Hanumatodi, more popularly known as Todi, (pronounced hanumatōdi and tōdi) is a rāgam in Carnatic music (musical scale of South Indian classical music). It is the 8th melakarta rāgam (parent scale) in the 72 melakarta rāgam system. This is sung very often in concerts. It is known to be a difficult rāgam to perform in owing to its complexity in prayoga (phrases of notes and intonation). It is called Janatodi in Muthuswami Dikshitar school of Carnatic music.
Todi in Carnatic music, is different from Todi (thaat) of Hindustani music (North Indian classical music). The equivalent of the Hindustani raga Todi in Carnatic music is Shubhapantuvarali (which is the 45th melakarta). The equivalent of Carnatic Todi in Hindustani is Bhairavi thaat.
