IT'S TRUE!

Mian Tansen was born as Ramtanu Pandey. He was a prominent Hindustani classical music composer, musician, vocalist and also an instrumentalist who popularised and improved the plucked rabab (of Central Asian origin). He was among the Navaratnas (nine jewels) at the court of the Mughal Emperor Jalal ud-din Akbar. Akbar gave him the title Mian, an honorific, meaning learned man.
Several of his raga compositions have become the  mainstays of the Hindustani tradition, and these are often prefaced with Mian ki (“of the Mian”), like Mian ki Todi, Mian ki Malhar, Mian ki Mand, Mian ka Sarang; in addition he is the creator of major ragas like Darbari Kanada, Darbari Todi, and Rageshwari. Tansen also authored Sangeeta Sara and Rajmala which constitute important documents on music.
Legends abound about Tansen: He is believed to have brought down rain with his rendition of Raga Megh Malhar and set lamps alight with the legendary Raga Deepak.
