Diatonic Set Theory
Diatonic set theory is a subdivision or application of set theory (music), musical set theory which applies the techniques and musical analysis, analysis of discrete mathematics to properties of the diatonic collection such as maximal evenness, Myhill's property, well formed generated collection, well formedness, the deep scale property, cardinality equals variety, and structure implies multiplicity. The name is something of a misnomer as the concepts involved usually apply much more generally, to any periodically repeating scale. Music theorists working in diatonic set theory include Eytan Agmon, Gerald J. Balzano, Norman Carey, David Clampitt, John Clough, Jay Rahn, and mathematician Jack Douthett. A number of key concepts were first formulated by David Rothenberg (the Rothenberg propriety), who published in the journal ''Mathematical Systems Theory'', and Erv Wilson, working entirely outside of the academic world.

Set Theory (music)
Musical set theory provides concepts for categorizing musical objects and describing their relationships. Howard Hanson first elaborated many of the concepts for analyzing tonal music. Other theorists, such as Allen Forte, further developed the theory for analyzing atonal music, drawing on the twelve-tone theory of Milton Babbitt. The concepts of musical set theory are very general and can be applied to tonal and atonal styles in any equal temperament tuning system, and to some extent more generally than that. One branch of musical set theory deals with collections ( sets and permutations) of pitches and pitch classes (pitch-class set theory), which may be ordered or unordered, and can be related by musical operations such as transposition, melodic inversion, and complementation. Some theorists apply the methods of musical set theory to the analysis of rhythm as well. Comparison with mathematical set theory Although musical set theory is often thought to involve the ...

Erv Wilson
Ervin Wilson (June 11, 1928 – December 8, 2016) was a Mexican/ American (dual citizen) music theorist. Early life Ervin Wilson was born iColonia Pacheco a small village in the remote mountains of northwest Chihuahua, Mexico, where he lived until the age of fifteen. His mother taught him to play the reed organ and to read musical notation. He began to compose at an early age, but immediately discovered that some of the sounds he was hearing mentally could not be reproduced by the conventional intervals of the organ. As a teenager, he began to read books on Indian music, developing an interest in concepts of raga. While he was in the Air Force in Japan, a chance meeting with a total stranger introduced him to musical harmonics, which changed the course of his life and work. Influenced by the work of Joseph Yasser, Wilson began to think of the musical scale as a living process—like a crystal or plant. Works Despite his avoidance of academia, Wilson has been influential on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Rothenberg
David Rothenberg (born 1962) is a professor of philosophy and music at the New Jersey Institute of Technology, with a special interest in animal sounds as music. He is also a composer and jazz musician whose books and recordings reflect a longtime interest in understanding other species such as singing insects by making music with them. Life and work Rothenberg graduated from Harvard and took his PhD from Boston University. Looking back at his high school years in the 1970s, Rothenberg told Claudia Dreifus of ''The New York Times'', "I was influenced by saxophonist Paul Winter's ''Common Ground'' album, which had his own compositions with whale and bird sounds mixed in. That got me interested in using music to learn more about the natural world." As an undergraduate at Harvard, Rothenberg created his own major to combine music with communication. He traveled in Europe after graduation, playing jazz clarinet. Listening to the recorded song of a hermit thrush, he heard s ...

In Theory Only
''In Theory Only'' () was a peer-reviewed academic journal specializing in music theory and analysis. It began publication in 1975, under the auspices of graduate students in music theory at the University of Michigan School of Music, Theatre & Dance, making it the first of the graduate-student produced theory journals to debut in the U.S. (followed two years later by ''Indiana Theory Review'').David Carson Berry, "Schenkerian Theory in the United States: A Review of Its Establishment and a Survey of Current Research Topics," ''Zeitschrift der Gesellschaft für Musiktheorie'' 2/2–3 (2005), 111 (online version at http://www.gmth.de/zeitschrift/artikel/206.aspx). The journal initially employed the subtitle "Newsletter of the Michigan Music Theory Society" (later dropped). The journal ceased regular publication in 1997, but had one final issue published in 2007.

