Where

Question · Eridian chord · 어디

In the Eridian chord language from Andy Weir's Project Hail Mary, the concept where (어디) is spoken as a 3-note chord rather than spelled out letter by letter. Eridians communicate by sounding musical notes simultaneously, so “where” is heard as G4, C5, E5, played with a rising pitch, over 0.5 seconds.

How “where” sounds in Eridian

“where” is built from 3 notes — G4, C5, E5 (392.00, 523.25, 659.25 Hz) — sounded for 0.5 seconds. The chord rises in pitch as it plays — a contour this translator reserves for questions. It belongs to the question category, which collects question words and conversational responses. In English it covers where; in Korean it maps to 어디.
