Query: Serious Bass Technique

This is a very good book, especially if you are an experienced player and know how to read. Good for any level from intermediate to pro. Most of it is filled with repetitive exercises to develop good technical and harmonic skill with various chordal structures and rhythm. It's all there; patterns, drops, rakes, diminished, augmented, whole tones, blues, double stops, etc... He's got some really great sample blues lines that any player could easily add to his trick bag. Most of the fingerings are not specified, making you experiment and think for yourself how to get around. He states that this was his intention. Overall you can't go wrong with this method book. I feel honored to be able to vicariously study with the best upright player in the history of commercial and jazz music, for a mere thirteen bucks! He was truly the greatest!
