A Performance Grade involves a complete programme, so the work extends beyond correcting isolated notes. ABRSM’s expectations for Grades 4–5 include musical character, balance between parts and the stamina to sustain a performance. This makes the relationship between a melody and its accompaniment a useful Grade 4 practice focus.
For a piano example, imagine a melody being covered by its broken-chord accompaniment. The notes may be accurate, yet the listener hears the repeated accompaniment more clearly than the tune. Practising everything louder keeps the same problem.
Reduce the passage to this invented exercise in 4/4. Play four right-hand crotchets, G–A–B–C, above eight left-hand quavers, C–G–E–G–C–G–E–G, in a lower register. A crotchet lasts as long as two quavers. Play the right hand alone and sing its four-note line; then practise the left hand evenly at a softer volume. Combine them slowly, keeping two left-hand notes under each right-hand note.
Record the result and listen without watching your hands. Can you follow G–A–B–C easily while the accompaniment stays even? If the left hand gets louder whenever the right hand changes note, isolate that join and repeat it with the same balance. Return to the actual piece and follow its written phrasing and dynamics.
For another instrument, use a comparable passage from your own Grade 4 music with the tutor. Finish by playing the repaired passage in context and, later, in a complete programme run. Mark where musical shape or control fades as you tire, so the next practice session addresses a specific point.
