I play a few instruments and have just started learning harmonica. There are some good online tutorials on youtube, and now that people have their own channels, it's easy to go through the 3-4 minute "lessons" in the right order.
I bought a Hohner Special 20 in C, which I think is a good one to start with (in case it gets put in a drawer!)
BTW this is my first post on this forum....
Have been enjoying browsing all the songbooks on here. It's a brilliant site!
