Question: Which man, Roupen Altiparmakian or George Duran, is a master of the violin and oud?
Context: George Duran (born George Kevork Guldalian on January 13, 1975) is a Venezuelan born American chef and entertainer who is currently a spokesman in commercials for Hunt's tomatoes.  He also became host of TLC's "Ultimate Cake Off" in its second season. Ultimate Cake Off is an American television series that currently airs on TLC.  The show is based on professional cake artists that go "head-to-head" in constructing cakes over five feet tall with the assistance of a team of chefs, designers etc. for a money prize.  Season one of the series, hosted by Michael Schulson, premiered on August 3, 2009.  Season two, hosted by George Duran, premiered on February 1, 2010.  Professional bakers Margaret Braun and Leigh Grode join the hosts as judges. The lavta is a plucked string instrument from Istanbul.  It has a small body made of many ribs using carvel bending technique, looking like a small (Turkish) oud, gut strings like an oud but only 7 strings in 4 courses and tunable: A dd gg c'c' (like the ud), or sometimes A dd aa d'd' (in intervals of 5ths like laouto as well as 4ths); also tuned to Turkish Bolahenk tuning C G D A which is G D A E concert pitch.  The adjustable frets are tied bits of gut on the fingerboard, at the microtonal intervals of the makam system, a significant difference from both fretless oud and 12-frets to the octave laouto, making its fretboard more related to instruments like tanbur.  The bridge usually has mustache-shaped ends.  The fingerboard is flush with the soundboard, which is often unvarnished, and has a carved and inlaid rosette.  Some lavta have a pegbox like the oud (angling down), others more like a guitar (or like a buzok or Greek laouto).  The tuning pegs are shaped like those of the violin, with 3 on the right side and 4 on the left side of the open tuning head. Jamil Bashir (Arabic: جميل بشير‎ ‎ ; b. Mosul, Iraq, 1920; d. London, September 24, 1977) was born to an ethnic Assyrian/Syriac Christian family and is the brother of Munir Bashir.  His father started to teach him the oud when he was around six years old, as his father was a singer, and an oud player.  The Iraqi Music Institute was opened in 1936, under administration of Hanna Petros (1896–1958), then in 1937 Sherif Muheddin Haydar and other professors joined the faculty of the Institute; Jamil Bashir was enrolled to learn Oud with Sherif Muheddin Haydar and Violin with Sando Albu.  He finished his oud study in 1943 and his violin study in 1946, and then worked at the Institute as an oud and violin teacher.  He also wrote a two-volume oud method.  Jamil Bashir was also a good singer, but he did not continue singing as he preferred the oud.  He died in London on 24 September 1977. Yorgo Bacanos (born in Silivri, Turkey in 1900, died in Istanbul in 1977; Γιώργος Μπατζανός in Greek) was a master oud player and improvisational composer of Ottoman classical music.  His father Haralambos was of Greek gypsy descent, and a legendary oud improviser, and several in his family were kemençe artists.  He was largely responsible for introducing the young Yorgo to music, presenting him with his first oud at the age of five.  Yorgo soon left school (the Saint Benoit High School) to concentrate on music full-time--he had made his first public appearance in the Eftalofos Club in Taksim at the age of twelve. Onnik Dinkjian (Armenian: Oննիկ Տինքճեան , born 1929) is a French born American-Armenian musician and singer.  He is father of Ara Dinkjian, and has appeared with his son as well as other Armenian musicians such as Roupen Altiparmakian playing oud.

George adds comedy to cooking as he explores each show's topic in the strangest possible ways.  For example, during the show on breakfast, George tested to see if an ostrich egg could be cooked sunny-side up.  He rarely is on a set, and he does most of the show on the streets of Norwalk, Connecticut, New York City, and Miami Beach, Florida, as well as in diners, restaurants and malls.
