Document 2: Kay Musical Instrument Company: Kay Musical Instrument Company was a musical instrument manufacturer of the United States, in operation since the 1930s until the 1960s. It was established in 1931 at Chicago, Illinois by Henry Kay Kuhrmeyer, from the assets of the former Stromberg-Voisinet, which was founded as Groeschel Mandolin Company in 1890. Kay offered their first electric guitar in 1936—five years after the Rickenbacker "Frying pan", and the same year as the Gibson ES-150. Nonetheless, Kay is considered an "electric guitar pioneer" because Kuhrmeyer bought their past company, Stromberg-Voisinet, and produced the first commercial electric guitar, the "Stromberg Electro", in 1928.
Document 3: G&amp;L Musical Instruments: G&L is a guitar design and production company founded by Leo Fender, George Fullerton, and Dale Hyatt in the late 1970s. Fender sold his eponymous company Fender in 1965. He designed and produced instruments for Music Man in the 1970s through his company CLF Research. When relations with Music Man soured, G&L was created to continue operations outside of Music Man. The G&L name comes from the initials of George Fullerton and Leo Fender.
Document 4: Steel guitar: Steel guitar is a type of guitar or the method of playing the instrument. Developed in Hawaii in the late 19th and early 20th centuries, a steel guitar is usually positioned horizontally; strings are plucked with one hand, while the other hand changes the pitch of one or more strings with the use of a bar or slide called a steel (generally made of metal, but also of glass or other materials). The earliest use of an electrified steel guitar was first made in the early 1930s by Bob Dunn of Milton Brown and His Brownies, a western swing band from Fort Worth, Texas; the instrument was perfected in the mid to late 1930s by Fort Worth's Leon McAluff, who played for western swing band Bob Wills and His Texas Playboys. Nashville later picked up the use of the steel guitar in the early days of the late 1940s and early 1950s "Honky Tonk" country & western music with a number of fine steel guitarists backing names like :Hank Williams, Lefty Frizell and Webb Pierce. The term steel guitar is often mistakenly used to describe any metal body resophonic guitar.
Document 5: Classical guitar strings: 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.
Document 6: Acoustic bass guitar: The acoustic bass guitar (sometimes shortened to acoustic bass or initialized ABG) is a bass instrument with a hollow wooden body similar to, though usually larger than a steel-string acoustic guitar. Like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned E-A-D-G, an octave below the lowest four strings of the 6-string guitar, which is the same tuning pitch as an electric bass guitar.
Document 7: D'Angelico Guitars: D’Angelico Guitars is an American musical instrument manufacturer and guitar brand based in Manhattan, New York. The brand was initially founded by master-luthier John D'Angelico in 1932, in Manhattan's Little Italy. In 1999, Steve Pisani, John Ferolito Jr. and Brenden Cohen purchased the D’Angelico Guitars trademark. Cohen serves as the brand’s President and CEO. Original D’Angelico guitars are collector’s items and have been used by musicians including Pete Townshend, Eric Clapton, Bucky Pizarelli, Chet Atkins, and Chuck Wayne. Additionally, the D'Angelico Mel Bay New Yorker model was featured on the cover of the Mel Bay Publications' guitar method books for decades.

Document 10: Gibson ES-150: The Gibson Guitar Corporation's ES-150 guitar is generally recognized as the world's first commercially successful Spanish-style electric guitar. The ES stands for Electric Spanish, and it was designated "150" because it was priced (in an instrument/amplifier/cable bundle) at around $150. The particular sound of the instrument was formed by a combination of the specific bar-style pickup and its placement, and became famous due in large part to its endorsement by notable guitar players including Charlie Christian. After its introduction in 1936, it immediately became popular in jazz orchestras of the period. Unlike the usual acoustic guitars utilized in jazz, it was loud enough to take a more prominent position in ensembles. The guitar was produced with minor variations until 1940, when the ES-150 designation (the "V2") denoted a model with a different construction and a different pickup.
Document 11: Steel-string acoustic guitar: The steel-string acoustic guitar is a modern form of guitar that descends from the classical guitar, but is strung with steel strings for a brighter, louder sound. It is often referred to simply as an acoustic guitar, though the nylon-strung classical guitar is sometimes also called an acoustic guitar.
Document 12: Moon Guitars: Moon Guitars was established in 1979 by Jimmy Moon in a small workshop on the Island of Arran in Scotland. His reputation grew quickly and he was soon making (mostly electric guitars) and repairing instruments for many of Scotland’s finest musicians. A move to Glasgow was made in 1985 and for the following ten years, the company produced mostly custom electric instruments for many of Scotland’s well-known bands including Big Country, Texas, Simple Minds, Wet Wet Wet and Del Amitri. The next five years saw a change in the industry, and recognising this shift, Jimmy returned to his roots and began producing acoustic guitars and the entire mandolin family. Acoustic guitars range from Standard Series through to Master Grade instruments built with exotic timbers. The range also includes signature models for Bryan Adams and Scottish folk singer Dougie MacLean. Some current users of Moon acoustic instruments include: Adele, Ally McErlaine (Texas & Red Sky July), Bryan Adams, Dougie MacLean, Guy Berryman (Coldplay), Paolo Nutini, Trevor Rabin, Steve Earle, Peter Rowan, Roy Harper and the Scissor Sisters.
Document 13: Classical guitar: 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.
Document 14: Flat top guitar: A flat top guitar is a type of guitar body model which has a flat top (as opposed to archtop). The term "flat top" is usually used to refer to the most popular type of steel-string acoustic guitars; however, electric guitars such as the Fender Stratocaster, the Fender Telecaster and the Gibson Les Paul Junior and Special can be described as "flat top".
