Abstract: A stringed-instrument slide (100) which is a truncated conical shell with the narrower end at the top (110) and with a roughly semi-circular cut-away (150) along the base (130), so a substantial portion of the mass is below the level of the finger-palm joint. The mass of the slide (100) is predominantly born by the region of contact of the slide (100) with the palm (98) rather than along the pinky (99) so the slide (100) has the sensation of being “balanced” and relatively “weightless” on the pinky (99) and the pressure applied by the pinky (90) corresponds closely to the actual pressure of the slide (100) on the strings, and the forces and torques required to move the slide (100) onto and off of the strings is reduced, thereby facilitating play, particularly rapid and/or nuanced play.

Abstract: A guitar slide has a core that consists essentially of a metal composition which is susceptible to the formation of nitrides and carbides of the metal composition upon proper exposure to carbon and nitrogen.

Abstract: A musical instrument slide including a body portion and a light source. The light source includes a switch for selective activation, enabling the slide body to emit light when activated. As the musician moves the slide across the strings as the instrument, such as a guitar, is played, a visual effect is created by the movement of the light. The body portion preferably is constructed of a material to pass light therethrough, and can be either wholly or partially clear or translucent, or a combination of both. Alternatively or in addition to the light source, the slide body can include an eccentric motor that causes the slide body to vibrate. This vibration, in turn, causes vibration of the guitar strings, or other string instrument, as the slide is positioned on the strings, or moved along the strings, by the musician.

Abstract: Slide bars for use with all types of musical instruments and in particular guitars played in either an overhand or an underhand style. One version of the slide bar consists of a tapered bar with a ring attached to the small diameter end of the bar. The slide is placed on a finger like a ring such that the slide can be engaged to contact the strings yet still permit use of all the fingers on the plucking hand. The slide can also be easily swung out of engagement with the strings and maintain the useability of the fingers on the plucking hand. The bar can be magnetic to reduce the need for players to develop exact pressure techniques. Another version of the slide consists of a hollow cylindrical tube in which magnetic or non-magnetic weight units are placed to emulate the same effect of solid tapered bars. Another version of the slide consists of a magnetized cylindrical tube that provides the advantages of controlling pressure on the strings similar to the magnetic tapered bar.
