key without retuning the instrument. For instance, if a piano is tuned in just intonation intervals and a minimum of wolf intervals for the key of G, then only one other key (typically E ) can have the same intervals, and many of the keys have a very dissonant and unpleasant sound. This makes modulation within a piece, or playing a repertoire of pieces in different keys, impractical to impossible. Synthesizers have proven
1365-693: A planned recording was blocked by the Yeats estate, which refused to grant permission to use Yeats's translation of Sophocles's play. In February 1953, Partch founded a studio, named Gate 5 , in an abandoned shipyard in Sausalito , California, where he composed, built instruments and staged performances. Subscriptions to raise money for recordings were organized by the Harry Partch Trust Fund, an organization put together by friends and supporters. The recordings were sold via mail order, as were later releases on
1456-472: A romantic relationship with the actor Ramon Novarro , then known by his birth name Ramón Samaniego; Samaniego broke off the affair when he started to become successful in his acting career. By 1925, Partch was putting his theory into practice by developing paper coverings for violin and viola with fingerings in just intonation, and wrote a string quartet using such tunings. He put his theories in words in May 1928 in
1547-413: A sequence of major thirds (ascending upward). For instance, in the first row of the table, there is an ascending fifth from D and A, and another one (followed by a descending octave) from A to E. This suggests an alternative but equivalent method for computing the same ratios. For instance, one can obtain A, starting from C, by moving one cell to the left and one upward in the table, which means descending by
1638-548: A seven-part Monophonic Cycle . On April 22, 1944, the first performance of his Americana series of compositions was given at Carnegie Chamber Music Hall put on by the League of Composers . Supported by Guggenheim and university grants, Partch took up residence at the University of Wisconsin from 1944 until 1947. This was a productive period, in which he lectured, trained an ensemble, staged performances, released his first recordings, and completed his book, now called Genesis of
1729-441: A twelve-tone scale, but it does so by involving ratios of very large numbers, corresponding to natural harmonics very high in the harmonic series that do not occur widely in physical phenomena. This tuning uses ratios involving only powers of 3 and 2, creating a sequence of just fifths or fourths , as follows: The ratios are computed with respect to C (the base note ). Starting from C, they are obtained by moving six steps (around
1820-449: A valuable tool for composers wanting to experiment with just intonation. They can be easily retuned with a microtuner . Many commercial synthesizers provide the ability to use built-in just intonation scales or to create them manually. Wendy Carlos used a system on her 1986 album Beauty in the Beast , where one electronic keyboard was used to play the notes, and another used to instantly set
1911-522: A way to expand the tone color palette of a piece of music. For example, the extended piano pieces The Well-Tuned Piano by La Monte Young and The Harp of New Albion by Terry Riley use a combination of very consonant and dissonant intervals for musical effect. In "Revelation", Michael Harrison goes even further, and uses the tempo of beat patterns produced by some dissonant intervals as an integral part of several movements. When tuned in just intonation, many fixed-pitch instruments cannot be played in
SECTION 20
#17330934197062002-411: Is a diminished fifth , close to half an octave, above the tonic C, which is a discordant interval; also its ratio has the largest values in its numerator and denominator of all tones in the scale, which make it least harmonious: All are reasons to avoid it. The following chart shows one way to obtain a 12 tone scale by removing one note for each pair of enharmonic notes. In this method one discards
2093-639: Is a measure of interval size. It is logarithmic in the musical frequency ratios. The octave is divided into 1200 steps, 100 cents for each semitone. Cents are often used to describe how much a just interval deviates from 12 TET . For example, the major third is 400 cents in 12 TET, but the 5th harmonic, 5:4 is 386.314 cents. Thus, the just major third deviates by −13.686 cents. Pythagorean tuning has been attributed to both Pythagoras and Eratosthenes by later writers, but may have been analyzed by other early Greeks or other early cultures as well. The oldest known description of
2184-476: Is a multiple of 7. The interval 9 / 8 is a 3 limit interval because the numerator and denominator are multiples of 3 and 2, respectively. It is possible to have a scale that uses 5 limit intervals but not 2 limit intervals, i.e. no octaves, such as Wendy Carlos 's alpha and beta scales. It is also possible to make diatonic scales that do not use fourths or fifths (3 limit), but use 5 and 7 limit intervals only. Thus,
2275-418: Is among the most pitch-flexible instruments in common use. Pitch can be varied with no restraints and adjusted in the midst of performance, without needing to retune. Although the explicit use of just intonation fell out of favour concurrently with the increasing use of instrumental accompaniment (with its attendant constraints on pitch), most a cappella ensembles naturally tend toward just intonation because of
2366-572: Is different from Wikidata All set index articles Harry Partch Harry Partch (June 24, 1901 – September 3, 1974) was an American composer, music theorist , and creator of unique musical instruments . He composed using scales of unequal intervals in just intonation , and was one of the first 20th-century composers in the West to work systematically with microtonal scales, alongside Lou Harrison . He built his own instruments in these tunings on which to play his compositions, and described

