Usually, 4 Horns/French Horns, 3 Trumpets in C, 3 Trombones (3rd plays bass Trombone and can double on the Euphonium if a piece calls for it) and 1 Tuba.
However, some pieces sometimes call for 8 Horns/French Horns (and then the 5th through 8th double on Wagner Tubas, again if the piece calls for it), sometimes 4-8 Trumpets, some playing Cornets, Piccolo Trumpets, Fluglehorns or the Bass Trumpet, once again, if the piece says to. Sometimes your will see 6 Trombones, 2 to each of the 3 parts, but no matter what, the very last trombone, the one closest to the Tuba will always play the Euphonium when directed to in a piece. Once in a while there can be 2 Tubas which is common but you will usually find only 1 Tuba in an Orcastra. I really hope this answered your question well enough.
Trumpet and trombone, usually with four of each.
Most trombones are made of brass hence the name brass instruments.
FALSE.
Brass instruments tend to be made out of brass or other metals/alloys. Woodwind instruments have reeds, which makes a different sound to the brass instrument (in simple terms you have to blow raspberries into to make a sound- it is a little more complecated than that, but its hard to explain).
Instruments with wood mouthpieces, or mouthpieces containing wooden reeds, are called woodwinds, regardless of the material used to make them - and many are made of brass. "Brass" instruments - trumpets, tubas and other horns - have metal mouthpieces without reeds.
The tubing wraps around the way it does because if it was all one straight line, the horns would be too long to play.
to make brass instruments like trombone and baritone
the more the material used to make an instrument the flatter it is. that's what brass instruments need to be. so, they use alot of material they jus roll it and turn it alot (:
strings, percussion, woodwind and brass
to make up the length for the sound
One difference is that woodwind instruments use a wooden reed to form the mouthpiece. The reed sits at the back of the mouthpiece (on the bottom lip) and vibrates against the rest of the mouthpiece to help create the sound. Brass and woodwind instruments are both played by blowing into them (or over them in the case of the flute). Brass instruments do not have any moving parts that vibrate to create a sound. They merely amplify the sound created by the players lips vibrating. Woodwind instruments have a reed that vibrates except for the flute which splits a column of air to make vibrations. Brass instruments change their pitch by changing the length of tubing which the air passes through. Woodwind instruments change their pitch by changing the where the air escapes from the instrument.
Well because brass and percussion instruments have different sounds they can be combined in order to make music more interesting and have a different sound than each one would have individually.
