Sound Box
A sound box or sounding box (sometimes written soundbox) is an open chamber in the body of a musical instrument which modifies the sound of the instrument, and helps transfer that sound to the surrounding air. Objects respond more strongly to vibrations at certain frequencies, known as resonances. The frequency and strength of the resonances of the body of a musical instrument have a significant impact on the tone quality it produces. The air inside the chamber has its own resonances, and these interact with the resonances of the body, altering the resonances of the instrument as a whole. The sound box typically adds resonances at lower frequencies, enhancing the lower-frequency response of the instrument. The distinctive sound of an instrument with a sound box owes a lot to the alteration made to the tone. A sound box is found in most string instruments. The most notable exceptions are some electrically amplified instruments like the solid body electric guitar or the electric vio ...

Guitarist Girl
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. Techniques The guitarist may employ any of several methods for sounding the guitar, including finger-picking, depending on the type of strings used (either nylon or steel), and including strumming with the fingers, or a guitar pick made of bone, horn, plastic, metal, felt, leather, or paper, and melodic flatpicking and finger-picking. The guitarist may also employ various methods for selecting notes and chords, including fingering, thumbing, the barre (a finger lying across many or all strings at a particular fret), and guitar slides, usually made of glass or metal. These left- and right-hand techniques may be intermixed in performance. Notable guitarists Rock, metal, jazz, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banjo
The banjo is a stringed instrument with a thin membrane stretched over a frame or cavity to form a resonator. The membrane is typically circular, and in modern forms is usually made of plastic, where early membranes were made of animal skin. Early forms of the instrument were fashioned by African Americans and had African antecedents. In the 19th century, interest in the instrument was spread across the United States and United Kingdom by traveling shows of the 19th-century minstrel show fad, followed by mass production and mail-order sales, including instructional books. The inexpensive or home-made banjo remained part of rural folk culture, but five-string and four-string banjos also became popular for home parlor music entertainment, college music clubs, and early 20th century jazz bands. By the early 20th century, the banjo was most frequently associated with folk, cowboy music, and country music. By mid-century it had come to be strongly associated with bluegrass. Eventu ...

Frequency Response
In signal processing and electronics, the frequency response of a system is the quantitative measure of the magnitude and Phase (waves), phase of the output as a function of input frequency. The frequency response is widely used in the design and analysis of systems, such as audio system, audio and control systems, where they simplify mathematical analysis by converting governing differential equations into algebraic equations. In an audio system, it may be used to minimize audible distortion by designing components (such as microphones, Audio power amplifier, amplifiers and loudspeakers) so that the overall response is as flat (uniform) as possible across the system's Bandwidth (signal processing), bandwidth. In control systems, such as a vehicle's cruise control, it may be used to assess system Stability theory, stability, often through the use of Bode plots. Systems with a specific frequency response can be designed using analog filter, analog and digital filters. The frequency ...

Filter (signal Processing)
In signal processing, a filter is a device or process that removes some unwanted components or features from a Signal (electronics), signal. Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal. Most often, this means removing some frequency, frequencies or frequency bands. However, filters do not exclusively act in the frequency domain; especially in the field of image processing many other targets for filtering exist. Correlations can be removed for certain frequency components and not for others without having to act in the frequency domain. Filters are widely used in electronics and telecommunication, in radio, television, audio recording, radar, control systems, music synthesis, image processing, computer graphics, and structural dynamics. There are many different bases of classifying filters and these overlap in many different ways; there is no simple hierarchical classification. Fil ...

Basic Physics Of The Violin
Violin acoustics is an area of study within musical acoustics concerned with how the sound of a violin is created as the result of interactions between its many parts. These acoustic qualities are similar to those of other members of the violin family, such as the viola. The energy of a vibrating string is transmitted through the bridge to the body of the violin, which allows the sound to radiate into the surrounding air. Both ends of a violin string are effectively stationary, allowing for the creation of standing waves. A range of simultaneously produced harmonics each affect the timbre, but only the fundamental frequency is heard. The frequency of a note can be raised by the increasing the string's tension, or decreasing its length or mass. The number of harmonics present in the tone can be reduced, for instance by the using the left hand to shorten the string length. The loudness and timbre of each of the strings is not the same, and the material used affects sound qualit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acoustic Guitar
An acoustic guitar is a musical instrument in the string family. When a string is plucked, its vibration is transmitted from the bridge, resonating throughout the top of the guitar. It is also transmitted to the side and back of the instrument, resonating through the air in the body, and producing sound from the sound hole. While the original, general term for this stringed instrument is ''guitar'', the retronym 'acoustic guitar' – often used to indicate the Steel-string acoustic guitar, steel stringed model – distinguishes it from an electric guitar, which relies on electronic amplification. Typically, a guitar's body is a sound box, of which the top side serves as a Sound board (music), sound board that enhances the vibration sounds of the strings. In Guitar tunings, standard tuning the guitar's six strings are tuned (low to high) E2 A2 D3 G3 B3 E4. Guitar strings may be plucked individually with a Guitar pick, pick (plectrum) or fingertip, or Strumming, strummed to play Ch ...

