I think perfect pitch, relative pitch, synesthesia, gifted writing, steady hand for drawing etc. don't make an artist.
Creativity, attitude, soul and mindset make an artist.
I developed that opinion after numerous examples.
I'll give you 2.
I have an incredible gift of drawing. My hand is very steady, and the pen simply glides over the paper, creating what I imagined almost effortlessly. But, the most drawings I ever did (serious, expressionist, creative drawings) is maybe 10. At most.
That's how many times I felt that I can channel myself to create something by drawing. That's it, no more.
With music, I do it all the time, but I don't even have a relative pitch, nor am I a synesthetic. (reference for those who don't know what it is
http://en.wikipedia.org/wiki/Synesthesia)
On the other hand, my girlfriend... She's something else. So contradictive to herself.
She is a synesthetic. She can see colors in her mind's eye when she thinks, hears or reads a word. She also sees/feels colors when a certain note is played, or a certain scale even. To her- Am is red. The word "piano" is white, and the word "bass" is brown. She has a voice of an angel, she can sing anything almost perfectly. BUT it takes time to master a song. Or she can sing with the vocalist, but on her own, she misses like 80% of the notes. She can tell if someone else is singing a cover of a song a third lower, per example. But she struggles with singing her own stuff, on her own, or even following a whole band! Not to mention her rhythmic confusion. She can't play nor sing in a given rhythm for the life of her. If I tell her to play a half note, a quarter note, a half note and then a whole note, she'll play 3 half notes and a whole note. It's ridiculous. About her pitch, I don't know, I think it's relative. I'll have to check that out. She can point to some pretty small nuisances though, it's incredible. See how strange it is? She had piano lessons for like 7 years, she can play some classical music, but it's all rehearsed a million times. She never broke that frame of tutored music. I don't think she ever played a chord progression on her own, experimenting with it, or a melody, anything.
So.... I don't consider her a musician. She has some skills and talents that some people would kill for. But she's not a musician.
You give me any instrument in the world and I'll start tinkering with it, figure out a few patterns, maybe even create a song with it.
She, a classically "trained" musician can't figure out playing basic guitar.
It doesn't matter if you have perfect pitch or not... Or any other talent. It's something else. I don't know what, soul, call it whatever you want, but it's something else that makes you a musician or any other form of artist.
