Microtonal
Microtonality is the use in music of microtones — intervals smaller than a semitone, also called "microintervals". It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave. In other words, a microtone may be thought of as a note that falls "between the keys" of a piano tuned in equal temperament. Terminology Microtone ''Microtonal music'' can refer to any music containing microtones. The words "microtone" and "microtonal" were coined before 1912 by Maud MacCarthy Mann in order to avoid the misnomer " quarter tone" when speaking of the srutis of Indian music. Prior to this time the term "quarter tone" was used, confusingly, not only for an interval actually half the size of a semitone, but also for all intervals (considerably) smaller than a semitone. It may have been even slightly earlier, perhaps as early as 1895, that the Mexican composer Julián Carrillo, writing in Spanish or Frenc ...

Ezra Sims
Ezra Sims (January 16, 1928 in Birmingham, Alabama — January 30, 2015 in Boston, Massachusetts) was one of the pioneers in the field of microtonal composition. He invented a system of notation In linguistics and semiotics, a notation system is a system of graphics or symbols, Character_(symbol), characters and abbreviated Expression (language), expressions, used (for example) in Artistic disciplines, artistic and scientific disciplines ... that was adopted by many microtonal composers after him, including Joseph Maneri. His professional debut (12 note ET music) occurred on a Composers Forum program in New York, 1959. In 1960, compelled by his ear, he began writing microtonal music, and continued to do so for the rest of his life, with the occasional exception being taped music for dancers. His last composition in quarter tones (his sixth microtonal one) was his ''Third Quartet'' (1962). Since 1971, whatever music he has composed that is not purely electronic has employed a sys ...

Equal Temperament
An equal temperament is a musical temperament or Musical tuning#Tuning systems, tuning system that approximates Just intonation, just intervals by dividing an octave (or other interval) into steps such that the ratio of the frequency, frequencies of any adjacent pair of notes is the same. This system yields Pitch (music), pitch steps perceived as equal in size, due to the logarithmic changes in pitch frequency. In classical music and Western music in general, the most common tuning system since the 18th century has been 12 equal temperament (also known as ''12 tone equal temperament'', ' or ', informally abbreviated as ''12 equal''), which divides the octave into 12 parts, all of which are equal on a logarithmic scale, with a ratio equal to the twelfth root of two, 12th root of 2, (\sqrt[12] ≈ 1.05946). That resulting smallest interval, the width of an octave, is called a semitone or half step. In Western world, Western countries the term ''equal temperamen ...

Quarter Tone
A quarter tone is a pitch halfway between the usual notes of a chromatic scale or an interval about half as wide (orally, or logarithmically) as a semitone, which itself is half a whole tone. Quarter tones divide the octave by 50 cents each, and have 24 different pitches. Quarter tones have their roots in the music of the Middle East and more specifically in Persian traditional music. However, the first evidenced proposal of the equally-tempered quarter tone scale, or 24 equal temperament, was made by 19th-century music theorists Heinrich Richter in 1823 Julian Rushton, "Quarter-Tone", ''The New Grove Dictionary of Music and Musicians'', second edition, edited by Stanley Sadie and John Tyrrell (London: Macmillan, 2001). and Mikhail Mishaqa about 1840. Composers who have written music using this scale include: Pierre Boulez, Julián Carrillo, Mildred Couper, George Enescu, Alberto Ginastera, Gérard Grisey, Alois Hába, Ljubica Marić, Charles Ives, Tristan Murail, Kr ...

Julián Carrillo
Julián Carrillo Trujillo (January 28, 1875 – September 9, 1965) was a Mexican composer,Camp, Roderic Ai (1995). "Carrillo (Flores), Nabor" on ''Mexican Political Biographies, 1935–1993: Third Edition'', p. 121. . conductor, violinist and music theorist, famous for developing a theory of microtonal music which he dubbed "The Thirteenth Sound" ( Sonido 13). Biography Carrillo was born on January 28, 1875, in Ahualulco, a village in the state of San Luis Potosí. He was the last of the 19 children of Nabor Carrillo and Antonia Trujillo. Early education Carrillo sang in the children's choir of Ahualulco's church. The choir's conductor, Flavio F. Carlos, encouraged him to study music in the state capital, San Luis Potosí. He planned to study for two years, then return to Ahualulco as the church's singer, but problems prevented this plan. He arrived to San Luis Potosí City in 1885 and began to study with Flavio F.

