This book provides the most efficient way to practice scales and the fastest path to mastery of one's instrument. The scale routine presented here is a vehicle for increasing tactile familiarity and improving facility, velocity and tone. Its very nature-namely its function outside of specific repertoire-allows one to focus on the technical things ideally relegated to one's subconscious when performing music in a real-world context. This book isn't an encyclopedia of scales; rather, a comprehensive way to practice scales (and for that matter, arpeggios, chords and patterns). It is suitable for all instruments.
