Choose your voice, a scale and an exercise. The piano plays it and climbs half a step at a time through your range; turn on the mic to see if you are in tune.

Frequently asked questions
How do I know my voice type?
Start with the one whose range feels closest and adjust the lowest and highest notes to what you reach without strain. Roughly: soprano C4–C6, mezzo-soprano A3–A5, alto F3–F5, tenor C3–C5, baritone A2–A4 and bass E2–E4. Voice type also depends on timbre and where your voice feels comfortable, so a teacher can refine it.
How does the exercise move?
It starts in the key you choose at the lowest octave that fits your range, then rises half a step each time until the highest note would leave your range, and comes back down (or only goes up, or repeats in the same key).
Why practice in modes like Lydian or Dorian?
Each mode has a different color. Singing them trains your ear and your tuning for melodies that are not plain major or minor, which is common in jazz, film music, rock and folk.
How does the microphone work?
It measures the pitch of your voice in real time (the YIN method, plain signal processing, no AI) and draws it over the notes: green when you are within 35 cents, orange when you are off. Use headphones so the mic does not hear the piano. Nothing is recorded or uploaded.
How long should I warm up?
Ten to fifteen minutes is a common routine: start with soft, low exercises (long notes, 5 notes), then arpeggios and wider scales. Stop if anything hurts and do not push the top of your range.
