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. --- Interactive version: https://toollantern.win/learn-whistling-tunes/
