Q. Who composed the Sangita Ratnakara? Answer:
Sharangadeva
Notes: In the 13th century, Sharangadeva composed the Sangita Ratnakara, which has names such as the Turushka Todi ("Turkish Todi"), revealing an influx of ideas from Islamic culture. This text is the last to be mentioned by both the Carnatic and the Hindustani traditions and is often thought to date the divergence between the two.
