110/365 Blow here
I have played a brass instrument for as long as I can remember. I started when I was six and I’m still going at it, more than forty years later.
I’m enjoying at much now as I ever have. I’m not exactly Wynton Marsalis, but I can blow well enough to play in a good brass band. My pursed lips have been pressed against this mouthpiece too many times to count. There are, no doubt, large quantities of my DNA embedded in those tiny pits on the rim.
Never borrow another brass player’s mouthpiece.
