I am sitting here late at night thinking over a glass of scotch, itching badly to play my newly acquired horn but unable to because of the noise at this time, and began to wonder about using things like an empty pop can for a mute. Or possibly crimping a piece of aluminum foil over the bell to produce some sort of effect . I tried to search for any kind of information of people doing this on the internet and surprisingly came up with nothing, not even failed attempts. I couldn't possibly be the first person to think about putting a sheet of foil over the end of your trumpet, was wondering if anyone has any experience with this or has heard of anything similiar. I'm gonna try it first th ing in the morning and I'll let yall know how it goes.
