pitch-perfect

the term 'pitch-perfect' is a modern compound adjective, originating in the 20th century from the vocabulary of music and performance. its first element, 'pitch', derives from a middle english verb meaning to fix or set, which evolved to denote the specific frequency level of a musical sound. the second element, 'perfect', comes from the latin 'perfectus', conveying a state of completion and supreme excellence. when combined, the literal meaning "flawless in musical tone" was formed, and its usage broadened metaphorically to describe any action or detail executed with absolute precision and accuracy, perfectly hitting its intended mark.

Structure: pitch (musical tone) + perfect (flawless) pitch (from middle english 'picchen', meaning to thrust or fix; later developing the musical sense from the concept of fixing a note at a certain level. of uncertain origin, possibly old english). perfect (from latin 'perfectus', meaning completed or excellent, from 'perficere' - to finish, from 'per-' (thoroughly) + 'facere' (to do/make)).
