This is a great and fun to play instrument. I will give you simple instructions to follow so that you too can build your own unique instrument. On mine, there are 3 octaves, plus an extra C. If you plan everything right, it can be easy to build. Special thanks to Snubby J who first inspired me to build one. I used ABS pipe even though I called it a PVC instrument.
