The Dreaded Bodhran Solo.

The band stops... you can hear your drum louder that ever. Love them or dread them, the bodhran solo is here to stay.

This is the part usually in a live performance when the bodhran player spends a few minutes playing on their own. It usually involves demonstrating great skill and ability and although it may appear improvised, most actually follow a scripted path that will demonstrate the skill and ability of the player.
