28 etudes or duets or solos with piano accompaniment depicting various holidays throughout the year. These etudes received first prize in the Tuba Universal Brotherhood Association's 1996 Composition Competition. The etudes are published in duet form in order for them to be used as either an etude book and/or a duet. They can be played by any combination of instruments by purchasing the appropriate books. There is a separate piano accompaniment book. The second part is designed to be playable by the teacher or a more advanced student. The tenor and alto clef books can be also used for practice of these clefs by bassoonists and trombonists.
