Let's think about it for a moment...
Music of any kind is simply a series of sounds, tied together in a logical pattern that we call a song. I've always wondered, after looking at it that way, why it's such an ingrained part of our cultures, and how it came to be in first place? What is it that makes us react to it the way we do? Where did dancing come from? Just something weird I think about once in a while.
I asked where did dancing come from and got this?
By asking 'where did dancing come from' its like asking when did humans decide to move to a beat. This was way, way back. In the neolothic age. Humans have been dancing almost since they could walk. As an expression of happiness, anger, to help rain come and to praise gods. It has been a part of human culture from the beginning of humanity.
humans like music so much because it develops the mood that your in. Also it comforts you.
Music is said to alter mood of people. When someone is mad they tend to listin to music that is heavier then they normaly would. If someone is happy they will listen to something up beat. have you ever hear a song on the radio and been in a good mood but then you hear a song and felt sad? It is because your brain places that song with a sad time in your life.
This was the best I could come up with ....I too would love to know the answers to the questions asked here
