An adjustable pitch musical drum is provided which includes a tubular cylindrical casing having its axis vertical, and a conventional drum head in tension over another end of the casing. A plurality of legs support the casing off the floor and a foot pedal is provided below the casing for adjusting the tension in the drum head. A tensioning mechanism connects the pedal to the drum head so that a relatively large movement of the pedal results in a small tensioning movement at the drum head to vary the frequency and hence the pitch of the note produced by the drum.
