To add to this, one of the seemingly better examples i was shown was that most of us who like music have a handful of songs that we can hear perfectly. We don't realize it, but that's one foundational tool to find the relative pitch of something. Ie despite not having absolute perfect pitch, we know can accurately hear a variety of notes by just remembering a song, chorus, hook, etc. In doing so, we can figure out those notes and then use that to help determine the relative pitch of something else. Works better the more songs you know. It's also not advocating learning songs for this purpose, but rather using songs you already know. Songs you grew up with, etc. Anything you deeply know.
