The abandonment of tonality in the early 20th cent. by Schoenberg, Berg, Webern, Ives, and many other composers was the next logical step in the evolution of musical style. To compensate for this lack of one principle of order, another had to be substituted. The most successful one proposed thus far is that of dodecaphony, or twelve-tone music (see serial music). Atonality is also used by some to designate all music that has discarded the earlier principle of tonality, whether organized in some other way or not. Others use it only for works such as Schoenberg's Pierrot Lunaire, in which notes and harmonies are used in a free, nonsystematic manner. By the close of the 20th cent., atonal music has become a part of the classical repertoire. However, some critics feel that this music's austerity and rigor lessen its expressive potential, and it has failed to attract a large audience.

In music, the absence of functional harmony as a primary structural element. Probably originally a pejorative term applied to music of extreme chromaticism, it has become the most widely used descriptive term for 20th-century music whose connection with tonality is difficult to hear. Arnold Schoenberg and his students Alban Berg and Anton Webern are regarded as the seminal atonal composers; the serialism of their later work is often distinguished from their earlier “free atonality.”

More narrowly still, the term is used to describe music that is neither tonal nor serial, especially the pre-twelve-tone music of the Second Viennese School, principally Alban Berg, Arnold Schoenberg, and Anton Webern.
Composers such as Alexander Scriabin, Béla Bartók, Paul Hindemith, Sergei Prokofiev, Igor Stravinsky, Edgard Varèse, however, have written music that has been described, in full or in part, as atonal.
While music without a tonal center had been written previously, for example Franz Liszt's Bagatelle sans tonalité of 1885, it is with the twentieth century that the term atonality began to be applied to pieces, particularly those written by Arnold Schoenberg and The Second Viennese School.
Their music arose from what was described as the crisis of tonality between the late nineteenth century and early twentieth century in classical music. This situation had come about historically through the increasing use over the course of the nineteenth century of
ambiguous chords, less probable harmonic inflections, and the more unusual melodic and rhythmic inflections possible within the style[s] of tonal music. The distinction between the exceptional and the normal became more and more blurred; and, as a result, there was a concomitant loosening of the syntactical bonds through which tones and harmonies had been related to one another. The connections between harmonies were uncertain even on the lowest—chord-to-chord—level. On higher levels, long-range harmonic relationships and implications became so tenuous that they hardly functioned at all. At best, the felt probabilities of the style system had become obscure; at worst, they were approaching a uniformity which provided few guides for either composition or listening. (Meyer 1967, 241)The first phase, known as "free atonality" or "free chromaticism", involved a conscious attempt to avoid traditional diatonic harmony. Works of this period include the opera Wozzeck (1917–1922) by Alban Berg and Pierrot Lunaire (1912) by Schoenberg.
The second phase, begun after World War I, was exemplified by attempts to create a systematic means of composing without tonality, most famously the method of composing with 12 tones or the twelve-tone technique. This period included Berg's Lulu and Lyric Suite, Schoenberg's Piano Concerto, his oratorio Die Jakobsleiter and numerous smaller pieces, as well as his last two string quartets. Schoenberg was the major innovator of the system, but his student, Anton Webern, is anecdotally claimed to have begun linking dynamics and tone color to the primary row, making rows not only of pitches but of other aspects of music as well (Du Noyer 2003, 272). However, actual analysis of Webern's twelve-tone works has so far failed to demonstrate the truth of this assertion. One analyst concluded, following a minute examination of the Piano Variations, op. 27, that
while the texture of this music may superficially resemble that of some serial music . . . its structure does not. None of the patterns within separate nonpitch characteristics makes audible (or even numerical) sense in itself. The point is that these characteristics are still playing their traditional role of differentiation. (Westergaard 1963, 109)Twelve-tone technique, combined with the parameterization of Olivier Messiaen, would be taken as the inspiration for serialism (du Noyer 2003, 272).
Atonality emerged as a pejorative term to condemn music in which chords were organized seemingly with no apparent coherence. In Nazi Germany, atonal music was attacked as "Bolshevik" and labeled as degenerate (Entartete Musik) along with other music produced by enemies of the Nazi regime. Many composers had their works banned by the regime, not to be played until after its collapse after World War II.
The Second Viennese School, and particularly 12-tone composition, was taken by avant-garde composers in the 1950s to be the foundation of the New Music, and led to serialism and other forms of musical innovation. Prominent post-World War II composers in this tradition are Pierre Boulez, Karlheinz Stockhausen, Luciano Berio, Krzysztof Penderecki, and Milton Babbitt. Many composers wrote atonal music after the war, even if before they had pursued other styles, including Elliott Carter and Witold Lutosławski. After Schoenberg's death, Igor Stravinsky began to write music with a mixture of serial and tonal elements (du Noyer 2003, 271). Iannis Xenakis generated pitch sets from mathematical formulae, and also saw the expansion of tonal possibilities as part a synthesis between the hierarchical principle and the theory of numbers, principles which have dominated music since at least the time of Parmenides (Xenakis 1971, 204).
The twelve tone technique was also preceded by "nondodecaphonic serial composition" used independently in the works of Alexander Scriabin, Igor Stravinsky, Béla Bartók, Carl Ruggles, and others (Perle 1977, 37). "Essentially, Schoenberg and Hauer systematized and defined for their own dodecaphonic purposes a pervasive technical feature of 'modern' musical practice, the ostinato" (Perle 1977, 37).
The term "atonality" itself has been controversial. Arnold Schoenberg, whose music is generally used to define the term, was vehemently opposed to it, arguing that "The word 'atonal' could only signify something entirely inconsistent with the nature of tone. . . . [T]o call any relation of tones atonal is just as farfetched as it would be to designate a relation of colors aspectral or acomplementary. There is no such antithesis" (Schoenberg 1978, 432). For some, the term continues to carry negative connotations.
"Atonal" developed a certain vagueness in meaning as a result of its use to describe a wide variety of compositional approaches that deviated from traditional chords and chord progressions. Attempts to solve these problems by using terms such as "pan-tonal," "non-tonal," "multi-tonal", "free-tonal," and "without tonal center" instead of "atonal" have not gained broad acceptance.
Setting out to compose atonal music may seem complicated because of both the vagueness and generality of the term. Additionally George Perle explains that, "the 'free' atonality that preceded dodecaphony precludes by definition the possibility of self-consistent, generally applicable compositional procedures" (Perle 1962, 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 (Seeger 1930).
Further, Perle 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" (Perle 1962, 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" (Perle 1962, 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" (Perle 1962, 9–10).
Composer Anton Webern held that "new laws asserted themselves that made it impossible to designate a piece as being in one key or another" (Webern 1963, 51). Composer Walter Piston, on the other hand, said that, out of long habit, whenever performers "play any little phrase they will hear it in some key—it may not be the right one, but the point is they will play it with a tonal sense. . . . [T]he more I feel I know Schoenberg's music the more I believe he thought that way himself. . . . And it isn't only the players; it's also the listeners. They will hear tonality in everything" (Westergaard 1968, 15).
Swiss conductor, composer, and musical philosopher Ernest Ansermet, a critic of atonal music, wrote extensively on this in the book Les fondements de la musique dans la conscience humaine (Ansermet 1961) where he argued that the classical musical language was a precondition for musical expression with its clear, harmonious structures. Ansermet argued that a tone system can only lead to a uniform perception of music if it is deduced from just a single interval. For Ansermet this interval is the fifth (Mosch 2004, 96). Modern atonal music, incomprehensible to Ansermet, chooses interval relations seemingly at random and cannot achieve such an impact, ethos, or catharsis for an audience.
