Talk:Concerto for 2 Harpsichords in C major, BWV 1061 (Bach, Johann Sebastian)
Free public domain sheet music from IMSLP / Petrucci Music Library
I'm unaware of a movement called a Fugue in any other concerto. I find this unusual. Of course, Bach wrote "fugally" often, or nearly everywhere, but to have a formal Fugue with a title of Fugue seems rare. And quite a fugue it is!
