Which type of instrument uses a mouthpiece?

Question

Single-reed instrument
double-reed instrument
string instrument
percussion instrument

Answer 1

Both single-reed and double-reed instruments use mouthpieces. Single-reed instruments, like clarinets and saxophones, use a single reed attached to a mouthpiece. Double-reed instruments, like oboes and bassoons, use two reeds tied together and inserted into a mouthpiece. String instruments do not use a mouthpiece, and percussion instruments do not typically have one either.
