Continuous Pitch Wind Instruments

Glissonic tarogato or glissotar 1.0

What makes the Glissonic Wind Instruments different?

Blow on a wind, play on a string!

Glissonic is a completely new wind instrument family. The main novelty is that instead of tone holes it uses a longitudinal gap or slot on the tube of the instrument. The two sides of the slot are covered with magnetic foil which attract 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, it will seal up perfectly above it, so you can produce any note in the pitch continuum. 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 all kind of wind instruments: flute, whistle, clarinet, saxophone, oboe etc. or even the cornett, which is a brass instrument made out of wood.

Dániel Váczi

Dániel Váczi is a saxophone player, composer, inventor and researcher of musical instruments and games.
Born in 1972, Budapest.
He graduated from the ELTE as a biologist in 1998. He studied at the Jazz Saxophone Faculty of the LFZE in 1999 for one year.
He founded his jazz trio in 2001. It became a quintet called Multet in 2009. He is also a member of other bands: Trio Squelini - often with Ditta Rohmann cellist as a guest (world-jazz), Kada ad Libitum (free improvisation), Ektár (world-jazz) and Budapest Improvisers Orchestra (contemporary classical mixed free improvisation). His discography contains about 30 CD.
He developed a “Reticular Music System” which is both a music theoretical approach on the one hand, and a technique for composing and improvising on the other.
With the collaboration of László Fassang and others he made a concert (Etudes for player organ) at MüPa Budapest in 2014 that researched the augmented possibilities of the organ with computerized MIDI control. This work was continued in 2015 (Organmatrix), and extended to dance, animation, and intermedia. His application called SoundEmbroidery - a sound-visualisation tool based on the new and original principle of PitchCompass, programmed and designed by XORXOR - was created and developed for this occasion. He also uses the MIDI controlled acoustic piano player of BMC.
He has engaged in building various music-automatons, and participated in the development of the gigantic music box “Hangjáték” made by Medence Csoport for MüPa as an adviser and composer in 2015. Along with two partners, he produces and distributes programmable mechanical music box called Skatuya.
Among his many music instrument-inventions the glissando-woodwinds - glissonic flute, recorder, tárogató, saxophone, chalumeau (clarinet), oboe - are in their final stage of development. He has plans for a new symmetric - dihexatone - keyboard too.
He has also invented a new game of logic called Urobo. It is based on the circular hierarchy of the 12 music notes.
With his wife, Nóra Jakobi (psychologist, music therapist), and others he has participated in several workshops for children at ÉlményMűhely (Workshop of Experiences) in the field of experience-oriented mathematics focusing on play (Urobo) and its musical aspects (Skatuya) in 2014 and 2015.
