Ravi Shankar (Bengali: রবি শংকর; born Robindro Shaunkor Chowdhury on 7 April 1920), often referred to with the title Pandit, is an Indian musician and composer who plays the plucked string instrument sitar. He has been described as the most known contemporary Indian musician by Hans Neuhoff in Musik in Geschichte und Gegenwart.

Shankar was born in Varanasi and spent his youth touring Europe and India with the dance group of his brother Uday Shankar. He gave up dancing in 1938 to study sitar playing 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.

In 1956, he 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 George Harrison of The Beatles. Shankar engaged Western music by writing concerti for sitar and orchestra and toured the world in the 1970s and 1980s. From 1986 to 1992 he served as a nominated member of the upper chamber of the Parliament of India. Shankar was awarded India's highest civilian honor, the Bharat Ratna, in 1999, and received three Grammy Awards. He continues to perform in the 2000s, often with his daughter Anoushka.

Pierre Henri Marie Schaeffer (ⁱ/piːˈɛər ˈhɛnriː məˈriː ˈʃeɪfər/; 14 August 1910 – 19 August 1995) was a French composer, writer, broadcaster, engineer, musicologist and acoustician of the 20th century. His innovative work in both the sciences —particularly communications and acoustics— and the various arts of music, literature and radio presentation after the end of World War II, as well as his anti-nuclear activism and cultural criticism garnered him widespread recognition in his lifetime.

Amongst the vast range of works and projects he undertook, Schaeffer is most widely and currently recognized for his accomplishments in electronic and experimental music, at the core of which stands his role as the chief developer of a unique and early form of avant-garde music known as musique concrète. The genre emerged out of Europe from the utilization of new music technology developed in the post-Nazi Germany era, following the advance of electroacoustic and acousmatic music.

Schaeffer's writings (which include written and radio-narrated essays, biographies, short novels, a number of musical treatises and several plays) are often oriented towards his development of the genre, as well as the theoretics and philosophy of music in general.

Yehudi Menuhin, Baron Menuhin, OM, KBE (22 April 1916 – 12 March 1999) was an American violinist and conductor who spent most of his performing career in the United Kingdom. He was born to Russian Jewish parents in the United States, but became a citizen of Switzerland in 1970, and of the United Kingdom in 1985. He is often considered to be one of the greatest violinists of the 20th century.

Yehudi Menuhin was born in New York City, United States, to Bielorussian Jewish parents from what is now Belarus. His sisters were the concert pianist and human rights worker Hephzibah Menuhin and the pianist, painter, and poet Yaltah Menuhin. Through his father Moshe Menuhin, a former rabbinical student and anti-Zionist writer, Menuhin was descended from a distinguished rabbinical dynasty.

Menuhin began violin instruction at age four under violinist Sigmund Anker; his parents had wanted Louis Persinger to be his teacher, but Persinger refused. Menuhin displayed extraordinary talents at an early age. His first solo violin performance was at the age of seven with the San Francisco Symphony in 1923. Persinger then agreed to take Menuhin as a student. When the Menuhins went to Paris, Persinger suggested Yehudi go to his own teacher, Eugène Ysaÿe. He did have one lesson with Ysaÿe, but did not like his method or the fact that he was very old. Instead, he went to the Romanian composer and violinist George Enescu, after which he made several recordings with his sister Hephzibah. He was also a student of Adolf Busch. In 1929 he played in Berlin, under Bruno Walter's baton, three concerti by Bach, Brahms and Beethoven. In 1932 he recorded Edward Elgar's Violin Concerto in B minor for HMV in London, with the composer himself conducting, and between 1934 and 1936 he made the first integral recording of Johann Sebastian Bach's Sonatas and Partitas for Solo Violin.
