The Larynx: Vocal Folds part two

Last week we started looking at the vocal folds within the larynx. This week we’ll take a slightly closer look at the vibration that happens to create the sound of the voice.

We’ll be using a tuning fork as an example of how our vocal folds work.

Vocal folds: vibration

The vocal folds, also known as the vocal cords, vibrate super fast, depending on the pitch of the sound we make.

A tuning fork is a great example. My tuning fork is tuned to the note E and vibrates at 329.6 times per second. When it does that, it creates a hum. They’re vibrating so quickly, you can’t even see it happening.

Just like a tuning fork, our vocal folds are vibrating at a certain rate per second to create a certain pitch – they would be vibrating at 329.6 times per second, just like our tuning fork, if we wanted to sing the same E as the tuning fork.

You can appreciate that even just for an E at 329.6 times per second means your vocal folds are working really hard all the time when we are speaking and singing.

However unlike guitars, violins or even pianos, we can’t buy a new instrument when our old one starts getting a bit tired or bent out of shape! We only get one set of vocal folds so please look after them.

Next month we’re taking this idea of vibration creating pitch to another level when we look further into soundwaves and pitch!
