the exotic. Numerous folk metal acts include a dedicated violinist in their line up. This includes Skyclad, Subway to Sally, Schandmaul, Mägo de Oz, Ithilien, Silent Stream of Godless Elegy, Korpiklaani, Lumsk, Elvenking, Eluveitie and Tuatha de Danann. The tin whistle and flute can be found in such Celtic metal bands as Cruachan, Waylander, Ithilien and Eluveitie. The flute can also be found in other bands such as Metsatöll, Schandmaul and Morgenstern. Medieval bagpipes are used in bands like Folkstone and In Extremo. Some bands are also known to highlight more exotic instruments from their ethnic background or country, including Skyforger's use of the Latvian kokles, Metsatöll's use of the Estonian torupill, Korpiklaani's use of the Finnish kantele, Eluveitie and Ithilien's use of the hurdy-gurdy, and Orphaned Land's use of the oud and saz.

Some of the sextets in the genre are Schandmaul, Cruachan, Korpiklaani, Turisas, and Midnattsol, while septets include Ithilien, Subway to Sally, In Extremo, and Lumsk. Both Silent Stream of Godless Elegy and Eluveitie boast eight members each while the line up of Mägo de Oz totals nine performers. Even when a band includes members dedicated to folk instruments, they might still rely on guest musicians to further enhance their sound. As an example, Lumsk added thirteen guest musicians to the band's seven members on their debut album Åsmund Frægdegjevar. At times, guest musicians are known to become full-fledged
