Sanam Marvi has been getting music training since the age of 7. She is from a Sindhi Family. Her father, Faqeer Ghulam Rasool, was also a Sindhi folk singer. Her initial classical music training, for 2 years, was from Ustad Fateh Ali Khan of Hyderabad, Sindh in the Gwalior gharana tradition. She says that she has also learned a lot from folk singer Abida Parveen.
Sanam Marvi debuted, in 2009, at ‘Virsa Heritage’, a music program on Pakistan Television Corporation channel hosted by Yousuf Salahuddin.
