Question: Beth Quist can play the national musical instrument of what country?

full_context: Document 1: Sitar: The sitar ( or ; Hindi: सितार Urdu: sitāra ) is a plucked stringed instrument used mainly in Hindustani music and Indian classical music. The instrument is believed to have been derived from the veena, an ancient Indian instrument, which was modified by a Mughal court musician to conform with the tastes of his Mughal patrons and named after a Persian instrument called the setar (meaning "three strings"). The sitar flourished in the 16th and 17th centuries and arrived at its present form in 18th-century India. It derives its distinctive timbre and resonance from sympathetic strings, bridge design, a long hollow neck and a gourd-shaped resonance chamber. In appearance, the sitar is similar to the tanpura, except that it has frets.
Document 2: Bethany Beardslee: Bethany Beardslee (born December 25, 1925) is an American soprano particularly noted for her collaborations with major 20th-century composers, such as Igor Stravinsky, Milton Babbitt, Pierre Boulez, George Perle, Sir Peter Maxwell Davies and her performances of great contemporary classical music by Arnold Schoenberg, Alban Berg, Anton Webern. Her legacy amongst midcentury composers was as a "composer's singer"—for her commitment to the highest art of new music. Milton Babbitt said of her "She manages to learn music no one else in the world can. She can work, work, work." In a 1961 interview for Newsweek, Beardslee flaunted her unflinching repertoire and disdain for commercialism: "I don't think in terms of the public... Music is for the musicians. If the public wants to come along and study it, fine. I don't go and try to tell a scientist his business because I don't know anything about it. Music is just the same way. Music is "not" entertainment."
Document 3: Aziz Herawi: Aziz Herawi (b. Herat, Afghanistan, c. 1952) is a noted musician from Afghanistan. He specializes in the dutar and rubab, both plucked string instruments. Afghan musician Aziz Herawi was seven years of age the first time he heard the strings of the dutar being plucked. He talked one of the family servants, who hid it in a blanket, into buying the instrument for him from a shepherd. The boy would wait until his father was asleep, then sneak into the woods surrounding their home. Alone, in the dark, he practiced, teaching himself to play the long-necked 12-stringed dutar.
Document 4: Monochord: A monochord, also known as sonometer (see below), is an ancient musical and scientific laboratory instrument, involving one (mono) string (chord). The term "monochord" is sometimes used as the class-name for any musical stringed instrument having only one string and a stick shaped body, also known as musical bows. According to the Hornbostel–Sachs system, string bows are bar zithers (311.1) while monochords are traditionally board zithers (314). The "harmonical canon", or monochord is, at its least, "merely a string having a board under it of exactly the same length, upon which may be delineated the points at which the string must be stopped to give certain notes," allowing comparison.
Document 5: Piano: The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700 (the exact year is uncertain), in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. The word "piano" is a shortened form of "pianoforte", the Italian term for the early 1700s versions of the instrument, which in turn derives from "gravicembalo col piano e forte" and "fortepiano". The Italian musical terms "piano" and "forte" indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the greater the velocity of a key press, the greater the force of the hammer hitting the strings, and the louder the sound of the note produced and the stronger the attack. The first fortepianos in the 1700s had a quieter sound and smaller dynamic range.
Document 6: Rubab (instrument): Rubab, robab or rabab (Pashto: رباب‎ , Urdu: رباب‎ , Azerbaijani: "Rübab" , Turkish: "Rübab" , Persian: رُباب‎ ‎ "rubāb", Tajik and Uzbek "рубоб") is a lute-like musical instrument originating from central Afghanistan. It derives its name from the Arab "rebab" which means "played with a bow" but in Central Asia the instrument is plucked and is distinctly different in construction. The "rubab" is mainly used by Pashtun, Tajik, Turkish, Kashmiri, Baluch, Azerbaijani, and Iranian Kurdish classical musicians. Rubab is one of the national musical instruments of Afghanistan and Pakistan.
