How to Use These Progressions
Read the Roman numerals
Every chord shows its Roman numeral — the chord's position in the key. In C major, I is C, V is G, and vi is Am. Lowercase numerals mean minor, and the small ° marks a diminished chord. Because the numerals describe relationships instead of fixed notes, the same pattern keeps working when you move it to a new key.
Take it to your instrument
Each chord tile lists the notes it contains, so pianists can voice chords directly and guitarists can match familiar shapes. Play along at the tempo you set, or slow the tempo down while you learn the changes and bring it back up once your hands know the moves.
Make it yours
The generator gives you a starting point, not a rule. Swap any chord for another from the full key list, reorder the sequence, or borrow a whole alternative progression. If it sounds good when you play it, it is good — trust your ear over the theory.
