Watch the Listening To The Band online guitar lesson by Larry Carlton from 335 Blues Motifs
Using a blues track similar to Crosscut Saw in the Key of D with both organ and guitar rhythm parts, Larry stresses the importance of listening the band and then developing motifs that best fit and compliment the other parts.
Larry demonstrates how to imitate some of the lines and rhythms that the other musicians are playing. He also demonstrates how place your motifs between parts. Both are very effective approaches for establishing and then developing motifs.
