Good day,
I am from South Africa, and play with a 40 key concertina.
as someone refer to the Boer style...yes that is definitely true...we play on all 12 keys....like you get on a piano...
it is not very easy, but i can make it easy for you guys...if someone is interested i have complete lessons i can share with you....included some clips explaining to you how the song sounds like and to play the correct accents....
