As the title indicates, 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 from every period of music literature from the Renaissance to the present day, so this colourful musical material also serves to deepen the youngsters’ knowledge of style. The majority of the works are transcriptions made specifically for this series that are adapted to the technical characteristics and sound of the given ensemble, and even the easiest pieces are of musical value. 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 from among their own pupils. The percussion volume is exceptional within the series, as it includes only contemporary, original compositions for four, five and six performers.
