Clave (rhythm)The clave (ˈklɑːveɪ,_kleɪv; ˈklaβe) is a rhythmic pattern used as a tool for temporal organization in Cuban music. In Spanish, clave literally means key, clef, code, or keystone. It is present in a variety of genres such as Abakuá music, rumba, conga, son, mambo, salsa, songo, timba and Afro-Cuban jazz. The five-stroke clave pattern represents the structural core of many Cuban rhythms. The clave pattern originated in sub-Saharan African music traditions, where it serves essentially the same function as it does in Cuba.
PolyrhythmPolyrhythm is the simultaneous use of two or more rhythms that are not readily perceived as deriving from one another, or as simple manifestations of the same meter. The rhythmic layers may be the basis of an entire piece of music (cross-rhythm), or a momentary section. Polyrhythms can be distinguished from irrational rhythms, which can occur within the context of a single part; polyrhythms require at least two rhythms to be played concurrently, one of which is typically an irrational rhythm.
