In the hands of a skilled player, a euphonium with a compensating fourth valve can play B0 to about A5. The range between B0 (the piano's third lowest note) and B1 is played with pedal notes, and a player with great lip control may be able to get as high as B5. Most euphonium music is written between B♭1 and B♭4.  Euphoniums are noted for keeping their rich velvety tone across their range.
