Quint Etudes: Violin (Suzuki Violin School). Revised Edition.

Students learn to listen to sound more carefully. Although almost everybody plays with beautiful tone while tuning the violin, many press the bow and make a terrible sound when they start playing, especially double stops. The first exercises in this book are to practice playing the double stops with beautiful tone while listening to the resonance. There are exercises to shift the fingers between the G string and the E string, moving upward and downward in fifths. There are also many exercises to practice listening to the resonance of open strings.
