Children aged 2-6 successfully trained to acquire absolute pitch (2012)
I am a professional musician (bassoon player in a symphony orchestra). I can, if I practice it a couple of times a week, achieve and sustain perfect pitch.<p>I had no semblance of perfect pitch until I decided to practice it at age 24. Before that the only chance I had to guess a note was to put in in relation to my own voice.<p>Even though I don't practice this anymore (it isn't very useful), I still often just instinctively know what note I hear.
