Introduction to Acoustic Blues. Using instructional text and actual songs, author Kenny Sultan covers blues in five different keys and positions and shows how they can be adapted to any key. Along with the basic blues rhythms and leads, fingerstyle blues is covered, using both an alternating and monotone bass. Sultan also touches on the specific techniques of various well-known players, open tuning, and bottleneck guitar. The accompanying CD includes each example and every song, most of which are played both in slow speed and at regular tempo.
