Atonality

Atonality describes music that departs from the system of tonal hierarchies, which characterizes the sound of classical European music between the seventeenth and nineteenth centuries. Atonality usually describes compositions written from about 1900 to the present day, where the hierarchy of tonal centers is not used as the primary way to organize a work. Tonal centers gradually replaced modal organization starting in the 1500s and culminated with the establishment of the major-minor key system in the late 1600s and early 1700s.

Composing atonal music

Setting out to compose atonal music may seem complicated because of both the vagueness and generality of the term. Additionally George Perle (1962) explains that, "the 'free' atonality that preceded dodecaphony precludes by definition the possibility of self-consistent, generally applicable compositional procedures." (p.9) However, he provides one example as a way to compose atonal pieces, a pre-twelve tone technique piece by Anton Webern, which rigorously avoids anything that suggests tonality, to choose pitches that do not imply tonality. In other words, reverse the rules of the common practice period so that what was not allowed is required and what was required is not allowed. This is what was done by Charles Seeger in his explanation of dissonant counterpoint, which is a way to write atonal counterpoint.

Further, he agrees with Oster and Katz that, "the abandonment of the concept of a root-generator of the individual chord is a radical development that renders futile any attempt at a systematic formulation of chord structure and progression in atonal music along the lines of traditional harmonic theory." (p.31) Atonal compositional techniques and results "are not reducible to a set of foundational assumptions in terms of which the compositions that are collectively designated by the expression 'atonal music' can be said to represent 'a system' of composition." (p.1)

Perle also points out that structural coherence is most often achieved through operations on intervallic cells. A cell "may operate as a kind of microcosmic set of fixed intervallic content, statable either as a chord or as a melodic figure or as a combination of both. Its components may be fixed with regard to order, in which event it may be employed, like the twelve-tone set, in its literal transformations... Individual tones may function as pivotal elements, to permit overlapping statements of a basic cell or the linking of two or more basic cells." (pp.9-10)
