D is another great key for exploiting the use of open strings for improvised solos. D minor pentatonic and the D blues scale include the notes A, D and G, all available as open strings. Using the open strings invites multiple pull-offs and hammer-ons for fast, smooth phrasing. You will hear great examples of blues phrasing using open strings in this way in the playing of Johnny Winter, Ry Cooder, Stevie Ray Vaughan, Jeff Beck and many other guitar greats.
