What is the difference between a Chemnitzer Concertina and a Bandoneon?
The most significant difference is the keyboard layout, which has some similar notes at the core, but varies significantly around the edges. Most bandoneons are double-reed, octave-tuned with one middle and one high reed per note. Also, the decorative style of a bandoneon is usually more subdued, while chemnitzers often tend toward flashiness.
