Pandit Ravi Shankar (Bengali pronunciation: [ˈrobi ˈʃɔŋkor]; born Robindro Shaunkor Chowdhury, sometimes spelled as Ravindra Shankar Chowdhury; 7 April 1920 – 11 December 2012) was an Indian sitarist and composer. A sitar virtuoso, he became the world's best-known exponent of Indian classical music in the second half of the 20th century, and influenced many musicians in India and throughout the world. Shankar was awarded India's highest civilian honour, the Bharat Ratna, in 1999. He is also the father of American singer Norah Jones and British-American musician and sitar player Anoushka Shankar.

Shankar was born to a Bengali family in India, and spent his youth as a dancer touring India and Europe with the dance group of his brother Uday Shankar. At age 18, he gave up dancing to pursue a career in music, studying the sitar for seven years under court musician Allauddin Khan. After finishing his studies in 1944, Shankar worked as a composer, creating the music for the Apu Trilogy by Satyajit Ray, and was music director of All India Radio, New Delhi, from 1949 to 1956. He was nominated for the Academy Award for Best Original Score for scoring the blockbuster Gandhi (1982).

In 1956, Shankar began to tour Europe and America, playing Indian classical music and increased its popularity there in the 1960s through teaching, performance, and his association with violinist Yehudi Menuhin and Beatles guitarist George Harrison. His influence on Harrison helped popularize the use of Indian instruments in Western pop music in the latter half of the 1960s. Shankar engaged Western music by writing compositions for sitar and orchestra and toured the world in the 1970s and 1980s. From 1986 to 1992, he served as a nominated member of Rajya Sabha, the upper house of the Parliament of India. He continued to perform until the end of his life. He was a recipient of numerous prestigious musical accolades, including a Polar Music Prize and four Grammy Awards, including Album of the Year for The Concert for Bangladesh in 1973.

Shankar was born on 7 April 1920 in Benares (now Varanasi), then the capital of the princely state of the same name, in a Bengali Hindu family, as the youngest of seven brothers. His father, Shyam Shankar Chowdhury, was a Middle Temple barrister and scholar who was from Narail district, Bangladesh (then Jessore district in Bengal). A respected statesman, lawyer, and politician, he served for several years as dewan (Prime Minister) of Jhalawar State, Rajasthan, and used the Sanskrit spelling of the family name and removed its last part. Shyam was married to Hemangini Devi, who hailed from a small village named Nasrathpur in Mardah block of Ghazipur district, near Benares and her father was a prosperous landlord. Shyam later worked as a lawyer in London, England, and there he married a second time while Devi raised Shankar in Benares, and he did not meet his son until he was eight years old.

Shankar shortened the Sanskrit version of his first name, Ravindra, to Ravi, for "sun". Shankar had five siblings: Uday (who became a choreographer and dancer), Rajendra, Debendra and Bhupendra. Shankar attended the Bengalitola High School in Benares between 1927 and 1928.

At the age of 10, after spending his first decade in Benares, Shankar went to Paris with the dance group of his brother, choreographer Uday Shankar. By the age of 13 he had become a member of the group, accompanied its members on tour and learned to dance, and play various Indian instruments. Uday's dance group travelled Europe and the United States in the early to mid-1930s and Shankar learned French, discovered Western classical music, jazz, cinema and became acquainted with Western customs. Shankar heard Allauddin Khan – the lead musician at the court of the princely state of Maihar – play at a music conference in December 1934 in Calcutta, and Uday persuaded the Maharaja of Maihar H.H. Maharaja Brijnath Singh Judev in 1935 to allow Khan to become his group's soloist for a tour of Europe. Shankar was sporadically trained by Khan on tour, and Khan offered Shankar training to become a serious musician under the condition that he abandon touring and come to Maihar.

Shankar's parents had died by the time he returned from the Europe tour, and touring the West had become difficult because of political conflicts that would lead to World War II. Shankar gave up his dancing career in 1938 to go to Maihar and study Indian classical music as Khan's pupil, living with his family in the traditional gurukul system. Khan was a rigorous teacher and Shankar had training on sitar and surbahar, learned ragas and the musical styles dhrupad, dhamar, and khyal, and was taught the techniques of the instruments rudra veena, rubab, and sursingar. He often studied with Khan's children Ali Akbar Khan and Annapurna Devi. Shankar began to perform publicly on sitar in December 1939 and his debut performance was a jugalbandi (duet) with Ali Akbar Khan, who played the string instrument sarod.

Shankar completed his training in 1944. He moved to Mumbai and joined the Indian People's Theatre Association, for whom he composed music for ballets in 1945 and 1946, Dharti Ke Lal, 1946. Shankar recomposed the music for the popular song "Sare Jahan Se Achcha" at the age of 25. He began to record music for His Master's Voice and worked as a music director for All India Radio (AIR), New Delhi, from February 1949 until January 1956. Shankar founded the Indian National Orchestra at AIR and composed for it; in his compositions he combined Western and classical Indian instrumentation. Beginning in the mid-1950s he composed the music for the Apu Trilogy by Satyajit Ray, which became internationally acclaimed. He was music director for several Hindi movies including Godaan and Anuradha.
