. In ''Revising the musical equal temperament,'' Haye Hinrichsen defines equal temperament as “the frequency ratios of all intervals are invariant under transposition (translational shifts along the keyboard), i.e., to be constant. The standard twelve-tone ''equal temperament'' (ET), which was originally invented in ancient China and rediscovered in Europe in the 16th century, is determined by two additional conditions. Firstly the octave is divided into twelve semitones. Secondly the octave, the most fundamental of all intervals, is postulated to be pure (beatless), as described by the frequency ratio 2:1.”


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 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, violi ...
, writing in Spanish or French, coined the terms ''microtono''/''micro-ton'' and ''microtonalismo''/''micro-tonalité''. In French, the usual term is the somewhat more self-explanatory ''micro-intervalle'', and French sources give the equivalent German and English terms as ''Mikrointervall'' (or ''Kleinintervall'') and ''micro interval'' (or ''microtone''), respectively. "Microinterval" is a frequent alternative in English, especially in translations of writings by French authors and in discussion of music by French composers. In English, the two terms "microtone" and "microinterval" are synonymous. The English analogue of the related French term, ''micro-intervalité'', however, is rare or nonexistent, normally being translated as "microtonality"; in French, the terms ''micro-ton'', ''microtonal'' (or ''micro-tonal''), and ''microtonalité'' are also sometimes used, occasionally mixed in the same passage with ''micro-intervale'' and ''micro-intervalité''.
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 that was adopted by many microtonal composers afte ...

objected that "'heterotone' would be a better name for śruti than the usual translation 'microtone'". Modern Indian researchers yet write: "microtonal intervals called shrutis". In Germany, Austria, and Czechoslovakia in the 1910s and 1920s the usual term continued to be ''Viertelton-Musik'' (quarter tone music), and the type of intervallic structure found in such music was called the ''Vierteltonsystem'', which was (in the mentioned region) regarded as the main term for referring to music with microintervals, though as early as 1908 Georg Capellan had qualified his use of "quarter tone" with the alternative term "Bruchtonstufen (Viertel- und Dritteltöne)" (fractional degrees (quarter and third tones)). Despite the inclusion of other fractions of a whole tone, this music continued to be described under the heading "Vierteltonmusik" until at least the 1990s, for example in the twelfth edition of the ''

Another Russian authors use more international adjective 'microtonal' and rendered it in Russian as 'микротоновый', but not 'microtonality' ('микротональность'). However, the terms 'микротональность' and 'микротоника' are also used. Some authors writing in French have adopted the term "micro-intervallique" to describe such music. Italian musicologist Luca Conti dedicated two his monographs to ''microtonalismo'', which is the usual term in Italian, and also in Spanish (e.g., as found in the title of Rué 000.