This twelve-tone scale is fairly close to equal temperament , but it does not offer much advantage for tonal harmony because only the perfect intervals (fourth, fifth, and octave) are simple enough to sound pure. Major thirds, for instance, receive the rather unstable interval of 81:64, sharp of the preferred 5:4 by an 81:80 ratio. The primary reason for its use
2548-428: Is infinite. Just intonations are categorized by the notion of limits . The limit refers to the highest prime number fraction included in the intervals of a scale. All the intervals of any 3 limit just intonation will be multiples of 3. So 6 / 5 is included in 5 limit, because it has 5 in the denominator. If a scale uses an interval of 21:20, it is a 7 limit just intonation, since 21
2639-685: Is largely tuned using just intonation. In China, the guqin has a musical scale based on harmonic overtone positions. The dots on its soundboard indicate the harmonic positions: 1 / 8 , 1 / 6 , 1 / 5 , 1 / 4 , 1 / 3 , 2 / 5 , 1 / 2 , 3 / 5 , 2 / 3 , 3 / 4 , 4 / 5 , 5 / 6 , 7 / 8 . Indian music has an extensive theoretical framework for tuning in just intonation. The prominent notes of

Since the advent of personal computing, there have been more attempts to solve
2821-429: Is that it is extremely easy to tune, as its building block, the perfect fifth, is the simplest and consequently the most consonant interval after the octave and unison. Pythagorean tuning may be regarded as a "three-limit" tuning system, because the ratios can be expressed as a product of integer powers of only whole numbers less than or equal to 3. A twelve-tone scale can also be created by compounding harmonics up to

The twelve remaining notes are repeated by increasing or decreasing their frequencies by a power of 2 (the size of one or more octaves ) to build scales with multiple octaves (such as the keyboard of a piano). A drawback of Pythagorean tuning is that one of the twelve fifths in this scale is badly tuned and hence unusable (the wolf fifth , either F ♯ –D ♭ if G ♭

By 14, he was composing for the piano. He developed an early interest in writing music for dramatic situations, and cited his lost composition Death and
3640-453: The overtone series (e.g. 11, 13, 17, etc.) Commas are very small intervals that result from minute differences between pairs of just intervals. For example, the (5 limit) 5:4 ratio is different from the Pythagorean (3 limit) major third (81:64) by a difference of 81:80, called the syntonic comma . The septimal comma , the ratio of 64:63, is a 7 limit interval which is

Since 5-limit has been the most prevalent just intonation used in western music, western musicians have subsequently tended to consider this scale to be the only version of just intonation. In principle, there are an infinite number of possible "just intonations," since the harmonic series

The age of specialization has given us a music drama that denies drama, and a drama that—contrary to the practices of all other peoples of the world—denies music. Partch rejected the Western concert music tradition, saying that the music of composers such as Beethoven "has only

There, his mother was killed in a trolley accident in 1920. He enrolled in the University of Southern California 's School of Music in 1920, but was dissatisfied with his teachers and left after the summer of 1922. He moved to San Francisco and studied books on music in

He was assisted for six months by composer Ben Johnston , who performed on Partch's recordings. In early 1951, Partch moved to Oakland for health reasons, and prepared for a production of King Oedipus at Mills College , with the support of designer Arch Lauterer . Performances of King Oedipus in March were extensively reviewed, but

For the first eight months of this period, he kept a journal which was published posthumously as Bitter Music . Partch included notation on the speech inflections of people he met in his travels. He continued to compose music, build instruments, and develop his book and theories, and make his first recordings. He had alterations made by sculptor and designer friend Gordon Newell to
4823-412: The base ratios. However, it can be easily extended by using higher positive and negative powers of the same numbers, such as 5 = 25, 5 = 1 ⁄ 25 , 3 = 27, or 3 = 1 ⁄ 27 . A scale with 25, 35 or even more pitches can be obtained by combining these base ratios. In Indian music , the just diatonic scale described above is used, though there are different possibilities, for instance for

