About this work
The motif of Invention No. 4 in D minor combines a small ornamented figure with a line that immediately continues. Its recognisable rhythm circulates between the hands and maintains continuous tension even when both voices temporarily appear to move together.
Ornaments belong to the motif’s shape and need to retain its direction. Locate imitations, harmonic changes and cadences that redistribute the dialogue. A voice can remain expressive with less volume when its articulation and phrase ending are clearly directed.
First isolate the opening figure in all its positions, using the same fingering whenever possible. Then practise one hand strongly and the other lightly before reversing roles. Keep the tempo calm enough for ornaments to speak without delaying the pulse; increase it only when both voices breathe independently.
