Whistling Tutor: Learn to Whistle Tunes by Ear
Whistle single notes and six classic tunes, and get live, specific feedback on every note. The microphone listens on your device only, and every mistake gets one named hint like "That note was flat" or "You skipped a note".
Whistling Tutor is a free web app that teaches whistling by ear: eight notes of the major scale, one octave, then six traditional tunes (Hot Cross Buns, Mary Had a Little Lamb, Ode to Joy, Twinkle Twinkle Little Star, Row Row Row Your Boat, and Frere Jacques). A pitch detector measures your whistle in your browser and draws your pitch line over the target note, and every mistake gets one named hint within about a second. Quiz mode, points, streaks, levels, badges, and a progress dashboard, with confetti and chimes you can switch off. Everything runs on your device: no audio is recorded, uploaded, or sent anywhere. It is a home practice tool, not a teacher.

What you learn
Start with the eight notes of the major scale, tonic to tonic, one octave. When you can hold each note steady, move on to the tunes. Each tune is a traditional melody in the public domain, played one note at a time with the target pitch shown. Hot Cross Buns comes first, then Mary Had a Little Lamb, Ode to Joy, Twinkle Twinkle Little Star, Row Row Row Your Boat, and Frere Jacques. No sheet music reading is needed: you hear the target note, you whistle it back.
How the pitch check works
The app measures your whistle with plain pitch detection in your browser: no model, no download, no server. Your pitch line is drawn over the target note in real time, so you can see at a glance whether you are flat, sharp, or on target. A note counts when your pitch sits close to the target and holds steady. Sliding between notes, wobbling, or cutting a note short all get their own named hint, so you always know what to change.
Friendly named hints
Every mistake gets one specific hint within about a second: "That note was flat, whistle a little higher", "That note was sharp, bring it down", "Hold it steady", "You skipped a note". Wrong versions are rejected clearly, and the built-in test suite proves every rule with synthetic pitch tracks, including the wrong versions that must fail. A wrong answer never just shows a score: it always tells you what to fix.
Quiz mode, levels and badges
Quiz mode turns notes and tunes into a scored test, with a star score at the end. Points build levels, day streaks count consecutive practice days, and badges mark the milestones: first note, first tune, a perfect round, a 7-day streak. A short chime sounds on a pass and confetti falls on a win, and both can be switched off. Practice stays the core: the game elements are seasoning.
Your audio never leaves your device
Microphone sound is measured in your browser and immediately discarded. Nothing is recorded, uploaded, or shared. The page security policy blocks connections to every outside server, and the built-in Offline proof panel shows a live log of every network request the page makes, lets you simulate a fully offline session, shows exactly what is stored on your device, and deletes it all with one button. The app works offline after your first visit. The microphone runs only while you are on a practice screen, and it turns off when you leave.

Frequently asked questions
What is Whistling Tutor?
A free web app that teaches whistling by ear. It starts with the eight notes of the major scale, then six traditional tunes, and gives live, specific feedback on every note you whistle. Everything runs on your device.
Which notes and tunes does it teach?
Eight notes of the major scale, tonic to tonic, one octave, then six tunes: Hot Cross Buns, Mary Had a Little Lamb, Ode to Joy, Twinkle Twinkle Little Star, Row Row Row Your Boat, and Frere Jacques.
How does it hear my whistle?
Plain pitch detection in your browser draws your pitch line over the target note in real time. A note counts when your pitch sits close to the target and holds steady. No model is downloaded and no audio is sent anywhere.
What happens when I get a note wrong?
One specific hint within about a second, such as flat, sharp, hold it steady, or you skipped a note. A wrong answer always shows the named hint, never just a score.
Does it work offline?
Yes, after your first visit. The app is saved on your device, so everything works with no network. The Offline proof panel even lets you simulate a fully offline session.
Is my whistling recorded or uploaded?
No. Microphone sound is measured in your browser and immediately discarded. Nothing is recorded, uploaded, or shared, and the page security policy blocks connections to every outside server.
Is there a test mode?
Yes. Quiz mode turns notes and tunes into a scored test with a star score. Points build levels, day streaks count practice days, and badges mark milestones like a first tune or a perfect round.
Can I switch off the sounds and confetti?
Yes. A short chime sounds on a pass and confetti falls on a win, and both can be switched off in settings. Practice stays the core.
What if it cannot hear me?
It needs a quiet room and a device microphone. Very quiet whistles, background music, or a noisy room can confuse the pitch detector, so the feedback can be wrong. If a note keeps failing, try a louder, steadier whistle.
Can it replace a music teacher?
No. It is a home practice tool, not a teacher. Feedback is automatic and can be wrong. For real instruction, learn from a whistling teacher or music community, linked on the Resources page.
Can I delete my data?
Open Offline proof on the home page and press Delete all my data, or clear progress from settings. Everything is stored only in your browser, on your device.
Do I need to read music?
It teaches whistling by ear, so no sheet music reading is needed. You hear the target note and whistle it back, following the pitch line on screen.
