Flat-top or steel-string guitars are similar to the classical guitar, however, within the varied sizes of the steel-stringed guitar the body size is usually significantly larger than a classical guitar, and has a narrower, reinforced neck and stronger structural design. The robust X-bracing typical of the steel-string was developed in the 1840s by German-American luthiers, of whom Christian Friedrich "C. F." Martin is the best known. Originally used on gut-strung instruments, the strength of the system allowed the guitar to withstand the additional tension of steel strings when this fortunate combination arose in the early 20th century. The steel strings produce a brighter tone, and according to many players, a louder sound. The acoustic guitar is used in many kinds of music including folk, country, bluegrass, pop, jazz, and blues. Many variations are possible from the roughly classical-sized OO and Parlour to the large Dreadnought (the most commonly available type) and Jumbo. Ovation makes a modern variation, with a rounded back/side assembly molded from artificial materials.

Picks come in many shapes and sizes. Picks vary from the small jazz pick to the large bass pick. The thickness of the pick often determines its use. A thinner pick (between 0.2 and 0.5 mm) is usually used for strumming or rhythm playing, whereas thicker picks (between 0.7 and 1.5+ mm) are usually used for single-note lines or lead playing. The distinctive guitar sound of Billy Gibbons is attributed to using a quarter or peso as a pick. Similarly, Brian May is known to use a sixpence coin as a pick, while noted 1970s and early 1980s session musician David Persons is known for using old credit cards, cut to the correct size, as plectrums.
Although many people thought rock and roll would be a passing fad, by the 1960s it was clear this music was firmly rooted in American culture. Electric guitarists had become the superstars of rock. Live performances in large halls and open-air concerts increased the demand for greater volume and showmanship. Rock guitarists began to experiment, and new sounds and textures, like distortion and feedback, became part of the guitarist's language. Jimi Hendrix was rock's great master of manipulated sound.
We believe that music is a social activity so we present students with numerous opportunities to interact with each other. Each year we hold multiple recitals which offer a low-pressure opportunity to perform in front of an audience with other like-minded music students.  In addition to recitals, students frequently go out into the community to perform outreach concerts at local hospitals, schools, and nursing homes. Students also have the option to join group classes at our Santa Clara location. This offers students a chance to perform for each other more frequently, as well as join on our many performance ensembles. 
By now, you’ve already decided whether to stick with the Guitar or to drop it. If you’re one of the lucky few that stuck with it, in spite of having an extremely busy schedule with work and family obligations, congratulations. Contrary to popular belief, taking the time out for routine Guitar practice has tremendous benefits, even for the busiest of people.

Bolt-on necks, though they are historically associated with cheaper instruments, do offer greater flexibility in the guitar's set-up, and allow easier access for neck joint maintenance and repairs. Another type of neck, only available for solid body electric guitars, is the neck-through-body construction. These are designed so that everything from the machine heads down to the bridge are located on the same piece of wood. The sides (also known as wings) of the guitar are then glued to this central piece. Some luthiers prefer this method of construction as they claim it allows better sustain of each note. Some instruments may not have a neck joint at all, having the neck and sides built as one piece and the body built around it.
