The Daxophon by Hans Reichel
Who does not remember to have made a ruler made sound by plucking at the edge of the table as a child. The German guitarist, improviser, composer and instrument inventor Hans Reichel (1949-2011) from Wuppertal has brought this simple principle to a professional level.
A 30 cm long wooden tongue is played with a cello bow. In a resonance box, the sound is picked up by contact microphones. The Daxophon Is an idiophone and at the same time a string instrument.
The Dax takes a decisive function. This is a handy, round shaped block with which the pitch is varied. On one side the block has frets so that sound sequences can be played, while the smooth side allows flowing glissandi.
What particularly fascinates me is the voice-like sound that the Daxophon produces. This comes through vocal-like formants, which arise when the Dax blocks the oscillation in the wood tongue at the contact points.
It can only say yes, no no.
