Watch the C#, B, F# Groove: 1 online guitar lesson by Andy Aledort from Progressive Blues Power

Let's switch things up a bit for our examination of improvisation in the key of C# by laying down a rhythm part that moves from C#7 to B7 to F#7, not unlike the soul/R&B nugget "Stop," covered wonderfully by Jimi Hendrix and the Band of Gypsys during their infamous New York Fillmore East shows recorded on New Year's Eve, 1969/1970. Notice in particular the reliance on thumbed chord positions throughout this section.
