Afro-Cuban music can be divided into religious and profane. Religious music includes the chants, rhythms and instruments used in rituals of the religious currents mentioned above. Profane music includes rumba, guaguancó, comparsa (carnival music) and lesser styles such as the tumba francesa. Virtually all Cuban music is influenced by African rhythms. Cuban popular music, and much of the art music, combines influences from Spain and Africa in ways unique to Cuba. For example "son" combines African instruments and playing styles with the meter and rhythm of Spanish poetic forms. While much of the music is performed in cut-time, artists typically use an array of time signatures like 6/8 for drumming beats. On the other hand, clave uses a polymetric 7/8 + 5/8 time signature.
