Question:

How do you finger a high D on a trumpet?

I forgot how to do it and the material that I'm supposed to practice over the weekend uses this note.

Best Answer - Chosen by Asker: High D is first valve. This is a pretty high note, so be sure to set your lips before you play ;) Press down only the 1st valve, the one closest to you.
