I need to learn to efficiently transpose as I play music in my youth orchestra. I was learning on my Bb and was still pretty bumpy, but I recently got a C trumpet to learn on. I know it's only a step up, but I still feel like I hit ground zero with this. What is the most effective way to learn transposing while playing? I never took a music theory course so I really just have a basic idea like how many sharps and flats are in a scale.
