This work in the Meredith Music Publications Master Class Series presents a comprehensive, interpretive analysis and performance guide of three major works for solo marimba by San Francisco Symphony Percussionist Jack Van Geem. The pieces are Velocities by Joseph Schwantner, Three Small Adventures by Gunther Schuller, and Fugue from Sonata No. 1 in G Minor. In this Master Class, Jack Van Geem outlines his philosophy of solo marimba technique and how mallet position increases a player's accuracy and provides an important aid in memorization. This in-depth, one-of-a-kind publication includes insights on sticking options, beating spots, hand and arm postures, memorization, and practicing as well as a complete edited version of the Bach Fugue from Sonata No. 1 in G Minor.
