Daxophone tongues. "Rarely does an instrument’s form match up with it’s sound as perfectly and whimsically as the daxophone’s. Invented by Hans Reichel of Germany, the daxophone is a friction idiophone who’s vibrating mechanism is an oddly but tactically shaped wooden tongue which is attached to a block of wood. The vibrations travel from the vibrating blade to the block where a contact microphone amplifies the sound. The whole concept is similar to plucking a ruler half-way off a table."
