Piano Guides

A 6-step interactive guide covering the 12-note system, the musical alphabet, the 2–3 black key pattern, Middle C, and the full 88-key layout. Includes sound, a quiz, and deep-dive expanders.

11 structural patterns baked into the piano's design — the 2+3 rule, the 12-note loop, chord shapes, pentatonic black keys, the circle of fifths, interval fingerprints, and more. Interactive keyboards with audio throughout.

7 patterns that explain why diminished chords are one of the most powerful symmetry tricks in music — clock face, elevator, three families, inversions, dominant disguise, four resolutions, and the diminished scale. Interactive widgets with audio.

All 88 keys of a standard piano — 52 white and 36 black — spanning A0 to C8. Interactive keyboard diagram, octave numbering, Middle C, and the grand staff explained.

16 interactive memory techniques for piano theory — staff mnemonics, sharps/flats order, key signature shortcuts, chord shapes, circle of fifths, and the memory science behind why they work (forgetting curve, chunking, spaced repetition).

Every chord symbol decoded — root, quality, extensions, alterations, and slash chords. Includes an interactive parser that breaks down any chord symbol you type, plus a reference table of 20 essential chord symbols.
