I am not sure whether my following question belongs to this site. I want to ask you where is the point of this so called image macro with J. S. Bach. I am probably unwitty but I am not able to figure out its comic effect.
This joke depends on knowledge about music-- the joke itself isn't linguistic in nature. Basically, the joke is about J. S. Bach's tendency to use many voices in his work. The idea is that instead of simply transcribing the concerto from one instrument to another, he uses it as an opportunity to add even more voices to the piece.
