Transposing D trumpet part for Bb trumpet?

I am playing with orchestra on one of their songs and the trumpet part is a D trumpet I was wondering how do you transpose a trumpet in D part so you can play it on a Bb trumpet?

Transposing D trumpet part for Bb trumpet?
Ya, you'll have to bring everything up a major third, so transpose the key signature up a major 3rd, and then, a handy trick is to read everything up a line or up a space. Imagine that the bottom line of the staff is on top of the staff. This works quite well for me anyway!
Reply:On D trumpet, written "C" = soundind "D" (one step above written note)





On Bb trumpet, written "C" = sounding "Bb" (one step below written note)





write %26amp;or play everything up 2 whole steps (a major 3rd),


for example; you have a written c which = sounding D which means if you play an E on your Bb trumpet, you get the correct pitch.
Reply:the person above pretty much summed it all up. hehe would you by any chance be playing an excerpt from Handel's Messiah?
