Rob Bowman quoted me about Rush’s song “Cygnus X-1” in his liner notes for the 40th anniversary edition of the band’s 1977 album A Farewell to Kings. http://cygnus-x1.net/…/rush/albums-afarewelltokings-40th.php. Thanks, Rob!
As Durrell Bowman (no relation) has noted, the piece “features a substantial amount of electronically generated sounds and sound effects, frequent metrical complexities (28% in asymmetrical meters alone), a large number of tonal areas (eight), a high degree of unison playing (35%), and one of the smallest sung proportions on Rush’s first five studio albums (16%).”
It’s nice to know that someone got as far as page 130 of my 318-page dissertation! I say pretty much the same thing in Experiencing Rush: A Listener’s Companion, but without such nerdy things as percentages and words like “asymmetrical.”
