This fiddle tune played by Bluegrass and Irish players, and is on my CD "Black Mountain Harmonica". The tune is in the key of G, so you will need a G harmonica in first position.
The tune has an AABB structure, as follows:
7B 7D 6D 6B 5B 4B 4D 5B 4D 4B 3D" 2D
4B 4B 4B 4D 5B 5D 6B 5B
7B 7D 6D 6B 5B 4B 4D 5B 4D 4B 3D" 4B
3D 4D 3B 3D" 3D 4B
repeat
6B 5D 5B 6B 6D 7D 7B 6B 5B
6B 5D 5B 6B 6D 7D 7B 7D
7B 7D 6D 6B 5B 4B 4D 5B 4D 4B 3D" 4B
3D 4D 3B 3D" 3D 4B
repeat
