The lowest pitched and largest brass instrument known is the tuba. The tuba is one of the newest members of the modern symphony orchestra. It was first publicly played in the middle of the 19th century when it took the place of the ophicleide. The player produces sound by vibrating his lips against a large cup-shaped mouthpiece.
The snare drum is a member of the percussion family which means that it is played by being struck. It has strands of snares that are curled metal wires, plastic cables, gut chords, or metal cables extended across the bottom of the drum. It is cylindrical with skin stretched out at its top. A wooden drumstick is used to strike the top head which is also called batter-head. Many consider the snare drum to be one of the most significant drums included in the drum set.
The acoustic guitar is hollow-bodied and uses only acoustic techniques to produce sound which means it does not have electric amplification. Its name is a retronym of the electric guitar to differentiate them from each other. Its strings could be made of steel or nylon while its top plate could be made of cedar or spruce. At the top is a circular hole with a diameter of 3.25 inches to 3.5 inches which strengthens and reinforces the produced sound.
