Limon.
Thank you very much for the compliment!
I am sorry I do not have music or TAB written out for the harmonica riff.
It was just something I made up on the spot to show the sound off.
The harp riff was all around the 5th to the 7th fret in a standard blues scale.
I used a lot of two note chords playing intervals of a third.
Its pretty easy to play, I am sure if you use your ear you will find the notes.
Thanks again and have fun!
Bill
