Bass guitar
The bass guitar (), also known as the electric bass guitar, electric bass, or simply the bass, is the lowest-pitched member of the guitar family. It is similar in appearance and construction to an electric but with a longer neck and scale length. The electric bass guitar most commonly has four strings, though five- and six-stringed models are also built. Since the mid-1950s, the bass guitar has replaced the double bass in popular music due to its lighter weight, smaller size, most models' inclusion of frets for easier intonation, and electromagnetic pickups for amplification. Another reason the bass guitar replaced the double bass is because the double bass is "acoustically imperfect" like the viola. For a double bass to be acoustically perfect, its body size would have to be twice as that of a cello rendering it unplayable, so the double bass is made smaller to make it playable. The electric bass with its pickups an amplifier addresses the compromises of a double bass by allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fender Jazz Bass
The Fender Jazz Bass (often shortened to "J-Bass") is the second model of Bass guitar, electric bass guitar created by Leo Fender. It is distinct from the Fender Precision Bass, Precision Bass in that its tone is brighter and richer in the midrange and treble with less emphasis on the Harmonic series (music), fundamental frequency. The body shape is also different from the Precision Bass, in that the Precision Bass has a symmetrical lower bout on the body, designed after the Telecaster and Stratocaster lines of guitars, while the Jazz Bass has an offset lower bout, mimicking the design aesthetic of the Fender Jaguar, Jaguar and Fender Jazzmaster, Jazzmaster guitars. History First introduced in 1960 as the Deluxe Model, it borrowed design elements from the Fender Jazzmaster, Jazzmaster guitar. It was renamed the Jazz Bass as Fender felt that its redesigned neck—narrower and more rounded than that of the Precision Bass—would appeal more to jazz musicians. The Jazz Bass has tw ...

Intonation (music)
In music, intonation is the pitch accuracy of a musician or musical instrument. Intonation may be flat, sharp, or both, successively or simultaneously. In vocal music, intonation also signifies the singing of an opening phrase. Interval, melody, and harmony The lower or upper pitch of an interval may be sharp or flat, or both pitches of an interval. If the lower pitch is sharp or the upper pitch is flat, the interval may be said to be flat given that as a whole it is too narrow; while if the lower pitch is flat or the upper pitch is sharp, the interval may be said to be sharp given that as a whole it is too wide. Intervals are conventionally measured from the bottom, as such in an interval that is too wide the upper pitch is thus sharp. Intonation exists within the context of musical temperament, of which there are several types. However, the interval itself may be in tune, in relation to itself (i.e. both notes of the interval are in tune in relation to each other), but ...

Vibrating
Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum and alternating current. Oscillations can be used in physics to approximate complex interactions, such as those between atoms. Oscillations occur not only in mechanical systems but also in dynamic systems in virtually every area of science: for example the beating of the human heart (for circulation), business cycles in economics, predator–prey population cycles in ecology, geothermal geysers in geology, vibration of strings in guitar and other string instruments, periodic firing of nerve cells in the brain, and the periodic swelling of Cepheid variable stars in astronomy. The term ''vibration'' is precisely used to describe a mechanical oscillation. Oscillation, especially rapid oscillation, may be an undesirable phenomenon in process ...

Fretless Bass
A fretless bass is an electric bass guitar whose neck lacks frets and thus is smooth like traditional string instruments, and like the neck of an acoustic double bass. While the fretless bass is played in all styles of music, it is most common in pop, rock, and jazz. It first saw widespread use during the 1970s, although some players used them before then. The Fender Precision Bass was introduced in 1951, with frets to help performers find the proper note (''i.e.'' to provide ''precision''). This concept of the fretted bass guitar has since become the standard, as other companies followed with similar electric fretted basses, like the Höfner 500/1 of Beatle Paul McCartney, which resembled a viol but with frets. The first fretless electric bass guitars appeared around 1961, from modifications made by players. Historically the most significant, while not likely the first, example of this is the Rolling Stones bassist Bill Wyman, who wanted to change the frets of his bass guit ...

