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.

A resonator for stringed musical instruments with a resonance chamber, is suitable for both bowed and plucked stringed instruments with a resonance chamber which aims at increasing the volume as well as the sound projection and timbre quality of the instrument, thus improving its performance, by eliminating the residual air which remains inside the sound box. For that purpose, the resonator comprises a tube with a beveled inlet end and an exit end with an end-button, one or more holes at various angles to reduce the air intake pressure, together with one or more compressor tubes included inside which interfere with the balance variation of air pressure and speed towards the exit across a reed.

A stringed musical instrument is disclosed comprising a first tube including a body portion having a bottom end and a top end, and a neck portion with a first end extending longitudinally from the bottom end of the body portion, and a second end. A first string support is connected to the second end of the neck portion, and includes a peg box supporting a plurality of tuning pins. A plurality of musical instrument strings extend from the body portion to the tuning pins. The instrument also includes a bridge with a body-contacting portion configured to engage with the body portion, and a string-contacting portion configured to engage with the plurality of strings, and a second tube extending outwardly from the top end of the body portion, forming a chin rest. Corresponding systems and methods also are disclosed.

An electromagnetic multi-function multi-purpose chordophone musical instrument upon which any form or style of music may be played in any position by a performer standing or seated, in a fixed location or moving throughout a performance venue. The player may initiating the vibrations of each string, any combination of strings, or all of the strings with a plectrum or the fingers of one or both hands, singly or in any combination and such vibrations will continue until their eventual natural termination unless damped and/or muted by the player using the fingers or the palm of one or both hands singly or in any combination. The shape and style of the rigid frame of the instrument is not limited by the need for frets, a fretboard, or keys.
