How do I transpose tuba C bass clef into B flat treble clef?

Question:First, it depends on the instrument you are transposing it for. The Bb Treble-clef Baritone horn have similar range to a tuba, so the transposition will be fairly straightforward. On the other hand, a tenor sax (also Bb treble clef) has a completely different range so you will need to be more creative in writing the part out.

Assuming you're writing for baritone horn:

1.) Find the overall range for the part you are trying to transpose. If it is in a higher part of the tuba's range, you can play it at the same pitches; if it in the lowest part, you will need to play it an octave higher.

For example, the lowest E on a three-valve tuba (below the bass-clef staff) would correspond to the lowest E on Baritone treble-clef, which would be the E below the treble-clef staff. On the other hand, a C on the second space of bass-clef could be played as the C one ledger-line below the treble clef. (Since the baritone horn treble-clef sounds an octave lower than written, this works out to be the same note.)

2.) Now apply Bb transposition rule: write all the notes a major-second higher in pitch (changing the key signature if necessary) so that when they are played, they sound at the correct pitch.

3.) For the two examples above: the lowest E on the tuba would be written as F# below treble-clef and the C mid-staff would be written as D on the bottom of the treble-clef staff.
