Emancipation of the dissonance

The emancipation of the dissonance was a concept or goal put forth by composer Arnold Schoenberg and others, including his pupil Anton Webern, who styled it The Path to the New Music.

By the later nineteenth century the higher numbered dominant-quality dissonances had also achieved harmonic status, with resolution delayed or omitted completely.

The greater autonomy of the dominant-quality dissonance contributed significantly to the weakening of traditional tonal function within a purely diatonic context.

Michael Broyles calls Ives' tone-cluster-rich song "Majority" as "an incantation, a mystical statement of belief in the masses or the people".

[citation needed] The musicologist Jacques Chailley,[7] cited by Jean-Jacques Nattiez,[8] gives the following diagram, a specific timeline he proposes: A 1996 book by Thomas J. Harrison, 1910, the Emancipation of Dissonance, uses Schoenberg's "revolution" to trace other movements in the arts around that time.

Chords, featuring chromatically altered sevenths and ninths and progressing unconventionally, explored by Debussy in a "celebrated conversation at the piano with his teacher Ernest Guiraud " (Lockspeiser 1962, 207).
