Euphonium are the tuba-euphonium quartet or larger tuba-euphonium ensemble; the brass quintet, where it can supply the tenor voice, though the trombone is much more common in this role; and other mixed brass ensemble. Such ensembles are almost non-existent: they are more likely to be semi-professional or amateur in nature. Most of the United States Armed Forces service bands include a tuba-euphonium quartet made up of players from the band that occasionally performs in its own right. The euphonium is not traditionally an orchestral instrument and has not been common in symphony orchestras. However, there are a few works from the
St Catherine's School, Toorak in Year 3 & 4, and a brass or woodwind instrument in Year 5. These small group lessons allow students a ‘hands-on' experience including opportunities to perform throughout the year. The school also offers a comprehensive Instrumental Program in all instrument families (including string, woodwind, brass, voice, percussion and keyboard instruments) where students learn with specialist teachers in classical and contemporary styles. Individual tuition from highly qualified specialist instrumental staff is available on the following instruments: Violin, Viola, Cello, Double Bass, Flute, Clarinet, Oboe, Bassoon, Alto Saxophone, Tenor Saxophone, Horn, Trumpet, Trombone, Tuba Piano, Harpsichord, Recorder, Classical singing, Jazz singing
