Document 6: 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.

As music critic Stuart Nicholson put it, "In terms of guitar prowess it was the equivalent of Roger Bannister breaking the four minute mile."
Document 9: 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.
