Find the Chord Formula: Reverse-Engineer the Chord

The short answer: Find the Chord Formula runs chord knowledge backwards — given a chord type, name its formula in scale degrees (min7 is 1-♭3-5-♭7). Points scale with speed. Knowing the formulas is what lets you build a chord in any key without memorizing each one.

What the game is

You are given a chord type and answer with its scale-degree formula. It is the mirror image of the chord-spelling games — instead of notes out, you produce the recipe itself.

What it teaches

• The scale-degree formula for each chord type.
• Chord DNA — the pattern that defines major vs minor vs dominant.
• The key to spelling chords in any key, not one at a time.

Why it's cool

The formula is the reusable recipe: learn a dozen of them and you can spell thousands of specific chords. This game drills the small set of patterns that generate all the rest.
