I just watched a Youtube video of Brother Phil and it called him a "one of the greatest jazz trumpeters" playing..... blah blah blah music. I never thought of Phil as a jazz trumpeter. Am I correct in this or not? I just thought he improvized on the music, but not necessarily jazz. Next question. If you learn "jazz" I assume you learn to improvise. If that is a correct assumtion then can you play any music and improvise without actually playing jazz?
