The term PHONOGRAPH PART refers to the components of a phonograph, which is an early device for playing recorded sound. The three-letter solution ARM is the part of the phonograph that holds the NEEDLE and moves it across the record. The seven-letter solution TONEARM is an ARM with a STYLUS at the end that is used to pick up sound vibrations from a record. The six-letter solution STYLUS is the pointed tip of the tone ARM that makes contact with the grooves of a record. The six-letter solution NEEDLE is the small, pointed object that is attached to the ARM and vibrates when it comes into contact with the grooves of a record.
