About This Site

What is it?

HowToWhistle is a free browser app for practising whistling. Play along with songs from the library while a live pitch line shows every note you hit or miss. It also includes a whistling range test, daily challenges, and leaderboards—all free, no account required.

How to play

Open the site and allow microphone access (HTTPS required); headphones are recommended so the metronome does not leak into the mic
Pick a song from the library or try the daily challenge
Whistle along and watch whether your pitch line lands on the target notes
Never whistled before? Start with the range test to confirm the mic hears you, then read the beginner guide
Audio stays in your browser—recordings are never uploaded; leave a nickname only if you want to join the leaderboard
