I already play several instruments, including OK guitar and OK banjo (not great at all). A couple of years ago I got interested in the Cajun accordion. I ultimately purchased a C and a D. Played Cajun accordion as taught by the Savoy family at Fiddle Tunes here in the Seattle area, (Port Townsend), and later by Blake Miller with Cedric Watson.

So I play a few Cajun tunes now, and also sing in French (need to read the lyrics so far). But there is minimal opportunity for playing in a Cajun setting here, so I go to a weekly old time fiddle jam, where most of the tunes are bluegrass, Appalachian, some Tin Pan Alley tunes etc. I also go to a roots jam where it is mostly county blues.

Almost all of these tunes, I can accompany on either the C or the D accordion. Its fun, and for the most part, is received OK. Seems like you can accompany in quite a few keys adequately on the C and D boxes combined.
