Musicophilia

Bought Musicophilia to read on long transcontinental flights.. It's rather entertaining, got me interested in musical perception again.

I've always wondered, how would you know that what you're seeing/ hearing is the same as everyone else? Is there an absolute colour? Is what I perceive as red the same colour as what you consider red? A baby doesn't know an apple is red until someone tells him that it's red. Could the apple be triggering blue light receptors instead in the baby's eyes? And if so, will the baby grow up seeing things completely different from others but not knowing so? Everything red will be blue to him, but he would call it red and believe it to be red because that's what he's been taught. Are we all seeing colours differently?

Protect ur ears. People hear all sorts of weird things when their ears are damaged/ when they go partially deaf..

Have been addicted to music lately.. addicted and affected. THere are songs that make me happy and songs that melt me.. And horrible tuneless hip hop songs. Wonder what causes these reactions. when can i write a melty song?
