Glissonic Instruments

Glissotar is the first member of the Glissonic family. The main novelty is that instead of tone holes it uses a longitudinal slot on the tube of the instrument, covered with a stretched ribbon. You can push down the ribbon anywhere, it will seal up perfectly above it, so you can produce any note in the pitch continuum. It is based on the Hungarian tarogato, which is a single-reed instrument with a conical wooden body. It can be used with a soprano saxophone mouthpiece and it has two octave keys for the upper register.