Bass Reflex
A bass reflex system (also known as a ported, vented box or reflex port) is a type of loudspeaker enclosure that uses a port (hole) or vent cut into the cabinet and a section of tubing or pipe affixed to the port. This port enables the sound from the rear side of the diaphragm to increase the efficiency of the system at low frequencies as compared to a typical sealed- or closed-box loudspeaker or an infinite baffle mounting. A ''reflex port'' is the distinctive feature of this popular Loudspeaker enclosure, enclosure type. The design approach enhances the reproduction of the lowest frequency, frequencies generated by the woofer or subwoofer. The port generally consists of one or more tubes or pipes mounted in the front (Loudspeaker enclosure, baffle) or rear face of the enclosure. Depending on the exact relationship between driver Thiele/Small, parameters, the enclosure volume (and filling if any), and the tube cross-section and length, the efficiency can be substantially improve ...

Loudspeaker
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. The driver is a linear motor connected to a diaphragm, which transmits the motor's movement to produce sound by moving air. An audio signal, typically originating from a microphone, recording, or radio broadcast, is electronically amplified to a power level sufficient to drive the motor, reproducing the sound corresponding to the original unamplified signal. This process functions as the inverse of a microphone. In fact, the ''dynamic speaker'' driver—the most common type—shares the same basic configuration as a dynamic microphone, which operates in reverse as a generator. The dynamic speaker was invented in 1925 by Edward W. Kellogg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluegrass Music
Bluegrass music is a genre of American roots music that developed in the 1940s in the Appalachian region of the United States. The genre derives its name from the band Bill Monroe and the Blue Grass Boys. Bluegrass has roots in African American genres like blues and jazz and North European genres, such as Irish ballads and dance tunes. Unlike country, it is traditionally played exclusively on acoustic instruments such as the fiddle, mandolin, banjo, guitar and upright bass. It was further developed by musicians who played with Monroe, including 5-string banjo player Earl Scruggs and guitarist Lester Flatt. Bill Monroe once described bluegrass music as, "It's a part of Methodist, Holiness and Baptist traditions. It's blues and jazz, and it has a high lonesome sound." Bluegrass features acoustic stringed instruments and emphasizes the off-beat. The off-beat can be "driven" (played close to the previous bass note) or "swung" (played farther from the previous bass note). N ...

Clawhammer
Clawhammer, sometimes called down-picking, overhand, or most commonly known as frailing, is a distinctive banjo playing style and a common component of American old-time music. The style likely descends from that of West African lutes, such as the akonting which are also the direct ancestors of the banjo. The principal difference between clawhammer style and other styles is the picking direction. Traditional picking styles ( classic banjo), including those for folk, bluegrass, and classical guitar, consist of an up-picking motion by the fingers and a down-picking motion by the thumb; this is also the technique used in the Scruggs style for the banjo. Clawhammer picking, by contrast, is primarily a down-picking style. The hand assumes a claw-like shape and the strumming finger is kept fairly stiff, striking the strings by the motion of the hand at the wrist or elbow, rather than a flicking motion by the finger. In its most common form on the banjo, only the thumb and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erhu
The (; ) is a Chinese two-stringed bowed musical instrument, more specifically a spike fiddle, that is sometimes known in the Western world as the ''Chinese violin'' or a ''Chinese two-stringed fiddle''. It is used as a solo instrument as well as in small ensembles and large orchestras. It is the most popular of the family of traditional bowed string instruments used by various ethnic groups of China. As a very versatile instrument, the is used in both traditional and contemporary music arrangements, such as pop, rock and jazz. History The can be traced back to proto-Mongolic instruments which first appeared in China during the Tang dynasty. It is believed to have evolved from the (). The is believed to have originated from the Xi people located in current northeast China. The first Chinese character of the name of the instrument (, , 'two') is believed to come from the fact that it has two strings. An alternate explanation states that it comes from the fact that i ...

Sound Board (music)
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges, allowing some to even hear ultrasounds. Definition Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation.
