Woodwind instruments

Woodwind instruments, (also called woodwinds) are a family of musical instruments within the more general category of wind instruments. There are two main types of woodwind instruments: flutes and reed instrument (otherwise called reed pipes). What differentiates these instruments from other wind instruments is the way in which they produce their sound. Woodwinds can be either soprano, tenor, alto or bass. 

Flutes produce sound by directing a focused stream of air across the edge of a hole in a cylindrical tube. The flute family can be divided into two sub-families: open flutes, and closed flutes.

Reed instruments produce sound by focusing air into a mouthpiece which then causes a reed, or reeds, to vibrate. Similar to flutes, Reed pipes are also further divided into two types: single reed and double reed.
