The name given to the repeating accompaniment patterns played by Latin jazz pianists is:
a. Tumbao
Tumbao is a rhythmic pattern typically played on the bass or piano in Latin music genres such as salsa, mambo, and Latin jazz. It provides the foundational groove and helps drive the music forward. The tumbao pattern is characterized by its syncopated feel and is essential for creating the distinctive rhythmic texture of Latin jazz music.
In Latin jazz, pianists often incorporate tumbao patterns into their playing to add a rhythmic and harmonic richness to the music. These patterns can vary in complexity and style but generally serve to enhance the overall groove and energy of the music. Mastering tumbao patterns is crucial for musicians looking to authentically play Latin jazz and other Latin music styles.
