Låtfiol

The use of sympathetic strings makes the låtfiol more akin to the Norwegian national instrument, the hardingfele, also known as the Hardanger fiddle.

A låtfiol typically has a standard violin scroll rather than a carved lion head which is most common on hardanger fiddles and Swedish double-deckers.

[1] The use of sympathetic strings create extra resonance, atmosphere and volume while playing and is also used on Swedish keyed fiddles, such as the nyckelharpa and the related silverbasharpa.

The sympathetic strings are typically longer than the melody strings, and are connected to the furthest pegs atop the scroll, while they are strung underneath a heightened fingerboard, through a specialised bridge, and connected to small, modified fine-tuners (or hooks) on the tailpiece.

The latter is a difference from the Swedish double-decker where the sympathetic strings are attached to small metal pins on the ribs next to the end pin,[1] and is probably explained by the fact that the first maker of a Låtfiol was a Norwegian luthier who earlier built hardanger fiddles (where the sympathetic strings are always attached to the tailpiece).
