This new edition of the Wohlfahrt Etudes is a masterclass in book form by acclaimed soloist Rachel Barton Pine . She discusses dynamics, augments Wohlfahrt's own bowing suggestions with her own, and provides solid advice for approach to the Etudes. Along with all of this, the book comes with audio tracks of performances of all Etudes by Matthew Lipman for study. Not just a new edition, Pine's approach to Wohlfahrt is holistic guidance to ensure the best possible use of this standard pedagogical foundation.
