Attuned is formed from "at-" (meaning to) and "tune" (from Old French *ton*, meaning sound or tone) and the suffix "-ed" (indicating a state or condition). The word "attuned" means being in harmony or in a state of adjustment to a particular sound or situation.
Think of being 'to' a certain 'sound' or 'tone' — that's why attuned means being in harmony with something.