Kraig Grady
Kraig Grady (born 1952) is a US-Australian composer/ sound artist. He has composed and performed with an ensemble of microtonal instruments of his own design and also worked as a shadow puppeteer, tuning theorist, filmmaker, world music radio DJ and concert promoter. His works feature his own ensembles of acoustic instruments, including metallophones, marimbas, hammered dulcimers and reed organs tuned to microtonal just intonation scales. His compositions include accompaniments for silent films and shadow plays. An important influence in the development of Grady's music was Harry Partch, like Grady, a musician from the Southwest, and a composer of theatrical works in Just Intonation for self-built instruments. Many of his compositions use unusual meters of very extended lengths. Biography Born in Montebello, California in 1952, Grady began composing while still in his teens. After studies with Nicolas Slonimsky, Dean Drummond, Dorrance Stalvey and Byong-Kon Kim, he produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perspectives Of New Music
''Perspectives of New Music'' (PNM) is a peer-reviewed academic journal specializing in music theory Music theory is the study of theoretical frameworks for understanding the practices and possibilities of music. ''The Oxford Companion to Music'' describes three interrelated uses of the term "music theory": The first is the "Elements of music, ... and analysis. It was established in 1962 by Arthur Berger and Benjamin Boretz (who were its initial editors-in-chief). ''Perspectives'' was first published by the Princeton University Press, initially supported by the Fromm Music Foundation.David Carson Berry, "''Journal of Music Theory'' under Allen Forte's Editorship," '' Journal of Music Theory'' 50/1 (2006), 21, n49. The first issue was favorably reviewed in the '' Journal of Music Theory'', which observed that Berger and Boretz had produced "a first issue which sustains such a high quality of interest and cogency among its articles that one suspects the long delay precedin ...

Generic And Specific Intervals
In diatonic set theory a generic interval is the number of scale steps between notes of a collection or scale. The largest generic interval is one less than the number of scale members. (Johnson 2003, p. 26) A specific interval is the clockwise distance between pitch classes on the chromatic circle ( interval class), in other words the number of half steps between notes. The largest specific interval is one less than the number of "chromatic" pitches. In twelve tone equal temperament the largest specific interval is 11. (Johnson 2003, p. 26) In the diatonic collection the generic interval is one less than the corresponding diatonic interval: * Adjacent intervals, seconds, are 1 * Thirds = 2 * Fourths = 3 * Fifths = 4 * Sixths = 5 * Sevenths = 6 The largest generic interval in the diatonic scale being 7 − 1 = 6. Myhill's property Myhill's property is the quality of musical scales or collections with exactly two specific intervals for every generic interval, ...

Diatonic And Chromatic
Diatonic and chromatic are terms in music theory that are used to characterize Scale (music), scales. The terms are also applied to musical instruments, Interval (music), intervals, Chord (music), chords, Musical note, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the Common practice period, common practice music of the period 1600–1900. These terms may mean different things in different contexts. Very often, ''diatonic'' refers to musical elements derived from the modes and transpositions of the "white note scale" C–D–E–F–G–A–B. In some usages it includes all forms of heptatonic scale that are in common use in Western music (the major, and all forms of the minor). ''Chromatic'' most often refers to structures derived from the chromatic scale in 12-tone equal temperament, which consists of all semitones. Historically, however, it had other senses, referring in Ancient Greek mus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bisector (music)
In diatonic set theory, a bisector divides the octave approximately in half (the equal tempered tritone is exactly half the octave) and may be used in place of a generated collection, generator to derive Set (music), collections for which structure implies multiplicity is not true such as the ascending melodic minor, harmonic minor, and octatonic scales. Well formed generated collections generators and bisectors coincide, such as the perfect fifth (circle of fifths) in the diatonic collection. The term was introduced by Jay Rahn (1977), who considers any division between one and two thirds as approximately half (major third to minor sixth or 400 to 800 cents) and who applied the term only the equally spaced collections. Clough and Johnson both adapt the term to apply to generic interval, generic scale steps. Rahn also uses ''aliquant bisector'' for bisectors which may be used to generate every note in a collection, in which case the bisector and the number of notes must be coprime. ...

Musical Analysis
Musical analysis is the study of musical structure in either compositions or performances. According to music theorist Ian Bent, music analysis "is the means of answering directly the question 'How does it work?'". The method employed to answer this question, and indeed exactly what is meant by the question, differs from analyst to analyst, and according to the purpose of the analysis. According to Bent, "its emergence as an approach and method can be traced back to the 1750s. However it existed as a scholarly tool, albeit an auxiliary one, from the Middle Ages onwards." The principle of analysis has been variously criticized, especially by composers, such as Edgard Varèse's claim that, "to explain by means of nalysisis to decompose, to mutilate the spirit of a work". Analyses Some analysts, such as Donald Tovey (whose '' Essays in Musical Analysis'' are among the most accessible musical analyses) have presented their analyses in prose. Others, such as Hans Keller (who d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
