Erkin, who composed his first works while a student in Paris, was productive as a composer throughout his career as a professor of music which he embarked in 1930 at the age of 24, or occasion appearing as a pianist to perform a concerto, on others as an accompanist or as an orchestra conductor to interpret his own works or operas. He also conducted the Conservatoire Student Orchestra at its periodic concerts and composed the "Sinfonietta", a work composed expressly to help instrumentalists overcome certain rhythmic and modal difficulties, peculiar to Turkish music.
