I’m coming late to this, but I got a big kick out “In search of the click track“, a recent post on the new-ish blog Music Machinery. By analyzing slight variations in tempo via charts, it seems fairly straight-forward to determine which drummers are employing external cues to maintain a steady beat.
Blogger Paul Lamere starts by examining a track by a drummer who nobody believes used a click track, Ringo Starr:
Compare that to the pattern from a band so awful I wish they weren’t CanCon, Nickleback:
Pretty much indistinguishable from a drum machine. And I think I’d rather try to converse with a Roland DR-670 than with Daniel Adair.
This exercise serves a higher purpose than a game of gotcha. For instance, here is the pattern for John Bonham’s drumming in “Stairway to Heaven”, which slowly and imperceptibly builds intensity. Apparently Jimmy Page once said that the song “speeds up like an adrenaline flow” (note that downward slope indicates shorter beat durations, or a faster tempo).
A fun mystery (for me, anyway) posed in a follow-up post – is Neil Peart using a click-track on “The Enemy Within”, or does the analysis merely confirm the hypothesis that he is indeed a superhuman being from outer space?
