Wish I was a brass player back in high school.

I envy brass players. Woodwinds never had a silent brass at wwbw thing to use. See, a clarinet is an instrument that has (if recall) a 4 octave range. Those high notes are crazy high are a painfully shrill if played wrong.

But brass instruments don’t have to worry about that. They can just pop this thing in and bam practice as loud and long as they want as their sounds are muted to the outside word yet are privately heard. Envy!
