Self-playing ConcertinaAlso known as Tanzbaer / Player Concertina / Automatic Concertina / Automatic Bandoneon.
The self-playing mechanical Concertina plays with real reeds, like a real instrument. Therefore the tone generation is absolutely mechanical - without a speaker/amplifier. You only have to move the bellows to produce the air for the reeds. The finger movements are taken over by an electronic control system and the songs are saved on a small memory card.
Tone scale: 20 tone
