Intelligence is also a talent.
Intelligence would probably enhance your understanding of the music (finding countermelodies and all) while talent is your ability as a musician (interpretation). From listening to Glenn Gould play; I would think he has no common sense.
Glenn Gould had no common sense?I'm glad he didn't have whatever you consider to be "common" sense.
Talent = f(Intelligence). f'(Intelligence) > 0Ceteris paribus, smarter pianists have more talent for the piano. But musicianship comes from elsewhere, like experience, musical culture, personality.
Talent = f(Intelligence). [Talent is a function of intelligence.] f'(Intelligence) > 0 [Talent is increasing in intelligence. Positive first derivative!]Ceteris paribus, [Everything else equal] smarter pianists have more talent for the piano.
To me, it seems there are thinkers and there are doers, musicians who think and analyze alot, and those who just go with the flow.
