I vehemently disagree. that's like writing when you don't know how to read. Possible, but meaningless.

I can't read sheet music. The condition to understanding Bach's music on your own is to first understand sheet music. So to make his music you must read and understand his language. Is that music? It's subject to whoever interprets it. If we go nearly extinct what would be a more useful piece of evidence of what music is, Bach's Sheets or Madonna's "LIKE A VIRGIN" MTV special?
