Uppalapu Srinivas (28 February 1969 – 19 September 2014) was a virtuoso Indian mandolin maestro and composer belonging to the classical Carnatic musical tradition.
 Srinivas was one of the most globally beloved South Indian musicians and is regarded as the Mozart of classical Indian music."
 Over his career, he toured across the world, and collaborated with John McLaughlin, Michael Nyman, and Michael Brook.
 At a very young age he was internationally viewed as the successor to Pandit Ravi Shankar.
John Barham is an English classical pianist, composer, arranger, producer and educator.
 He is best known for his orchestration of George Harrison albums such as "All Things Must Pass" (1970) and for his association with Indian sitar maestro Ravi Shankar.
 Barham trained at the Royal College of Music and the School of Oriental and African Studies in London, before establishing himself during the mid 1960s as a composer of piano interpretations of Indian classical ragas.
 He became a student of Shankar, for whose East–West collaborations with Yehudi Menuhin and others he transcribed Indian melodies into Western musical annotation.
 Through Shankar, Barham began a long friendship with Harrison in 1966, then a member of the Beatles, which assisted Harrison's own education in Indian music as well as his promotion of the genre to Western audiences.
 Barham collaborated with Harrison on the latter's "Wonderwall Music" soundtrack album (1968), before providing the orchestral arrangements for "All Things Must Pass" songs such as "Isn't It a Pity" and "My Sweet Lord", and for Harrison's 1973 album "Living in the Material World".
Janya ragas are Carnatic music ragas derived from the fundamental set of 72 ragas called "Melakarta" ragas, by the permutation and combination of the various ascending and descending notes.
 The process of deriving janya ragas from the parent "melakartas" is complex and leads to an open mathematical possibility of around thirty thousand ragas.
 Though limited by the necessity of the existence of individual "swaroopas" (unique identities) for the "janya" ragas, a list is never comprehensive or exhaustive.
 Thus the list below is open to additions or corrections.
 Moreover, some musicians experiment and use new scales, leading to new "janya" ragas.
 The 72 "Melakarta" ragas are numbered according to the ancient Indian system for numerical notation — the "Katapayadi system".
Shye Ben Tzur (שי בן צור) is an Israeli composer/producer/poet and performer who lives in India and Israel.
 He composes Qawwalis, instrumental and devotional music in Hebrew, Urdu and Hindi.
 Ben Tzur has been living and creating music in India and Israel for over a decade.
 He first visited India while searching for a classical Indian music teacher.
 After years of studying Indian classical music in the traditional manner, Ben Tzur began to compose traditional Sufi Qawwali music in his own language, Hebrew.
 Qawwali is a form of ecstatic devotional music.
Sangita (Devanagari: संगीत , IAST: saṃgīta ), also spelled Samgita or Sangeeta, refers to "music and associated performance arts" in the Indian traditions.
 According to Guy Beck, the root "saṃ-" implies "combining, coming together, convergent wholesome blending, unison" in the context of musical arts.
 "Sangita" connotes any form of singing with music, harmonious recitation or chorus singing in particular.
 In some medieval era literary genre such as the Puranas and poetic texts such as "Kathasaritsagar", a related term "Sangita-shastra" and "Sangita-vidya" mean the "art, science or knowledge of singing and dancing with music".
 According to Alison Arnold and Bruno Nettl, the modern term music fails to capture the historic sense of "Sanskrit "sangita" and Greek "mousike"".
 In the Indian tradition, the term "sangita" includes melodious singing, rhythmic dancing, instrumental music, classical, provincial, ritual chanting and incidental forms of music-related performance arts.
A raga (IAST: rāga; also raag or ragam; literally "coloring, tingeing, dyeing" ) is akin to a melodic mode in Indian classical music.
 While the "raga" is a remarkable and central feature of classical Indian music tradition, it has no direct translation to concepts in the classical European music tradition.
 Each "raga" is an array of melodic structures with musical motifs, considered in the Indian tradition to have the ability to "color the mind" and affect the emotions of the audience.
Improvisations is a 1962 LP album by Ravi Shankar.
 The opening piece is based on music from Shankar's score for Satyajit Ray's 1955 movie "Pather Panchali" with flutist Bud Shank playing in Indian style.
 Shankar composed "Fire Night" influenced by the 1961 Los Angeles fires and the song features jazz musicians Shank (flute) and Gary Peacock (bass) improvise over Indian percussion instruments.
 The concluding ragas are in classical Indian style: the first raga, Kirvani, with South Indian origin, and the second, Rageshri, with North Indian origin.
 The album was released in CD format by Angel Records in 1999 and has been described as a "visionary recording" by AllMusic reviewer Heather Phares.
Mēḷakarta is a collection of fundamental ragas (musical scales) in Carnatic music (South Indian classical music).
 "Mēḷakarta" ragas are parent ragas (hence known as "janaka" ragas) from which other ragas may be generated.
 A "melakarta" raga is sometimes referred as "mela", "karta" or "sampurna" as well, though the latter term is inaccurate, as a "sampurna" raga need not be a "melakarta" (take the raga "Bhairavi," for example).
Dhrupad (Sanskrit: ध्रुपद) is a genre in Hindustani classical music.
 It is one of the oldest forms of compositions in the classical Indian music and a form that is also found in its Carnatic tradition.
 It is a Sanskrit name, derived from the words "dhruva" (immovable, permanent) and "pad" (verse), a combination that means "pillar".
 The roots of Dhrupad are ancient, and it is discussed in the Hindu Sanskrit text "Natyashastra" (~200 BCE – 200 CE).
 It is also described in other ancient and medieval Sanskrit texts, such as chapter 33 of Book 10 in the "Bhagavata Purana" (~800–1000 CE), where the theories of music and devotional songs for Krishna are summarized.
