Professor Kofi Agawu of Princeton University provides the third in The Essay series running in parallel to the BBC TV series Civilisations. Once again he is responding to the question of whether or not music is an entirely civilising force, and he does so having just returned from a visit to west Africa. Prof Agawu wonders how the musicians of the Asante kingdom, the sophisticated drummers, poets and singers, might respond to the idea that what they do is civilising, but he also tackles the colonial notion that the music of the colonisers was somehow superior to indigenous music and with that civilising. It's not a theory that stands the test of time when he recalls the four-part Lutheran hymns he remembers from his youth with the highly sophisticated rhythmic and poetic structures of Asante music which are now used in serious and popular music around the world.
