Violin
Violin and fiddle are two names for the same instrument. It has four strings and a fingerboard that allows the player to push the strings down to shorten the length of the vibrating string to produce different notes. The open strings on a violin from lowest to highest are G-D-A-E.
Traditionally these instruments have been made of wood. Newer technologies have allowed them to be made as solid body instruments with pickups similar to an electric guitar. Some even act as controllers for synthetic sound sources. This results in performers playing an instrument that looks like a violin but produces the sound of a clarinet or tuba.
These instruments are usually played with a bow but can be played other ways for special effect. They can be played pizzicato (plucked) for a special effect. The bow can be bounced or the stick can be tapped on the strings for a different kind of sound.
Violins/fiddles can be found in symphony orchestras, bluegrass bands, country and western music, small string ensembles, and small jazz bands.
