One would be the Sousaphone.
The modern family of brass instruments can be broken into valved brass instruments (trumpet, horn, euphonium, tuba) and slide brass instruments (trombone). Brass instruments could also be broken up into Cylindrical bore (constant diameter tubing like the trumpet and trombone) and Conical bore (increasing diameter tubing like the horn, euphonium, and tuba).
trumpet / sax
There are four types of musical instruments: String, Wind, Brass and Percussion.
If you're talking about meterology and the weather, the instrument that measures the wind is called an Anemometer. However, in terms of musical instruments, they are plainly refered to as the Wind Instruments, but can be further divided into two groups, the Brass Instruments and the Woodwind Instruments.
Trombone and euphonium/baritone.
Brass instruments can have valves or a slide, but not reeds. Brass instruments create sound by the vibrating of the player's embouchure in a mouthpiece, and the valves and slides on the instrument change the length of the tubing in the instrument which affects the pitch of the notes produced. Reeds are used in woodwind instruments to vibrate to produce a sound instead of using a mouthpiece like in brass instruments.
Brass is an alloy of copper (Cu) and zinc(Zn).Red brass is 85% copper and 15% zinc, while yellow brass is 60% copper and 40% zinc.It's important in chemistry to understand that brass is not a compound of copper and zinc; it is a homogeneous mixture of those elements. A compound contains at least two chemically bonded elements, copper and zinc in brass aren't bonded by covalent bonds, ionic bonds, etc.; they're simply mixed together to form brass.
The four instruments that are in the Orchestra are Bass, Cello, Violin, and Viola. All four are in the Strings section. The other three sections are: Brass, Woodwinds and Percussion. Two instruments in each would be: Strings: Violin & Cello Brass: Trumpet & French Horn (also Trombone and Tuba) Woodwinds: Flute & Clarinet (also Oboe, English Horn and Bassoon) Percussion: Snare, Tympany (plus a variety of other percussion instruments.
At least two french horns, four trombones, four trumpets, and two tubas.
Usually tuba, trombone, french horn and two trumpets (another trumpet player might play piccolo trumpet)
Brass and percussion are two very distinct and different categories of instruments. You'd be missing a huge element of a band with one and not the other.
