The idea of music that can “accommodate” multiple levels of attention without “enforcing” any one is the most precise definition I’ve found for the kind of music that helps me to work. As Eno says, it’s less “background music” than it is multilevel music, something that creates a perimeter if that’s what I want, but which doesn’t suffer from requiring my sustained attention. I don’t think of ambient music as a genre, except in the most vague way. It’s not a particular set of sounds; it’s more a practice of listening, of using music as a tool to induce a particular mental state. When it’s functioning, the music recedes, leaving a space for thought. And though I’m not aware of it, I’m still listening. I have a high tolerance for repetition, but kitsch and banality quickly begin to force themselves to the front of my mind. Clicking on a playlist titled lo–fi beats to relax/study to brings me little relaxation or sense of studiousness. Since I am also a degenerate record collector, this suits me fine.
