Perpetuum is a lively and contemporary addition to any concert performance with its memorable melodic lines and relentless driving rhythms. The piece begins with a powerful introduction to the main theme which is ingeniously augmented as the piece powers forward. The middle section provides a warm, lyrical contrast performed by the lower strings. The main theme returns with a wall of sound heading to a dramatic close. This beautifully expressive and contemporary work is a nice change of pace for orchestra students. Using the optional percussion parts are highly recommended for optimal effect.
