The studies which take long time, and have hard, monotonuous process steps, begun to be made in the music field and spread among the teachers by the help of the computer thecnology. In this study, 50 Rast composition which are choosen randomly are analyzed by using computer thecnology to determine the usage of Rast maqam intervals.
