Devices and systems for assisting with playing a plucked string instrument are provided. In some exemplary implementations, a device for providing assistance to operating a plucked string instrument may include a key positioned above a string of the plucked string instrument and attachable to a fretboard of the plucked string instrument. The key may be configured to apply a force to the string when the key is depressed. The device may also include a magnet located under the key and configured to generate a magnetic field that reduces an amount of force required to depress the key without the magnet. The device may be implemented in a fretboard cover or may be integrated into the plucked string instrument.

The disclosure seeks to describe a system and method for transmitting acoustic energy to a listener. The system includes a flexible pick-up, at least one acoustic energy transmisson member and at least one audio output. The flexible pick-up has an interior, at least one opening, and is configured for compression against strings of a stringed instrument for direct energizing by the strings. The at least one acoustic energy transmission member has a first end coupled to the interior of the pick-up through the opening. The at least one audio output is mounted on a second end of the energy transmission member and is configured to transmit acoustic energy therefrom to a listener.

The fretboard system provides a replaceable fretboard with customized placement of frets along the fretboard for a stringed instrument. A configuration of magnets on the neck of the stringed instrument secure the fretboard to the stringed instrument. The magnets attract a metallic underside, such as a sheet metal, of the detachable fretboard. A separating layer, including but not limited to a layer of wood or other composite material, separates the magnets from the sheet metal. At least one, preferably two or more, reinforcing members extend longitudinally along the neck of the stringed instrument to reinforce the neck.

An auxiliary device coupled to a stringed instrument for producing chords is disclosed. The auxiliary device comprises a housing. The housing comprises a plurality of buttons and a plurality of actuators coupled to the plurality of buttons. Further, the auxiliary device comprises a rim coupled to the housing. In order to couple the auxiliary device to the stringed instrument, a neck of the stringed instrument is placed between the housing and the rim, such that the plurality of actuators are made to come in contact with stings of the stringed instrument. The plurality of buttons is pressed to operate the plurality of actuators. When operated, the plurality of actuators is made to depress to strum the strings to produce a chord.

A musical instrument slide for a stringed instrument and a method of manufacturing the same includes a slide body defining an outer wall, the outer wall configured to affect sound produced by the instrument when applied to one or more strings of the instrument. The slide includes an inner wall within the slide body creating a space between the slide body and the inner wall and further includes fluid, slurry or the like within the space between the slide body and the inner wall, which may further affect the sound produced by the instrument when the outer wall is applied to a string. A removable collar may be included with an aperture or opening that may vary in size to accommodate multiple users.

Method and apparatus for a capo for a fretted instrument with a plurality of strings. The capo base having been bent into a u-shape, with a barrier of Velcro on the bottom side where the capo contacts on the strings, protecting them, also said Velcro will not let the strings move laterally, out of tune. Having also Velcro on the inside of the rear of the capo to protect the finish on the instruments' side. The capo covers two adjacent frets, pressing the body of the capo to the frets and not to the fretboard, eliminating excessive string sharpness. The capo having a thumbnut on the bottom to tighten the capo down on the strings.

A learning device assembly for a stringed instrument includes one or more light strip members, at least one light element in the one or more light strips, a connecting member electrically connected to the one or more light strip members, a controller electrically connected to the connecting member and configured to electrically drive the at least one light element in the one or more light strip members and a computing device communicatively coupled to the controller, the computing device configured to be programmed with or more music arrangements and enable the controller to illuminate one or more of the at least one light element in the one or more light strip members to enable a playing of one or more music arrangements on the stringed instrument.
