I played with a piano/trumpet player who had absolute pitch (perfect pitch).

She thought of everything in concert key, which meant when she read trumpet charts, she had problems getting her brain around the notation being off, and transposing it to the concert key notes she learned on her trumpet.

I played sax in guitar bands most of my life. While sax players in orchestras prefer Bb and Eb concert, I really like playing in E and A concert better. My fingers are happier in those keys.

BTW, if two musicians auditioned for my band and had equal musical and personality skills, except one could read music, and the other not, I'd choose the reader. Of course, two people are never that identical with that one exception.
