Polychords are harmonic structures that consist of two or more chords played simultaneously, creating a rich and complex sound. This concept often appears in modern music styles, especially during periods of expressionism and atonality, where traditional tonal frameworks are challenged. By stacking chords, composers can evoke varied emotional responses and explore new musical territories.
congrats on reading the definition of polychords. now let's actually learn it.
Polychords were notably used by composers like Charles Ives and Igor Stravinsky, who explored innovative harmonic techniques in their works.

This layered sound allows composers to push boundaries and explore deeper emotional narratives within their compositions.
Discuss the relationship between polychords and atonality in 20th-century music.
Polychords are closely related to atonality as they challenge traditional tonal structures by layering multiple chords that may not adhere to a singular key center. This approach aligns with atonal music's focus on dissonance and the rejection of tonal hierarchies. Composers experimenting with polychords often move beyond conventional harmonic progressions, leading to an exploration of new sonic possibilities that define much of 20th-century music.
