Uncle Jaque:

alas, I too am a concertina, although I play a Wheatstone, chromatic concertina. I mostly play Irish music with it, do a little bit of chording, but I know people who do chord alot, and it works quite well. I am fortunate in that my instrument was handed down in my family (I can trace it's ownership back to 1906). I have had it retuned my Frank Edgley in Ontario, but I know that there are people in the eastern states who do the same. There is another link for a great concertina page at the home of Don Nichol's. Lots of information there....

Enjoy, they are a great instrument.....
