2How sensitive should the suggestions be?
Not sure? Balanced is a good first draft. You can draft again at another sensitivity at any time; every draft is kept as a set of candidates to choose from, and nothing you have confirmed is changed.

Charts already worked out, so nobody has to do the same song twice. Open one, then open your own copy of the recording to play along with it.

Sections, bar lines and a chord sheet
Photograph one, or paste it — chords over lyrics, a list of bars, anything with chord names in it. The sheet's own key is worked out from its chords, so a sheet in G and a recording in B flat still line up: the chords are read as degrees and put back in the key being played. The detector is then told to look only for those chords.
A photograph is read here in this browser and never sent anywhere. The reader is about 9 MB and loads the first time you use it. It reads chord sheets — chord names over lyrics. It cannot read printed staff notation, and nothing honest can, yet.

chord, Next → goes to the next one to check. Or tap one of
the key's chords above the chart: it goes in to the end of the bar, and the
next bar is selected. Write
chords as G, Em7, D/F#, as numbers
(1, 6m) or - for no chord. Tap a tempo
to change it. Your draft is kept in this browser as you go.
Click a beat to play from there. Enter confirms the
suggestion there; 1–7 put in the key's chords
(0 for none) to the end of the bar and move to the next;
E or a double-click types over it
— in the box, Tab moves along, Enter fills
the rest of the bar, Esc gives up. Write chords as
G, Em7, Dsus4, D/F#
— or as numbers, 1, 6m, 5/7,
read in the key above — and - for no chord.
Click a tempo to change it; More → Add a tempo change puts one
at the bar you are on. If the bar lines slip after an odd bar, open
Sections, bar lines and a chord sheet below the chart.
