Like the list of teachers, this list of camps and workshops that are overtly concertina- and accordion-friendly isn’t complete. We’ll update it periodically, but try doing your own research, too–you might be surprised at what you find in your own back yard.
Concertinas and accordions are the raison d’être of the Northeast Squeeze-In, a weekend event in the Berkshires featuring workshops, sessions, and lots of friendly free-reed enthusiasts. Other instruments are welcome, so it’s safe to bring friends and family who play strings, winds, and so forth. It’s held in late September, generally a beautiful time of year in New England. Even non-musical companions will enjoy tagging along.
