The word tonality may describe any systematic organization of pitch phenomena in any music at all, including pre-17th century western music as well as much non-western music, such as music based on the slendro and pelog pitch collections of Indonesian gamelan, or employing the modal nuclei of the Arabic maqam or the Indian raga system.
In music theory, the key of a piece is the group of pitches, or scale, that forms the basis of a musical composition in Western classical music, art music, and pop music. Tonality (from "Tonic") or key: Music which uses the notes of a particular scale is said to be "in the key of" that scale or in the tonality of that scale. [1]
Since modulation is defined as a change of tonic (tonality or tonal center), the change between minor and its parallel major or the reverse is technically not a modulation but a change in mode. Major tonic harmony that concludes music in minor contains what is known as a Picardy third.
In describing the tonality of early music, the term "mode" (or "tone") refers to any of eight sets of pitch intervals that may form a musical scale, representing the tonality of a piece and associated with characteristic melodic shapes (psalm tones) in Gregorian chant.
Thus otonality and utonality can be viewed as extensions of major and minor tonality respectively. However, whereas standard music theory views a minor chord as being built up from the root with a minor third and a perfect fifth , a utonality is viewed as descending from what's normally considered the "fifth" of the chord, [ 9 ] so the ...
Slonimsky himself, making fun of the definition, quoted a professor calling pandiatonicism "C-major that sounds like hell". [ 17 ] Examples of pandiatonicism include the harmonies Aaron Copland used in his populist work, Appalachian Spring , [ 18 ] and the minimalist music by Steve Reich , Philip Glass , and the later works of John Adams .
(3)As described above (Does music have a syntax?), music has a hierarchical structure in terms of pitch organization and organization of tensioning and releasing in music. Pitch organization concerning chords means, that in a musical phrase the tonic is the most stable chord and experienced as the resting point.
Post-tonal music theory is the set of theories put forward to describe music written outside of, or 'after', the tonal system of the common practice period.It revolves around the idea of 'emancipating dissonance', that is, freeing the structure of music from the familiar harmonic patterns that are derived from natural overtones.
