The Kazakhs themselves, however, did not write their own music in notation until 1931. Later, as part of the Soviet Union, Kazakh folk culture was encouraged in a sanitised manner designed to avoid political and social unrest. The result was a bland derivative of real Kazakh folk music. In 1920, Aleksandr Zatayevich, a Russian official, created major works of art music with melodies and other elements of Kazakh folk music. Beginning in 1928 and accelerating in the 1930s, he also adapted traditional Kazakh instruments for use in Russian-style ensembles, such as by increasing the number of frets and strings. Soon, these styles of modern orchestral playing became the only way for musicians to officially play; Kazakh folk was turned into patriotic, professional and socialist endeavours From Folklore to Soviet National Culture- The Process of Formation of "Kazak National Music"(1920-1942)-.
