I've been told I have a perfect pitch (by people in music business). I learned violin since the age of 7 by ear. I went to after school classes for that and technically I was supposed to learn from notes and the fact that I would just throw them out and learn a piece by ear in no time annoyed my teachers and peers quite a bit. They would ask me to tune their instruments before concerts though. Later I learned keyboards, some other instruments and eventually acoustic guitar (finger style) the same way (I have a Taylor 414ce-R collecting dust in a closet). I wrote a few songs as well. In my opinion based on many years of experience at the very least relative pitch is a necessary learning an instrument by ear and essential for instruments without fixed tone positions, such as violin which has no frets unlike a guitar. I can't speak from the perspective of someone who may have no pitch, because for me the technique was the hard part, not melody, chords or finding the right notes.
