A work by J. Ph. Kirnberger (1821-1883), a pupil of J. S. Bach. It is preserved only in a document (P 636) held by the Berlin State Library. In the old complete edition, it is listed as 'old manuscript, composer's name not indicated'.

The whole piece is in strict three voices, with descending figures dominating the first half and ascending figures dominating the second half. While contrapuntal development and motivic work are handled simply yet carefully, the formulaic theme presentation and harmonic progression give it the feel of an etude. However, the melody, continuously passed between the left and right hands, is fluid and graceful, and filled with the transparent melancholy unique to A minor.
