The origins of Indian classical music can be found in the Vedas, which are the oldest scriptures in the Hindu tradition. Indian classical music has also been significantly influenced by, or syncretised with, Indian folk music and Persian music. The Samaveda, one of the four Vedas, describes music at length. The Samaveda was derived from the Rigveda so that its hymns could be sung as Samagana; this style evolved into jatis and eventually into ragas. Bharat's Natyashastra was the first treatise laying down fundamental principles of dance, music, and drama.

Indian classical music is both elaborate and expressive. Like Western classical music, it divides the octave into 12 semitones of which the 7 basic notes are, in ascending tonal order, Sa Re Ga Ma Pa Dha Ni Sa for Hindustani music and Sa Ri Ga Ma Pa Dha Ni Sa for Carnatic music, similar to Western music's Do Re Mi Fa Sol La Si Do. However, Indian music uses just-intonation tuning, unlike most modern Western classical music, which uses the equal-temperament tuning system. Also, unlike modern Western classical music, Indian classical music places great emphasis on improvisation.

Classical music is the art music produced in, or rooted in, the traditions of Western liturgical and secular music, encompassing a broad period from roughly the 11th century to present times. The central norms of this tradition became codified between 1550 and 1900, which is known as the common practice period. It should not be confused with the Classical Era.

European music is largely distinguished from many other non-European and popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to prescribe to the performer the pitch, speed, meter, individual rhythms and exact execution of a piece of music. This leaves less room for practices such as improvisation and ad libitum ornamentation, that are frequently heard in non-European art music and popular music.

The term "classical music" did not appear until the early 19th century, in an attempt to "canonize" the period from Johann Sebastian Bach to Beethoven as a golden age. The earliest reference to "classical music" recorded by the Oxford English Dictionary is from about 1836.

Pandit Hariprasad Chaurasia (born 1 July 1938) is an Indian classical instrumentalist. He is a player of the bansuri, the Indian bamboo flute.

Hariprasad Chaurasia was born in Allahabad in the Indian state of Uttar Pradesh. His father was a wrestler. His mother died when he was 6.

He did go to the Akhada and train with his father for some time, although he also started learning music, and practising at his friend's house. He often credits his wrestling training for giving him the immense stamina and lung power that are the hallmarks of his flute playing, stating that,

Hariprasad Chaurasia started learning vocal music from his neighbor, Pandit Rajaram at the age of 15. Later, he switched to playing the flute under the tutelage of Pandit Bholanath Prasanna of Varanasi for eight years.

Anoushka Shankar (born 9 June 1981) is a British Indian sitar player and composer who lives between the United States, the United Kingdom, and India. She is the daughter of Indian sitar player Ravi Shankar and Sukanya Shankar. She is the paternal half-sister of Norah Jones.

Shankar was born in London and divided her childhood between London and Delhi. As a teenager, she lived in Encinitas, California and attended San Dieguito Academy. A 1999 Honors graduate, Shankar decided to pursue a career in music rather than attend college.

Anoushka married British director Joe Wright. Their first child, Zubin Shankar Wright, was born on 22 February 2011.

Shankar began training on the sitar with her father as a child, and gave her first public performance at the age of thirteen at Siri Fort in New Delhi. By the age of fourteen, she was accompanying her father at concerts around the world, and signed her first record contract, with Angel Records (EMI) at 16.

Though success came at an early age for Shankar, she was still uncertain if music was the career she wanted to fully pursue. "The question was continually back and forth in my mind," she admits. "After I graduated from high school, I made a decision not to go to college and start touring full-time. Even at that time, I thought maybe I’d do it for a year and see what happens. During that year, it became so clear to me that that was my life and who I was– a touring musician."
