My "taxonomy" wasn't meant to be a perfect delineation, but just to show that there's lots of variations of tonal and harmonic recognition and recall. I agree

My "taxonomy" wasn't meant to be a perfect delineation, but just to show that there's lots of variations of tonal and harmonic recognition and recall. I agree that the way I phrased #4, sounded more like what you do in simple ear training exercises ("Is this chord a major or minor?"). But... when I watch, say, a video of Herbie Hancock copying another player's complex chord progression perfectly, there is clearly a harmonic+melodic version of "perfect pitch" for those few people who can hear music and reproduce it accurately.
