The story

Picture a medieval cantor preparing to launch a hymn: he is not merely making noise, but placing his voice into a particular tone. That idea lies behind Medieval Latin intonare, “to sing according to tone,” built from in- and tonus, the word for tension or pitch. Tonus came from Greek τόνος, literally something stretched—an excellent image for a tightened string vibrating into music. By the late fourteenth century, English speakers had reshaped Old French entoner into entune and entone, eventually settling on intone. So when a lecturer intones a warning, the word still carries a faint memory of a singer stretching sound into the right pitch.
