Long Tone Duets for Euphonium (TC) by David Vining is appropriate for high school through professional euphonium players.
Long Tone Duets provides an opportunity for euphonium players to play long tones together, learning to blend tone quality, balance dynamics, and play in tune. Long Tone Duets contains a duet in every major key, and provides the perfect forum for teachers to discuss details of intonation, tone quality, blend, and balance with their students.
Additionally, the Long Tone Duets editions for euphonium, euphonium (TC), and tuba are designed to coordinate with one another. If you have the euphonium edition, for example, you can play along with a tuba player who has the tuba edition.
"Long Tone Duets for Euphonium provides excellent supplementary material for euphonium players of all ability levels. The exercises create an ideal approach for focusing on basics of tone quality, dynamics, articulation, and intonation—elements which are, of course, essential to success as an ensemble and solo euphonium player. I suggest incorporating a few minutes of these duets into EVERY lesson." - Philip Sinder, Professor of Tuba and Euphonium, Michigan State University
