STAMPING TUBES
Stamping tubes are tubes of varying lengths, stopped at one end, sounded by stamping the closed end on the ground. There’s some idiophonic percussion sound, but the main tone comes from the resonance of the enclosed air activated by the jolt of the hit. Stamping tubes have a history in many parts of the world, especially places with lots of bamboo. Large tubes with low tones sound particularly great. It’s hard for one person to play more than one or two tubes, but stamping tubes work nicely for groups of players each playing a couple of them in hocketing fashion. The tuned set shown here is made of plastic drain pipe with heavy end caps.
In the audio clip, several stamping tubes are accompanied by a bit of percussion.
