Assuming you mean "tuba" and assuming you mean "why does the tuba play lower notes than the Trumpet," the basic answer is, because the tuba is longer (it has more tubing).
regular trumpet? pull.
Valves, tuning slide, and spit valves.
Larger (longer and wider) pipes have a lower resonant frequency than smaller ones. The typical "trumpet" (which is often actually a cornet) plays about two octaves higher than a typical tuba.
A Conn Brass Trumpet is much shinier and a slightly silver-y color unlike a plain one which is bronze. They are also capable of playing deeper notes than plain ones.
their is a G trumpet. F trumpet B flat trumpet and a Piccolo trumpet being the smallest trumpet and an octive higher than a regular trumpet.
No. While you can make a "trumpet-like" sound with something as simple as a cardboard tube, making a trumpet which can play specific pitches requires years of practice and study.
Yes,Saxaphone is better than trumpet.
A piccolo trumpet has a higher pitch than that of a traditional trumpet.
Yes, the trumpet 1 part is normally harder than trumpet 2 or 3 and normally the best player or players play on the first trumpet part.
A gouge is deeper than a nick.
it depends on the key but about 4 feet.
any tube can be used as a trumpet but your best bet is 4ft of hose a funnel and a mouthpiece connected together using jubilee clips.
