Structure
high <elevated>pitch <tone>ed <adjective suffix>
Etymology

The word combines "high" (Old English hēah, meaning "tall" or "elevated") with "pitch" (Middle English picchen, from Old English piccean, meaning "to thrust" or "fix," later evolving to mean "musical tone" via the idea of "setting" a note's frequency). The suffix "-ed" turns the phrase into an adjective. Originally used literally for sounds, it later extended metaphorically to describe tense emotions or situations.
