Identify the part which vibrates to produce sound in the following instruments: Flute

In a Flute, the part that vibrates to produce sound is the air column inside the instrument. When a musician blows air across the edge of the embouchure hole (mouthpiece) or blows air through a mouthpiece directed towards the edge, it creates vibrations within the column of air. These vibrations generate sound waves that resonate within the flute’s hollow body, producing the musical tones. Adjusting the player’s fingers over the holes along the flute alters the length of the vibrating air column, creating different notes.
