This is a keyboard transcription of a concerto by Prince Johann Ernst. It is notable for its bright, idiomatic string-writing style and clear formal architecture.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: independent voices that must each sing on their own line; fine finger independence within the hand; and precise articulation — the difference between crisp and blurred is the piece.
Beyond that, expect ornaments that need to sound effortless, not squeezed in, and continuous sixteenth-note figuration that must ripple, not chatter.
Maintain clean articulation in the rapid passage work while balancing the two voices clearly.
