Question: What Indian musician is the father of Brij Narayan and popularised the bowed instrument sarangi as a solo concert instrument?
Context: Ram Narayan (Hindi: राम नारायण ; IAST: Rām Nārāyaṇ , ] ; born 25 December 1927), often referred to with the title Pandit, is an Indian musician who popularised the bowed instrument sarangi as a solo concert instrument in Hindustani classical music and became the first internationally successful sarangi player. Sakha Rama Rao (Sakharam Rao) is an Indian musician credited with having re-introduced the south Indian chitravina (or "gotuvadyam") to the concert scene.  However, it was his father, Srinivasa Rao, who made the pioneering effort towards the reincarnation of the chitravina in modern times.  He was an ardent music lover and an amateur artiste himself.  He started experimenting with a slide on the tanpura (a four-stringed instrument, usually used as a reference drone in Indian music).  Sakha Rama Rao was drawn to this instrument since childhood.  He was able to perceive its tremendous potential to produce high-class music.  He re-designed this instrument as a fretless veena with its usual set of seven strings - four strings on the top and three in the side for drone and rhythm.  He put in arduous practice on this instrument and gave occasional performances.  Since he was not aware of the history of the instrument, he gave it a new name - gotuvadyam.  This is because, he used to casually refer to the slide as 'gotu'.  'Vadyam', in Sanskrit and many other Indian languages, means instrument.  Thus, 'gotuvadyam' was a literal name for an instrument played with a slide.  Several decades later, Ravikiran, along with a few other scholars, studied about the origins of the instrument and eventually restored the more traditional name, chitravina.  Sakha Rama Rao was a "musicians' musician" and trained many great artists like Gotuvadyam Narayana Iyengar and Semmangudi Srinivasa Iyer.  Soon there were several others who started performing on the chitravina (gotuvadyam). Brij Narayan Chakbast, also spelled, Brij Narain Chakbast, (Kashmiri: बृज नारायण चकबस्त , Urdu: برج نارائن چکبست‎ ) was an Urdu poet. The cello ( ; plural cellos or celli) or violoncello ( ; ] ) is a bowed, and sometimes plucked, string instrument with four strings tuned in perfect fifths.  The strings from low to high are generally tuned to C, G, D and A, an octave lower than the viola.  It is the bass member of the violin family of musical instruments, which also includes the violin, viola and the double bass.  The cello is used as a solo musical instrument, as well as in chamber music ensembles (e.g., string quartet), string orchestras, as a member of the string section of symphony orchestras, and some types of rock bands.  It is the second-largest and second lowest (in pitch) bowed string instrument in the modern symphony orchestra, the double bass being the largest and having the lowest (deepest) pitch. The Jap fiddle or Japanese fiddle was a one-stringed bowed instrument used by street performers, music hall performers, and vaudevillians around the start of the 20th century, particularly in the United Kingdom and United States.  The instrument was particularly associated with Cockney blackface performer G. H. Chirgwin.  A variant was later produced with a vibrating membrane and horn for amplification, as a one-stringed phonofiddle. The suroz is a bowed string instrument with a long neck, similar to a fiddle or sarangi and played vertically.  It is considered the national instrument of the Baloch people of Iran, Afghanistan, and Pakistan. Daya Shankar Kaul Nasim (Kashmiri: दया शंकर कौल नसीम , Urdu: دیا شنکر کول نسیم‎ ) was a Urdu poet of the 19th century who is best known for his epic "Gul Bakawali".  He was defended by Brij Narayan Chakbast when it was suggested that he was not the author of this book.  The poet lived from 1811–1845. Zia Mohiuddin Dagar (14 March 1929 – 28 September 1990), popularly known as Z. M. Dagar, was a North Indian (Hindustani) classical musician, one of the 19th generation of Dagar family dhrupad musicians.  He was largely responsible for the revival of the rudra vina as a solo concert instrument. The dhantara (or dhanotu) is a bowed string instrument found in Himachal Pradesh state of India.  The instrument is similar to the classical sarangi, but is more primitive, having only three melody strings and no "tarab" (sympathetic strings).  The instrument is popular among the Gaddi people of that state, and often decorated with flowers. Brij Narayan (Hindi: बृज नारायण ; IAST: Bṛj Nārāyaṇ ) (born 25 April 1952) is an Indian classical musician who plays the string instrument "sarod".  Narayan was born in the Indian state Rajasthan and began to study "sarod" from a young age under his father Ram Narayan and other teachers.  He won the All India Radio instrumentalist competition in 1967 and accompanied his father on a tour to Afghanistan in 1969.  Narayan graduated from the University of Mumbai in 1972 and has since worked on movies and toured Africa, Europe, and America.
