How does genetics play a role in perfect pitch vs. relative pitch? Is it possible to train someone who had relative pitch from a very young age to develop perfect pitch? (aka absolute pitch)
It is possible to develop perfect pitch. I can identify any of the notes you would find on a keyboard (not quarter tones). I could not always do so, and both my dad and my sister are people who do not have perfect pitch. I didn't know what perfect pitch was until after I had started developing it. I have played music since I was five, but I started to develop my perfect pitch when my orchestra director asked the class to hum an A. I couldn't do it, and I didn't know how they did it, but I knew that I was going to memorize that A. I could already identify any of the open strings (C, G, D, A, E) before I knew what perfect pitch was, and five years later, I can identify all of the notes. I think that age matters, since it will be harder later on to develop perfect pitch, but I am proof that it is possible. There is a school of thought that believes that you have it or you don't - My high school AP music theory teacher thought I was just saying things. However, my professor (who I trust much more) says that more and more researchers believe in the development of perfect pitch.
