The mouthpieces for some woodwinds, including the clarinet, oboe and bassoon, use a thin piece of wood called a reed, which vibrates when you blow across it.

What woodwinds do not use a reed at all?

The flute is different to the other members of the woodwind family as it does not use a reed, instead sound is produced by the flow of air across the opening, which makes the flute an aerophone instrument.

What instruments have no reeds?

There are two types of Woodwinds: the Flute and the Reed instruments, even though all them produce the sound by blowing them. The Flute family does not have Reed and it produces the vibration by blowing in its tone hole.
