Born in Alwar, Rajasthan in 1927 into the illustrious Dagar family, Ustad Rahim Fahimuddin Khan Dagar is the son of Padma Bhushan Ustad Allabande Rahimuddin Khan Dagar who died in 1975. Initiated into the art of dhrupad at the age of five by his uncle Ustad Nasiruddin Khan Dagar, he received musical education for a period of 35 years from his father and family elders. In his words, “this included full mastery over the 52 alankaars (fundamental principles), Nada Yoga, Rudra Veena, Sanskrit education and of course Dhrupad-Dhamar.” He studied Rudra Veena from his uncle Ustad Ziauddin Khan Dagar for twelve years. He also took occasional lessons from his other uncles Ustad Hussainuddin Khan Dagar( better known as Tansen Pandey) and Ustad Imamuddin Khan Dagar. He learnt Sanskrit from his father and Pt. Giridharilal Shastri.
Ustad Rahim Fahimuddin Khan Dagar is known not only for the power and spontaneity of his alaap, but also for his rich repertoire of compositions, some of which are believed to date back to the 12th and 13th centuries.As he likes to put it about Dhrupad, "In the words of my ancestor Shat Shastri Baba Behram Khan Dagar, Dhrupad, as presented within our Dagar bani, is ‘ragatmak-swaratmak, shabdatmak-varnatmak, talatmak-layatmak and rasatmak. The singer has to portray its kalatmak, vidyatmak and adhyatmak aspects to do proper justice to it."
It is the quality of music which has taken him to many countries like the USA, France, Germany and Italy for performances before select audiences. His recordings have been released in Switzerland, Germany and Italy.
