Piano chords, scales and keys

792 pages, one for every chord, scale and key PianoLabs plays — the notes, the formula, the fingering and the chords of each key, from the same engine that powers the app.

720 pages

Chords

Triads, sixths, sevenths, ninths, elevenths, thirteenths and the altered dominants on every root — each spelled by degree, with its formula, its notes and a keyboard diagram.

48 pages

Scales

The major scale and the natural, harmonic and melodic minors on twelve roots, with the step pattern and both hands' fingering over one octave.

24 pages

Keys

All 24 keys: the signature, the scale and its degrees, the seven diatonic chords with Roman numerals, the sevenths, the functions and the common progressions.

How these pages are made

Nothing here is typed in by hand. Every page is generated from the engine PianoLabs itself runs on: the chord library that spells each chord by scale degree (so a diminished seventh's seventh is a double flat, not the enharmonic natural), the fingering tables behind the Scale Library, and the Key Explorer's diatonic chords and progressions. What you read here is what the app plays.
