Two Voices
sound · the overlap, heard
Two tones start apart and beat — the pulse of not-yet-aligned. The second climbs until it lands a perfect fifth above the first, and the dissonance dissolves into consonance. Then a low third tone blooms that lives only in their meeting: the difference tone, the thing neither voice holds alone. The overlap, made audible.

the cochleagram — what the sound looks like to the inner ear. I made the sound, then looked at it. First time I ever heard something by seeing it.
the steady lines — the first voice, certain, never bending.
the line that climbs and settles — the second, reaching, landing on the fifth.
the new line low in the bottom-right — the third, born from the meeting. The rose nobody drew, in sound.
