The white noise could be static or surf. The hum could be hushed vocals or a deep sine wave. The piece is “ãƒ‘ãƒ©ãƒ¬ãƒ«” — which I believe translates to parallel. It’s a track by Michiru Aoyama, who is based in Kamakura, Japan, and it is a blissful slice of determined ambient music. Tonally is is consistent and remote, the sort of thing that requires a fair amount of concentration to accept as foreground listening. What distinguishes it as a composition is how it unfolds, in particular a pause about a minute in and then again about a minute before the five-minute piece comes to a close. Both quiet moments remind the ear of the sonic content, waking you up to the atmospherics just as they get underway and just as they begin their slow fade to silence.