DI Unit
A DI unit (direct input or direct inject) is an electronic device typically used in recording studios and in sound reinforcement systems to connect a high output impedance unbalanced output signal to a low-impedance, microphone level, balanced input, usually via an XLR connector and XLR cable. DIs are frequently used to connect an electric guitar or electric bass to a mixing console's microphone input jack. Its signal comes "direct" from the source instrument without passing through the air as sound waves, and thus is isolated from other sounds and avoids effects of microphone or room acoustics. The DI performs level matching, balancing, and either active buffering or passive impedance matching or impedance bridging. DI units are typically metal boxes with input and output jacks and, for more expensive units, “ground lift” and attenuator switches. DI boxes are extensively used with professional and semi-professional PA systems, professional sound reinforcement systems a ...

Piezo-electric
Piezoelectricity (, ) is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. The piezoelectric effect is a reversible process: materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electric field. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied. The inverse piezoelectric effect is used in the pro ...

Electromagnetic
In physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely intertwined phenomena. Electromagnetic forces occur between any two charged particles. Electric forces cause an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs between charged particles in relative motion. These two forces are described in terms of electromagnetic fields. Macroscopic charged objects are described in terms of Coulomb's law for electricity and Ampère's force law for magnetism; the Lorentz force describes microscopic charged particles. The electromagnetic force is responsible for ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bass Amplifier
A bass amplifier (also abbreviated to bass amp) is a musical instrument electronic device that uses electrical power to make lower-pitched instruments such as the bass guitar or double bass loud enough to be heard by the performers and audience. Bass amps typically consist of a preamplifier, tone controls, a power amplifier and one or more loudspeakers ("drivers") in a cabinet. While bass amps share many features with the guitar amplifiers used for electric guitar, they are distinct from other types of amplification systems, due to the particular challenges associated with low-frequency sound reproduction. This distinction affects the design of the loudspeakers, the size and design of the speaker cabinet and the design of the preamplifier and amplifier. Speaker cabinets for bass amps usually incorporate larger loudspeakers (e.g., speakers are more common for bass than for electric guitar amps) or more speakers and larger cabinet sizes than those used for the amplificat ...

Plectrum
A plectrum is a small flat tool used for plucking or strumming of a stringed instrument. For hand-held instruments such as guitars and mandolins, the plectrum is often called a pick and is held as a separate tool in the player's hand. In harpsichords, the plectra are attached to the jack mechanism. Plectra wielded by hand Guitars and similar instruments A plectrum for electric guitars, acoustic guitars, bass guitars and mandolins is typically a thin piece of plastic or other material most commonly shaped like a pointed teardrop or triangle, though the size, gauge, shape and width may vary considerably. Banjo and guitar players may wear a metal or plastic thumb pick mounted on a ring, and bluegrass banjo players often wear metal or plastic fingerpicks on their fingertips. Many guitarists use fingerpicks as well. Guitar picks are made of a variety of materials, including celluloid, metal, and rarely other exotic materials such as turtle shell, but today delrin (a synthetic ...

G (musical Note)
G, also called Sol or So, is the fifth note of the fixed-do solfège starting on C. It is the fifth note and the eighth semitone of the solfège. As such it is the dominant, a perfect fifth above C or perfect fourth below C. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of middle G (G4) note is approximately 391.995 Hz. See pitch for a discussion of historical variations in frequency. It has enharmonic equivalents of F (F-double sharp) and A (A-double flat). In the medieval period the musical note G was known as gesolreut within the Guidonian hand hexachord system.

D (musical Note)
D is a musical note a whole tone above C, and is known as Re within the fixed-Do solfege system. Its enharmonic equivalents are C (C-double sharp) and E (E-double flat). It is the third semitone of the solfège. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of middle D (D4) is approximately 293.665Hz.

A (musical Note)
A is a musical note equivalent to 440 Hz in typical A440 tuning. It is the sixth note of La and the tenth semitone of the fixed-do solfège. Its enharmonic equivalents are B (B double-flat) and G (G double-sharp). "A" is generally used as a standard for tuning. When the orchestra tunes, the oboe plays an "A" and the rest of the instruments tune to match that pitch. Every string instrument in the orchestra has an A string, from which each player can tune the rest of their instrument. "A" is also used in combination with a number (e.g. A-440) to label the pitch standard. The number designates the frequency in hertz. A lower number indicates a lower pitch. The International Standards Organization (ISO) has standardized the pitch at A-440. However, tuning has varied over time, geographical region, or instrument maker. In 17th-century Europe, tunings ranged from about A-374 to A-403, approximately two to three semitones below A-440. Historical examples exist of instrumen ...
