This version of Derivations by Michael Kamuf is part of our Belwin FLEX offerings and is designed with maximum flexibility for use by any mix of instruments---wind, strings, and percussion, including like- or mixed-ensembles with as few as 5 players. The suggested instrumentation and a customizable Teacher Map will help you plan out how to best assign parts to suit your ensemble's needs. It also comes with supplemental parts for maximum flexibility. With the purchase of this piece, permission is granted to photocopy the parts as needed for your ensemble. A percussion accompaniment track is also available as a free download. String parts have been carefully edited with extra fingerings and appropriate bowings to support students in mixed ensembles playing in less familiar keys. After a mysterious introduction, Kamuf's original work takes off with contrasting themes in both 4/4 and 3/4. Bold melodies, contemporary harmonies, and driving percussion combine to create a perfect opening or closing selection for your next concert or festival performance. Relentless! (3:00)