They are computed in two steps: Note that the powers of 2 used in the second step may be interpreted as ascending or descending octaves . For instance, multiplying the frequency of a note by 2 means increasing it by 6 octaves. Moreover, each row of the table may be considered to be a sequence of fifths (ascending to the right), and each column
5005-420: The comfort of its stability. Barbershop quartets are a good example of this. The unfretted stringed instruments such as those from the violin family (the violin, the viola, and the cello), and the double bass are quite flexible in the way pitches can be adjusted. Stringed instruments that are not playing with fixed pitch instruments tend to adjust the pitch of key notes such as thirds and leading tones so that
5096-538: The diatonic scale above, produce wolf intervals when the approximately equivalent flat note is substituted for a sharp note not available in the scale, or vice versa. The above scale allows a minor tone to occur next to a semitone which produces the awkward ratio 32:27 for D→F, and still worse, a minor tone next to a fourth giving 40:27 for D→A. Flattening D by a comma to 10:9 alleviates these difficulties but creates new ones: D→G becomes 27:20, and D→B becomes 27:16. This fundamental problem arises in any system of tuning using

His non-Western orientation was particularly pronounced—sometimes explicitly, as when he set to music the poetry of Li Bai , or when he combined two Noh dramas with one from Ethiopia in The Delusion of the Fury . Partch believed that Western music of the 20th century suffered from over-specialization. He objected to the theatre of the day, which he believed had divorced music and drama, and he strove to create complete, integrated theatre works, in which he expected each performer to sing, dance, play instruments, and take on speaking parts. Partch used
5369-563: The fifth: namely, by multiplying the frequency of a given reference note (the base note) by powers of 2, 3, or 5, or a combination of them. This method is called five-limit tuning. To build such a twelve-tone scale (using C as the base note), we may start by constructing a table containing fifteen pitches: The factors listed in the first row and column are powers of 3 and 5, respectively (e.g., 1 / 9 = 3 ). Colors indicate couples of enharmonic notes with almost identical pitch. The ratios are all expressed relative to C in
5460-480: The first column of the table (labeled " 1 / 9 "). This scale is "asymmetric" in the sense that going up from the tonic two semitones we multiply the frequency by 9 / 8 , while going down from the tonic two semitones we do not divide the frequency by 9 / 8 . For two methods that give "symmetric" scales, see Five-limit tuning: Twelve-tone scale . The table above uses only low powers of 3 and 5 to build

From 1959 to 1962, Partch received further appointments from the University of Illinois, and staged productions of Revelation in the Courthouse Park in 1961 and Water! Water! in 1962. Though these two works were based, as King Oedipus had been, on Greek mythology , they modernized the settings and incorporated elements of popular music. Partch had support from several departments and organizations at

On recordings such as the soundtrack to Windsong , he used multitrack recording , which allowed him to play all the instruments himself. He never used synthesized or computer-generated sounds, though he had access to such technology. Partch scored six films by Madeline Tourtelot, starting with 1957's Windsong . He has been

In 1923 he came to reject the standard twelve-tone equal temperament of Western concert music when he discovered a translation of Hermann von Helmholtz 's Sensations of Tone .

Partch composed with scales dividing the octave into 43 unequal tones derived from the natural harmonic series ; these scales allowed for more tones of smaller intervals than in standard Western tuning, which uses twelve equal intervals to the octave. To play his music, Partch built many unique instruments , with such names as

In 1974, Partch was inducted into the Hall of Fame of the Percussive Arts Society , a music service organization promoting percussion education, research, performance and appreciation. In 2004, U.S. Highball was selected by the Library of Congress 's National Recording Preservation Board as "culturally, historically, or aesthetically significant". Partch made public his theories in his book Genesis of

