MUSIC? PLAY ON!

This is the most exploited part of human culture since time immemorial, music. Shakespear said: " if music be the spice of life then play on".
When did music start? who cretred music? The Holy Book, also called the Bible says that amongst the Israealites, the sons of Kora were the first to be appointed as official musicans leading the whole nation of Israel in praise and worship of their God, Jehovah.
I notice that all nations have their own form of music which they pipe or churn out for virtually every occasion of their life. It doews not matter whether it is time for war, they have songs encouraging their warriors to be brave infront of their advancing enemies. For joyful occasions, songs of joy and happines are sung by the community. Be it a time for mourning, they have songs that befits the mournful occasion.
But then, once more I ask, where is the origin opf music? Who's invention is it? can somebody out there tell me?
Today we have such diversified types of music like, Rap, Jazz, Pop, Rock Gospel etc.
Who can really lay claim to the fact that he or she is the original creator or composer of music and song? PLease stand up and be counted. I rest my case.
I am excpecting you to bombard me with all useful information for me and my kids so that I may inform them froma viewpoint of surity and definite confidence.
