I grew up thinking I had perfect pitch, after a youth choir director identified it and realized I could name all the notes from a random key played on the piano.
Later in life, though, I realized that sometimes my perfect pitch was... half a step off? And like the writer of the article, I was better at identifying notes from my primary instruments (in my case violin and piano) rather than from an instrument that had a much lower or higher register.
Side note: last year my family and I coded and launched Perfect Pitch Puzzle, a wordle-esque game that helps people without perfect pitch practice identifying notes by guessing the first six notes of a melody at a time. https://www.perfectpitchpuzzle.com/ New songs are still being added daily. Enjoy!
