Watch the Double Stop Hammer On online guitar lesson by David Hamburger from Fingerstyle Blues Factory
This lick makes use of the same chord shapes as the first measure of Double Stop Boogie, only in this case we stay at the fifth position until halfway through the second measure. Also, you’ve got to bar at the fifth fret cleanly from the fourth through the first string in order to get that high A to ring out at the end of measure one. These two licks and the one that follow are loosely based on the playing of New Orleans pianists like James Booker and Professor Longhair. No one knows for sure, but the whole boom-chuck alternating-thumb approach to blues guitar may have been derived from the playing of much earlier blues pianists; whether that’s true or not, there’s a great deal of inspiration to be gained in the playing of blues pianists of all eras.
