Information:  - The violin family of musical instruments was developed in Italy in the 16th century. At the time the name of this family of instruments was violas da braccio which was used to distinguish them from the viol family (violas "da gamba"). The standard modern violin family consists of the violin, viola, cello, and double bass.  - Amati is the last name of a family of Italian violin makers , who lived at Cremona from about 1538 to 1740 . Their importance is considered equal to those of the Bergonzi , Guarneri and Stradivari families . Today , violins created by Nicolò Amati are evaluated at around $ 600,000 .  - A luthier is someone who builds or repairs string instruments generally consisting of a neck and a sound box. The word "luthier" comes from the French word "luth", which means lute. A luthier was originally a maker of lutes, but the term now includes makers of stringed instruments such as the violin or classical guitar. A luthier does not make harps or pianos, as these require different skills and construction methods because their strings are secured to a frame. The craft of making string instruments, or lutherie (sometimes spelled luthiery), is commonly divided into two main categories: makers of stringed instruments that are plucked or strummed, and those that are bowed. Since bowed instruments require a bow, the second category includes a subtype known as a bow maker or archetier. Luthiers may also teach string-instrument making, either through apprenticeship or formal classroom instruction.   - Yehudi Menuhin, Baron Menuhin, (22 April 191612 March 1999) was an American-born violinist and conductor, who spent most of his performing career in Britain. He is widely considered one of the greatest violinists of the 20th century.  - Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets.  - The Guarneri (often referred to in the Latinized form "Guarnerius") is the family name of a group of distinguished luthiers from Cremona in Italy in the 17th and 18th centuries, whose standing is considered comparable to those of the Amati and Stradivari families. Some of the world's most famous violinists, such as Niccolò Paganini, Jascha Heifetz, Yehudi Menuhin have preferred Guarneris to Stradivaris. The average Stradivari is stronger in the 200 Hz and 250 Hz bands and above 1.6 kHz. Del Gesùs are on average stronger from 315 Hz up to 1.25 kHz. These differences are perceived as a more brilliant sound and stronger fundamentals of the lowest notes of the Stradivari, versus a darker sound in the del Gesùs.  - Jascha Heifetz (10 December 1987) was a Lithuanian born violinist. Many consider him to be the greatest violinist of all time. Born in Wilno, Russian Empire (present-day Vilnius, Lithuania), he moved as a teenager to the United States, where his Carnegie Hall debut was rapturously received. He was a virtuoso since childhoodFritz Kreisler, another leading violinist of the twentieth century, said on hearing Heifetz's debut, "We might as well take our fiddles and break them across our knees."  - In music theory, a perfect fifth is the musical interval corresponding to a pair of pitches with a frequency ratio of 3:2, or very nearly so.  - Bluegrass music is a form of American roots music, and a related genre of country music. Influenced by the music of Appalachia, bluegrass has mixed roots in Irish, Scottish and English traditional music, and was also later influenced by the music of African-Americans through incorporation of jazz elements.  - The kit violin, dancing master's kit, or kit, is a stringed instrument. It is essentially a very small violin, designed to fit in a pocket  hence its other common name, the pochette (French for "small pocket"). It was used by dance masters in royal courts and other places of nobility, as well as by street musicians until around the 18th century. Occasionally, the rebec was used in the same way. Several are called for (as "violini piccoli alla francese" - small French violins) in Monteverdi's 1607 "Orfeo".  - Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms".  - Wood is a porous and fibrous structural tissue found in the stems and roots of trees, and other woody plants. It is an organic material, a natural composite of cellulose fibers which are strong in tension embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.  - Rock music is a genre of popular music that originated as "rock and roll" in the United States in the 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and the United States. It has its roots in 1940s' and 1950s' rock and roll, itself heavily influenced by blues, rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical sources.  - The violin is a wooden string instrument in the violin family. It is the smallest and highest-pitched instrument in the family in regular use. Smaller violin-type instruments are known, including the violino piccolo and the kit violin, but these are virtually unused in the 2010s. The violin typically has four strings tuned in perfect fifths, and is most commonly played by drawing a bow across its strings, though it can also be played by plucking the strings with the fingers (pizzicato). Violins are important instruments in a wide variety of musical genres. They are most prominent in the Western classical tradition and in many varieties of folk music. They are also frequently used in genres of folk including country music and bluegrass music and in jazz. Electric violins are used in some forms of rock music; further, the violin has come to be played in many non-Western music cultures, including Indian music and Iranian music. The violin is sometimes informally called a fiddle, particularly in Irish traditional music and bluegrass, but this nickname is also used regardless of the type of music played on it.  - Cremona is a city and "comune" in northern Italy, situated in Lombardy, on the left bank of the Po River in the middle of the "Pianura Padana" (Po valley). It is the capital of the province of Cremona and the seat of the local city and province governments. The city of Cremona is especially noted for its musical history and traditions, including some of the earliest and most renowned luthiers, such as Giuseppe Guarneri, Antonio Stradivari, and several members of the Amati family.  - Niccolò (or Nicolò) Paganini (27 October 178227 May 1840) was an Italian violinist, violist, guitarist, and composer. He was the most celebrated violin virtuoso of his time, and left his mark as one of the pillars of modern violin technique. His 24 Caprices for Solo Violin Op. 1 are among the best known of his compositions, and have served as an inspiration for many prominent composers.  - Country music is a genre of United States popular music that originated in the southern United States in the 1920s. It takes its roots from the southeastern genre of United States, such as folk music (especially Appalachian folk music), and blues music. Blues modes have been used extensively throughout its recorded history. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjos, electric and acoustic guitars, dobros and fiddles as well as harmonicas. According to Lindsey Starnes, the term "country music" gained popularity in the 1940s in preference to the earlier term "hillbilly music"; it came to encompass Western music, which evolved parallel to hillbilly music from similar roots, in the mid-20th century. The term "country music" is used today to describe many styles and subgenres. The origins of country music are the folk music of working-class Americans, who blended popular songs, Irish and Celtic fiddle tunes, traditional English ballads, and cowboy songs, and various musical traditions from European immigrant communities. In 2009 country music was the most listened to rush hour radio genre during the evening commute, and second most popular in the morning commute in the United States.  - String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner.   - Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music. "Traditional folk music" has been defined in several ways: as music transmitted orally, music with unknown composers, or music performed by custom over a long period of time. It has been contrasted with commercial and classical styles.  - Fiddle is another name for the bowed string musical instrument more often called a violin. It is also a colloquial term for the instrument used by players in all genres, including classical music. Fiddle playing, or fiddling, refers to various styles of music. Fiddle is also a common term among musicians who play folk music on the violin. The fiddle is part of many traditional (folk) styles of music which are aural traditions, taught 'by ear' rather than via written music. Fiddle is normally the term used for Irish Traditional Music.    What object entity has the relation of 'field of work' with the subject 'amati'?
