Strange what Baremboim says about music. Isn’t music a language and, as such, having meaning, be it of subjective moods and feelings… or even reflections on life (but certainly not representing ideas… )
In Daniel Barenboim‘s Norton Lecture series (collected in his book, Music Quickens Time), he brings music into this sphere of the impossible:
I firmly believe that it is impossible to speak about music. There have been many definitions of music which have, in fact, merely described a subjective reaction to it. The only really precise and objective definition for me is by Ferruccio Busoni…who said that music is sonorous air. It says everything and nothing at the same time.
