(LKM Music). The idea for the Heifetz Scale Book was to present all the great master violinist Jascha Heifetz's scale routines that were developed over his long career, but never written down. This edition by Heifetz's protege and world-class violinist Endre Granat is a self-contained master class for a lifetime of study in virtuoso technique! Includes a deluxe leatherette cover.
