Two chords. Sixty seconds. One number.

The distance between knowing a song's chords and playing the song is almost always one change. Save the progression, isolate the change that keeps breaking, run the minute, write down how many you played cleanly.

Save the song

Type the chords in playing order. Capo and key belong to the song, so a copy in a friendlier key is one action rather than a rewrite.

2.0

Choose the change

Every neighbouring pair becomes a drill, including the loop from the last chord back to the first. Pick the one that keeps breaking.

3.0

Run the minute

Four beats of count-in, then sixty seconds. Add a pulse anywhere between 40 and 240 BPM if you want one. The screen stays awake while you play.

4.0

Count the clean ones

Only the changes you actually landed. Note how it felt, one to five. That number is the one to beat next time.

5.0

Read the trend

Every pair keeps its own history and its own chart. When a change goes stale, it turns up in the next five-minute routine on its own.
