Edgar Aleksandrovich Arro was a Soviet Estonian composer. Born in Reval (now Tallinn) on 24 March 1911, he wrote operettas, cantatas, orchestral and chamber music, works for organ and piano, choral and vocal music, romances, and popular songs. He also used the pseudonym Enn Saluri.
Arro graduated from the Tallinn Conservatory in organ, studying with August Topman, in 1935, and completed its classical-composition course with Artur Kapp in 1939. From 1936 to 1940 he worked as an organist for Estonian Radio.
From 1944 he taught theoretical subjects at the Tallinn Conservatory and became a professor in 1972. Between 1948 and 1953, he led a seminar for beginning composers at the Estonian SSR Composers' Union. He received Estonian SSR State Prizes in 1948 and 1949 and was named People's Artist of the Estonian SSR in 1967.
His best-known songs include “Native City Tallinn,” “Song of Peace,” “Happiness,” “On the Hay,” “Song on the Swing,” “Hiking Memories,” and “In Pärnu Bay.” His stage works include the operettas Rummu Jüri (1954), written with Leo Normet, and Lights in the Home Harbour (1958), also with Normet. He composed music for theatre and films, including the musical films Melodies of the Baltic Sea (1960) and Chance Encounter (1961).
