Thank you Greg for taking time to address that concern of mine as well.
I must admit it’s quite difficult to take a step back while developing new mental approach to trumpet playing.
Here most of us live in the apartment houses and while playing scales with some mistakes withing limited range can be a temporary shelter, playing long tones and singing Cs for months makes one look (sound) really silly. “What is he doing up/down there? Will he ever play music?”
– “Hey! You’ve played for years and I see (hear) you have no progress!”
– “Oh, you know – trumpet is such a difficult instrument! Blah-Blah-Blah…” 🙁
