Ottoman music (Turkish: Osmanlı müziği) or Turkish classical music (Turkish: Klasik Türk musikisi, or more recently Türk sanat müziği, 'Turkish art music') is the tradition of classical music originating in the Ottoman Empire. Developed in the palace, major Ottoman cities, and Sufi lodges, it traditionally features a solo singer with a small to medium-sized instrumental ensemble.
A tradition of music that reached its golden age around the early 18th century, Ottoman music traces its roots back to the music of the Hellenic and Persianate world, a distinctive feature of which is the usage of a modal melodic system. This system, alternatively called makam, dastgah or echos, is a large and varied system of melodic material, defining both scales and melodic contour. In Ottoman music alone, more than 600 makams have been used so far, and out of these, at least 120 makams are in common use and formally defined. Rhythmically, Ottoman music uses the zaman and usûl systems, which determine time signatures and accents respectively. A wide variety of instruments has been used in Ottoman music, which include the turkish tanbur (lute), ney (end-blown reed flute), klasik kemençe (lyra), keman (violin), kanun (zither), and others.
