For singers who don’t play piano
Plug in a keyboard, start a song and press keys in time. You keep the rhythm; Keylark picks the notes, every one of them from the chords it hears in the song.
Free to start. Works in Chrome or Edge on a computer. No keyboard? Your computer’s keys A to K play too.
A drawing, not a screenshot: you press the keys, Keylark picks the notes.

A 45-second look at Keylark
Three things to do, and none of them is learning the song.
Play it in a Chrome tab, such as on YouTube, open a song file such as an MP3, or try the built-in demo song.
Any MIDI keyboard will do. Without one, your computer’s keys A to K play.
You decide when a note sounds. Keylark decides which note, from the chords it hears: the left hand plays the bass and the right hand the chords.
Press harder and it is louder. Hold a key and the note is held. The rhythm is yours; Keylark only chooses the notes.
Keylark learns a song as it plays, so the second time through it already knows where it is going.
The first time through
Keylark listens as the song plays and picks your notes from the chords it hears. It is learning the song while you play.
It is least sure just after a chord changes. That is the weak spot of listening by ear, and it is why the second play exists.
Played again
Keylark kept the song’s chords and when they change, so it is ready for each one. Both hands get the full chords, with richer ones where it is sure of them.
A song file or the demo song is learned before it plays, so it starts that way.
Keep the rhythm with your hands and sing over it. Keylark is for anyone who needs to join in without time to learn the song.
Play along at home to the songs you sing, with chords under your fingers.
Open your own backing track and add live keys to it, without learning each song first.
Hear a song’s chords under your hands while you work on the voice.
Start the song, put your hands on the keys and play along.
Keylark doesn’t teach piano. If you want lessons, a piano course is the better place to start.
The left hand plays the bass and the right hand plays the chords.
Chords is for singing over. Solo is for a tune of your own.
A grand piano and an electric piano.
Send the notes to another program on your computer, and play its sounds instead.
Nothing you play or hear leaves your computer. Keylark keeps only the names and times of the chords it learned, in your browser, and you can forget any song in Your songs. There is no account and no advertising. Checking your licence sends Polar your key and a random name for your computer, and nothing else.
Polar sells Keylark and handles the VAT. The prices include it.

No. Your computer’s keys A to K play too. A MIDI keyboard gives you more keys, and a harder press sounds louder.
Yes, with your own backing track: open the song file and play along. YouTube’s own terms are for personal, non-commercial listening, so use a YouTube song for practice and a backing track for an audience.
The first time through, Keylark is working out the chords by ear, and it is weakest just after a change. Play the song again and it knows every change before it comes.
It does not work in Safari or Firefox, or on an iPad or a phone.
Bluetooth adds a delay, so your keys sound late. Keylark warns you when it hears one.
Plug in a MIDI keyboard, or play on your computer’s keys A to K.
