Overdriven
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 be used with other instruments, such as electric bass, electric piano, synthesizer, 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. 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, grunge and heavy metal music, while the use of distorted bass has been essential in a genre of hip hop music and alternative hip hop know ...

Grunge
Grunge (sometimes referred to as the Seattle sound) is an alternative rock Music genre, genre and subculture that emerged during the in the U.S. state of Washington (state), Washington, particularly in Seattle and Music of Olympia, Washington, Olympia, and other nearby cities. Grunge fuses elements of punk rock and heavy metal music, heavy metal. The genre featured the Distortion (music), distorted electric guitar sound used in both genres, although some bands performed with more emphasis on one or the other. Like these genres, grunge typically uses electric guitar, bass guitar, drums, and vocals. Grunge also incorporates influences from indie rock bands such as Sonic Youth. Lyrics are typically angst-filled and introspective, often addressing themes such as social alienation, doubt, self-doubt, abuse, neglect, betrayal, social isolation, social and emotional isolation, emotional isolation, addiction, psychological trauma, and a desire for Liberty, freedom.

Heavy Metal Music
Heavy metal (or simply metal) is a Music genre, genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom and United States. With roots in blues rock, psychedelic rock and acid rock, heavy metal bands developed a thick, monumental sound characterized by distortion (music), distorted guitars, extended guitar solos, emphatic Beat (music), beats and loudness. In 1968, three of the genre's most famous pioneers – British bands Led Zeppelin, Black Sabbath and Deep Purple – were founded. Though they came to attract wide audiences, they were often derided by critics. Several American bands modified heavy metal into more accessible forms during the 1970s: the raw, sleazy sound and shock rock of Alice Cooper and Kiss (band), Kiss; the blues-rooted rock of Aerosmith; and the flashy guitar leads and party rock of Van Halen. During the mid-1970s, Judas Priest helped spur the genre's evolution by discarding much of its blues influence,Walser (1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effects Unit
An effects unit, effects processor, or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing. Common effects include distortion (music), distortion/overdrive, often used with electric guitar in electric blues and rock music; dynamics (music), dynamic effects such as volume pedals and Dynamic range compression, compressors, which affect loudness; linear filter, filters such as wah-wah pedals and graphic equalizers, which modify frequency ranges; modulation effects, such as Chorus (audio effect), chorus, flangers and phaser (effect), phasers; Pitch (music), pitch effects such as pitch shifter (audio processor), pitch shifters; and time effects, such as Reverb effect, reverb and Delay (audio effect), delay, which create echoing sounds and emulate the sound of different spaces. Most modern effects use solid-state electronics or digital signal processors. Some effects, particularly older ones such a ...

Hammond Organ
The Hammond organ is an electric organ invented by Laurens Hammond and John M. Hanert, first manufactured in 1935. Multiple models have been produced, most of which use sliding #Drawbars, drawbars to vary sounds. Until 1975, sound was created from rotating a metal tonewheel near an electromagnetic pickup, and Power amplifier, amplifying the electric signal into a speaker enclosure, speaker cabinet. The organ is commonly used with the Leslie speaker. Around two million Hammond organs have been manufactured. The organ was originally marketed by the Hammond Organ Company to Church (building), churches as a lower-cost alternative to the wind-driven pipe organ, or instead of a piano. It quickly became popular with professional jazz musicians in organ trios—small groups centered on the Hammond organ. Jazz club owners found that organ trios were cheaper than hiring a big band.

Vacuum Tube
A vacuum tube, electron tube, thermionic valve (British usage), or tube (North America) is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. It takes the form of an evacuated tubular envelope of glass or sometimes metal containing electrodes connected to external connection pins. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental Electronics, electronic functions such as signal amplifier, amplification and current Rectifier, rectification. Non-thermionic types such as vacuum phototubes achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light and measurement of its intensity. In both types the electrons are accelerated from the cathode to the anode by the electric field in the tube. The first, and simplest, vacuum tube, the diode or Flem ...

Distortion Effect
In signal processing, distortion is the alteration of the original shape (or other characteristic) of a signal. In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio signal representing sound or a video signal representing images, in an electronic device or communication channel. Distortion is usually unwanted, and so engineers strive to eliminate or minimize it. In some situations, however, distortion may be desirable. For example, in noise reduction systems like the Dolby system, an audio signal is deliberately distorted in ways that emphasize aspects of the signal that are subject to electrical noise, then it is symmetrically "undistorted" after passing through a noisy communication channel, reducing the noise in the received signal. Distortion is also used as a musical effect, particularly with electric guitars. The addition of noise or other outside signals ( hum, interference) is not considered dis ...

Guitar Amplifier
A guitar amplifier (or amp) is an electronic amplifier, electronic device or system that strengthens the electrical signal from a Pickup (music technology), pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden speaker enclosure, cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier (and preamplifier) circuits, requiring the use of a separate speaker cabinet–or it may be a ''combo'' amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight practice amplifiers with a single 6-inch speaker and a 10-watt amp to heavy combo amps with four 10-inch or four 12-inch speakers and a 100-watt amplifier, which are loud enough to use in a nightclub or bar performance. Guitar amplifiers can also modify ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clipping (audio)
Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. Driving an amplifier into clipping may cause it to output power in excess of its power rating. In the frequency domain, clipping produces strong harmonics in the high-frequency range (as the clipped waveform comes closer to a square wave). The extra high-frequency weighting of the signal could make tweeter damage more likely than if the signal was not clipped. In most cases, the distortion associated with clipping is unwanted, and is visible on an oscilloscope even if it is inaudible. However, clipping is often used in music for artistic effect, particularly guitar-dominant genres like blues, rock, and metal. Overview When an amplifier is pushed to create a signal with more power than its power supply can produce, it will amplify the signal only up to its maximum capacity, at which point the signal ...

Hip Hop Music
Hip-hop or hip hop (originally disco rap) is a popular music Music genre, genre that emerged in the early 1970s from the African Americans, African-American community of New York City. The style is characterized by its synthesis of a wide range of musical techniques. Hip-hop includes rapping often enough that the terms can be used synonymously. However, "hip-hop" more properly denotes an entire hip-hop culture, subculture. Other key markers of the genre are the disc jockey, turntablism, scratching, beatboxing, and hip hop production, instrumental tracks. Cultural interchange has always been central to the hip-hop genre. It simultaneously borrows from its social environment while commenting on it. The hip-hop genre and culture emerged from block parties in ethnic minority neighborhoods of New York City, particularly The Bronx, Bronx. DJs began expanding the instrumental Break (music), breaks of popular records when they noticed how excited it would make the crowds. The extend ...

Alternative Hip Hop
Alternative hip-hop (also known as alternative rap and experimental hip-hop) is a subgenre of hip-hop music that encompasses a wide range of styles that are not typically identified as mainstream. AllMusic defines it as comprising "hip-hop groups that refuse to conform to any of the traditional stereotypes of rap, such as gangsta, bass, hardcore, and party rap. Instead, they blur genres drawing equally from funk and pop/rock, as well as jazz, soul, reggae, and even folk." Alternative hip-hop developed in the late 1980s and experienced a degree of mainstream recognition during the early to mid-1990s. While some groups such as Arrested Development and the Fugees achieved commercial success, many alternative rap acts tend to be embraced by alternative rock listeners rather than hip-hop or pop audiences. The commercial and cultural momentum was impeded by the simultaneous emergence of significantly harder-edged West Coast gangsta rap. A resurgence came about in the late 1990s ...
