+1 --so far I havent needed a mute -- that really screws up my "hearing" the horn. I suspect if I needed to, then I could use the mute in conjunction with the tuner --- and work on it from there. Yes -- so far I have had ample time to remember the songs, while usually getting several weeks advance notice of when I am going to play. Recently I was supposed to be in the worship service with all the instruments (guitars, keyboard, drums, ect, ??? harmonicas, banjos, harps and singers) -- but a touring musical group came by and filled that spot. So I suspect at some time in the future ---it will all come together with more than just a trumpet solo ---might need the dots then ---- time will tell, but it is all good play and be happy -- what more can one ask???
