Focusing on the artistic heritage and historical journey of Hammâmî-zâde İsmâil Dede Efendi (1778–1845), one of the pole stars of Turkish music, this work examines the musical transformation handed down from the 18th to the 19th century through an aesthetic and musicological perspective. Analyzing Dede Efendi’s compositional style which blends "tradition" with the "spirit of the era" across a wide spectrum ranging from Mevlevi Whirling Dervish rituals (Ayins) to the lightest vocal forms in the light of archival documents, the study presents an in-depth portrait of the artist’s musical universe.
