Ratatosk String Quartet was founded in 2014 in Oslo. Named after a communicative squirrel from Norse Mythology, the quartet is comprised of master students at the Norwegian Academy of Music. The members have diverse backgrounds from chamber music groups in Norway, Finland and England.

In its first year of existence, the quartet has delved into the 20th Century string quartet repertoire, as well as the cornerstones of the classical repertoire. In 2015 they have won the chamber music competition of the Norwegian Academy of Music, and performed in Casa da musica as part of the Harmos festival in Porto, Portugal. The quartet took part in the European Chamber Music Academy (ECMA) session in Oslo April 2015.
