The volume of trios for advanced players mainly offers a selection from works of the most prominent and most popular composers (Bach, Händel, Haydn, Mozart and Beethoven). Of special interest are extracts of Beethoven's variations composed on the famous theme of Mozart's Don Giovanni, Fughetta by Robert Schumann and Dream by the less well-known composer Benjamin Godard.

The volumes in this new series contain duos, trios and quartets, their degree of difficulty ranging from easy through intermediate to advanced. Every piece is a transcription or an arrangement, since in editing the volumes our primary concern was to provide a collection of valuable and interesting compositions, as freely variable as possible as regards instrumentation, for music school students and also for adults who make music for their own pleasure. The range and pitch of the parts enable the works to be performed on any required or possible combination of the given instruments.
