The volumes in this series include works composed or arranged for chamber ensembles (trios and quartets), specifically designed for music school students. The editors have selected music literature from every period from the Renaissance to present day, and as a result this colorful musical material also serves to deepen pupils’ knowledge of musical style. The majority of the works are transcriptions made specifically for this series and are adapted to the technical characteristics and sound of the given ensemble. Of the twelve volumes in the series, five are designed for groups consisting of one type of instrument (ensembles of three or four flutes, violins, or horns), thus the teachers of each instrument can form chamber groups among their own pupils. The percussion volume is an exception within the series, as it includes only contemporary, original compositions for four, five, and six performers.
