Hello! Bryce Alexander here

I'd say the main advantage is in the enjoyment of playing and listening to music, which then leads to improvement in my composition and imrov skills. Sometimes, I think you need to see music in the context of structure and intervals so there is no replacement for relative pitch. To me, relative pitch relates more to the academic side of music. When it comes to perfect pitch, I try not to be academic about it, I just enjoy it, it is more to do with the pure art of music. I can throw all the music theory I know out the window and compose in a more instinctive way, then I would make use of perfect pitch more than relative pitch. Having said that, there is a great deal of material on my website about the scientific (academic) theory of perfect pitch, but that's from the engineer side of me, not the musician.
