Eduard Oja: Eduard Oja (January 17, 1905 in Palupõhja - April 16, 1950 in Tartu) was an Estonian composer, conductor, music teacher and critic.  His father was a forest warden.  Between 1919-1925 he studied at Tartu Teacher's College at Tartu University, where he met Eduard Tubin, and he also worked for some time as a school teacher.  He was not a particularly prolific composer, composing mainly orchestral and ensemble works and choral music.  He was however much appreciated during his lifetime, and received awards and acclaim for several of his works.  He also worked as a conductor, leading the Tartu Women's Singing Society’s Women's Choir between 1930 and 1934, as well as a teacher of music theory at Tartu Higher School of Music.  In addition, he was himself a practising violinist.  A number of his works such as the opera Oath Redeemed (Estonian: "Lunastatud vanne" ) and the choral work The Return Home (Estonian: "Kojuminek" ) have been lost, although the majority of his work has survived, and is valued in museums in Estonia today.  The Eduard Tubin Museum of Alatskivi Castle contains exhibits related to him and his fellow students under Heino Eller, known as the "Tartu school", such as Eduard Tubin, Alfred Karindi, Olav Roots and Karl Leichter.

Today, he is most known for his piece "Salvation is Created" as well as works such as "Do Not Reject Me in Old Age" (solo for basso profondo) and movements from various settings of the Divine Liturgy of St John Chrysostom.

Salvation is Created: Salvation is Created is an original choral work composed by Pavel Tchesnokov in 1912.  It was one of the very last sacred works he composed before he was forced to turn to secular arts by the Soviet government.  Although he never heard his own composition performed, his children had the opportunity to in the years following his death.  "Salvation is Created" was originally published in 1913 by J. Fischer and Bro.  but its popularity drove editors to produce many different versions in both Russian and English.  Scored for either six or eight voices (SATTBB or SSAATTBB), the work is a communion hymn based on a synodal Kievan chant melody and Psalm 74 (73 in the Greek version).  The original Russian text is as follows:

En saga: En saga (English translation: "A fairy tale" or "A saga") is a tone poem written by the Finnish composer Jean Sibelius in 1892.  After hearing Sibelius's choral work "Kullervo", the conductor Robert Kajanus encouraged Sibelius to compose a purely orchestral piece, which eventually transpired into this work.  The evolution of this work is rather vague, although it is known that in 1890–1891 Sibelius had begun composing an octet for strings, flute, and clarinet.  The octet evolved into a septet by September 1892, and had acquired the title "Ballet Scene" No. 2 by November of that year.  However, a letter to Adolf Paul dated 10 December 1892 stated that Sibelius had finished "the orchestral piece "En saga"".
