My 4-year-old son just got a standard 10 hole harmonica in C from his grandmother, and I would like to give him a good start that will encourage him to enjoy playing.
I myself started out just like this, and I own a 10 hole chromatic harmonca which I play occasionally. I am nowhere near professional skill, but I can play some simple tunes. I also have a couple blues harmonicas I have played around with.
I would like to get some tips on what to do to encourage my son to play, and how to teach him at so young an age, without taking away the fun for a 4 year old. He likes music, and sings a lot.
