Say hello to Doré

Doré is the headphone-wearing pup behind DoReDog — perfect pitch, endless patience. He hears a melody once and plays it right back, by letters. Learning music, but make it feel like play.

Why DoReDog

Built for people who play by ear

A real, live player

Every piece plays right in your browser with a synthesized reverb-piano — no downloads, no plugins. Watch the playhead sweep and the keys glow as it goes.

Colour-coded octaves

Each octave has its own colour — pink, green, red, gold and blue — so your eye follows the melody effortlessly, on the page and on the keyboard.

Free & instant

No account, no paywall. Open a piece, press play, adjust the speed and start learning. It’s that simple — supported by unobtrusive ads.

The letter system

Lower case, UPPER case, dashes.

Lowercase letters are the white keys. UPPERCASE letters are the sharps (black keys). Dashes are silence or held time. Stacked letters play together as a chord.
