Four opening cards establish the quality rules. The remaining 86 cards practice 43 chords in both useful directions: * chord name → correctly spelled notes * spelled notes → chord name and quality #### Exact scope Every major and minor triad is included for C, D♭, D, E♭, E, F, F♯, G, A♭, A, B♭, and B. Diminished and augmented triads are included when correct root-position spelling needs no more than single accidentals. The five deliberate exclusions are D♭ diminished (A𝄫), E♭ diminished (B𝄫), A♭ diminished (E𝄫), F♯ augmented (C𝄪), and B augmented (F𝄪). This keeps the practical set focused without replacing correct letter spelling with enharmonic keyboard shortcuts. #### Learning order Major, minor, diminished, and augmented construction rules come first. The chord cards then mix spelling and identification across varied roots and qualities without a short repeated quality cycle. The two directions for any one chord stay at least seven unrelated cards apart, so one prompt doesn't give away its partner. #### Sources and provenance The quality definitions and interval symbols were checked against [Open Music Theory's triads chapter](https://viva.pressbooks.pub/openmusictheory/chapter/triads/). The chord spellings were derived independently from those interval rules and checked letter by letter. Common chord-spelling and chord-identification tools were reviewed only to confirm that both recall directions are useful study tasks. This is an independently authored, unofficial educational deck.
