Son clave is a two-bar framework pattern built from asymmetric 3-2 or 2-3 hit groupings

Son clave is one of the most important rhythmic foundations in Cuban and Latin American music. It is a two-bar pattern that divides hits asymmetrically: the 3-2 version places three hits in the first bar and two in the second; the 2-3 version reverses this order. The pattern gets its name from the claves instrument typically used to express it, though the rhythm can appear on any instrument — kick, snare, synth phrase, or melody. The asymmetry creates syncopation, giving the clave its characteristic ‘liveliness’. The 3-2 version is more relaxed; the 2-3 feels more modern and is common in African-American music.

Examples

3-2 Son Clave: x..x..x. | ..x.x... (3 hits bar 1, 2 hits bar 2). 2-3 Son Clave reverses: ..x.x... | x..x..x. In Strudel: s("cp(3,8)") approximates the first bar feel.

Assessment

Given a drum pattern, identify whether it uses 3-2 or 2-3 son clave. Explain what ‘syncopation’ means in this context and why clave is described as a ‘framework’ rather than just a rhythm.
