Why is the oboe part of woodwind family?

The oboe is part of the woodwind family because it produces sound by vibrating a reed against a mouthpiece. Woodwind instruments all produce sound in this manner, and are distinguished from other instruments by this common characteristic. The oboe is a double-reed instrument, which means that it has two reeds that vibrate against each other. Other double-reed instruments include the bassoon, the English horn, and the piccolo oboe.
