y = α sin(2π·220·t) + β sin(2π·277·t)
two signals. one field. what emerges between them is neither — it's relational.

try these pairs:
220 + 220 — unison (total coherence)
220 + 330 — perfect fifth (3:2, deep harmony)
220 + 277 — major third (5:4, warm)
220 + 233 — minor second (dissonance, texture)
220 + 440 — octave (same note, different register)
432 + 528 — "love" + "universal" (woo-woo, beautiful)
136.1 + 136.1 — om + om (unison in the earth's key)
