So what has happened to music in its original form, at the campfires of our neolithic forefathers? It has survived in folk music, simple but rich in melody and an inspiration to composers like Smetana and Bartók, just to mention a few. Folk music has bred a vulgar offspring in pop music and in its most rabid form rock, sprung from rhythm & blues, the music of the black people in America. Music, like all art, is a two-way street: messages are sent and they are received. Pop music is produced by likeminded musicians at a frequency which is easily received by 'the big public'. Taking a cue from the alphabet: only crude messages are understood, if you can read just the first three letters. Image, visual effect, gossip, idolatry in all forms combine to sell whatever there was of music. So this is where pop became commercial and less rewarding for those who can read the alphabet from a to z.
