The term FLUTE PARTS can be broken down into two crossword solutions: STEMS (5 letters). The stem of a flute is the main body of the instrument, which is typically made of metal or wood. It is cylindrical in shape and has a series of holes along its length that are used to produce different notes. The other part of a flute is the head joint, which is the part that connects the stem to the mouthpiece. The head joint is usually made of metal or plastic and contains a series of keys that are used to change the pitch of the instrument.
