Every Personal Soundtrack is written in a key that fits your actual voice — not a generic pop range that just happens to sit well for a session singer. To do that, we need to know where your voice comfortably lives: not your shower-belting high note, not your just-woke-up low note, but the range you can actually hold.

That's what this step is for. Timbrica's free Vocal Range Finder listens through your microphone as you sing from your lowest note to your highest, then narrows in on your comfortable range. It takes about two minutes, there's nothing to install, and nothing to pay for.

You don't need to be a singer. This isn't a test you can fail — it's just measuring the physical range your voice can comfortably produce, the same way a tailor measures a shoulder before cutting a jacket. Once you have your result, copy it and paste it into the form. That's it — your song will be built around it from there.
