Each solo in FESTIVAL SOLOS BOOK 3 has two downloadable audio files. One provides a model for you, with a professional musician playing your part with piano accompaniment. The other is the piano accompaniment only with which you can play along. You will hear either flute, oboe, bassoon, clarinet, or alto saxophone playing the woodwind solos, and either trumpet, horn, trombone, or tuba playing the brass solos. The mallet solos are performed on marimba and the percussion solos are performed on the exact instrumentation each solo was written for.
