[PAR] [TLE] Psalmus Hungaricus (Kodály) [SEP] Psalmus Hungaricus, Op. 13, is a choral work for tenor, chorus and orchestra by Zoltán Kodály, composed in 1923.  The Psalmus was commissioned to celebrate the fiftieth anniversary of the unification of Buda and Pest, and Óbuda for a gala performance on 19 November 1923 along with the "Dance Suite" by Béla Bartók, and the "Festival Overture" by Ernő Dohnányi, who conducted the concert.  The work's first performance outside Hungary took place under Volkmar Andreae in Zurich on 18 June 1926.  This marked a turning-point in the international recognition of Kodály as a composer, beyond his renown as an ethnomusicologist and music educator.
