Sarastro's Aria From Mozarts The Magic Flute arranged as a Euphonium Solo With Piano Accompaniment. This wonderful Aria returns the Euphonium to its original function that of the Operatic Bass voice. A good reading exercise for students combined with the Magic of Mozart makes Within These Temple walls a delightful Euphonium feature and is not to difficult for young players. I have included parts in Treble Clef In Bb, Bass Clef both concert pitch and in Bb. Also included is a Piano Accompaniment Backing Track in MP3.
