KEEP AWAY !!!! from the written music....

He "knows" ( or should quickly learn a 3rd and 5th)

A suggestion: Tune the fiddle the night before.....leave it outside the room....in the morn they should arise...with at least four notes on their brain (tune in the radio to wakeup...it need be).......go to the fiddle each morn...and try to emulate the tune from their waking...and then drop it a third and then again a fifth....

Sixty days MAX....and of harmony they will have no doubt....(they may also lack a spouse.)
