Tonality is the arrangement of pitches and / or chords of a musical work in a hierarchy of perceived relations, stabilities, attractions, and directionality.. In this hierarchy, the single pitch or the root of a triad with the greatest stability in a melody or in its harmony is called the tonic.
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]
For instance, the fairly common assertion that "tonality" is a universal of all music may necessarily require an expansive definition of tonality. A pulse is sometimes taken as a universal, yet there exist solo vocal and instrumental genres with free and improvisational rhythm—no regular pulse [ 23 ] —one example being the alap section of ...
The chromatic expansion of tonality which characterizes much of nineteenth century music is illustrated in miniature by the substitution of a chromatic harmony for an expected diatonic harmony. This technique resembles the deceptive cadence, which involves the substitution of another diatonic chord for the expected diatonic goal harmony. [32] ...
In music, function (also referred to as harmonic function [1]) is a term used to denote the relationship of a chord [2] or a scale degree [3] to a tonal centre.Two main theories of tonal functions exist today:
In music, modulation is the change from one tonality (tonic, or tonal center) to another. This may or may not be accompanied by a change in key signature (a key change). Modulations articulate or create the structure or form of many pieces, as well as add interest.
Pandiatonicism is a musical technique of using the diatonic (as opposed to the chromatic) scale without the limitations of functional tonality. Music using this technique is pandiatonic . History
Atonality in its broadest sense is music that lacks a tonal center, or key. [1] Atonality, in this sense, usually describes compositions written from about the early 20th-century to the present day, where a hierarchy of harmonies focusing on a single, central triad is not used, and the notes of the chromatic scale function independently of one another.
