Guitar solo
A guitar solo is a melodic passage, instrumental section, or entire piece of music, pre-written 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.
Classical guitar
The classical guitar is an acoustical wooden guitar with six strings, usually nylon, as opposed to the metal strings used in metal stringed acoustic guitars used in other genres. Classical guitar is typically played by plucking individual strings with the fingernails or the fingertips. A classical guitar solo concert is typically called a recital; it may include a variety of works, e.g. works written originally for the lute or vihuela by composers such as John Dowland and Luis de Narváez, and also music written for the harpsichord by Domenico Scarlatti, for the baroque lute by Sylvius Leopold Weiss, for the baroque guitar by Robert de Visée or even Spanish-inspired music written for the piano by Isaac Albéniz and Enrique Granados. Johann Sebastian Bach is another composer who did not write for the guitar specifically, but whose music is often played on it as his baroque lute works have proved highly adaptable to the instrument.Of music written originally for guitar, the earliest influential composers stem from the classical period. They include Fernando Sor and Mauro Giuliani, it is noted that their music can be seen to be potentially influenced by Viennese classicism. In the 19th century guitar composers such as Johann Kaspar Mertz were influenced by music written for the piano. I Francisco Tárrega wrote more uniquely guitar music, incorporating stylized aspects of flamenco's Moorish influences into his romantic miniatures. This was part of late 19th century European trend towards musical nationalism. Albéniz and Granados contributed to this movement as they wrote within the same time period.
Some classical guitarists play concertos, which are solos written for performance with the accompaniment of an orchestra. Fewer classical guitar concertos have been written compared to concertos for multi-instrumental orchestras. Some potentially notable ones could include Joaquín Rodrigo's Concierto de Aranjuez and Fantasía para un gentilhombre. In the 2000s, it has been noted that classical guitar is appearing more in classical music, as contemporary composers are increasingly writing guitar concertos.
History
Composers of the Renaissance period who wrote for four course guitar include Alonso Mudarra, Miguel de Fuenllana, Adrian Le Roy and Guillaume de Morlaye. Composers of the baroque guitar include Gaspar Sanz, Robert de Visée and Francesco Corbetta. From approximately 1780 to 1850, the guitar had composers and performers including: Filippo Gragnani, Antoine de Lhoyer, Ferdinando Carulli, Francesco Molino, Fernando Sor, Mauro Giuliani, Niccolò Paganini, Dionisio Aguado, Luigi Legnani, Matteo Carcassi, Napoléon Coste and Johann Kaspar Mertz. Guitar soloist Andrés Segovia popularized the guitar with tours and early phonograph recordings in the 1920s. Modern classical guitar solo performers who are known for playing modern repertoire include Kazuhito Yamashita, Agustín Barrios, Paul Galbraith, and John Williams.Traditional and popular music
Blues, R&B and rock and roll
The term "guitar solo" often refers to electric guitar solos played in blues and in rock. The use of a guitar solo as an instrumental interlude was developed by blues musicians such as Lonnie Johnson, John Lee Hooker, Muddy Waters, and T-Bone Walker, and jazz like Charlie Christian. Ernest Tubb's 1940 honky tonk classic, "Walking the Floor over You" was the first "hit" recording to feature and highlight a solo by a standard electric guitar—though earlier hits featured electric lap steel guitars.Howlin' Wolf, Muddy Waters, Willie Dixon, and Jimmy Reed played in Chicago in a style characterized by the use of electric guitar, sometimes slide guitar, harmonica, and a rhythm section of bass and drums. In the late 1950s, a new blues style emerged on Chicago's West Side pioneered by Magic Sam, Buddy Guy and Otis Rush on Cobra Records. The 'West Side Sound' had strong rhythmic support from a rhythm guitar, bass guitar and drums and as perfected by Guy, Freddie King, Magic Slim and Luther Allison was dominated by amplified electric lead guitar. Other blues artists, such as John Lee Hooker had influences not directly related to the Chicago style. John Lee Hooker's blues is more "personal," based on Hooker's deep rough voice accompanied by a single electric guitar.
These and other blues guitarists as well as the fast-picking techniques derived from country and bluegrass inspired the appearance of many virtuoso blues rock fusion soloists, beginning in 1963 with Lonnie Mack's first major recordings. Jimi Hendrix was a psychedelic guitarist, and a pioneer in the use of distortion and audio feedback in his music. Through these artists and others, blues music influenced the development of rock music. Another important blues rock guitar soloist in the 1960s and 1970s was Eric Clapton. In the early 1970s, the Texas rock-blues style emerged, which used guitars in both solo and rhythm roles.
