Every note
Each note is moved by letter as well as by pitch, so a sharp stays a sharp and a flat a flat — B becomes E, not its enharmonic twin.

Frequently asked questions
How do I transpose from E♭ instrument to B♭ instrument?
Move every note down a perfect fifth — 7 semitones, 3 letter names down. Change the key signature the same way: music in C major becomes F major.
What concert key is E♭ music written in C major?
E♭ major: E♭ instrument sounds a major sixth lower (or a minor third higher) than the page.
Why does the chart choose D♭ major instead of C♯ major?
Where a key could be written two ways, the chart picks the one with fewer sharps or flats, the way band and orchestral parts are printed: D♭ major has five flats, C♯ major seven sharps. The notes are the same.
