There have been many definitions of music which to my mind have only described a subjective reaction to it. The only really precise one to me is the one by Ferruccio Busoni, the great Italian pianist and composer, who said that music is sonorous air. It says everything and it says nothing. Of course, appropriate moment to quote Neitszche, who said that life without music would be a mistake.
And now we come to the first question – why? Why is music so important? Why is music something more than something very agreeable or exciting to listen to? Something that, through its sheer power, and eloquence, gives us formidable weapons to forget our existence and the chores of daily life. My contention is that this is of course possible, and is practised by millions of people who like to come home after a long day at the office, put their feet up, if possible have the luxury of somebody giving them a drink while they do that, and put on the record and forget all the problems of the day. But my contention is that music has another weapon that it delivers to us, if we want to take it, and that is one through which we can learn a lot about ourselves, about our society, about the human being, about politics, about society, about anything that you choose to do. I can only speak from that point of view in a very personal way, because I learn more about living from music than about how to make a living out of music.
