"Billboard allows you to get a birds-eye view of the Billboard Hot 100 by
listening to all the #1 singles from 1958 through the millenium using a
technique I've been working on for a couple of years called time-lapse
phonography. The 857 songs used to m ake the piece are analyzed digitally
and a
spectral average is then derived from the entire song. Just as a long
camera
exposure will fuse motion into a single image, spectral averaging allows
us to
look at the average sonority of a piece of music, howe ver long, giving a
sort
of average timbre of a piece. This gives us a sense of the average key and
register of the song, as well as some clues about the production values
present
at the time the record was made; for example, the improvements in home ste
reo
equipment over the past fifty years, as well as the gradual replacement of
(relatively low-fidelity) AM radio with FM broadcasting has had an impact
on
how records are mixed.