Rock
The earliest rock guitar solos, as exemplified by popular recordings of Duane Eddy and Link Wray in the late 1950s, were relatively simple instrumental melodies. In the early 1960s, instrumental surf music represented a step forward in the sonic complexity of rock guitar melodies. In 1963, the dramatic, technically advanced electric guitar solo rose to the fore with Lonnie Mack's hit records, "Memphis" and "Wham!", and soon, with the advent of blues rock and psychedelic rock in the mid-late 1960s, became a characteristic part of rock music. Later still, guitar solos became a defining feature of the rock genre of heavy metal, in which most songs feature a solo. Metal solos often showcase the virtuosity of the guitarists, especially in metal styles that use shred guitar techniques for rapid playing of scales and arpeggios. Since the 1960s, electric guitarists have often altered the timbre of their guitar adding electronic guitar effects such as reverb, distortion, delay, and chorus to make the sound fuller and add harmonic overtones. Other effects used in solos include the wah-wah pedal and the talk box.Rock bands often have two guitarists, designated "lead" and "rhythm", with the lead player performing the solos and instrumental melody lines while the rhythm player accompanies with chords or riffs. In some cases, two guitarists share the lead role. Most rock music is based around songs in traditional forms. The main formal features are verses, choruses, and bridges. The guitar solo is usually the most significant instrumental section of a mainstream rock song. In other rock-related genres, such as pop and dance music, the synthesizer usually plays this role.
In classic verse–chorus form, it often falls between the second chorus and third verse. Extended guitar solos are sometimes used as a song's outro, such as Christopher Cross' "Ride Like the Wind", Radiohead's "Paranoid Android", Lynyrd Skynyrd's "Free Bird", The Stooges' "I Wanna Be Your Dog", Pink Floyd's "Comfortably Numb", Guns N' Roses' "November Rain", Metallica's "Fade to Black", Led Zeppelin's "Black Dog", Journey's "Who's Crying Now", The Cult's "Love Removal Machine", The Beatles' "While My Guitar Gently Weeps",.38 Special's "Hold On Loosely", The Rolling Stones' "Sway", Pearl Jam's "Alive", Red Hot Chili Peppers' "Dani California", Cream's "White Room", AC/DC's "Let There Be Rock", Outlaws' "Green Grass and High Tides", The Alan Parsons Project's "Eye in the Sky" and Eagles' "Hotel California".
Solos can take place in the intro, such as "Voodoo Child " by Jimi Hendrix, "Since I've Been Loving You" by Led Zeppelin, "One" by Metallica, "Lazy" by Deep Purple, "I Want It All" by Queen, "Johnny B. Goode" by Chuck Berry, "Don't Take Me Alive" by Steely Dan, "Sails of Charon" by Scorpions and "Wish You Were Here" by Pink Floyd. In rarer cases, the guitar solo may come after the first chorus as opposed to the second, such as "Beast and the Harlot" by Avenged Sevenfold, "The Importance of Being Idle" by Oasis and "Black Summer" by Red Hot Chili Peppers.
The use of guitar solos in hard rock and heavy metal was notable during the 1980s, when rapid-fire "shredding" solos were common; a virtuoso lead guitarist of a band might be more well-known than the singer. During this time, players began to use advanced harmonics techniques more widely. Later, guitarists who had developed considerable technical facility began to release albums with instrumental-only guitar compositions. Guitar solos in popular music waned in fashion in the middle 1990s, coinciding with the rise in popularity of nu metal and grunge. Nu metal differed significantly from previous sub-genres of metal and abandoned guitar solos altogether, except for a few rare lead fills here and there, whilst grunge did not wholly abandon solos and included them from time to time. Guitar solos likewise became less prominent in many pop and popular rock music styles; either being trimmed down to a short four-bar transition or omitted entirely, in a vast departure from the heavy usage of solos in classic rock music from the 1960s, 1970s, 1980s, and early 1990s. Classic rock revival music heavily features soloing, along with classic rock bands that are still active as of 2018.
Occasionally, a song contains a two-part guitar solo with both rhythm and lead guitar taking solos, or dual solos with both lead and rhythm playing complementary solos—such as with Twisted Sister's "30", Iron Maiden's "Hallowed Be Thy Name", "The Trooper", Megadeth's "Holy Wars... The Punishment Due" or Deep Purple’s "Highway Star". Some rock bands use harmonized dual lead guitar solos as part of their signature sound, such as Wishbone Ash and Lovebites. This was first popularized by the Allman Brothers Band in their album At Fillmore East.
