The Khol is a classic percussion from Bangladesh, from the same family as the Indian percussions Dholak, Mridangam or even the Pakhâwaj. Made of terracotta (therefore a little fragile), it offers a powerful sound, allows many effects, in particular the glissando (same as on the Bayan). The Khol also accompanies Bhajan and Kirtan religious songs, and it is also played by the Bâuls (a sort of troubadour, poet).
