The bazantar is a custom made string instrument invented by musician Mark Deutsch, [1] who worked on the design between 1993 and 1997.
The Bazantar is a six-string acoustic bass, fitted with an additional twenty-nine sympathetic strings and four drone strings. The instrument possesses a melodic range of over five octaves, and its sympathetic range spans four octaves. The inventor intends this to create an interplay between melodic, sympathetic, and drone strings to produce a more resonant sound than a conventional upright bass.
In the late 1980s, Mark Deutsch began exploring North Indian classical music. The subtlety of this style, combined with his pursuits on the sitar, inspired him to delve deeper into the study of music. He started exploring the mathematics of sound, particularly music's underlying frequency structure. This search revealed nonlinear mathematical patterns that exist in sound and are found universally in the natural world, including the overtone series, fractals, the golden mean, seashells, and the Fibonacci series.
In 1993, Mark began work on the first prototype of the Bazantar, an acoustic bass with additional sympathetic and drone strings. His intent was to create an instrument that would take advantage of these nonlinear mathematical patterns and make them more consciously audible. The difficulty lay in engineering a design that would be able to withstand the tension of the additional strings. He devised the unique solution of constructing a separate housing that would contain both the sympathetic strings and their resultant tension, which would then be mounted onto the instrument. After much experimentation, a finalized version was completed in October 1997.
In the finalized version, the drone strings are positioned outside the Bazantar's lowest melody string on a bass bridge, which has been modified to support this configuration. The sympathetic strings are held in a modular graphite housing that is positioned between the feet of the main bridge and mounted at the bottom of the tailpiece and at the base of the neck, underneath the fingerboard. The torque these strings create is contained within this housing. Because none of this torque is transferred to the instrument's body, the stress to its structure is greatly decreased, allowing for increased flexibility throughout the entire design. The Bazantar's engineering strategy enables it to maintain more strings at higher tensions than conventional approaches dictate. This distinguishes its tonal character and contributes to its powerful and complex sound.
The double bass, also known simply as the bass, is the largest and lowest-pitched bowed string instrument in the modern symphony orchestra. Similar in structure to the cello, it has four, although occasionally five, strings.
The guitar is a fretted musical instrument that typically has six strings. It is held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A plectrum or individual finger picks may also be used to strike the strings. The sound of the guitar is projected either acoustically, by means of a resonant chamber on the instrument, or amplified by an electronic pickup and an amplifier.
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 piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material. It is played using a keyboard, which is a row of keys that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. It was invented in Italy by Bartolomeo Cristofori around the year 1700.
The violin, sometimes known as a fiddle, is a wooden chordophone in the violin family. Most violins have a hollow wooden body. It is the smallest and thus highest-pitched instrument (soprano) in the family in regular use. The violin typically has four strings,, usually tuned in perfect fifths with notes G3, D4, A4, E5, and is most commonly played by drawing a bow across its strings. It can also be played by plucking the strings with the fingers (pizzicato) and, in specialized cases, by striking the strings with the wooden side of the bow.
An overtone is any harmonic with frequency greater than the fundamental frequency of a sound. In other words, overtones are all pitches higher than the lowest pitch within an individual sound; the fundamental is the lowest pitch. While the fundamental is usually heard most prominently, overtones are actually present in any pitch except a true sine wave. The relative volume or amplitude of various overtone partials is one of the key identifying features of timbre, or the individual characteristic of a sound.
String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
The hurdy-gurdy is a string instrument that produces sound by a hand-crank-turned, rosined wheel rubbing against the strings. The wheel functions much like a violin bow, and single notes played on the instrument sound similar to those of a violin. Melodies are played on a keyboard that presses tangents—small wedges, typically made of wood—against one or more of the strings to change their pitch. Like most other acoustic stringed instruments, it has a sound board and hollow cavity to make the vibration of the strings audible.
In music, inharmonicity is the degree to which the frequencies of overtones depart from whole multiples of the fundamental frequency.
