GRAMOPHONE (an invented word, formed on an inversion of "phonogram"; φωνή, sound, γράμμα, letter), an instrument for recording and reproducing sounds. It depends on the same general principles as the phonograph (q.v.), but it differs in certain details of construction, especially in having the sound record cut spirally on a flat disk instead of round a cylinder.
