I'm curious as how it would work, since my mind doesn't work that way.
Is it something that you've acquired over time, or have you always done that? I do recall at some point last year or the year before, I was flicking through a music magazine and I recall reading about someone who also saw notes as colours, and different pitchings of a note would be a different shade or something like that. It was an odd form of perfect pitch.
Anyway, I think he was born being able to do that.
Oh... I honestly thought all perfect pitch was something like that.
It's always been like that for me, though interestingly, the colours for each note have changed subtly over time.
When I did VCE music melodic dictation was just a matter of transcribing colours into notes. I also have different colours for different chords. I suppose it also relates to feelings. A diminished triad is a threatening sort of red, for example, because I guess it sounds very ominous. Different inversions are different shades of the same colour.
Yeah like all perfect pitch, you're born with it.
