The rumba clave is a rhythmic pattern used in Afro-Cuban music, particularly in styles like rumba and salsa. It consists of a five-note sequence that creates a syncopated feel, typically played on a pair of wooden sticks called claves. The pattern is essential for establishing the groove and guiding musicians in ensemble performances. In the rumba clave, the two main variations are the 3-2 and 2-3 patterns. The 3-2 pattern emphasizes the first three beats, while the 2-3 pattern highlights the last three beats. This rhythmic foundation is crucial for dancers and musicians, as it influences the overall structure and energy of the music.
