 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.

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"".
