I just recently got my concertina and I have been working on it a lot. I have been finding music online from here or elsewhere, and one thing confuses me. My concertina is a c/g and when I am playing in g I have to make sure the song doesn't have any low e's because it can't play those, it skips over them. Is there a good way to get over that or a better way to change the key than note by note? Thanks in advance...

Hello, I'm interested in getting a concertina to learn to play and use in conjunction with a clown character I am developing. I want it to be functional and be able to play different types of music, but I would also like to have it be something easier so I can dance and jump around whilst playing. I've been looking at 20 button anglo's so far. Let me know if you have any ideas of a better concertina or something else. Thanks
