This is a keyboard concerto arrangement of Vivaldi's violin concerto by J.S. Bach. It is distinctive for its rigorous contrapuntal texture and transcription of idiomatic string writing into keyboard figurations.
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 continuous sixteenth-note figuration that must ripple, not chatter, and ornaments that need to sound effortless, not squeezed in.
Maintain clarity and rhythmic drive in the rapid sixteenth-note passages while executing precise articulation.
