Harmonica: Ain't No Sunshine ( When She's Gone ). Video Diary 19.
I have been playing for 2 and a half years now. I am keeping a video diary to help me keep a track of my progress as I learn the harp.
The two harmonica teachers on Youtube that has helped me to understand the harmonica are Liam Ward and Tomlin Leckie. They both have fantastic tutorial videos for beginners and beyond. If you are just starting out learning the harmonica, I would suggest looking at the above two harmonica teachers.
