Just as the harmonic series was and is used as a justification for consonance, such as by Rameau, among others, the harmonic series is often used as physical
or psychoacoustic justification for the gradual emancipation of intervals and chords found further and further up the harmonic series over time, such as is argued by Henry Cowell in defense of his tone clusters.
The musicologist Jim Samson describes: As the ear becomes acclimatized to a sonority within a particular context, the sonority will gradually become ’emancipated’ from that
context and seek a new one.
 Rudhyar gave the subtitle “A New Principle of Musical and Social Organization” to his book Dissonant Harmony, writing, “Dissonant music is thus the music of true and spiritual
Democracy; the music of universal brotherhoods; music of Free Souls, not of personalities.
 The musicologist Jacques Chailley, cited by Jean-Jacques Nattiez, 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.
Michael Broyles calls Ives’ tone-cluster-rich song “Majority” as “an incantation, a mystical statement of belief in the masses or the people”.
We are something apart, yet an integral part”.
