Who this is for
Learners fluent with chords in a key and Roman numerals who want to move between keys. Already modulate with pivot chords? Test out on Day 5.
Best done after: Chord Progressions, Transposing & Capo. It is advice, not a rule: every lesson has short "rusty on…?" boxes for anything you skipped.
Why learn this
A piece that stays in one key can feel static. Modulation (changing key) gives a piece **journeys**: a new section feels like arriving somewhere. Classical music is built on it, and pop uses it for the lift of a final chorus.
Smooth modulation is not mysterious: it uses a short list of **closely related keys** and **pivot chords** that belong to both. Learn the list, learn the hinge, and you can modulate anywhere.
What you will be able to do
- Closely related keys
- Pivot chords between keys
- The dominant 7th as a signpost
- Direct (abrupt) modulation
- Modulating to minor keys
- Hearing and spotting a key change
The 5-day plan
- Closely related keys. Name the relative, dominant, subdominant and parallel keys of any key.
- Pivot chords. Find the chords two keys share and read them in each key.
- Confirming the new key. Use the dominant 7th of the new key to announce a modulation.
- Direct modulation and minor keys. Know the abrupt modulations and how to move between major and minor.
- Plan and hear a key change. Plan a modulation between any two keys and recognise one when you hear it.
How each session works
Every day follows the shape of a workout. It starts with a warm-up that reviews earlier days, then technique: a short, plain explanation with a small interactive tool to try it on. Then come the working sets, drills with instant feedback, and a finisher, a short test with a pass mark so you only build on things you can do. A cool-down recaps the day and previews the next.
Choose your split
The daily split is a session a day: done in a week. The easy split is a session every other day, with rest days between: two weeks, and a gentler pace. On your own pace there is no schedule. Nothing is ever locked, and you can change split at any time.

Frequently asked questions
What is modulation?
Changing key within a piece, so a different note becomes home. It is confirmed by a cadence in the new key, not just by using one note from it.
What is a pivot chord?
A chord that belongs to both keys, so it can be heard in the old key and then re-heard in the new one. Am is vi in C and ii in G, so it hinges C and G.
What are the closest keys?
The relative major or minor and the keys a fifth above and below (dominant and subdominant), plus their relatives. They share all or all but one note.
What is a "truck driver's modulation"?
An abrupt jump up a step (or half step) for the final chorus of a song, with no preparation. It uses energy instead of harmony.
How do I know I have really changed key?
A cadence (V–I) in the new key, and enough time spent there that the ear accepts it as home.
