There are many pieces to a violin. One important piece is the bow; without a bow you can’t play. Some other important pieces of the violin are the strings, tuning pegs, and the fine tuners. These three all deal with what sound the violin is going to make, and if that sound sounds good or not. The third thing is the bridge; the bridge holds up the strings and creates a stopping point when playing to not play below it. Some other pieces are the peg box, neck, fingerboard, the waist, F holes, tailpiece, and the chinrest. There are some more but these are some of the important ones.
