Witnessing the last periods of the Ottoman Empire and the first years of the Republic, Muallim Ismail Hakki Bey, like some great composers in the history of Turkish music, made important works to ensure that these "makams" are not forgotten by producing new works from "makams" that he noticed were rarely used in his lifetime. This study aims to draw attention to the rarely used "makams" preferred by Muallim Ismail Hakki Bey, who composed works in many forms of Turkish music, and his works in the classical fasil completion tradition. The study is considered important in terms of revealing the composer's effort to transfer the cultural memory of music. In the study, document analysis was made using the literature review method and the works of Muallim Ismail Hakki Bey in the TRT (Turkish Radio and Television) Repertoire were examined. It has been determined that it mostly includes rarely used "makams" and it has been tried to determine the rate of use of these "makams" in the repertoire with numerical data. In addition, the classical fasil completion works in Muallim Ismail Hakki Bey's understanding of composition were mentioned and the efforts of the composer to preserve the connection between the past and the future were emphasized.
