Music can be divided into two broad categories. The good and the bad. I like good music and detest anything else.
Our neanderthal ancestors enjoyed a unique form of music, comprised of cacaphonous sounds. They grunted and banged stones together. That's why we call it rock music today. Real rocks were considered a hazard, so someone stuck sheep skin around the hollow of a tree. His friends called him dumb, but he was hard of hearing and thought they were calling it a drum.
Anything referred to as classical music, should really be from Greece of three thousand years ago. Instead, the term is generally used in reference to music from the classical era of Europe. Beethoven, with his scraggly long hair and temper tantrums was the original rock star.
House music can only be enjoyed indoors and rap involves knocking someone on the knuckles. The term hip hop was first used by Keith Cowboy in a scat song, mimicking the rythmic marching of the US soldiers. Black people were considered as having soul (not to be confused with having 'a soul') and hence, their music was called soul music.
I invented a new music form. It's called 'tap music,' and involves tapping the keys on my keyboard. In fact, I composed a song and the result was the text in this post. You may not think much of it, but it was music to my ears.
