Bill Monroe recorded the song “On and On,” which has become a bluegrass standard, in the key of A, so that’s where you’ll learn it, using the L shapes, arpeggios, and double stops you’ve used for the keys of G and D. It is, of course, common to play solos in open position in the key of A, but it’s good to know the up-the-neck shapes in A (with your index finger at the seventh fret) so you can easily move between the two positions. Before showing you the basic melody of “On and On” Sharon shows you the L shapes and arpeggios in the key of A.
