A gånglåt is a category of Swedish traditional folk music; a fiddle tune in relaxed 44 or 24 meter.
Not to be referred to/or confused with a march when this is spoken of in Swedish in the traditional genre.
A gånglåt resembles a slow Irish reel in structure, with two (or, more rarely, three) 16-bar strains, each repeated twice, in the form AABB.
Often the second A and B differs slightly in the end compared to the first instance.
The Swedish folk fiddle repertoire contains hundreds of traditional tunes in this form.
