Aino (sometimes referred to as the Aino Symphony) is a single-movement symphonic poem for male choir and orchestra written in 1885 by the Finnish conductor and composer Robert Kajanus. The piece tells the tragic story of the eponymous heroine from the Kalevala, although the Finnish-language text—Ring, Kantele, Ring! (Soi, kannel, soi!)—sung by the male choir at the end of the symphonic poem is not from the literary epic but rather is by an anonymous author. Aino premiered on 28 February 1885 at a concert celebrating the fiftieth anniversary of the Kalevala.
