Name the numerals

Each round plays an unlabelled loop in C: diatonic roles, borrowed colors, and bright outsiders, all mixed. Feel each chord's role against home, then say its numbers. This is relative pitch: the real, learnable skill behind "playing by ear".

How to listen

Don't chase the pitches. Anchor home first, then ask of each chord: resting or leaning? Bright or dark? Inside the key or visiting? The numerals follow from the answers.
