According to the German studio Finally one cannot understand music. One can be seduced by music, or simply enjoy it. But to understand it – that’s impossible. See their animation below.
The main idea reminds me of an interview Pierre Boulez once had on a French television station with a writer whose name I’ve forgotten. First music is a mystery, the writer told Boulez. Then, after studying it, everything becomes clear. But, finally, with the performance, it becomes a mystery again.
The central question, however, remains: can some knowledge about music enhance the enjoyment or is knowledge sometimes obstructing certain encounters with music? Or do both statements contain some kind of truth?
