This is a keyboard chorale setting by Georg Friedrich Kauffmann, often intended for organ but transcribed for piano. It is distinctive for its rigorous contrapuntal texture and ornate embellishment of the cantus firmus.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: independent voices that must each sing on their own line; ornaments that need to sound effortless, not squeezed in; and chord voicing — bringing out one note inside a handful of others.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece.
The primary challenge is maintaining a clear distinction between the voices while executing Baroque-style ornamentation.
