[1] The official permission to establish Rūta was received on 25 September 1908 and the founding meeting took place on 11 January 1909.

[5] The society had a choir (about 50 members) which performed works by Lithuanian composers (Mikalojus Konstantinas Čiurlionis, Juozas Naujalis, Mikas Petrauskas, Česlovas Sasnauskas, Stasys Šimkus)[5] as well as foreign composers (Pyotr Ilyich Tchaikovsky, Robert Schumann, Jules Massenet).
It has survived and is preserved at the M. K. Čiurlionis National Art Museum[9] and commemorated by a fresco inside the former theater of Rūta.
