Traveling Sprinkler by Nicholson Baker:
I drove home and worked through the first few guitar lessons in GarageBand. I practiced chords until the tips of my fingers hurt terribly. You have no idea how sharp guitar strings are. I looked at my fingers and saw deep red grooves. Fortunately the string just missed the numb skin graft on my index finger, where I once cut it slicing bread.
I wanted to play minor chords immediately, but the cheerful, well-groomed instructor from GarageBand was sitting on his stool telling me how to play major chords. They always start you off with major keys even though minor is where you generally end up.
