perfect pitch is rare. it isn’t trainable. most people deep in music know this. u drop a ball on the piano and it hits 6 notes and the person tells u the pitches. you break glass on the ground and they tell you those pitches too. Meanwhile people with trained pitch can do somewhat decently with enough training and certainly someone playing an instrument long enough will just know which notes are being played on that instrument but it isn’t the same thing. absolute pitch is RNG even among music students.
