The guitar is a stringed musical instrument that is usually fretted and typically has six or twelve strings. It is usually held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A guitar pick may also be used to strike the strings. The sound of the guitar is projected either acoustically, by means of a resonant hollow chamber on the guitar, or amplified by an electronic pickup and an amplifier.

The ukulele, also called a uke, is a member of the lute family of instruments of Portuguese origin and popularized in Hawaii. It generally employs four nylon strings.

A power chord, also called a fifth chord, is a colloquial name for a chord on guitar, especially on electric guitar, that consists of the root note and the fifth, as well as possibly octaves of those notes. Power chords are commonly played with an amp with intentionally added distortion or overdrive effects. Power chords are a key element of many styles of rock, especially heavy metal and punk rock.

Zithers are a class of stringed instruments. Historically, it could be any instrument of the psaltery family. In modern terminology, it is more specifically an instrument consisting of many strings stretched across a thin, flat body, the topic of this article.

The vihuela is a 15th-century fretted plucked Spanish string instrument, shaped like a guitar but tuned like a lute. It was used in 15th- and 16th-century Spain as the equivalent of the lute in Italy and has a large resultant repertory. There were usually five or six doubled strings.

Music Man is an American guitar and bass guitar manufacturer. Originally formed in 1971 by Forrest White and Tom Walker, along with Leo Fender as a silent partner, the company started manufacturing electric and bass guitars under the Music Man name in 1974. In 1984 it was acquired by Ernie Ball, the subsidiary of which is branded as Ernie Ball Music Man.

Fingerstyle guitar is the technique of playing the guitar or bass guitar by plucking the strings directly with the fingertips, fingernails, or picks attached to fingers, as opposed to flatpicking. The term "fingerstyle" is something of a misnomer, since it is present in several different genres and styles of music—but mostly, because it involves a completely different technique, not just a "style" of playing, especially for the guitarist's picking/plucking hand. The term is often used synonymously with fingerpicking except in classical guitar circles, although fingerpicking can also refer to a specific tradition of folk, blues and country guitar playing in the US. The terms "fingerstyle" and "fingerpicking" are also applied to similar string instruments such as the banjo.

In music, a barre chord is a type of chord on a guitar or other stringed instrument played by using one finger to press down multiple strings across a single fret of the fingerboard.

In music, a guitar chord is a set of notes played on a guitar. A chord's notes are often played simultaneously, but they can be played sequentially in an arpeggio. The implementation of guitar chords depends on the guitar tuning. Most guitars used in popular music have six strings with the "standard" tuning of the Spanish classical guitar, namely E–A–D–G–B–E' ; in standard tuning, the intervals present among adjacent strings are perfect fourths except for the major third (G,B). Standard tuning requires four chord-shapes for the major triads.

Guitar tunings are the assignment of pitches to the open strings of guitars, including classical guitars, acoustic guitars, and electric guitars. Tunings are described by the particular pitches that are made by notes in Western music. By convention, the notes are ordered and arranged from the lowest-pitched string to the highest-pitched string, or the thickest string to thinnest, or the lowest frequency to the highest. This sometimes confuses beginner guitarists, since the highest-pitched string is referred to as the 1st string, and the lowest-pitched is the 6th string.

A resonator guitar or resophonic guitar is an acoustic guitar that produces sound by conducting string vibrations through the bridge to one or more spun metal cones (resonators), instead of to the guitar's sounding board (top). Resonator guitars were originally designed to be louder than regular acoustic guitars, which were overwhelmed by horns and percussion instruments in dance orchestras. They became prized for their distinctive tone, and found life with bluegrass music and the blues well after electric amplification solved the problem of inadequate volume.

John Richard Jorgenson is an American musician. Although best known for his guitar work with bands such as the Desert Rose Band and The Hellecasters, he is also proficient on the mandolin, mandocello, Dobro, pedal steel guitar, piano, upright bass, clarinet, bassoon, and saxophone. While a member of the Desert Rose Band, he won the Academy of Country Music's "Guitarist of the Year" award three consecutive years.

Among alternative tunings for guitar, a major-thirds tuning is a regular tuning in which each interval between successive open strings is a major third. Other names for major-thirds tuning include major-third tuning, M3 tuning, all-thirds tuning, and augmented tuning. By definition, a major-third interval separates two notes that differ by exactly four semitones.
