Features the riity, the one string Senegalese fiddle that I bought when I was there. It's got a raspy sound and plays the main riff from the beginning of the song. The riity uses a horsehair string (a bundle of horsehair) and is played with a horsehair bow. A very simple little tune, rather humble but funky. "Ndank Ndank" means 'Little by Little' in Woloff.
