●9 BARRE CHORD RIFF WITH THUMB
We’ve designed this one-bar riff to be spookily similar to the main riff of Pete’s Blues, and it uses the chord shapes from Exercise 8.
As indicated in the music notation by the ‘T’ for ‘Thumb’, the fretting hand thumb is used to fret all the notes on the bottom string. The
two notes at the end of the riff straddle strings three and one and are plucked with both plectrum and finger.
●10 EXOTIC SCALE
We’ll finish with a swift demo of one of the ways in which Buchanan brought extra interest into his playing. At 1:53 of Pete’s Blues he breaks into a lead phrase using an exotic scale. Bar 1 shows one octave of this scale, ascending, comprising C Db Eb F G Ab B C. This scale could be thought of as the C Phrygian mode with a raised or natural seventh degree
of the mode; alternatively it could be thought of as the C harmonic minor scale with a lowered or flattened second degree. Bars 2 and 3 show a phrase using this scale.
