How does a recorder make noise?

Answer 1

A recorder is a musical instrument that produces sound through the vibration of air. Here's how it works:

Windway and Mouthpiece: The recorder has a narrow tube with a specific shape known as the windway. At the top of the recorder, there's a mouthpiece where the player blows air.

Air Vibration: When you blow air into the mouthpiece, the air is directed through the windway. The shape and design of the windway cause the air to split and rejoin, creating an area of low pressure.

Edge Tone Production: As the air flows over the edge of a sharp edge within the windway (called the labium), it causes the air to vibrate and create sound. This vibration is the initial sound source.

Resonance: The vibrating air inside the recorder's body interacts with the volume and shape of the instrument, generating specific resonant frequencies. The body of the recorder acts like a resonating chamber, amplifying and shaping the sound.

Finger Holes: By covering or uncovering the finger holes on the recorder, the player changes the effective length of the air column within the instrument. This alters the pitch of the produced sound.

By controlling the airflow, the position of the fingers on the holes, and the amount of air pressure applied, the player can produce different pitches and create music on the recorder.
