CONCEPT DIGEST: ### The Distinctive Musical Elements of 20th Century Music The composers came up with new rhythms and meters. Some of these are the use of the following: - **Polyrhythm:** is the simultaneous sounding of contrasting layers of rhythmic patterns. - **Unusual meters:** occurs when the composer uses the 5, 7, 11 or other uncommon metric groupings. - **Multimeter:** occurs when changes in meter happen within a composition. - **Syncopation:** occurs when the accents are placed on the supposedly weak beats. The use of whole-tone scale, pentatonic scale, and twelve-tone system is evident and creates the distinctive sounds of the melodies. - **Whole-tone scale:** a scale having whole intervals. - **Pentatonic scale:** consists of five tones. - **Twelve-tone system:** uses the 12 chromatic tones. Vast use of dynamics, unusual instrumental combinations and effects is evident and these are innovations made in terms of the timbre-dynamic element. ### Polyphonic texture intensified. - Polyphony is the simultaneous sounding of two or more melodies.