In the first half (Castor) the music alternates between 4 and 5 beats to a bar, and there's usually a rest on the eighth of the nine beats. In the second half (Pollux) the rhythm's a bit more complicated, with six bars of 7 beats alternating with six bars of 9 beats until 234 beats are reached." Partch called himself "a philosophic music-man seduced into carpentry". The path towards Partch's use of various unique instruments
6188-445: The note, or pulling it out to sharpen the note while playing. Some natural horns also may adjust the tuning with the hand in the bell, and valved cornets, trumpets, Flugelhorns, Saxhorns, Wagner tubas, and tubas have overall and valve-by-valve tuning slides, like valved horns. Wind instruments with valves are biased towards natural tuning and must be micro-tuned if equal temperament is required. Other wind instruments, although built to
6279-509: The notion of limit is a helpful distinction, but certainly does not tell us everything there is to know about a particular scale. Pythagorean tuning , or 3 limit tuning, allows ratios including the numbers 2 and 3 and their powers, such as 3:2, a perfect fifth , and 9:4, a major ninth . Although the interval from C to G is called a perfect fifth for purposes of music analysis regardless of its tuning method, for purposes of discussing tuning systems musicologists may distinguish between
6370-411: The octaves slightly widened , and thus with no pure intervals at all. The phrase "just intonation" is used both to refer to one specific version of a 5-limit diatonic intonation , that is, Ptolemy's intense diatonic , as well to a whole class of tunings which use whole number intervals derived from the harmonic series . In this sense, "just intonation" is differentiated from equal temperaments and
6461-401: The perceived problem by trying to algorithmically solve what many professional musicians have learned through practice and intuition. Four of the main problems are that consonance cannot be perfect for some complex chords, chords can have internal consistency but clash with the overall direction of the piece, and naively adjusting the tuning only taking into account chords in isolation can lead to
6552-486: The perception of sound, Partch based his music strictly on just intonation . He tuned his instruments using the overtone series , and extended it up to the eleventh partial. This allowed for a larger number of smaller, unequal intervals than found in the Western classical music tradition's twelve-tone equal temperament . Partch's tuning is often classed as microtonality , as it allowed for intervals smaller than 100 cents , though Partch did not conceive his tuning in such
6643-432: The performers to sing, dance, speak, and play instruments. Partch described the theory and practice of his music in his book Genesis of a Music , which he had published first in 1947, and in an expanded edition in 1974. A collection of essays, journals, and librettos by Partch was published as posthumously as Bitter Music 1991. Partch partially supported himself with the sales of recordings, which he began making in
6734-427: The performers to sing, dance, speak, and play instruments. Ancient Greek theatre and Japanese Noh and kabuki heavily influenced his music theatre . Encouraged by his mother, Partch learned several instruments at a young age. By fourteen, he was composing, and in particular took to setting dramatic situations. He dropped out of the University of Southern California 's School of Music in 1922, dissatisfied with
6825-406: The pitches differ from equal temperament. Trombones have a slide that allows arbitrary tuning during performance. French horns can be tuned by shortening or lengthening the main tuning slide on the back of the instrument, with each individual rotary or piston slide for each rotary or piston valve, and by using the right hand inside the bell to adjust the pitch by pushing the hand in deeper to flatten
6916-544: The previous chord could be tuned to 8:10:12:13:18, using the A ;note from the 13th harmonic), which implies even more keys or frets. However the frets may be removed entirely – unfortunately, this makes in-tune fingering of many chords exceedingly difficult, due to the construction and mechanics of the human hand – and the tuning of most complex chords in just intonation is generally ambiguous. Some composers deliberately use these wolf intervals and other dissonant intervals as
7007-500: The problem of how to tune complex chords such as C (C→E→G→A→D), in typical 5 limit just intonation, is left unresolved (for instance, A could be 4:3 below D (making it 9:8, if G is 1) or 4:3 above E (making it 10:9, if G is 1) but not both at the same time, so one of the fourths in the chord will have to be an out-of-tune wolf interval). Most complex (added-tone and extended) chords usually require intervals beyond common 5 limit ratios in order to sound harmonious (for instance,
7098-405: The pure 3 / 2 ratio. This is mentioned by Schenker in reference to the teaching of Bruckner. For a justly tuned diatonic minor scale, the mediant is tuned 6:5 and the submediant is tuned 8:5. It would include a tuning of 9:5 for the subtonic . For example, on A: There are several ways to create a just tuning of the twelve-tone scale. Pythagorean tuning can produce
7189-451: The quality of his teachers. He took to self-study in San Francisco's libraries, where he discovered Hermann von Helmholtz 's Sensations of Tone , which convinced him to devote himself to music based on scales tuned in just intonation . In 1930, he burned all his previous compositions in a rejection of the European concert tradition. Partch frequently moved around the US. Early in his career, he
