Context_1 : Dominic Frasca (born April 5, 1967) is a guitarist, originally from Akron, Ohio, but living in New York City since the early 1990s. He began playing hard rock guitar at age 13, but gravitated into classical after finding an ad for classical guitar lessons in a school trash can. Frasca originally entered the University of Arizona with the intent of studying classical guitar, but realized after a year that it wasn't his style. Leaving the University of Arizona after his scholarship for classical guitar was canceled, he enrolled in colleges in Ohio, also trying Yale University, where he first met composer Marc Mellits. The friendship and collaboration did not begin until Mellits and Frasca met once more, through a mutual friend at Cornell University. Context_2 : The classical guitar (also known as concert guitar, classical acoustic, nylon-string guitar, or Spanish guitar) is the member of the guitar family used in classical music. It is an acoustical wooden guitar with strings made of nylon, rather than the metal strings used in acoustic and electric guitars. The traditional classical guitar has twelve frets clear of the body and is held on the left leg, so that the hand that plucks or strums the strings does so near the back of the soundhole (this is called the classical position). The modern steel string guitar, on the other hand, usually has fourteen frets clear of the body (see Dreadnought) and is commonly played off the hip. Context_3 : A guitar solo is a melodic passage, instrumental section, or entire piece of music written for a classical guitar, electric guitar or an acoustic guitar. In 20th and 21st century traditional music and popular music such as blues, swing, jazz, jazz fusion, rock and metal guitar solos often contain virtuoso techniques and varying degrees of improvisation. Guitar solos on classical guitar, which are typically written in musical notation, are also used in classical music forms such as chamber music and concertos. Context_4 : A guitalele (sometimes spelled guitarlele or guilele), also called a kiku, is a guitar-ukulele hybrid, that is, "a 1/4 size" guitar, a cross between a classical guitar and a tenor or baritone ukulele. The guitalele combines the portability of a ukulele, due to its small size, with the six single strings and resultant chord possibilities of a classical guitar. It may include a built-in microphone that permits playing the guitalele either as an acoustic guitar or connected to an amplifier. The guitalele is variously marketed (and used) as a travel guitar or children's guitar. Context_5 : Classical guitar strings are strings manufactured for use on classical guitars. While steel-string acoustic guitar strings and electric guitar strings are made of metal, modern classical guitar strings are made of nylon and nylon wound with wire, which produces a different sound to the metal strings. Classical guitar strings were originally made with animal intestine and silk wound with animal intestine up until World War II, when war restrictions led Albert Augustine Ltd. to develop nylon strings. Nylon guitar strings were put into production in 1948. Strings made from fluorocarbon polymers have since been developed and are the main alternative to nylon strings. Context_6 : This article lists the classical guitar music in the classical guitar repertoire. It includes baroque guitar and vihuela music, but not lute music. This music is most commonly performed by classical guitarists and requires the use of a variety of classical guitar techniques to play. Context_7 : Padet Netpakdee (born 1987) is a Thai classical guitarist. He was born in Chiang Mai, a province in the northern part of Thailand that is rich in arts and cultures. His music journey started when he started to learn traditional and regional musical instruments at very young age. After his mother introduced him to a guitar, he started taking formal classical guitar lessons when he was ten years old with local classical guitar instructors (Pracha Jaitae, Manoon Ploypradab). Context_8 : The Seasons, Op. 37a (also seen as Op. 37b; Russian: ; published with the French title Les Saisons), is a set of twelve short character pieces for solo piano by the Russian composer Pyotr Ilyich Tchaikovsky. Each piece is the characteristic of a different month of the year in the northern hemisphere. The work is also sometimes heard in orchestral and other arrangements by other hands. Individual excerpts have always been popular "Troika" (November) was a favourite encore of Sergei Rachmaninoff, and "Barcarolle" (June) was enormously popular and appeared in numerous arrangements (for orchestra, violin, cello, clarinet, harmonium, guitar and even mandolin). Context_9 : Vladislav Bulakhov (Russian: ) is a Russian conductor, violinist, and Honoured Artist of Russia. He graduated from the Gnessin State Musical College in 1984 and prior to it have served under guidance from Igor Zhukov at the Moscow Chamber Orchestra. His conducting career began when he introduced "The Seasons" at the First International Festival of Classical Guitar in November 1994. After that he performed it in Moscow and Germany in both of which it boasted him a success. Context_10 : Tigran Maytesian (Russian: ; born November 10, 1970) is an Armenian-born Russian-Belgian classical violinist, Doctor of Arts. He is a soloist and chamber musician, a professor, past artistic director of the International Festival des Minimes in Brussels, the International Festival Sint Carolus Borromeuskerk in Antwerp and the International Festival at the Cathedrale Notre-Dame-de-la-Treille de Lille, France, and currently artistic director of the Festival St Andrieskerk in Antwerp, Festival Catharina and Festival Chapel for Europe in Brussels, a scientific researcher and consultant who resides and works in Belgium. fact_1 : His conducting career began when he introduced "The Seasons" at the First International Festival of Classical Guitar in November 1994. fact_2 : The Seasons, Op. 37a (also seen as Op. 37b; Russian: ; published with the French title Les Saisons), is a set of twelve short character pieces for solo piano by the Russian composer Pyotr Ilyich Tchaikovsky.
