There is never any end. There are always new sounds to imagine; new feelings to get at. And always, there is the need to keep purifying these feelings and sounds so that we can really see what we’ve discovered in its pure state. So that we can see more and more clearly what we are. In that way, we can give to those who listen the essence, the best of what we are. But to do that at each stage, we have to keep on cleaning the mirror.
– John Coltrane
“The creation of something new is not accomplished by the intellect but by the play instinct acting from inner necessity. The creative mind plays with the objects it loves.”
Art is not just artistic but social and interpersonal; it is made by humans, for humans; it is expressive and communicative; and so we experience it also as these things
Amusia is a neurological disorder specifically involving music. An amusic cannot understand the pitch of the notes or distinguish one melody from another, he cannot understand when it is out of tune and when not, nor does he know how to notice the out of tune of the others - specifically, he cannot identify variations in pitch less than two semitones. In severe cases, they are unable to hear music or find it irritating and unpleasant, and would not be able to distinguish a chant from a national anthem or a symphony.
Citing a historical example, it seems that Che Guevara was unable to distinguish any musical genre. The description of these symptoms alone would seem to support the theory of musical specialization of a brain module.
Thomas Bever, professor of Cognitive Sciences and Neuroscience at the University of Arizona, has pointed out, since the 1970s, that music is "processed" by the right hemisphere in "ordinary" people, while in professional musicians (and experts of music) mainly the left hemisphere is activated.
