do you mean being able to match a tone? wether by tuning a guitar or being able to sing a long to a tone etc, or is it something different you speak of?
i was talking about how absolute pitch is commonly called 'perfect pitch' but i think it's misleading to call it that because that makes it sound like it means you are great with pitches, but absolute pitch is not quite that, it's actually a very specific skill where you can name the absolute frequency of notes, but it has nothing to do any notes' relation to each other. notes' relationships to each other is where 99% of the music happens. and it's possible to have wizard-like absolute pitch and still have no clue where to find the birthday song or jingle bells
