Grade 6 Theory extends beyond the earlier grades’ notation work. Its harmony content includes the dominant seventh in all inversions and the supertonic seventh in root position and first inversion. Tasks include writing chords in four parts or keyboard style over a given bass. Melody continuation and questions on scores need attention too.
A short harmony example in C major: take the notes B, D, F and G, with B as the lowest note. A common mistake is to call this a B chord because B is in the bass. Rearrange the notes in thirds: G–B–D–F. The root is G, the fifth note of C major, so the chord is the dominant seventh, often written V7. With B, its third, in the bass, it is in first inversion.
Now consider what two of those notes do when the harmony resolves to the tonic chord, C–E–G. B is the leading note and normally moves up to C; F is the seventh of the dominant chord and normally moves down to E. This explains two movements between parts. It is a starting point for a four-part answer: the remaining voices, spacing and movement between every pair of parts still need checking.
For follow-up practice, analyse F sharp–A–C–D with F sharp in the bass, in G major. Reordering gives D–F sharp–A–C: another dominant seventh in first inversion. F sharp normally rises to G and C falls to B on resolution. Explaining the key, root, inversion and note movements is more useful than memorising one shape. These are constructed teaching examples, not ABRSM questions or complete model answers.
For melody writing, mark the phrase’s destination before adding notes. Grade 6 continuation tasks can involve a move to a related key. The tutor should help the learner connect the new key, phrase ending and instrument range, then check whether the written melody actually carries out that plan.
