The air doesn't make the sound, the trumpet player's lips have tovibrate, similar to a reed instrument - the trumpet tunes thevibrating column of air and couples it, via the horn, to theenvironment. Lips/breath are excitation, length of pipe is the tunedcircuit, horn is the impedance matching element. Now getting a robot to do it? A trumpet player starts the note bypressurizing the mouth, tensing the lips, then suddenly removing thetongue to start the note - similar to spitting material off the tip ofone's tongue.Without those elements it is bound to sound different even if a robotis producing the sound by blowing air into the instrument. - the cheapeasy way would be to add a reed to the mouthpiece and that would makeit sound more like an alto sax? I do know for a fact that there's a church in NYC that has a few dozentrumpet - bugle pipes (one for each note) on the pipe organ and itdoes sound like a trumpet so there must be an organ maker that knowshow to do it. Strictly speaking, it wouldn't be a trumpet any more ifit had a reed in it.Lip tension and pressure will get four notes per valve or combinationof valves - 4 solid notes; with good players able to hit severalhigher notes per valving. A bugle is basically a four noteinstrument, a valve bugle is an eight note instrument.--

Bullshit. They do not need their tongue at all.

Ah, now Dimmie, it's the holiday season. No need to get yourself all worked up. Why don't you go through mommy's laundry again. She might have gotten some new socks for Christmas. You'll feel much better.

Perhaps a few decades from now, your mental age will grow beyond that of a twelve year old adolescent little puke.

Now Dimmie! Is that any way to be? What's the matter, did mommy give all her socks to the Salvation Army?
