What is a Tresillo?

Tresillo is a rhythmic pattern consisting of three evenly spaced notes that create a distinctive syncopated rhythm within a measure. It is one of the most fundamental rhythmic figures in Afro-Cuban and Latin music traditions and has influenced many modern musical styles.

In its most common form, the tresillo pattern divides a measure of 4/4 time into three accented notes spaced unevenly across eight subdivisions. The pattern typically follows a 3-3-2 grouping, meaning the first note occurs, then another three subdivisions later, another three subdivisions later, and finally a two-subdivision gap completes the measure. This creates a syncopated rhythm that feels both steady and off-center.

Tresillo originated in African rhythmic traditions and became a central element of Cuban music, including styles such as son, rumba, and mambo. The pattern later spread into jazz, pop, hip-hop, and electronic music, where it often appears in drum patterns, basslines, and rhythmic accents that give a groove its distinctive forward-moving feel.
