Shankar Jaikishan (also known as S-J), were a popular and successful Indian composer duo of the Hindi film industry, working together from 1949 to 1971. They are considered to be among the best composers of the Hindi film industry. Later, Shankar continued to function as a Music Director alone, still giving music under the banner Shankar-Jaikishan, till 1987. Shankar-Jaikishan, along with other artists, composed "everlasting" and "immortal melodies" in the 1950s, 1960s, and early 1960. Their best work was noted for being "raga-based and having both lilt and sonority".
