A Short History of Five Notes
Last updated: 25 february, 2011 - 14:36 GMT
The five notes go by many names in different countries and although their origins lie in West Africa, they have travelled back and forth across the Atlantic. In most cases they form a powerful underlying rhythm which is repeated throughout a song during a performance: a group of three beats, answered by another two beats, followed by three beats, answered by two beats, and so on.
On this map, you can explore a few of the places and musical styles mentioned in the documentary which draw their strength from the five notes.
