Concert pitch and written pitch
A trumpet in B♭ reads a whole step higher than it sounds, so its C major is concert B♭ major, the key most band music is in. Band directors teach the scales in concert keys (concert B♭, E♭, F, A♭…), which on trumpet are written C, F, G, B♭. The valve chart here covers written C; the table gives every major scale's notes as the trumpet reads them.
