I started with piano when I was 7. Briefly on Clarinet for a "while" a year or two later. My parents decided to stop Clarinet, because two instruments were too much for me.
I'll have to ask them about that.
All children are born with absolute pitch? So from birth, they can sing 12 tone equal temperament, a man made tuning system that, historically, is a recent development?
With all due respect, I know you're a Jazz historian, but I've been working with tuning systems, the harmonic series (aka Just Intonation) and microtones for 11 years and I'm not too sure this is true!
I've even heard radio programs where Johnny Reinhart of the American Festival of Microtonal Music in NYC demonstrating how children singing nursery rhymes are singing simple harmonic series intervals.
Joe G? Some thoughts?
