Watch the Badge: Ex. 1a online guitar lesson by Andy Aledort from Kings of Rock & Roll Vol. 5: Eric Clapton

"Badge" is a song Eric Clapton recorded with Cream for the band's last album, Goodbye, and this solo excerpt is along the lines of what he played over the first eight bars: over a chord progression of Cadd9-G/B-D, I use a combination of the D minor pentatonic scale (D F G A C) and the D major pentatonic scale (D E F# A B); switching between these two scales is a staple of blues and blues/rock soloing, and, in Eric's case, reveals the strong influence of B.B. King on his playing.
