Aye, I am also a 24-hole stressed harmonica, a beginner and self-taught. I think red river valley, Moon River, Farewell, Irish Thrushcross, Always with me and In fact, you don't understand my heart are all suitable for novices (but I only play a single note without skill). I'll give you some music scores, because some of my songs are played against the guitar books, and there is no special piano score!
