Final answer:
A woodwind instrument that can be used as an answer is the flute, which produces sound by blowing across the mouthpiece and pressing keys to change the pitch.
Step-by-step explanation:
When discussing woodwind instruments, we are referring to a family of musical instruments within the more general category of wind instruments. A notable characteristic of woodwind instruments is that they produce sound by the splitting of an exhaled air stream on a sharp edge, such as in the case of flutes, or by the vibration of a reed, as seen in clarinets and oboes. One member of the woodwind family that would qualify as an answer to your question is the flute.
The flute is a wind instrument made out of a tube with holes covered by keys that are pressed down to change the pitch of the notes produced. Its sound is created by blowing across the edge of the mouthpiece. Other examples of woodwind instruments include the clarinet, oboe, and saxophone.
