Wolfgang Amadeus Mozart ： Fugue (unfinished) in g-moll, K.401 (K6.375e)

This unfinished fugue is marked by the shading and tension of G minor, with the appeal of its contrapuntal writing at the forefront. The subject is passed from one voice to another, while imitation and overlapping lines shape the musical flow. As the number of voices increases, the texture and momentum intensify, inviting close attention to the interplay of the shorter motives. In performance, it is important to keep each vocal line clear, bring out the entries of the subject, and maintain a balance that avoids excessive heaviness. Since the work is unfinished, rather than attempting to overstate its conclusion, performers should preserve the tension of the surviving music and let it unfold naturally.
