They are also frequently used in genres of folk including country music and bluegrass music and in jazz.  Electric violins are used in some forms of rock music; further, the violin has come to be played in many non-Western music cultures, including Indian music and Iranian music.  The violin is sometimes informally called a fiddle, particularly in Irish traditional music and bluegrass, but this nickname is also used regardless of the type of music played on it.

Traditional examples of background music include music played at various social gatherings and music played in certain retail venues.  It is also common to employ background music in various electronic media including film, television, video games, and Internet videos such as video blogs.
