One pentatonic from start to finish, in a single position. When a chord shifts the song's colour, only the note worth adding lights up.

05FAQ
Questions, answered
Something else on your mind? Billing details are on the pricing page.
Do I need to know music theory?
No. Level 0 shows only the notes of the chord that’s playing — the shortest path to not hitting a wrong note. The theory is there when you want it, one level at a time.
Electric or acoustic?
Both. Everything is drawn for a six-string guitar in standard tuning, so it works the same on a Strat, a Les Paul or a steel-string acoustic.
What kind of songs work best?
Anything with a clear harmony: pop, rock, blues, folk, MPB, ballads. Dense jazz reharmonisations will push the detector hard — hence the fine print up top.
Is the analysis always right?
It’s a machine listening, so not always. Chords it isn’t sure about are marked with a dashed border and a "?", and you can always trust your ears over the screen.
How long does it take?
About half a minute for the key, tempo and chords, all on the same page.
What happens to my audio?
It’s stored privately in your account — only you can open it. It is used to analyse the track and play it back to you, nothing else.
Is it free?
You can try it for free: a free account breaks down one song in full, and the tuner, metronome, chord dictionary and scale explorer are free for good. Pro is $7.99 a month or $58.80 a year and breaks down 25 songs every month.
