| Just my opinion....but anything done to a trumpet can affect either/or the sound or the "responsiveness" of the horn. To work well, the body of the trumpet must "respond" to the vibration set up by your lips and then feed back some of that vibration into the air column that is vibrating within the tubing. Any change in mass, metal thickness, weight of finish, location of the "added masses", brace location and design, bell shape, leadpipe taper, tension from stressed solder joints, etc. will change the way the horn "responds". (If you don't believe me, try playing a horn with a broken brace then get the brace repaired and try the horn again!)
You may (or may not) be able to "feel" the difference, you may (or may not) be able to hear the difference. But rest assured that there will be a difference.
Remember...a trumpet sound (indeed, the sound of any wind instrument) is a combination of the vibration of the air column and the vibration of the body of the instrument (and how that body vibration is fed back into the air column).
I fooled around for a week or so with a Dennis Wick sound enhancer (a heavyweight metal "cover" for a mouthpiece which is held in place by two O-rings). It certainly "felt" different to me with some notes slotting "differently" (either easier OR more difficult). I ended up getting rid of it since I didn't think it was working for me and I was going to GR mouthpieces anyway. Whether I "sounded" different with it I can't say...a trumpet sounds mighty different from the "other side of the bell".[/i] |
