Shortly after I started studying with Carmine in 1973, he started wearing flight line ear muffs
during lessons. Apparantly he was starting to have dizzy spells, one of them occurring down
on the street, and it was diagnosed as resulting from having too much exposure to very loud
trumpet playing, especially in the high register. I think one his students was a pilot and brought
him the ear muffs. They worked perfectly in that they protected his inner ear and in no way impeded
his ability to analyze a student's embouchure.
