Find a quiet space. Background noise makes pitch harder to detect. A normal room is fine — a noisy café is not.
Allow microphone access. Your browser will ask the first time you record. Nothing is uploaded or stored — the pitch detection runs entirely on your device.
Warm up first. Hum gently or run a few easy scales. Testing a cold voice gives you a narrower range than you actually have.
Record your lowest note. Press and hold the HOLD button on the “Lowest note” card and sing your lowest comfortable note on an open “ah”. Keep holding for the full six-second countdown — the note and frequency update live as you sing.
Record your highest note. Do the same on the “Highest note” card. As you sing, the keyboard fills in your range from your lowest note up to the note you’re on, so you can watch it grow.
Press “Analyse my range”. The button stays greyed out until both notes are captured. Your results appear a moment later.
Read your results. You’ll get your voice type, your range in notes, your span in octaves, four singers whose range most closely matches yours, and songs that sit inside your range.
Re-record any time. Hold either button again to replace that note — useful once you’re properly warmed up.

If you see “No stable pitch detected”, hold for the full six seconds, sing a single steady note rather than sliding between notes, and move a little closer to the mic. Humming works better than whispering.

What is a vocal range

Your vocal range is the distance between the lowest and highest notes you can sing clearly. It shows how high or low your voice naturally goes. This is one of the main ways singers are grouped into voice types like bass, tenor, alto, or soprano. Everyone’s range is different, and learning yours can help you sing more comfortably and with more confidence.

Why you should know your vocal range

When you know your vocal range, you can choose songs that match your voice. This helps you sound better and keeps your voice healthy. Singing within your natural range can reduce strain and make it easier to stay on pitch. It’s also helpful for joining choirs, taking singing lessons, or learning how to use your voice more effectively.

Voice types and typical ranges

There are six main voice types, each with a different range. These types help singers find where their voice fits best. Below is a simple guide:

Voice type	Typical range
Bass	E2 – E4
Baritone	A2 – A4
Tenor	C3 – C5
Alto	F3 – F5
Mezzo-soprano	A3 – A5
Soprano	C4 – C6

Here are the ranges of singers you'll know:

Freddie Mercury was a tenor
Adele is considered a mezzo-soprano
Johnny Cash sang in the bass range
Beyoncé is often classified as a soprano.

How the vocal range tool works

This tool uses your device’s microphone to listen to your voice in real time. You press and hold the buttons to sing your lowest and highest notes. The tool detects your pitch and calculates your full vocal range. It then compares your range to standard voice types and shows you where your voice fits. Everything runs directly in your browser. There’s nothing to download, and nothing is saved or recorded.

Tips for best results

For the most accurate results, make sure you're in a quiet room without background noise. Use headphones if you can, and warm up your voice with some light humming or simple scales. Don’t try to force your voice to go lower or higher than feels natural. Just sing clearly and steadily. If your result doesn’t feel right, you can always try again.

What to do with your vocal range

Once you know your range, you can use it to choose better songs and sing with more confidence. It also helps if you're auditioning, joining a choir, or working with a vocal coach. Knowing your range lets you work on improving your technique and expanding your range over time. You’ll also avoid straining your voice by singing in the wrong key.
