(ah bah kwa) is a rhythm and dance from a men's secret society in Cuba. The music, based in 6 feel, has strong elements of cross and polyrhythm, which add to its mysterious nature. Traditional instrumentation consists of three small single headed drums held on the shoulder and played with one hand, two basket rattles, a bell and one lead drum called bonko (bong koh) which is the size of a small ashiko. It is held vertically and played with two hands in the same manner as a conga. Aba Cua has strong ties to Rumba Columbia and is sung in an African tongue from a region of Southwest Nigeria.
