What piece of music did Købke attach one of his studies to?
One of Christen Købke’s studies stands apart from the others. It is drawn in perspective on squared paper and is compiled out of several smaller pieces and strips of paper. The pieces of paper have been glued together on a brownish sheet of paper; the back of a piece of staff paper.
But what piece of music is written on the paper? Who is the composer, and when was the music composed?
