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 D, not its enharmonic twin.

Frequently asked questions

How do I transpose from concert pitch to A instrument?

Move every note up a minor third — 3 semitones, 2 letter names up. Change the key signature the same way: music in C major becomes E♭ major.

What key is concert B♭ major for an A instrument?

D♭ major. Concert B♭ is the most common band key, which is why it is the usual example.

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.
