Light the burn
Clear a run of glowing picks to fill the Burn. Light it and every point counts double while the neck is on fire.
Duo
Two necks on one screen. Player 2 can take the bass part, you share one amp, and the joint score has its own board.

Leaderboard
The top ten on every house track, solo by difficulty and duo by joint score. Post from the results card after a run. The server replays every posted run from its key presses and keeps the score it gets, so a number typed in by hand never makes the board.
How to play
The picks
Picks slide down the neck toward the brass rail. Press a lane's key when its pick meets the jewel lamp. Two picks side by side are a chord: press both.
Easy uses the first three lanes, Medium four, Hard and Expert all five. Change keys in Settings.
Timing
Heat
The gauge is the amp's temperature. Hits warm it, misses cool it. Let it fall to the bottom and the valve blows, which ends the song. Turn on No-fail in Settings to play through anything.
Burn
Picks with an ember ring are a burn phrase. Hit every one in the phrase to add a quarter to the Burn meter. At half full, press Space (or tap the meter) to light it: every point counts double until it burns out.
Duo
Two players, one keyboard or one screen. Pick Duo on the setlist: each player gets a neck, and on house tracks player 2 can take the bass part. You share one amp, so the heat gauge rises and falls with both of you, and your scores add up to one joint score with its own board.
Player 2's keys. On a touch screen, each player plays their own side.
Stars
Stars measure your score against a perfect run without burn. A perfect run earns five; burn makes up for a few misses.
Your own songs
Fretburn charts a song from its sound: onsets for the notes, the beat for the grid, each note's pitch for its lane, so the same note tends to sit in the same lane. Songs with a clear beat chart best. If notes feel early or late on every song, use Calibrate in Settings.

Timing offset
If notes feel late on every song, the sound reaches you later than the picture. Calibrate measures it: tap along to eight clicks.
