20th-century classical music describes art music that was written nominally from 1901 to 2000, inclusive. Musical style diverged during the 20th century as it never had previously. So this century was without a dominant style.

post-romanticism can all be traced to the decades before the turn of the 20th century, but can be included because they evolved beyond the musical boundaries of the 19th-century styles that were part of the earlier

expressionism came mostly after 1900.
Minimalism started much later in the century and can be seen as a change from the modern to post-modern era, although some date post-modernism from as early as about 1930.

Maurice Ravel's music, also often labelled as impressionist, explores music in many styles not always related to it (see the discussion on Neoclassicism, below).

Many composers reacted to the Post-Romantic and Impressionist styles and moved in quite different directions. The single most important moment in defining the course of music throughout the century was the widespread break with traditional tonality, effected in diverse ways by different composers in the first decade of the century. From this sprang an unprecedented "linguistic plurality" of styles, techniques, and expression. In

Post-romanticism. In the 20th century, the different styles that emerged from the music of the previous century influenced composers to follow new trends, sometimes as a reaction to that music, sometimes as an extension of it, and both trends co-existed well into the 20th century. The former trends, such as
Expressionism are discussed later.
In the early part of the 20th century, many composers wrote music which was an extension of 19th-century Romantic music, and traditional instrumental groupings such as the

Romantic music.) Some writers hold that Schoenberg's work is squarely within the late-Romantic tradition of Wagner and Brahms and, more generally, that "the composer who most directly and completely connects late Wagner and the 20th century is Arnold Schoenberg".
Neoclassicism
Neoclassicism was a style cultivated between the two world wars, which sought to revive the balanced forms and clearly perceptible thematic processes of the 17th and 18th centuries, in a repudiation of what were seen as exaggerated gestures and formlessness of late Romanticism. Because these composers generally replaced the functional tonality of their models with extended tonality, modality, or atonality, the term is often taken to imply parody or distortion of the Baroque or Classical style.

Prokofiev's ''

Stravinsky's ''

Postmodern music
Postmodernism is a reaction to modernism, but it can also be viewed as a response to a deep-seated shift in societal attitude. According to this latter view, postmodernism began when historic (as opposed to personal) optimism turned to pessimism, at the latest by 1930.
John Cage is a prominent figure in 20th-century music, claimed with some justice both for modernism and postmodernism because the complex intersections between modernism and postmodernism are not reducible to simple schemata. His influence steadily grew during his lifetime. He often uses elements of chance:
Imaginary Landscape No. 4 for 12 radio receivers, and
Music of Changes for piano.
Sonatas and Interludes
''Sonatas and Interludes'' is a cycle of twenty pieces for prepared piano by American avant-garde composer John Cage (1912–1992). It was composed in 1946–48, shortly after Cage's introduction to Indian philosophy and the teachings of art hist ...

prepared piano: a normal piano whose timbre is dramatically altered by carefully placing various objects inside the piano in contact with the strings. Currently, postmodernism includes composers who react against the

minimalism, in which the work is stripped down to its most fundamental features; the music often features repetition and iteration. An early example is Terry Riley's ''
In C'' (1964), an

Piano Phase
''Piano Phase'' is a minimalist composition by American composer Steve Reich, written in 1967 for two pianos (or piano and tape). It is one of his first attempts at applying his "phasing" technique, which he had previously used in the tape pieces ...
'' (1967, for two pianos), and
''Drumming'' (1970–71, for percussion, female voices and piccolo) employ the technique called
phasing in which a phrase played by one player maintaining a constant pace is played simultaneously by another but at a slightly quicker pace. This causes the players to go "out of phase" with each other and the performance may continue until they come back in phase. According to Reich, “''Drumming'' is the final expansion and refinement of the phasing process, as well as the first use of four new techniques: (1) the process of gradually substituting beats for rests (or rests for beats); (2) the gradual changing of timbre while rhythm and pitch remain constant; (3) the simultaneous combination of instruments of different timbre; and (4) the use of the human voice to become part of the musical ensemble by imitating the exact sound of the instruments”. ''Drumming'' was Reich’s final use of the phasing technique.
Philip Glass's ''1 + 1'' (1968) employs the additive process in which short phrases are slowly expanded. La Monte Young's ''Compositions 1960'' employs very long tones, exceptionally high volumes and extra-musical techniques such as "draw a straight line and follow it" or "build a fire".
Michael Nyman argues that minimalism was a reaction to and made possible by both serialism and indeterminism. (See also

Atonality and twelve-tone technique
Arnold Schoenberg
Arnold Schoenberg or Schönberg (, ; ; 13 September 187413 July 1951) was an Austrian-American composer, music theorist, teacher, writer, and painter. He is widely considered one of the most influential composers of the 20th century. He was as ...
is one of the most significant figures in 20th-century music. While his early works were in a late Romantic style influenced by Wagner (''
Verklärte Nacht'', 1899), this evolved into an atonal idiom in the years before the First World War (''
Drei Klavierstücke'' in 1909 and ''
Pierrot lunaire'' in 1912). In 1921, after several years of research, he developed the
twelve-tone technique of composition, which he first described privately to his associates in 1923. His first large-scale work entirely composed using this technique was the
Wind Quintet, Op. 26, written in 1923–24. Later examples include the
Variations for Orchestra, Op. 31 (1926–28), the Third and Fourth
String Quartets (1927 and 1936, respectively), the
Violin Concerto

and these three composers are often referred to as the principal members of the
Second Viennese School (Haydn, Mozart and Beethoven—and sometimes Schubert—being regarded as the
First Viennese School in this context). Webern wrote works using a rigorous twelve-tone method and influenced the development of
total serialism. Berg, like Schoenberg, employed twelve-tone technique within a late-romantic or
post-romantic style (

in this decade provided composers with a medium which allowed recording sounds and then manipulating them in various ways. All electronic music depends on transmission via loudspeakers, but there are two broad types:
acousmatic music, which exists only in recorded form meant for loudspeaker listening, and live electronic music, in which electronic apparatus are used to generate, transform, or trigger sounds during performance by musicians using voices, traditional instruments, electro-acoustic instruments, or other devices. Beginning in 1957, computers became increasingly important in this field. When the source material was acoustical sounds from the everyday world, the term
