1. Dragonfly: • Focuses on the development of precise interval changes, primarily with the outer mallets. Interval ranges include M2 up to an octave, but the shifts move mostly in stepwise motion. 

2. The Dark Side of Marimba Playing • Intended to practice long jumps and fast interval shifts in a smooth and controlled manner. • Inner voices maintain a roll on dissonant cluster chords while outer voices jump for single notes. • Uses octave intervals. 

3. Marimba Etude for Octaves • RH plays double verticals in larger intervals (up to a 10th), while LH outlines the harmony with arpeggios. • Works on developing the interval switch from 6th to octave 

4. Hochzeitsmarsch • Arranged to help develop one-handed rolls in both hands. • May also help develop fast, relaxed motion on double verticals and quick shifting around the instrument.
