The air doesn't make the sound, the trumpet player's lips have to vibrate, similar to a reed instrument - the trumpet tunes the vibrating column of air and couples it, via the horn, to the environment. Lips/breath are excitation, length of pipe is the tuned circuit, horn is the impedance matching element.


Now getting a robot to do it? A trumpet player starts the note by pressurizing the mouth, tensing the lips, then suddenly removing the tongue to start the note - similar to spitting material off the tip of one's tongue.


Without those elements it is bound to sound different even if a robot is producing the sound by blowing air into the instrument. - the cheap easy way would be to add a reed to the mouthpiece and that would make it sound more like an alto sax?


I do know for a fact that there's a church in NYC that has a few dozen trumpet - bugle pipes (one for each note) on the pipe organ and it does sound like a trumpet so there must be an organ maker that knows how to do it. Strictly speaking, it wouldn't be a trumpet any more if it had a reed in it.


Lip tension and pressure will get four notes per valve or combination of valves - 4 solid notes; with good players able to hit several higher notes per valving. A bugle is basically a four note instrument, a valve bugle is an eight note instrument.

Bullshit. They do not need their tongue at all.

If you had any brains, you could tell by the sound that it was a horn sound, and that there was no reed involved in making the reverberations.

Why would you make a remark as if fact, then finish it with a question mark?

Except that it wasn't a bugle, it was a trumpet.

Well idiot, its like this, I played a trumpet, but never a sax. I know a trumpet needs the lips as the vibration source, I can only imagine what a trumpet with a reed would sound like so the question mark. Idiot.

I played in a few bands and orchestras and sampled a few instruments. Clarinet, Bassoon, Saxophone, use reeds. French horn, Trumpet, Trombone use lips. And air . . . and tension to achieve different notes

While the trumpet only has 4 notes per valve combination it is possible to "slur" from one to the next, and a good player can make it seem seamless - but can't stop and hold a note between two normal notes. Maybe Winton Marsalis can, but I seriously doubt it.

A clarinet, sax, virtuoso can slur and more easily hit illegal notes because the valves can open part way - trumpets not so lucky.

And I built a few pipe organs, idiot. The pipe organ is a flute with one pipe per note. There are also reed pipes and are used in pipe organs (with tunable reeds - but the pipe length and volume determine the note) Reeds alone are used in smaller organs - similar to an accordion or harmonica in design - both reed instruments.

A pipe organ with flute toned pipes uses combinations of pipes to make different sounds - emulating human voices or other string or wind instruments (different "stops" or multiple linked valves in the "wind chest") - but to make a pipe organ that sounds like a reed instrument you really need a reed at the base of the pipe.

A reed has all the warmth of a electromechanical seatbelt buzzer until you add the pipe.

ChairmanOfTheBored thou doth be a vicious troll.

A trumpet is a bugle with valves to change the length of the pipe. Are you the only person on Earth that doesn't already know that?

Since the robot wasn't playing a sax, I hardly think it has any relevancy whatsoever. I

Well, dumbfuck, if you had enough brains to read the entire thread, you would have noticed where someone got a PhD for making a device that simulates the human lips playing a horn instrument, and that it is quite possible.

Oh boy! An instrument "sampler". Do you play the skin flute as well?

That's Wynton Marsalis, idiot.

But YOU can slur right here in Usenet.

Oh boy! A pipe organ builder!

I don't need a primer, dipshit.

snipped retarded, half witted spew about tuned pipes.

You're a goddamned retard, boy.

You're a goddamned idiot as well.

Ergo NOT a bugle, idiot.

Are you the only dope on Earth that actually claims to have musical instrument playing ability that would claim a trumpet is a bugle? I think so. Bwuahahahahhaa!

Well, insisting on bottom posting net Nazi (well how do you justify inter posting? while disallowing bottom posting?)

It may be possible to make simulated lips to play a horn, seems very simple, but I wouldn't expect it to sound authentic. Just like every other synthesized instrument never quite sounds like the real acoustic thing. Lips, mouth, tongue, tension, feeling, soul - if you will grant that much.

Still don't believe lips vibrating cause the notes? That was one of your digs - now you are taking it for granted? What? something you were ignorant of? "lip-vibrated aero phone" is an ancient description of bugles.

Yes, it is possible to start a note without the tongue - but it sounds wrong - not a trumpet sound. And it is slow - you just can't get the fast short accent notes. Might be OK for Pachebel's Cannon but never cut the mustard for Spiritoso, e staccato. But you would already know that Mr all knowing?

I like fake music. I wouldn't trade Litztronic's Franz Litz's Totentaz (undoubtedly spelled wrong if you need to nit pick) for anything - but nothing, yet can emulate a real acoustic instrument.

You probably do need a primer dip s*it. Do you believe the sound of a pipe comes out of the end? due to air flow?

Well, I may well be an idiot AS WELL. Doubtless there's lots brighter lights than you or I on the block.

You self righteous pig. No one can be as ignorant and as abrasive as you except religious zealots or a damn good Leza (Chatterbox).

Which are you?

Of course not. The bugle predates the trumpet. The trumpet and bugle are identical when it comes to playing ability - although the trumpet is more complex and takes longer to master the lips and breath are the same - there's just many more notes. The trumpet clarinet et al, and trombone, French horn, all evolved from the straight bugle or horn (fanfare horn)

I might grant that a French horn sounds like a trumpet without the tongue - but even it is more mellow and rounder and can never hit the sharp staccato notes.

Bwuahahahahhaa!

I never said that, idiot. In fact what I said was that vibrating lips ARE what cause the tone, you stupid f*ck.

No, it wasn't. Learn to read, idiot.

You being dumb is a modern description of an illiterate twit... YOU.

Learn how to read, dipshit.

Grow the f*ck up, you retarded twit.

Idiot. Every time you open your mouth you prove you remarks were wrong. The mere fact that you delineate (not too big a word for you is it?) between the two further proves that they are not the same instrument.

snipped retarded, unrelated tripe

The subject is about bugles and trumpets, idiot, not any other member of the horns class, and no, we do not need a primer on which came first or the differences between the two.

The fact that you are describing differences proves I was correct. TWO DIFFERENT INSTRUMENTS.

Damn you should be in politics. What am I thinking, you ARE a politician.

Is a clarion just a trumpet with the second loop unrolled? ;-)

Cheers! Rich

Secure in your own little world. I bet you buy into the (some) religious zealot indoctrination. Head in the sand, wannabe intellectual.

Yeah, that's you. Signed sealed and delivered - and moulding in his safe grave.

OK ENOUGH ALREADY WITH THESE truculent arguments!

DO NOT CROSS-POST TO ALT.SCI.PHYSICS.ACOUSTICS since we care not about your predjudices.

Angelo Campane;;a

Apparently you do indeed need a primer - more like you need to start over.

not arguing they are different instruments - you don't read very well

- you couldn't even make a good troll. The bugle or fanfare horn - just "horn" to the ancients is only a pre curser - a branch of the evolution of horns. Bugle, Valve Bugle,Trumpet, French or Trombone are different instruments who owe their existence to the fanfare "horn" or straight bugle.

You know the self-righteous thing is curable if you get to it before the age of 10 or so. I pity you the indoctrination you must have gone through to be so sure of . . . well of everything.

Much as I'd like to kick your drooling chops some more, I have to be somewhere else.

Merry Christmas

Not sure where you're getting this "four notes" from. Any valve or combination of valves yields far more than four notes.
