Ustad Siddique Ahmad Khan was born in Moradabad in 1914. He began his training in Sarangi and vocal music with his father late Ustad Rafique Ahmad khan. He studied Sarangi extensively for about 20 years with his maternal grandfather late Ustad Ghaseet Khan and Ustad Amman Khan.

Khansohab took up employment with Calcutta Radio in 1945 where he got the opportunity to accompany several stalwarts of vocal music, like Ustad Bade Ghulam Ali Khan, Pandit Omkarnath Thakur, Ustad Salamat and Nazakat Ali, and Aftab-e-Mausiqui Ustad Faiyazz Khan. All of them highly appreciated his music and urged him to stay in Calcutta.

However he resigned from the post after 2 years and returned to Moradabad. Hence after he was intermittently employed with the radio station at Ranchi and Guwahati, but mostly dedicated himself to training his children disciples and carrying on the legacy of the gharana. In around 1972, he moved to Delhi to stay with his son Ghulam Sabir Khan and performed extensively for All India Radio there. Here, he accompanied yet more maestros like Ustad Nisar Khan, Ustad Sarfaraj Khan, Ustad Sharafat Hussain Khan, and Taan Samrat Ustad Naseer Ahmad Khan.

Khansahab has composed many bandishes, taranas and thumris in various raags under the pen name ‘Sanam Piya’. He trained a large number of disciples, treating them like his own children. Though he did not receive any awards, he used to believe that his disciples are his true award. Indeed, his sons, grandsons and other disciples continue to carry forward the legacy of this musical genius.
