    A look inside

    From Grade 5 to Grade 6: every degree

    You already know this from Grade 5

    A quick recap, so you can check nothing is rusty. At Grade 5 you learned:

    • Triads and their qualities: major, minor, diminished and augmented, measured by the 3rd and 5th above the root.
    • Chords I, II, IV and V in any key up to six sharps or flats, in root position and first and second inversion (b and c), with the figures 5 over 3, 6 over 3 and 6 over 4.
    • Perfect, plagal and imperfect cadences.
    • Every interval, including augmented and diminished ones.
    Grade 5: chords I, II, IV and V (here in G major)

    Grade 6 adds the other three degrees (III, VI and VII), the minor key in full, figures with accidentals, four-part writing and seventh chords. The first practice questions check the Grade 5 part.
