Clave (rhythm) The clave, (Spanish pronunciation: ['klaÎ²e],[1] Anglicized pronunciation: CLA(H)-vay), is a rhythmic pattern used as a tool for temporal organization in Afro-Cuban music.

The clavichord is a European stringed keyboard instrument known from the late Medieval, through the Renaissance, Baroque and Classical eras. Historically, it was mostly used as a practice instrument and as an aid to composition, not being loud enough for larger performances. The clavichord produces sound by striking brass or iron strings with small metal blades called tangents. Vibrations are transmitted through the bridge(s) to the soundboard.
