As long as such a plurality of approaches persists, the task of finding one all-encompassing method may well elude theorists and composers alike. The history of notating microtonal music has been one replete with idiosyncrasies. 1928), is notable for his amalgamation of both of these significant trends into a personal mode of expression for which he developed an exhaustive, and complicated, notational scheme, which has since been adopted by numerous composers in his region (New England). Others working with pianos (including the aforementioned Carrillo) have experimented with stacking keyboards, altering the layout of the keyboard, or changing the pitch designation of the individual keys within the octave.Īnother American, Ezra Sims (b. 1935) found another solution with his Microtonal Fantasy: scored for one performer, two pianos are placed at ninety-degree angles to one another (and tuned a quarter-tone apart) so that they could be played simultaneously. When he scored this work he avoided any need for a particular microtonal notation: in effect the part for the pianist with the re-tuned instrument is similar to tablature since the microtones are not indicated, but sound when the correct keys are depressed. Therefore, in order to achieve an integrated melodic and harmonic conception for the compositions, the two performers and instruments had to be conceived as if one. In this case, the two performers play on pianos that are equal-tempered, but a quarter-tone apart from one another. The quintessential American maverick composer, Charles Ives (1874-1954), first explored the possibilities of microtones in a holistic fashion in his Three Quarter-Tone Pieces for Two Pianos. Carrillo's work culminated in his full length, quarter-tone Mass, while Hába's opera, The Mother (also in quarter-tones) is perhaps the most exhaustive implementation of a microtonal harmonic system of its type in the literature. These scales (with 24 steps if quarter-tone, or 48 if eighth-tone) are then applied to largely traditional forms, with the extended interval palette enhancing expressive subtleties of melodic and harmonic configurations. Others, such as the Mexican composer Julián Carrillo (1875-1965) and the Czech, Alois Hába (1893-1973), initially began their work by subdividing the equal-tempered scale (based on 12 semi-tones) proportionally into quarter-, third-, eighth-tones, or even finer gradations. 1955), seek to utilize the more scientifically accurate acoustical relationship between pitches based on the natural harmonic series. In order to understand microtonal principles, we must first distinguish the multitude of perspectives that microtonal composition can take.Ĭomposers interested in intonation systems other than the standard equal-tempered one practiced in the Western Classical tradition, particularly numerous Americans composers, including Harry Partch (1901-74), Benjamin Johnston (b. It has as many interpretations, modes of expression, and techniques as tonal music. Microtonality is not a genre, or a technique, or a style.
