My son who plays bass professionally has relative pitch which means he can determine a secondary note from hearing in his head an E note. The note is always E so he has to work his way up or down the scale to figure out the secondary note.This is probably developed.
Perfect pitch on the other hand seems to be a talent your born with because it's uncanny how Matar can tell you the pitch-note and frequency, sharp ,flat or natural immediately with no calculation.
