Did I Sing?

From A Well-Mannered Storm: The Glenn Gould Poems, published by Caitlin Press in 2008.

I hummed, I drummed
my feet, conducted
myself and anyone else
who’d pay attention, or not
whole carols, anthems, hymns
my body
a pulse and thrum
vibrating, pendulum
a rhythmic
throb and flutter
in a roll and pitch
see-sawing, a diving board its
upward oscillation a palpitation
the room a seismic
lurching all those pitching
microphones a-flutter
and I ask,
(an aside to the engineer
beside the tape recorder,
open-mouthed)

Did I sing?
