interview with Ethan Iverson:
People worry about the metronome, “I’m not gonna move, I’m not gonna move!” because that means you are good. If you move, that means your time is bad. But Miles and them moved all over the place, and it was fucking awesome.
No one ever listens to a tune and says afterwards, “Man, they were at exactly the same tempo the whole time, how hip was that?” Who cares?
It was not just tempo, back in the day they didn’t care about tuning, either! Sharp and flat as hell, but the feeling was right.
Nowadays people care. It probably has something to do with double-edged sword of schooling and the wrong kind of teachers.
Obviously, tuning is good, keeping time is good! If you are ignorant to it, that’s a different thing.
