OctobanOctobans are one of TAMA's first original instruments and have been used by a diverse group of progressive players including Billy Cobham, Simon Phillips, Stewart Copeland, Bill Bruford, Mike Portnoy, and Tim Alexander. Instead of relying on changing drum diameters, the pitch of each Octoban differs according the length of the drum's shell. The 6" diameter shells can be tuned melodically and are available in low-and high-pitch sets.

Octobans, also known as tube toms, are deep, small diameter, single-head tom-toms. Octobans were originally grouped in melodically-tuned sets of eight, hence the name, in reference to octave and from octo meaning "eight".

Complete and half sets of octobans are commonly mounted in clusters of four, in a square pattern. Mounts for four drums in a straight line, dual mounts for two drums, and individual mounts are all also reasonably common.
