“Nine Jewels” in Akbar’s court (navaratnas). The details of Tansen’s life
  are however, incomplete. He was born in a Hindu community and had his
  musical training under the great Swami Haridas. He then went to the court
  of the Raja Ram Baghela, a great patron of the arts. From there he
  migrated to the court of Akbar.
  It is said that Tansen could work miracles with his singing. He is supposed
  to have acquired such supernatural abilities called nada siddha through the
  association with the saintly Swami Haridas. It is said that on occasion he
  could create rain by singing the monsoon rag Megh Malhar. It is also said
  that he could create fire by singing rag Dipak. Many ragas are ascribed to
  Tansen and among them ragas such as Mian ki Malhar, Mian ki Todi and
  Darbari Kanada are most famous. Today his followers are referred to as
  “Senia Gharana”
The Mansab System
Meaning
Mansab (or rank) under the Mughals indicated the position of its holder
(mansabdar) in the official hierarchy. Apart from determining the status of its
holder, it also fixed his pay and the number of troops with horses and
equipment to be maintained by him. The mansab system under the Mughals
was a system in which the peerage, and the civil and military administrations
were all rolled into one complex whole. Under the system, mansabs (ranks)
in terms of numbers were assigned to nobles and commanders, who were also
placed in important administrative positions. Thus, the Mughal mansab
system included all public services (such as military, civil and financial),
except the judiciary.
