Samund Singh's first major performance came at the age of nine when he staged kirtan before a large gathering at a session of the Sikh Educational Conference. Soon he became the rage for Sikh divans throughout the Punjab. His training continued under his father and under other masters. He was quick at memorizing the holy word of the Gurus. Thus his range and repertoire from Gurbani were very wide. He learnt to play on string instruments such as the tans, dilrub5 and t5npura besides the harmonium and tabla. He acquired mastery of most of the thirty-one ragas in which Gurbani is composed. He excelled in Khayal, Thumarl Afng, Multani Ang, Dhrupad and Dhumar. He began to live and enjoy the Word he sang with exceptional ease and effect. His presence inspired veneration and his performance helped to create a devotional atmosphers.

Samund Singh was given employment at Gurdwara Janam Asthan at Nankana Sahib where he performed kirtan with his two companions, Teja Singh and Harnam Singh. He resigned from the position of head ragi after a few years, but continued to live in the holy city of Nankana. He travelled to the remotest corners of the country on invitations from Sikh societies and institutions to perform kirtan. He introduced Gurbani kirtan to Hindu and Muslim lovers of music and great artists, including Bare Ghulam 'Ali Khan. He was among the first Sikh musicians to broadcast kirtan from the Lahore station of All India Radio.
After the partition of 1947, he migrated to Amritsar and performed kirtan at the Golden Temple, later shifting to Ludhiana. He continued to command respect as the most accomplished Sikh musician. In 1970, he was given the Bhai Mardana Music Award by the Punjab Government at a state ceremony at Chandigarh. He gave on the occasion what turned out to be his last major performance. Samund Singh died at Ludhiana on 5 January 1972.
