Keep in mind that I'm talking mostly about trumpet pitches in this video, which are written a whole step above concert pitch (guitar, piano, etc.). So an A on piano is written as a B for trumpeters, but the pitch of the note is the same. I know, I know, it's weird and confusing. Don't shoot the messenger.
This is a lesson from the "Dark Eyes" video course for intermediate and comeback trumpet players. It's got pages and pages of downloadable sheet music, downloadable backing tracks at multiple tempos and styles, and over 40 videos. Check it out at TrumptJumpstart.com
