The organflute ("florgan"), a newly invented musical instrument
(invented, designed, built, and played by by S. Mann),
combines the user-interface of the flute (played by blocking finger holes)
with the sound of the pipe organ:
Another instrument, the plasmaphone, invented by S. Mann, produces
sound acoustically, by matter in its fourth state (plasma).
It can produce percussion sounds as well as steady non-decaying tones.
This version of the plasmaphone makes sound underwater, by way of
a plasma-probe inserted into water. This video demonstrates percussion
(short bursts of less-definite pitch).
