Illustration from the French patent belonging to the manufacturer Couesnon (1924).
The couesnophone, also known as the goofus or queenophone, is a free-reedmusical instrument resembling a saxophone. Its reeds vibrate when the desired keys are activated and the player blows through a tube. Frenchmanufacturer Couesnon was awarded the patent no. 569294 in 1924 for an instrument that was described as a saxophone jouet (fr. "toy saxophone"). However, the couesnophone is a polyphonic instrument, while the saxophone is monophonic.
The couesnophone may be held like a saxophone or like a melodica (horizontally), given that the mouthpiece consists of a rubber tube that allows both positions. The keys are set in a layout similar to that of the Hohner early (proper – see ) melodicas, i.e. in two parallel rows: one corresponds to the white keys of a pianokeyboard, while the other comprises the black keys.