A twelve-string guitar is a steel-string guitar with 12 strings in six courses, which produces a thicker, more ringing tone than a standard six-string guitar. Typically, the strings of the lower four courses are tuned in octaves, with those of the upper two courses tuned in unison. The gap between the strings within each dual-string course is narrow, and the strings of each course are fretted and plucked as a single unit. The neck is wider, to accommodate the extra strings, and is similar to the width of a classical guitar neck. The sound, particularly on acoustic instruments, is fuller and more harmonically resonant than six-string instruments. The twelve-string guitar can be played like a 6-string guitar as players still use the same notes, chords and guitar techniques like a standard 6-string guitar, but advanced techniques might be tough as players need to play or pluck two strings simultaneously.
The acoustic bass guitar is a bass instrument with a hollow wooden body similar to, though usually larger than a steel-string acoustic guitar. Like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned E-A-D-G, an octave below the lowest four strings of the 6-string guitar, which is the same tuning pitch as an electric bass guitar.
Piano acoustics is the set of physical properties of the piano that affect its sound. It is an area of study within musical acoustics.
Aliquot stringing is the use of extra, un-struck strings in the piano for the purpose of enriching the tone. Aliquot systems use an additional string in each note of the top three piano octaves. This string is positioned slightly above the other three strings so that it is not struck by the hammer. Whenever the hammer strikes the three conventional strings, the aliquot string vibrates sympathetically. Aliquot stringing broadens the vibrational energy throughout the instrument, and creates an unusually complex and colorful tone.
The Appalachian dulcimer is a fretted string instrument of the lute family, typically with three or four strings, originally played in the Appalachian region of the United States. The body extends the length of the fingerboard, and its fretting is generally diatonic.
The sarod is a stringed instrument, used mainly in Hindustani music on the Indian subcontinent. Along with the sitar, it is among the most popular and prominent instruments. It is known for a deep, weighty, introspective sound, in contrast with the sweet, overtone-rich texture of the sitar, with sympathetic strings that give it a resonant, reverberant quality. A fretless instrument, it can produce the continuous slides between notes known as meend (glissandi), which are important in Indian music.
Sympathetic strings or resonance strings are auxiliary strings found on many Indian musical instruments, as well as some Western Baroque instruments and a variety of folk instruments. They are typically not played directly by the performer, only indirectly through the tones that are played on the main strings, based on the principle of sympathetic resonance. The resonance is most often heard when the fundamental frequency of the string is in unison or an octave lower or higher than the catalyst note, although it can occur for other intervals, such as a fifth, with less effect.
The guitarrón mexicano (the Spanish name of a "big Mexican guitar", the suffix -ón being a Spanish augmentative) or Mexican guitarrón is a very large, deep-bodied Mexican six-string acoustic bass played traditionally in Mariachi groups. Although similar to the guitar, it is not a derivative of that instrument, but was independently developed from the sixteenth-century Spanish bajo de uña ("fingernail[-plucked] bass"). Because its great size gives it volume, it does not require electric amplification for performances in small venues. The guitarrón is fretless with heavy gauge strings, most commonly nylon for the high three and wound metal for the low three. The guitarrón is usually played by doubling notes at the octave, a practice facilitated by the standard guitarrón tuning A1 D2 G2 C3 E3 A2. Unlike a guitar, the pitch of the guitarrón strings does not always rise as strings move directionally downward from the lowest-pitched string (the 6th string from the lowest-pitched string, A2, is a perfect 5th below the Adjacent string E3).
Javārī, in Indian classical music refers to the overtone-rich "buzzing" sound characteristic of classical Indian string instruments such as the tanpura, sitar, surbahar, rudra veena and Sarasvati veena. Javari can refer to the acoustic phenomenon itself and to the meticulously carved bone, ivory or wooden bridges that support the strings on the sounding board and produce this particular effect. A similar sort of bridge is used on traditional Ethiopian lyres, as well as on the ancient Greek kithara, and the "bray pins" of some early European harps operated on the same principle. A similar sound effect, called in Japanese sawari, is used on some traditional Japanese instruments as well.
An experimental musical instrument is a musical instrument that modifies or extends an existing instrument or class of instruments, or defines or creates a new class of instrument. Some are created through simple modifications, such as cracked drum cymbals or metal objects inserted between piano strings in a prepared piano. Some experimental instruments are created from household items like a homemade mute for brass instruments such as bathtub plugs. Other experimental instruments are created from electronic spare parts, or by mixing acoustic instruments with electric components.
Experimental luthiers are luthiers who take part in alternative stringed instrument manufacturing or create original string instruments altogether.
