Four mallet technique is required for both players in this four movement duet. The first movement is fairly quick with many time signature changes from triple to duple and back. The second movement is slower and set completely in 6/8. It has a lilting feel about it. The third movement is marked ìAlla breveî and is in 3/2 and 2/2. The final movement is very brisk with many time changes like the first movement. This is the most rhythmically challenging and exciting of the four movements.