Document 7: List of songs recorded by Björk: Icelandic singer and songwriter Björk has recorded more than one hundred songs for eight studio albums, two soundtrack albums, a compilation album, five remix albums and two collaboration albums. She is the sole writer and producer of most of the songs included in her albums. She also sometimes plays instruments during her recording sessions. Moreover, she has provided credited and uncredited contributions on songs recorded by other artists, including background vocals, songwriting, remixing and production.
Document 8: Beth Quist: Beth Quist, a multi-instrumentalist, vocalist, and composer, began playing piano at age 2. She has a 4-octave soprano voice, and plays piano, keyboards, santour (hammered dulcimer), dumbek, guitar, flute, and various other instruments.
Document 9: Tori Amos: Tori Amos (born Myra Ellen Amos, August 22, 1963 ) is an American singer-songwriter, pianist and composer. She is a classically trained musician with a mezzo-soprano vocal range.
Document 10: Steve Tibbetts: Tibbetts plays acoustic and electric guitar as well as exotic percussive instruments such as the kendang and kalimba. His musical compositions span several genres and styles including experimental, jazz, rock, ambient, and world music. He has self described his music as "post modern neo-primitivism". Often more than one genre or style is found in a single composition. A variety of techniques may be used with the guitar such as a string-bending technique sonically imitating a sarangi with a 12-string guitar while also alternating between ambient soundscape and Hendrix-like distorted and feedbacked leads with an electric guitar. He incorporates field-recordings such as the footsteps in the track "Running" from "Safe Journey", or the chanting of Nepalese villagers from the last tracks of "Big Map Idea". Tibbetts' recordings often include percussion by St Paul's Marc Anderson.
Document 11: Santoor: The santoor is a trapezoid-shaped hammered dulcimer or string musical instrument made of walnut, with seventy-two strings. It is the national musical instrument of Iran, and is also native to Jammu and Kashmir. It dates back to ancient times, and was called "Shatha Tantri Veena" in ancient Sanskrit texts. A primitive ancestor of this type of instrument was used in Mesopotamia (1600-911 BC) and Babylonia.
Document 12: Qanun (instrument): The kanun, ganoun or kanoon (Arabic: قانون‎ , "qānūn " ‎ ; Hebrew: קָנוֹן‎ , "qanon"; Persian: ‎ ‎ , "qānūn"; Turkish: "kanun" ; Armenian: քանոն , "k’anon " ; Azerbaijani: "qanun" ; Greek: κανονάκι , "kanonaki " ; Uyghur: قالون ‎, ULY: "qalon" ) is a string instrument played either solo, or more often as part of an ensemble, in much of the Middle East, Maghreb, West Africa, Central Asia, and southeastern regions of Europe. The name derives from the Arabic word "qanun", meaning "rule, law, norm, principle", which is borrowed from the ancient Greek word and musical instrument (rule), which in Latin was called canon (not to be confused with the European polyphonic musical style and composition technique known by the same name). Traditional and Classical musics executed on the qanun are based on Maqamat or Makamlar. As the historical relative of santur from the same geography, qanun is thought to trace its origins back to Assyria, where an ancestral homologue might have been used in Mesopotamian royal courts and religious ceremonies. The instrument today is a type of large zither with a thin trapezoidal soundboard that is famous for its unique melodramatic sound.
Document 13: Vichitra veena: The vichitra veena (Sanskrit: विचित्र वीणा is a plucked string instrument used in Hindustani music. It is similar to the Carnatic "gottuvadhyam" (chitra vina). It has no frets and is played with a slide.
Document 14: Croatian tamburica: Croatian tamburitza (tam•bu•rit•za) is a folk song played with a tambura (cousins with Russian balalaika and the Italian mandolin) and is accompanied with a dance. The origin is most commonly thought to be introduced from the Turks by way of Bosnia between the 14th and 16th century. Although, others believe that the tambura was introduced by the Persians. It was not until the 19th century that tamburitza gained popularity during several nationalist movements against the Austro-Hungarian Empire. Many societies such as Croatian, Slovak and Czech, used national folk songs and dance as an "expression of their national identity". During this time, the first Croatian tamburitza ensemble was created by Pajo Kolarić in 1847. Also, during early 20th century ethnomusicologist Professor Vinko Žganec, began to write down Croatian folk songs which in the past were not written, but passed down from generation to generation.
