Vocal Range Test Without a Microphone

How does the no-mic vocal range test work?

Maybe your laptop has no microphone, the browser won’t allow it, or you’re on a shared or school computer where it’s switched off. This page still finds your vocal range: instead of listening to you, it plays notes and you decide which ones you can sing.

1. Press “Play note” and sing along with the tone. The test starts on A3 (220 Hz). You can also tap any key on the keyboard, from C2 to C7.
2. Press “− Lower” to go down one semitone at a time, which is one piano key, white or black. Each press plays the new note. When you reach the last note you can still sing steadily and comfortably, press “This is my lowest note”.
3. Step 2 starts one octave above your lowest note. Press “Higher +” one note at a time (or “− Lower” if that start note already feels too high) and press “This is my highest note” on the last comfortable one. Changed your mind about the low note? Press “Redo lowest note”.

Your two notes then go through the same calculation as the microphone test: the number of semitones and octaves between them and the closest voice type. The tones are made in your browser with the Web Audio API, in equal temperament with A4 at 440 Hz.

How do I get a reliable result?

• Sing at a comfortable volume. Use your normal singing voice. Shouting a low note or pushing a high one does not count as part of your comfortable range.
• Warm up first. Hum or sing a few easy slides for a couple of minutes. A cold voice usually gives a smaller range than a warm one.
• Don’t strain. If a note scratches, cracks or makes your throat tight, the note before it is your limit. Stop there.
• Use headphones or speakers. You need to hear each note clearly to match it. Small phone or laptop speakers can make the lowest notes hard to hear.
• Test twice. Press “Try again” and repeat the test, ideally on another day as well. If you land on the same notes, you can trust them more.

How reliable is a result without a microphone?

It is only as reliable as your own ear and judgement. The page cannot hear you, so it cannot tell whether you matched the note, sang it slightly off, or sang it an octave higher or lower. That’s why the result card says “This result is based on the notes you marked yourself. It was not measured.”

Count a note only if you can sing it in tune, steadily and without strain. If you’re unsure about a note, leave it out: a slightly smaller range that you can actually use is more helpful than a big number. When you have a microphone, the vocal range test with a microphone measures the notes you sing. To compare your notes with every voice type, see the vocal range chart, or learn to find your vocal range by ear with a piano.
