About this tool
This left-hand-only chart for G Major keeps the same 5-4-3-2-1 descent from the tonic as C major, with the crossover landing on E — the black key F♯ simply takes the second finger a beat later, without disturbing the shape.
Seeing the left hand by itself makes it clear how little a single black key changes the crossing pattern — the fingers doing the work stay the same, only the notes underneath them shift.
Drill the left hand in isolation until the crossover onto E is as even as the right hand's, then bring the hands together using the right-hand-only chart or the full interactive tool.
Example. C major in the right hand for one octave shows the finger numbers 1 2 3 1 2 3 4 5. The default two-octave right hand continues 1 2 3 1 2 3 4 1 2 3 1 2 3 4 5.
Limit. Fingerings are the stored one-octave charts for major and the three minor forms, not a custom editorial fingering you type in. The octave control is only 1 or 2.