Interval (music)
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord. In Western music, intervals are most commonly differences between notes of a diatonic scale. Intervals between successive notes of a scale are also known as scale steps. The smallest of these intervals is a semitone. Intervals smaller than a semitone are called microtones. They can be formed using the notes of various kinds of non-diatonic scales. Some of the very smallest ones are called commas, and describe small discrepancies, observed in some tuning systems, between enharmonically equivalent notes such as C and D. Intervals can be arbitrarily small, and even imperceptible to the human ear. In physical terms, an interval is the ratio between two sonic fr ...

Accidental (music)
In musical notation, an accidental is a symbol that indicates an alteration of a given Pitch (music), pitch. The most common accidentals are the Flat (music), flat () and the Sharp (music), sharp (), which represent alterations of a semitone, and the Natural (music), natural (), which cancels a sharp or flat. Accidentals alter the pitch of individual Degree (music), scale tones in a given key signature; the sharps or flats in the key signature itself are not called accidentals. An accidental applies to the note that immediately follows it and to subsequent instances of that note in the same Bar (music), measure, unless it is canceled by another accidental. A sharp raises a note's pitch by a semitone and a flat lowers it by a semitone. Double flats () or sharps () may also be used, altering the unmodified note by two semitones. If a note with an accidental is Tie (music), tied, the accidental continues to apply, even if the note it is tied to is in the next measure. If a note has a ...

Flat (music)
In music, flat means lower in pitch. It may either be used in a general sense to mean any lowering of pitch, or to specifically refer to lowering pitch by a semitone. A flat is the opposite of a sharp () which indicates a raised pitch in the same way. The flat symbol () appears in key signatures to indicate which notes are flat throughout a section of music, and also in front of individual notes as an accidental, indicating that the note is flat until the next bar line. Pitch change The symbol is a stylised lowercase ''b'', derived from Italian ''be molle'' for "soft B" and German ''blatt'' for "planar, dull". It indicates that the note to which it is applied is played one semitone lower. In the standard modern tuning system, 12 tone equal temperament, this corresponds to 100 cents. In older tuning systems (from the 16th and 17th century), and in modern microtonal tunings, the difference in pitch indicated by a sharp or flat is normally smaller than the stan ...

Comma (music)
In music theory, a comma is a very small interval (music), interval, the difference resulting from Musical tuning, tuning one note (music), note two different ways. Traditionally, there are two most common commata; the syntonic comma (80:81), "the difference between a just intonation, just major 3rd and four just perfect 5ths less two octaves", and the Pythagorean comma (524288:531441, approximately 73:74), "the difference between twelve 5ths and seven octaves". The word ''comma'' used without qualification refers to the syntonic comma, which can be defined, for instance, as the difference between an F tuned using the D-based Pythagorean tuning system, and another F tuned using the D-based quarter-comma meantone tuning system. Pitches separated by either comma are considered the same note because conventional notation does not distinguish Pythagorean intervals from 5-limit intervals. Other intervals are considered commas because of the enharmonic equivalences of a tuning system. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schisma
In music, the schisma (also spelled ''skhisma'') is the interval between the syntonic comma (81:80) and the Pythagorean comma which is slightly larger. It equals or ≈ 1.00113, which corresponds to 1.9537 cents (). It may also be defined as: * the difference (in cents) between 8 justly tuned perfect fifths plus a justly tuned major third and 5 octaves; * the ratio of major limma to the Pythagorean limma; * the ratio of the syntonic comma and the diaschisma. ''Schisma'' is a Greek word meaning a split or crack (see schism) whose musical sense was introduced by Boethius at the beginning of the 6th century in the 3rd book of his ''De institutione musica''. Boethius was also the first to define the diaschisma. Andreas Werckmeister defined the ''grad'' as the twelfth root of the Pythagorean comma, or equivalently the difference between the justly tuned fifth (3:2) and the equally tempered fifth of 700 cents (2). This value, 1.955 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesis
In classical music from Western culture, a diesis ( or enharmonic diesis, plural dieses ( , or "difference"; Greek: "leak" or "escape" is either an accidental (see sharp), or a very small musical interval, usually defined as the difference between an octave (in the ratio 2:1) and three justly tuned major thirds (tuned in the ratio 5:4), equal to 128:125 or about 41.06 cents. In 12-tone equal temperament (on a piano for example) three major thirds in a row equal an octave, but three justly-tuned major thirds fall quite a bit narrow of an octave, and the diesis describes the amount by which they are short. For instance, an octave (2:1) spans from C to C′, and three justly tuned major thirds (5:4) span from C to B (namely, from C, to E, to G, to B). The difference between C-C′ (2:1) and C-B (125:64) is the diesis (128:125). Notice that this coincides with the interval between B and C′, also called a diminished second. As a comma, the above-mentioned 128:125 r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
