How does the air inside of a guitar's body
affect the sound?
Air is always important when it comes to musical instruments. For guitars, the air plays a crucial rule when it comes to producing low frequency. If you sing or play a note somewhere between F#2 and A2, you might be able to hear the air inside resonating. This is called "Helmholtz Resonance".
The Helmholtz Resonance is caused by the oscillation of the air at the sound hole. You can think of air as a spring, when it is compressed, it builds up pressure. If you put a mass on a spring, the spring will then start to oscillate and vibrate. The same concept applies to the air inside of a guitar's body.
