Whats the difference between a concertina and an accordion?
In their simplest form, a concertina (a 6 or 8 sided instrument) and an accordion work on a similar principle: air blown across reeds as valves are opened by depressing a note. The bellows produce this air as they are pulled apart or pushed together. The common scale is played in the same way as a mouth organ, that is, blow, suck (push/pull), blow, suck, blow, suck, suck, blow. They were developed from around 1830 and gradually vast improvements were made to accommodate more skillful players – some requiring virtuoso ability.
