These are some resources I’ve found helpful in my trumpet practice:
An amazing and generous resource provided by trumpet player and teacher Greg Wing with PDFs and play-alongs. The material is mostly affiliated with William Adam’s teaching (Wing was a long time student of the great trumpet pedagogue). Tom Walsh first introduced me to these concepts and has a few great videos on “The Routine”.
Loads of interesting videos on a rage of subjects, mostly relating to trumpet efficiency. I am grateful to Noel Langley for hipping me to these years ago. I always recommend Spence’s Five Basic Videos to new students regardless of ability or experience. Spence also runs subscription course on his website that I got a lot out of.
A thorough presentation on the teaching of Claude Gordon with helpful demonstrations.
