Blowdrum (2002)

This drum has a black leather head. Its body was a water tank. A pipe runs from the bottom of the tank to a breathing tube. Since the drum is airtight, blowing into the tube effectively tightens the head and raises its pitch. The black leather head produces a dull sound and, depending on the tightness of the head, a low register sweep of around a fifth is obtainable from it.
