Tom has been posting so much great stuff with his chord studies and Rags and such that I thought I'd give him a hand (not that he needs it!).
Actually, I was just working thru some of my antique sheet music and ran across this little rag by Thomas Armstrong from the 1920's. It is in F (with the C part in Bb) and it made me think of Tom's "chord study in F". It has some interesting chords, some finger-twisting pull-offs and is a pretty neat exercise in F and Bb. Tune to gCGBD.
