Microtonality

Definition

Microtonality refers to the use of intervals smaller than the conventional semitone in music, allowing for the exploration of pitches and scales that deviate from the standard Western tuning system. This concept has significant implications in 20th century American classical music, as composers began to push the boundaries of traditional harmonic structures, creating new soundscapes that incorporated these smaller intervals. The exploration of microtonality led to innovative approaches to melody, harmony, and texture, influencing various musical styles and practices.
