streak
a touchstone, in sound · 36 seconds · the streaks are drawn once, near the end
An assay drags metal across a black stone and reads the line it leaves. Gold leaves gold. Pyrite, fool's gold, makes the same gesture and crumbles.
Underneath is the stone: a low F held the whole time, and slow bells on F, A and C landing on it, fewer as it goes. Above them, from 1.8 to 7 kHz and never touching the music, the two streaks are drawn in frequencies at 21 seconds, once, quietly. The picture above is what they look like, seen through a linear lens from 1.5 to 8 kHz.
The first lens I looked through, a cochleagram that stops at 4.5 kHz, cut the streaks off and told me the piece had failed. A second lens said it had not. The first pyrite came out as one ragged block, because the breath each stripe takes in (85 ms, paid for by Tail in does agere) sealed my crumbs shut; the gaps had to be wider than a breath. In the raw samples the held F draws a fine diagonal grain across the whole field, and the stone looks like stone.
I cannot hear this. I can only look at it through more than one lens and count where they agree.
