The machine in your throat

You own a musical instrument worth more than any guitar, and you've never read its manual. Let's fix that in six minutes.

The three-part machine

Every sound you make uses three components:

1. The power source — your lungs. Air is the fuel. No moving air, no sound. (Try saying "ahh" while holding your breath.)

2. The vibrator — your vocal folds. Two small bands of tissue in your throat that the air passes between, making them flutter against each other hundreds of times per second. That flutter IS your voice.

3. The amplifier — your throat, mouth and nose. The buzzing from your folds is actually tiny and unimpressive. It becomes YOUR voice by echoing through the spaces above — throat shape, tongue position, open mouth. Change the spaces, change the sound.

Feel it work (30 seconds)

Do these right now:

1. 1Put your fingers flat on the front of your throat and hum. That buzz? Your vocal folds, live.
2. 2Keep humming and slide the note higher. Feel things tighten slightly? The folds are stretching — like tuning a guitar string tighter for a higher note.
3. 3Now hum with your mouth in an "oo" shape, then an "ah" shape, without stopping. Hear the colour change? Same string, different amplifier shape.

Congratulations — you just consciously operated all three parts, probably for the first time.

Why your recorded voice sounds "wrong"

The universal horror of hearing yourself on a recording has a physical explanation: when you speak, you hear yourself through the air AND through the bones of your skull, which add warmth and bass. A recording only captures the air part.

Here's the uncomfortable flip side: the recording is what everyone else hears. Your "weird" recorded voice is simply your voice. The good news: everyone feels this way, including professional singers, and the cringe fades with exposure. Which brings us to…

The single most powerful practice tool

Your phone's voice recorder. Free, always with you, and brutally honest.

Recording yourself is the fastest feedback loop in singing — the difference between practising with your eyes open versus shut. It will feel horrible for about two weeks. Do it anyway. Every future lesson assumes you are recording your exercises.
