"The main novelty is that it uses a longitudinal slot on the instrument’s tube instead of tone holes. The two sides of the slot are covered with a magnetic foil that attracts a magnetized ribbon on top. The ribbon is fixed on the upper end, stretched and lifted up from the lower end as a string on a violin. You can push down the ribbon anywhere, and it will seal up perfectly above it, so you can produce any note in the pitch continuum, resulting in a microtonal wind instrument. It can be played with eight fingers of the two hands or by sliding one finger up and down. The glissonic system can be used on various wind instruments: flute, recorder, clarinet, saxophone, tarogato, oboe, etc., or even the cornett."
