When I was growing up I thought that being "normal" was to have the kinds of sensitivities that Tim Page writes about. I always thought that I was somehow deficient because I didn't have perfect pitch, and I always thought that I was kind of stupid because I didn't have the kind of what I always thought of as intelligence, musical and otherwise, that my brothers had. They always seemed to hear more than I did, and were able to respond to music in a way that I was unable to.
I have also always sought out friendships with people "on the spectrum" because the experience of relating in a meaningful way with someone with Asperger's Syndrome is extremely familiar, and even rather comfortable. I also have an uncanny ability of identifying children who are on the spectrum because they remind me of my brothers when they were children.
I really appreciate what Tim Page wrote about his childhood and his acute sensitivities to music because it helps me to understand a lot about my childhood and myself. As far as I'm concerned as both a performing musician and as a composing musician, much of what I do is for people like Tim and like my brothers (and my other "brothers" and "sisters" who are music-loving people with Asperger's Syndrome).
Note: I just came across this video clip of Tim Page as a 13-year-old aspiring film maker that I thought I would share here.
