You're a little gang boy retard that probably wear his pants down past his asscrack.

The word is MOLDING, you retarded f*ck. I am at least one order of magnitude more intellectual than you are, and at least two orders of magnitude more intelligent than you are, dumbshit.

And as stated, they ARE indeed different instruments, regardless of any common rooting, idiot.

You'd better hurry then, chump.

You are a clueless little bastard. Your mother should be jailed as a felon for the crime of not flushing the piece of shit you are, the moment she shat you out of her ass.

You're a goddamned retard.

A clarinet is a reed instrument, idiot.

Your original statement was that "the trumpet only has 4 notes per valve combination". You say you "played a trumpet" but you couldn't have ever developed any facility on it, otherwise you'd know that's just patently wrong.

Yes, it's true there are limited note choices with a given valve combination in the lower register but the harmonics get closer the higher you go. Add more valves and you're using a longer horn with more harmonics in the lower register. With a 1-2-3 combination I count

7 partials just in the first two octaves of low F# to F# on the top of the staff.

When you say "only 4 easily reachable" notes - I assume referring to the open horn - i.e. no valves - this may be true for a beginner who can't even get to G on top of the staff (which you need for "taps") or some old duffer who only takes it out of the case on Veteran's day or something but this isn't true for someone who's developed any kind of facility. Listen to even a good high school stage band and you'll hear higher notes that are plenty "solid".

Right I meant to use coronet

Unless you're kidding... you mean *cornet* Randy

A cornet is a bugle with valves. A trumpet has a straight pipe (2/3 straight - 1/3 tapered, IIRC) and a cornet tapered tube (2/3s tapered). The trumpet has a higher 'Q', thus a harsher sound. It's much like the difference between a trombone and baritone or euphonium. Same ratio of tapered to straight tubing.

I know that as a "triumphant trumpet"; the instrument they use at horse tracks for "The Call to Races". It is a trumpet, so has 2/3s straight tubing.

No, a short horn would give a higher pitch. The crisper sound is caused by straight tubing.

Look at the taper. The french horn is quite tapered with very little straight tubing. A trumpet or trombone has very straight tubing.

I don't think so. The fingering does not match the pattern of notes.

The apparatus shown in Fig. 6.9 (p 118) should have to be fitted into the robot head. The complexity of the artificial lips ("artifical mouth") with its mechanical constraints seem to indicate that the mouthpiece would have to be attached to it rather than to the trumpet body. I noticed only a small orifice in the robot's face where the mouth should be. Thus, the rumpet body should be only one side of a compressed air "Quick-Disconnect".

It downloaded readily for me in its entirety (except for the accompanying CD).

There is actually a lot of functional similarity between sound production in the trumpet and a double reed instrument such as an oboe.

Change the metal trumpet for an oboe like keyed body (cornetto), blow it mostly at the lower overtones, and you get a very oboe like sound.

Even in the higher overtones, it's long been known that a trumpet at a distance (where some of the brassiness dies out) can be mistaken for an oboe.

In fact, playing strictly on the high overtones of a longer brass instrument - boroque trumpet or modern french horn - gives a very woodwind compatible sound.

Historically speaking you had your horns which were mostly tapered, including bugles. And your trumpets which were mostly constant diameter except in the first and last sections. But after the introduction of valves the difference in the amount of tapered tubing largely went away. Any tubing inserted by a valve must be the same diameter at both ends, so the more valves that are engaged the lower the proportion of tapered tubing to overall length. Further, the diameter of the tubing in each valve tends to be the same as they are usually located adjacent to each other without much room for taper in between. There have been some exceptions with fourth valves on euhphoniums and fourth and fifth valves on french horns sometimes using different diameter tubing, but by and large the modern valved instruments carry a high, and nearly equal, fraction of their overall length as cylindrical tubing.

Until the mid 1800's trumpets were valveless instruments, most popularly single coiled about 9 feet long and standing in D alto. Being longer than bugles, a typical player could access more of their overtones and thus obtain more notes than on the shorter valveless instruments.

Other historical divergences include the keyed bugle, and Adolphe Sax's first family of inventions, the saxhorns, which are saxophone- hinting bodies lip-blown with brass instrument type mouthpieces.

Not true. Look at a cornet next to a trumpet. The cornet has far more tapered tubing.

A cornet and trumpet have the same pitch (same length), yet sound quite differently.

Of course instruments changed along the line; euphonium/baritone, double-base recorder/tuba/sousaphone.

Yet it can still be discerned by the trained ear. Any conductor could tell in a heartbeat.

But NOT in the valve area.

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.
