An unusual instrument, it consists of a mouthpiece section, with 12 transverse
tonetubes, each with one fingerhole. The instrument produces a thin, sharp tone
with surprising power, despite of the fragile instrument.
The instrument makes no sound until at least one fingerhole is covered, as the open fingerhole inhibits the tone. It requires quite some air as all tubes recieve air, even if not in use.
How it works:
The air passes trought the horizontal tube, get broken over a sharp edge, and sets the air in the vertical tube in vibration. Opening the fingerhole (H) causes the svinging to collapse, as the open fingerhole tries to establish a nodal point out of tune with the tube itself. the tone of the tube is tuned with the always open hole (t). In this example only one vertical tube is shown.
