Wah-wah (or wa-wa) is an imitative word (or onomatopoeia) for the sound of altering the resonance of musical notes to extend expressiveness, sounding much like a human voice saying the syllable wah. The wah-wah effect is a spectral glide, a "modification of the vowel quality of a tone". [1]
The word is derived from the sound of the effect itself; an imitative or onomatopoeia word. The effect's "wa-wa" sound was noted by jazz player Barney Bigard when he heard Tricky Sam Nanton use the effect on his trombone in the early 1920s. [2]
The wah-wah effect is believed to have originated in the 1920s, with brass instrument players finding they could produce an expressive crying tone by moving a mute, or plunger, in and out of the instrument's bell. [3] In 1921, trumpet player Johnny Dunn's use of this style inspired Tricky Sam Nanton to use the mute with the trombone. [2]
By the early 1960s, the sound of the acoustic technique had been emulated with electronic circuitry (Keen 1999;.Du Noyer 2003 , 375). For electric guitar the wah-wah pedal was invented.
The method of production varies from one type of instrument to another. On brass instruments, it is usually created by means of a mute, particularly with the harmon (also called a "wa-wa" mute) or plunger mute. Woodwind instruments may use "false fingerings" to produce the effect.
Any electrified instrument may use an auxiliary signal-processing device, or pedal. Often it is controlled by movement of the player's foot on a rocking pedal connected to a potentiometer. An alternative to players directly controlling the amount of effect is an 'auto-wah'. These devices, usually make harder hit notes more trembly with a more prominent wah wah effect. [4] Wah-wah effects are often used for soloing or for creating a "wacka-wacka" funk rhythm on guitar. [3] Although these electronic means are most often on electric guitar, they are also often used on electric piano. [5]
The wah-wah effect is produced by periodically bringing in and out of play treble frequencies while a note is sustained. Therefore, the effect is a type of spectral glide, a "modification of the vowel quality of a tone". [1]
The Electronic wah-wah effects are produced by controlling tone filters with a pedal. [6] An envelope follower circuit is used in the 'auto-wah'.( Hunter 2004 ) Subtractive synthesis can produce a similar effect.
Tricky Sam Nanton's wah-wah on trombone in Duke Ellington's Orchestra became well known as part of the so-called "jungle" effects of the band in the late 1920s. [2] This technique has been used in contemporary music. Karlheinz Stockhausen notates the use of the wah-wah mute in his Punkte (1952/1962) in terms of transitions between open to close using open and closed circles connected by a line. [7] Although the most common method of producing wah-wah on brass instruments is with a mute, some players have used electronic filtering, notably Miles Davis on trumpet. [5]
An effects unit or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing.
The term jazz guitar may refer to either a type of electric guitar or to the variety of guitar playing styles used in the various genres which are commonly termed "jazz". The jazz-type guitar was born as a result of using electric amplification to increase the volume of conventional acoustic guitars.
The trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group ranges from the piccolo trumpet with the highest register in the brass family, to the bass trumpet, which is pitched one octave below the standard B♭ or C Trumpet.
A mute is a device attached to a musical instrument which changes the instrument's tone quality (timbre) or lowers its volume. Mutes are commonly used on string and brass instruments, especially the trumpet and trombone, and are occasionally used on woodwinds. Their effect is mostly intended for artistic use, but they can also allow players to practice discreetly. Muting can also be done by hand, as in the case of palm muting a guitar or grasping a triangle to dampen its sound.
Joe "Tricky Sam" Nanton was an American trombonist with the Duke Ellington Orchestra.
A wah-wah pedal is a type of electric guitar effects pedal that alters the tone and frequencies of the guitar signal to create a distinctive sound, mimicking the human voice saying the onomatopoeic name "wah-wah". The pedal sweeps the peak response of a frequency filter up and down in frequency to create the sound, a spectral glide, also known as "the wah effect". The wah-wah effect originated in the 1920s, with trumpet or trombone players finding they could produce an expressive crying tone by moving a mute in and out of the instrument's bell. This was later simulated with electronic circuitry for the electric guitar when the wah-wah pedal was invented. It is controlled by movement of the player's foot on a rocking pedal connected to a potentiometer. Wah-wah effects are used when a guitarist is soloing, or creating a "wacka-wacka" funk-styled rhythm for rhythm guitar playing.
Lead guitar, also known as solo guitar, is a musical part for a guitar in which the guitarist plays melody lines, instrumental fill passages, guitar solos, and occasionally, some riffs within a song structure. The lead is the featured guitar, which usually plays single-note-based lines or double-stops. In rock, heavy metal, blues, jazz, punk, fusion, some pop, and other music styles, lead guitar lines are usually supported by a second guitarist who plays rhythm guitar, which consists of accompaniment chords and riffs.
A rhythm section is a group of musicians within a music ensemble or band that provides the underlying rhythm, harmony and pulse of the accompaniment, providing a rhythmic and harmonic reference and "beat" for the rest of the band. The rhythm section is often contrasted with the roles of other musicians in the band, such as the lead guitarist or lead vocals whose primary job is to carry the melody.
