How does woodwind instrument's use waves?

Woodwind instruments produce sound by creating vibrations in the air, which are generated when a player blows air into or across a mouthpiece. The air column inside the instrument vibrates at specific frequencies, determined by the instrument's shape and the presence of finger holes or keys that alter the length of the air column. This modulation of air pressure and wave patterns results in the characteristic tones of woodwind instruments. Different techniques, such as varying embouchure or using multiphonics, can further shape the sound waves produced.
