Accordion
Josh Middleton
The accordion is used all the time in klezmer these days, as it can cover many (all?!) roles. There is one accordion player of note in the annals of North American klezmer history - Mishka Ziganoff, who was probably the most-recorded accordion player on the klezmer scene.
The accordion can be seen and heard as very much a part of Argentinian klezmer bands in the 1950s.
The accordion was sometimes known as harmoshke.