Keyboard expression is the ability of a keyboard musical instrument to change tone or other qualities of the sound in response to velocity, pressure or other variations in how the performer depresses the keys of the musical keyboard. Expression types include:
An expression pedal is an important control found on many musical instruments including organs, electronic keyboards and pedal steel guitar. The musician uses the pedal to control different aspects of the sound, commonly volume. Separate expression pedals can often be added to a guitar amplifier or effects unit and used to control many different aspects of the tone.
In music, a chorus effect occurs when individual sounds with approximately the same time, and very similar pitches, converge and are perceived as one. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device.
A spectral glide is a music-composition concept, consisting of a "modification of the vowel quality of a tone". Since the vowel quality of a tone is determined by the overtones, spectrum, or timbre of that tone, a spectral glide is a move from a spectrum characteristic of one vowel to a spectrum characteristic of another vowel. A spectral glide may be accomplished through a wah-wah, mute, or pedal, or through the modification of one's vocal tract while speaking, singing, or playing an instrument such as the didgeridoo. Lip-vibrated instruments with large mouthpieces such as tuba and trombone allow extensive modification of vowel quality, while woodwinds have a smaller range, with the exception of the flute in air-sound mode. Strings have the smallest range.
The following outline is provided as an overview of and topical guide to guitars:
The Dunlop Cry Baby is a popular wah-wah pedal, manufactured by Dunlop Manufacturing, Inc. The name Cry Baby was from the original pedal from which it was copied, the Thomas Organ/Vox Cry Baby wah-wah, first manufactured in 1966. Thomas Organ/Vox failed to register the name as a trademark, leaving it open for Dunlop. More recently, Dunlop manufactured the Vox pedals under licence, although this is no longer the case.
Distortion and overdrive are forms of audio signal processing used to alter the sound of amplified electric musical instruments, usually by increasing their gain, producing a "fuzzy", "growling", or "gritty" tone. Distortion is most commonly used with the electric guitar, but may also be used with other electric instruments such as electric bass, electric piano, and Hammond organ. Guitarists playing electric blues originally obtained an overdriven sound by turning up their vacuum tube-powered guitar amplifiers to high volumes, which caused the signal to distort. While overdriven tube amps are still used to obtain overdrive, especially in genres like blues and rockabilly, a number of other ways to produce distortion have been developed since the 1960s, such as distortion effect pedals. The growling tone of a distorted electric guitar is a key part of many genres, including blues and many rock music genres, notably hard rock, punk rock, hardcore punk, acid rock, and heavy metal music, while the use of distorted bass has been essential in a genre of hip hop music and alternative hip hop known as "SoundCloud rap".
Growling is a musical technique where the instrumentalist vocalizes into the instrument to alter quality of the sound. Growling is used primarily in rock and blues style playing, it is also frequently used in klezmer music; it is popular in the woodwind family of instruments, especially the saxophone, though it is also commonly used on brass instruments, as well. It is commonly used by mainstream artists such as Ben Webster, Illinois Jacquet and Earl Bostic. Outside of these styles and instruments, it is often considered a novelty effect.
Del Casher is an American guitarist and inventor. He invented Wah-wah pedal, the Ecco-Fonic, and the Fender Electronic Echo Chamber. He was the first to introduce the Roland Guitar Synthesizer for the Roland Corporation.
This is a list of jazz and popular music terms that are likely to be encountered in printed popular music songbooks, fake books and vocal scores, big band scores, jazz, and rock concert reviews, and album liner notes. This glossary includes terms for musical instruments, playing or singing techniques, amplifiers, effects units, sound reinforcement equipment, and recording gear and techniques which are widely used in jazz and popular music. Most of the terms are in English, but in some cases, terms from other languages are encountered.
Vintage musical equipment is older music gear, including instruments, amplifiers and speakers, sound recording equipment and effects pedals, sought after, maintained and used by record producers, audio engineers and musicians who are interested in historical music genres. While any piece of equipment of sufficient age can be considered vintage, in the 2010s the term is typically applied to instruments and gear from the 1970s and earlier. Guitars, amps, pedals, electric keyboards, sound recording equipment from the 1950s to 1970s are particularly sought. Musical equipment from the 1940s and prior eras is often expensive, and sought out mainly by museums or collectors.
The trombone is a musical instrument from the brass instrument family. Trombone's first premiere in jazz was with Dixieland Jazz as a supporting role within the Dixie Group. This role later grew into the spotlight as players such as J.J. Johnson and Jack Teagarden began to experiment more with the instrument, finding that it can fill in roles along with the saxophone and trumpet in Bebop Jazz. The trombone has since grown to be featured in standard big band group setups with 3 to 5 trombones depending on the arrangement. Even today the trombone is still growing in popularity with groups and in music with different techniques being attempted and brought up. A person who plays the trombone is called a trombone player or a trombonist.
