What is the pitch range on the euphonium?

Answer 1

The basic range when writing for the instrument might be considered EE (the E below the fourth ledger line under the bass staff) to f (second line from the top of the bass staff). Many high school and college players will be able to play well up to middle C, of course, but many won't, and in typical band and orchestra literature the extended high register won't used nearly as much.

Tubas with a fourth valve can reach down to EE-flat and DD, and this turns up in band and orchestra literature; notes below these are also possible, but intonation will begin to vary a great deal depending on the instrument and the player. I haven't seen lower notes called for very often except in solo literature.

Then there are the pedal tones, of course--beginning with BB-flat (the B-flat right above the lowest note on a piano). Most players can learn to play these, but they aren't called for much. The lowest pedal tone I ever managed was a GG-flat, down below the lowest notes of the piano, but that's just practice-room horseplay. :-)

Now for the high range: of course there are gifted younger players who have managed a high range well above middle C, and this range does turn up in solo literature. The best I ever managed consistently was E-flat above middle C, which is nothing special; though after playing Trumpet for a semester I actually played C above middle C on the tuba--in a weird, thin sort of sound that no one else really wanted to hear.

Hope this helps. I should mention that I'm describing the BB-flat tuba, common in bands; range would be similar on the C tuba, but the E-flat and F tubas are pitched higher and obviously have a bit easier time on the upper notes, but may lack some of the lower pitches.
