Pitch strategy behind learning absolute pitch?
 

Not sure which forum to post this, so I'll ask the writers. :)

As I'm using the piano to identify pitch, I'm wondering what the industry consensus is for learning keys?

Meaning, within your vocal range, do you learn to identify all white keys first, then slowly integrate the accidentals?

Or do you integrate the accidentals as you increase your range, i.e.
Lesson 1 is C3 - D3,
then lesson 2 is C3 - C3# - D3, etc.

Not sure. I've always just listened and matched. Basically like someone speaking a word and you repeating it. As far as knowing which actual note it is, pshh, I have no clue. So far, it has never been a necessity when all you have to do is hear what you're supposed to do and replicate it.

From a writer's perspective, I see what you're saying.
I'm heading in the singing direction, so I see how my requirement would be different.

It's really up to you, I'm no professional vocalist, but I just try and pick up notes as they come to me in songs. Learning all the natural notes first would be useful as you can use that as I kind of a frame work for moving onto the sharps/flats
