The Typotone, patented by Pinsonnat of Amiens on January 17, 1829, was approved for use by the Conservatoire de Musique, Paris, as a tuning device constructed to sound the pitch, A=441 vps. A freely vibrating reed, made of hallmarked gold, is attached to an opening in the center of a tiny, mother-of-pearl plate, about the size of a postage stamp. Deep grooves cut into the long sides of the mother-of-pearl plate enable a player to hold the device securely between the teeth. Merely breathing over the free reed sets it into vibration, freeing the player's hands to tune a violin or viola. The original, leather covered box also survives, with TYPOTONE stamped in gold across its red cover.
