Classical guitar in the context of "Guitar chord"

A twelve-string guitar (or 12-string guitar) is a steel-string guitar with 12 strings in six courses, which produces a thicker, more ringing tone than a standard six-string guitar. Typically, the strings of the lower four courses are tuned in octaves, with those of the upper two courses tuned in unison. The gap between the strings within each dual-string course is narrow, and the strings of each course are fretted and plucked as a single unit. The neck is wider, to accommodate the extra strings, and is similar to the width of a classical guitar neck. The sound, particularly on acoustic instruments, is fuller and more harmonically resonant than six-string instruments. The 12-string guitar can be played like a 6-string guitar as players still use the same notes, chords and guitar techniques like a standard 6-string guitar, but advanced techniques can be challenging as players need to play or pluck two strings simultaneously.

Structurally, 12-string guitars, especially those built before 1970, differ from six-string guitars in the following ways:

The evolution of classical guitars began with the influences of the gittern and vihuela in the 16th century and ended with the modern classical guitar in the mid-19th century.

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 (plucking individual notes with a single plectrum, commonly called a "pick"). 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.

Music arranged for fingerstyle playing can include chords, arpeggios (the notes of a chord played one after the other, as opposed to simultaneously) and other elements such as artificial harmonics, hammering on and pulling off notes with the fretting hand, using the body of the guitar percussively (by tapping rhythms on the body), and many other techniques. Often, the guitarist will play the melody notes, interspersed with the melody's accompanying chords and the deep bassline (or bass notes) simultaneously. Some fingerpicking guitarists also intersperse percussive tapping along with the melody, chords and bassline. Fingerstyle is a standard technique on the classical or nylon string guitar, but is considered more of a specialized technique on steel string guitars. Fingerpicking is less common on electric guitar. The timbre of fingerpicked notes is described as "result[ing] in a more piano-like attack," and less like pizzicato.

A guitar solo is a melodic passage, instrumental section, or entire piece of music, pre-written (or improvised) to be played on a classical, electric, or acoustic guitar. In 20th and 21st century traditional music and popular music such as blues, swing, jazz, jazz fusion, rock and heavy 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.

Guitar solos range from unaccompanied works for a single guitar to compositions with accompaniment from a few other instruments or a large ensemble. The accompaniment musicians for a guitar solo can range from a small ensemble such as a jazz quartet or a rock band, to a large ensemble such as an orchestra or big band. Unaccompanied acoustic guitar music is found in folk and classical music dating as far back as the instrument's first use in western music, the use of an acoustic guitar as a solo voice within an ensemble dates back at least to the Baroque concerto.

A guitarist (or a guitar player) is a person who plays the guitar. Guitarists may play a variety of guitar family instruments such as classical guitars, acoustic guitars, electric guitars, and bass guitars. Some guitarists accompany themselves on the guitar by singing or playing the harmonica, or both.

Son cubano (Spanish: [ˌsoŋ kuˈβano]) is a genre of music and dance that originated in the highlands of eastern Cuba during the late 19th century. It is a syncretic genre that blends elements of Spanish and African origin. Among its fundamental Hispanic components are the vocal style, lyrical metre and the primacy of the tres, derived from the Spanish guitar. On the other hand, its characteristic clave rhythm, call and response structure and percussion section (bongo, maracas, etc.) are all rooted in traditions of Bantu origin.

Around 1909 the son reached Havana, where the first recordings were made in 1917. This marked the start of its expansion throughout the island, becoming Cuba's most popular and influential genre. While early groups had between three and five members, during the 1920s the sexteto (sextet) became the genre's primary format. By the 1930s, many bands had incorporated a trumpet, becoming septetos, and in the 1940s a larger type of ensemble featuring congas and piano became the norm: the conjunto. The son became one of the main ingredients in the jam sessions known as descargas that flourished during the 1950s.
