Which range corresponds to the Euphonium?

The Euphonium is primarily in the bass clef and is a brass instrument known for its rich and warm tone. Its practical playing range typically extends from the written B-flat one octave below middle C (B♭1) up to F, which is a little above the staff (F5). This encompasses a comfortable range that most euphonium players utilize in ensembles and solo performances, allowing them to effectively navigate both melodic and harmonic parts in a variety of musical settings.

The selected range corresponds accurately to the instrument's capabilities, accommodating the typical tessitura where euphonium often performs. This range allows for the expression of dynamics and tonal qualities that the instrument is well-known for, especially in orchestral or band settings. The other options either span a range that does not align with the euphonium's intended use or extend beyond its comfortable performance limits, making them less suitable for the instrument in practice.
