Because you asked about the line between prose and poetry

Sparrows were feeding in a freezing drizzle
That while you watched turned into pieces of snow
Riding a gradient invisible
From silver aslant to random, white, and slow.

There came a moment that you couldn’t tell.
And then they clearly flew instead of fell.

Each drawing represents the production of one note. The solid line depicts the head just before the note begins and the dotten line depicts the head’s position at the end of the note. The solid horizontal lines serve as reference points to note the slight head lowering with each of the early notes.