7280-422: The root note to which all intervals were tuned, which allowed for modulation. On her 1987 lecture album Secrets of Synthesis there are audible examples of the difference in sound between equal temperament and just intonation. Many singers (especially barbershop quartets) and fretless instrument players naturally aim for a more just intonation when playing: In trying to get a more just system for instruments that
7371-460: The sixth pitch ( dha ), and further modifications may be made to all pitches excepting sa and pa . Some accounts of Indian intonation system cite a given 12 swaras being divided into 22 shrutis . According to some musicians, one has a scale of a given 12 pitches and ten in addition (the tonic, shadja ( sa ), and the pure fifth, pancham ( pa ), are inviolate (known as achala in Indian music theory): Where we have two ratios for
7462-605: The spoken inflection in Yeats's recitation of the text. He built a keyboard instrument, the Chromatic Organ, which used a scale with forty-three tones to the octave. He met musicologist Kathleen Schlesinger , who had recreated an ancient Greek kithara from images she found on a vase at the British Museum . Partch made sketches of the instrument in her home, and discussed ancient Greek music theory with her. Partch returned to
7553-447: The staff of the Music and Performing Arts Library and the University of Illinois School of Music documenting the life and career of Harry Partch, and those associated with him, throughout his career as a composer and writer. Partch's notation is an obstacle, as it mixes a sort of tablature with indications of pitch ratios. This makes it difficult for those trained in traditional Western notation, and gives no visual indication as to what
7644-621: The subject of a number of documentary films. Just intonation In Western musical practice, bowed instruments such as violins, violas, cellos, and double basses are tuned using pure fifths or fourths. In contrast, keyboard instruments are rarely tuned using only pure intervals—the desire for different keys to have identical intervals in Western music makes this impractical. Some instruments of fixed pitch, such as electric pianos, are commonly tuned using equal temperament , in which all intervals other than octaves consist of irrational-number frequency ratios. Acoustic pianos are usually tuned with
7735-606: The support of composers Roy Harris , Charles Seeger , Henry Cowell, Howard Hanson , Otto Luening , Walter Piston , and Aaron Copland . Partch unsuccessfully applied for Guggenheim grants in 1933 and 1934. The Carnegie Corporation of New York granted him $ 1500 so he could do research in England. He gave readings at the British Museum and traveled in Europe. He met W. B. Yeats in Dublin, whose translation of Sophocles ' King Oedipus he wanted to set to his music; he studied
7826-687: The university, but continuing hostility from the music department convinced him to leave and return to California. Partch set up a studio in late 1962 in Petaluma , California, in a former chick hatchery. There he composed And on the Seventh Day, Petals Fell in Petaluma . He left northern California in summer 1964, and spent his remaining decade in various cities in southern California. He rarely had university work during this period, and lived on grants, commissions, and record sales. A turning point in his popularity
7917-405: The words "ritual" and "corporeal" to describe his theatre works—musicians and their instruments were not hidden in an orchestra pit or offstage, but were a visual part of the performance. Partch's approach to rhythm ranged from unspecified to complex. In Seventeen Lyrics of Li Po for the Adapted Viola, Partch "doesn't bother with rhythmic notation at all, but simply directs performers to follow
8008-617: Was a transient worker, and sometimes a hobo ; later he depended on grants, university appointments, and record sales to support himself. In 1970, supporters created the Harry Partch Foundation to administer Partch's music and instruments. On June 24, 1901, Partch was born in Oakland, California . His parents were Virgil Franklin Partch (1860–1919) and Jennie (née Childers, 1863–1920). The Presbyterian couple were missionaries , serving in China from 1888 to 1893, and again from 1895 to 1900, when they fled
8099-421: Was gradual. He began in the 1920s using traditional instruments, and wrote a string quartet in just intonation (now lost). He had his first specialized instrument built for him in 1930—the Adapted Viola, a viola with a cello's neck fitted on it. Most of Partch's works exclusively used the instruments he had created. Some works made use of unaltered standard instruments such as clarinet or cello; Revelation in
8190-453: Was the 1969 Columbia LP The World of Harry Partch , the first modern recording of Partch's music and his first release on a major record label. His final theater work was Delusion of the Fury , which incorporated music from Petaluma , and was first produced at the University of California in early 1969. In 1970, the Harry Partch Foundation was founded to handle the expenses and administration of Partch's work. His final completed work
8281-541: Was the soundtrack to Betty Freeman 's The Dreamer that Remains . He retired to San Diego in 1973, where he died after suffering a heart attack on September 3, 1974. The same year, a second edition of Genesis of a Music was published with extra chapters about work and instruments Partch made since the book's original publication. In 1991, Partch's journals from June 1935 to February 1936 were discovered and published—journals that Partch had believed to have been lost or destroyed. In 1998, musicologist Bob Gilmore published
