My inability to read is something that has kept me from a lot of opportunities over the decades. I've tried and tried, but there's something about reading music that seems so foreign and alien to me I can't "get" it, and I've tried over 38 years to be able to read it. In my primary band, our keyboardist sight reads and has her minor in music, our drummer teaches music and has his master's in it, and our guitarist also sight reads and teaches music.
Me? I'm the illiterate runt of the litter. When working up something new, everyone emails each other the sheet music they've written - I get a midi file and sometimes a tab. They sit around discussing inversions, modes, etc., while I play Angry Birds on my iPhone. Still, I've managed to hold my own with them for 7 years, but I wish I could read.
Back on topic: I can't imagine even seriously considering doing session work with my non-existent reading skills - or teaching formally (no theory knowledge here, either). I'm shocked that (apparently) Pino doesn't read. Wow.
