"A 'user-friendly' scale book with each of the twelve keys complete on two facing pages. Dozens of bowings and rhythmic variants are offered to develop and improve evenness, clarity, agility, speed and intonation. An innovation introduction to double-stops takes the guess-work out of this important technique. The Circle of 5ths explains key signatures. The book includes three octave major, melodic minor, harmonic minor, arpeggios, broken 3rds and chromatic scales. Double-stops in octaves, thirds, sixths and harmonics are presented in two octaves." --
