Online vocal trainer
The classic warm-up: up five notes of the major scale and back.
The trainer needs your microphone. The sound is analysed on this device and never uploaded.

Singing in tune is a skill you can train like any other – you just need to see what your voice is doing. The piano plays a phrase, you sing it back, and the pitch line shows where you landed: green on the note, amber close, red off. Each round climbs a semitone inside your range, and the summary tells you whether you tend to sing flat or sharp and which step of the scale gives you trouble.

How does the vocal trainer hear me?
Through your microphone, with the same pitch detector as the site’s tuner. The sound is analysed in your browser and never uploaded. For the best result sit in a quiet room about half a metre from the mic; headphones help in the sing-along mode, because then the mic hears only you.
What does the score mean?
It is the share of each note’s time you sang within the tolerance you chose – ±50 cents (a quarter tone) for beginners, ±35 for everyday practice, ±20 for a demanding ear. The first moment of every note is not counted, so a natural onset costs no points. Above 80 % is solid; the summary also shows whether you drift flat or sharp.
How do I find my voice type?
Open the Voice range tab: sing your lowest comfortable note, then your highest, holding each for half a second. The trainer shows your range on a keyboard and compares it with typical ranges from bass to soprano. Treat it as a starting point – a voice teacher also listens to timbre and where the voice changes register.
Can a man sing the exercises if they sound too high?
Yes. With “Accept any octave” on, the right note in any octave counts, so men can sing a high line an octave lower and women a low line an octave higher. Better still, measure your range first – the exercises then start in a key that suits you.
