I, being a high schooler, am still developing as a musician (obviously).
But I've found that the more I play and listen to music (meaning all the
time) I have gradually acquired somewhat perfect pitch.  I think this has
helped me in my intonation (I'm a violinist) and in being able to play on
the fly, but that could just be another product of hard work and immersion
in music.
