Compound Operations in Basic Atonal Theory by John Rahn



What is atonal theory?

In atonal theory, we assign integers (whole numbers) the task of representing pitches. Integers are powerful representatives of pitch because of their ability to be equally spaced (like their chromatic letter-name counterparts) and their ability to be ordered.

How do you Analyse atonal music?

The first step to any analysis of atonal music should be to identify the pitch sets by identifying chords, melodic figures, or motives that are important. This process is known as segmentation. segmentation — the process of identifying and labeling the pitch sets in a composition.

What is an example of atonal?





In practice, the atonality of a composition is relative, for an atonal work may contain fragmentary passages in which tonal centres seem to exist. Schoenberg’s song cycle Pierrot Lunaire (1912) and Alban Berg’s opera Wozzeck (1925) are typical examples of atonal works.

What is atonal used for?

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.

What is atonal music based on?

All atonal music is music that is written without a tonal center or key; however, it is still a system that is based around the same set of notes found in tonal music and the western chromatic scale. A chromatic scale is a scale that includes all 12 possible pitches in Western music.

Who is the father of atonal music?





Arnold Schoenberg

Who was Arnold Schoenberg? Arnold Schoenberg was an Austrian-American composer who created new methods of musical composition involving atonality, namely serialism and the 12-tone row. He was also an influential teacher; among his most significant pupils were Alban Berg and Anton Webern.

What is the style of atonal?

Atonal music, which began to emerge in the early twentieth century, features music that does not have a tonal center.

What is the meaning of atonality?

: marked by avoidance of traditional musical tonality. especially : organized without reference to key or tonal center and using the tones of the chromatic scale impartially.

What is tonal vs atonal?



Atonality is simply the absence of tonality, tonality being the musical system based on major and minor keys. Now it’s true that atonal music often includes lots of harsh dissonance… but so too does tonal music, the music of Bach, Mozart, and Beethoven.

What does tonal and atonal mean?

Tonal: Term used to refer to notes or chords that are part of a given tonality. Atonal: Means that the note or chord in question does not belong to the tonality. For example, the F# note is atonal to the key of C major.

How do you know if something is atonal?

3 Characteristics of Atonal Music

  • No tonal center: Atonal music does not exist in a major key or a minor key.
  • Based around the chromatic scale: In Western music, the chromatic scale is a 12-note scale that involves all available pitches played in order.

What is the atonal scale?

All atonal music is music that is written without a tonal center or key; however, it is still a system that is based around the same set of notes found in tonal music and the western chromatic scale. A chromatic scale is a scale that includes all 12 possible pitches in Western music.

Does atonal music have rhythm?



In contrast, atonal pieces (D–F) show different time signatures and a large variety of note lengths, resulting in a complex rhythm without a regular meter. Tonality in the classical pieces is indicated by the set-up of the home key in the beginning.
