Focus
“When the key changes, the chord names change — but the numbers do not.”
Decode
- 01Core patterns: 1–4–5–1, 1–5–6–4, 6–4–1–5, 2–5–1, 1–6–2–5–1.
- 02Converting each pattern into chord names.
- 03Transposing the same pattern across C, G, F, D and Bb.
Key Idea
Numbers are fixed. Names are relative to the key.
- Learn the number pattern once, then transpose it everywhere.
Practise Now
- 01Choose one progression pattern and transpose it into two new keys.
- 02Say the chord names aloud before playing each key.
What you should be able to do
You can convert a numbered progression into chord names and transpose it into new keys on demand.
