By Jean-Marc Pillard. Walking Bass Lines for Guitar teaches excellent techniques to use in a duet format, either with another guitar player or with a singer or other instrumentalist. The idea of this book is to give a few answers to the question, "How do I harmonize walking bass lines when I've never done it before?" Most examples are written in G or C for convenience but obviously will need to be transposed into the other keys. Jean-Marc Pillard teaches Harmony and Jazz Guitar at the Conservatoire de l' Quest Vaudois, and plays with his trio, "Jazz Standards".
