A short course built around five engines — the underlying patterns that produce almost everything you need to know at Grade 4 level. No lists. No memorisation by rote. Just the machinery behind the music.

Most introductions to music theory ask you to memorise facts one at a time — this key has that many sharps, this chord has those notes, this time signature means this. The list gets long quickly, and for many people it simply does not stick.
This course takes a different approach. It teaches the small number of underlying patterns — "engines" — that produce most of what Grade 4 theory covers. Once you understand why G major has F♯ (rather than just that it does), the key signature becomes something you can derive, not something you have to recall. That distinction matters enormously if memorisation is not your strong suit.
Music theory can seem daunting. But clarity is driven by five engines:
The five engines are not a list to learn in any order. They form a single chain, each idea built from the one before it — the spine of the whole course. Read it downward and each layer follows from the last.
The spine describes the pitch system: how notes relate to each other, how scales and keys are built, how chords arise from scales, and how notation captures it all. Time — how long notes last and when they happen — is a separate but parallel system that runs alongside pitch. The two together produce everything in a piece of music.
The keyboard gives notes; the gaps between them are intervals; a pattern of intervals is the major scale; numbering it gives degrees; a scale treated as home is a key; stacking degrees gives triads; the relationships between chords are harmonic function; functions punctuate as cadences; and cadences shape the phrases that build whole pieces.
This is not a performance course. It will not tell you how to practise scales, which fingering to use, or how to learn a new piece. It is the comprehension layer — the understanding that makes your practice time more efficient, but that practice time itself cannot substitute for.
It is also not a formal exam preparation course. The content covers everything a Grade 4 player is expected to understand, and uses Grade 4 vocabulary throughout. But the sequencing follows the logic of the subject rather than any exam syllabus, and there is no mock paper.
Understanding the engines gets you to Grade 4 comprehension. Grade 4 playing requires also putting time in at the piano. The two support each other — but neither replaces the other.
Pick the Learning Path that fits where you are now. Both paths cover everything from scratch through Grade 5 — the difference is the slope of arrival and the depth of early scaffolding. If you would rather be guided, the Quick placement check takes about two minutes and points you to one.
Select
1 Essentials Complete from scratch — the keyboard, all major and minor keys, chords, harmony, the stave and expression. Takes you to Grade 3 level. →Or
2 Advanced Builds on Essentials — intervals, harmonic function, modes, alt clefs, ornaments and more. Takes you to Grade 4–5 level. →You can switch Learning Paths at any point if the pace feels wrong.
Once you have worked through a Learning Path, a 20-question end-of-course test lets you check what has landed. It covers all five engine areas — four questions each — and gives a score per area, so you see precisely where any gaps remain rather than a single overall mark. It is always available from the menu, but there is no need to take it before you begin.
