The langeleik, also called langleik, is a Norwegian stringed folklore musical instrument, a droned zither.

The older Langeleik types were tuned after Pythagorean fashion, based on pure fifths and octaves, with variable smaller intervals.

When a note is wanted in between the basic rhythm, the index or middle finger needs to hammer-on or pull-off the melody string.

(See Polska) Valdres and Vardal are the only areas where the langeleik has a living (and thus more developed) tradition, with more melodies available, especially of the more recent, more complex kind, made for arguably better instruments.

The Telemark langeleik is distinct from the Valdres kind in that the sound-box is thin and straight-walled whereas the Valdres-langeleik curves to a broader lower part, and it does not have a board at the bottom and thus is more dependent on a good table for amplification.

The langeleik has had a renaissance, and while there are players in most part of Norway, there are not so many places -at least not well known- where the instrument is being played officially.

The types of tunes mostly played on the instrument are reinlender, vals, mazurka, gangar, springar and halling.
