  • Publication number: 20030094087
    Abstract: A musical system for stringed instruments based on tuning in fifths in conjunction with component control reduces dissonance and discord while increasing harmony and consonance. In a stringed instrument, the main music-making portion of the string serves to drive the other non-music-making portions or supporting portions of the string. This is particularly true at the end of the string past the stop point toward the fixed end and upward past the nut towards the turnable post controlled by a key. By appropriately selecting and providing adjustment for the stop point, as well as the length of the strings past the bridge, less dissonance arises from the individual string as it is played. A string retainer or the like, as well as a compound head, may serve to provide adjustable or selectable means by which tension on a plurality of strings may be adjusted to provide uniform tension between individual strings. Tuning in fifths provides inter-string harmony.

  • Publication number: 20030000365
    Abstract: A stringed instrument has a body, a longitudinal neck attached to the body and extending therefrom, and strings extending between the body and a free head end of the neck, the strings attached so that they generate a tensile force tending to deform the neck. To prevent deformation of the neck, it receives a rigid reinforcing body provided with a groove that extends from a first end of the body and terminates at a distance from the opposite second end, so that the rigid body has a grooveless end region and a grooved end region. The grooved end faces the body of the stringed instrument. The grooveless end region and an upper part of the grooved end region are fixed to the top side of the instrument neck along their entire lengths, whereas a lower part of the grooved end region is detachably secured to the neck and generates a force counteracting the tensile force to minimize the deformation of the neck.

  • Patent number: 6441294
    Abstract: The instant device provides a method for enhancing the sound of any acoustic/electric guitar and other musical instrument by electronically oscillating and manipulating the sound emitted by the guitar or other instrument. The prior art utilizes a manually activated processor that when used, in conjunction with a guitar and sound amplifying device, is capable of creating a broad range of sounds. The processor has customarily been located upon the floor and is activated by a foot pedal. This presented method replaces the prior art pedal processors and the need to be physically in proximity to the processor to activate the pedal and the processor. It accomplishes this by providing electronic means integral with a guitar strap whereby upward and downward movements of the guitar neck or guitar body activate the electronic means creating variable electronic signals to an amplifier or other amplifying device enabling a wide range of distorted sounds to be emitted from the guitar.

For playing in a standing position a support strap is attached to the end of the tail. The tail may be shaped to have a slight taper and squared-off end so as to balance and complement a similar but more elongated design of the "headless" neck portion.

  • Patent number: 6069306
    Abstract: The present invention relates to musical instruments and methods and apparatus for producing notes of a musical scale with real strings. More particularly, it relates to the division by frets, of the fingerboard, or neck, of a fretted stringed musical instrument, to obtain a desired musical scale with a specific set of strings. One embodiment of the invention is described in which the 12-tone equal-tempered scale is accurately produced on a guitar with steel strings having sufficient bending stiffness to cause audible intonation errors inherent in steel-stringed guitars of prior art. According to another embodiment of the invention, the musical scale is additionally tempered to approximate the 12-tone, equal-tempered scale while minimizing audible beats that occur when playing intervals and chords due to inharmonic frequency components inherent in tones generated by vibrating guitar strings. Manufacturing methods with respect to wound strings, and with respect to boundary conditions, are also explained.

  • Patent number: 6051765
    Abstract: A guitar neck is formed with a protruding trapezoidal heel which extends into a pocket formed at the neck end of the body. The tendency of the strings to bend the neck is counteracted by a truss rod assembly which is positioned in a contoured channel formed in the neck beneath the fingerboard. The assembly has a threaded stainless steel rod which extends through an aluminum U-channel, with one end extending beyond the U-channel beneath and adjacent the first fret of the fingerboard, where it is fixed to the U-channel, and the other end extending out of the U-channel adjacent the neck-body joint, where an adjustable hex nut is threaded on the rod which bears on a washer. Two cylindrical spacers are fixed to the rod within the U-channel at positions upward of the neck joint which serve to hold the rod in the center of the U-channel between the U-channel legs, and also spaced outwardly from the base of the U-channel to thereby cause the rod to bow away from the base into the contoured channel in the neck.

  • Patent number: 6051766
    Abstract: A stringed instrument such as a hollow body guitar has a neck portion that extends under the tail of the fretboard. The body of the instrument has a pair of recesses which mate with respective tail and heel surfaces on the neck portion. Spacers are placed in the recesses in order to adjust the spacing and angle of the neck portion relative to the instrument's body. If the neck and body are connected to each other by bolts, then any misalignment between the neck and body can be cured by removing the bolts, replacing the spacers with spacers of a different thickness and/or wedge shape, and replacing the bolts. Additional structural components can be added to the neck and inside the body of the instrument in order to further enhance its structural integrity.

  • Patent number: 6034309
    Abstract: A method of manufacturing an acoustic guitar having a pre-finished resin laminate soundboard, sidewall and backboard. The contoured sidewall of the guitar is provided by a relatively flexible strip of the laminate material which is formed into a loop-shaped preform before being positioned within a multi-part fixture. The fixture is closed on the preform to conform the shape of the preform into a contoured shape. Subsequently, ribbon linings, a soundboard and a backboard are adhesively secured to the preform to complete the assembly of the hollow body portion of the acoustic guitar. Since he laminate material is pre-finished, numerous time consuming finishing steps typically preformed in known methods are eliminated.
