Single reed instruments, such as the clarinet and saxophone, have a single piece of cane or synthetic material attached to the mouthpiece. When air is blown through the mouthpiece, the reed vibrates against the mouthpiece to produce sound. Double reed instruments, such as the oboe and bassoon, have two pieces of cane or synthetic material that are bound together and vibrate against each other when air is blown between them. The sound produced by double reed instruments is distinct and often has a more nasal quality compared to single reed instruments. **
