Question about music transposition
I'm really new to music theory and I'm trying to figure this out. I need to transpose a score in B major to the key Bb major. When I click transpose, should it be up, or down, and what interval should it be?

From B major to Bb major is one semitone down. On most computer music programs this would be achieved by changing it -1.
Technically you can get from one key to another in either direction, up or down since the 12 notes cycle around but in this case -1 is the obvious choice since the other option is +11.
I've seen transposing function in a few different notation programs. They will differ from program to program, options I have seen include:
direction up/down
interval of transposition
diatonic or chromatic
Watch out for enharmonic spelling changes
Sometimes software offers a 'key change' type function.
You need to transpose down one half step. If you have a diatonic/chromatic option, you want to do it chromatically.
