Låtfiol, which means "singing fiddle" in Swedish, is a type of violin. It is made differently from regular violins and is often used in Scandinavian folk music. It has a longer neck and a bigger body than regular violins, so it can hold more strings. The strings are tuned differently than a regular violin, and the låtfiol is usually bowed with a special technique that allows the player to make a singing sound. This makes it perfect for playing Scandinavian folk music.
