I'm playing my iPod!
I've played English concertina for years, so when I got my iPod Touch, this was the first app I bought! And it's wonderful! I was a little frustrated at first until I got the "feel" of it and learned to hit the buttons accurately, but that happens amazingly fast. Same with relating to a 2-dimensional instrument instead of a three. Much of the time it seems like learning a new instrument, but sometimes I can close my eyes and pretend I'm playing my real one and the tune comes naturally. In two days, I am able to play a number of tunes, and I'm really enjoying the practice. The tone is wonderful, I think better than my Wheatstone. Stephen Foster tunes sound great, and jigs and reels are easy to play. I'm not listening to my iPod, I'm playing it!
