Disclosed herein are various embodiments of devices and systems which may be reversibly coupled to a sound hole of a hollow-bodied stringed instrument for the generation of percussive musical sounds. Various embodiments herein disclosed comprise various means of reversibly coupling a percussive attachment with a musical instrument, and comprise adjustable device body lengths and angular orientations relative to the hollow body of musical instruments so as to allow percussive sound-generating elements to produce musical sounds from within a resonating chamber of the hollow-bodied instrument through interaction with an inner surface thereof.

A musical instrument includes a plurality of strings and a body. The body supports the plurality of strings on a first surface of the body. The body includes a groove formed in the first surface that extends linearly. The groove has a constant width and a constant depth.

A stringed instrument body includes a top body having a groove/shelf engagement structure, and a back body having a corresponding shelf/groove engagement structure that is engagable with the groove/shelf engagement structure of the top body. When the corresponding shelf/groove engagement structure is engaged with the groove/shelf engagement structure, a projecting portion of the groove/shelf engagement structure of the top body projects within the back body and contacts a corresponding recessed portion of the shelf/groove engagement structure of the back body.

A soundboard for a musical instrument is disclosed the soundboard having at least one layer of material. In some embodiments the material comprising carbon fiber, fibrous laminate material, resin or a plastic matrix and combinations thereof. At least one bracing structure is engaged to the at least one layer of material. The at least one bracing structure comprising at least one layer of honeycomb or shaped core and at least one sheet of material bonded to the honeycomb or shaped core.

A musical instrument, particularly a stringed instrument, has a structure that decouples the body of the player from all parts of the instrument which are indirectly responsible for the sound production for preventing the body of the player from damping the vibrations of the instrument. Instead of a top cover being the main source of indirect sound production, the musical instrument now has an annular plate which is positioned between covers. Any damping effect on the resonance of the annular plate is minimized by positioning a bridge on the annular plate to avoid any contact between the bridge and the top cover, and applying an acoustically decoupling layer between the covers and the annular plate. The covers provide protection against any damping effect of the player's body on the annular plate. This structure also minimizes the tendency of an acoustic feedback loop, 2 which may occur in the case of an electrically amplified stringed instrument.

A vibration plate for a musical instrument includes: a plate-shaped vibration plate main body that has a deformation anisotropy property; a first elongated reinforcing member disposed on a first face of the vibration plate main body, and that projects outwardly from the first face and extends along the first face in a direction that prevents the vibration plate main body from deforming; and a second elongated reinforcing member disposed on a second face of the vibration plate main body, and that projects outwardly from the second face and extends along the second face in the direction that prevents the vibration plate main body from deforming. As viewed from a thickness direction of the vibration plate main body, at least part of the first elongated reinforcing member overlaps with at least part of the second elongated reinforcing member.

The present invention relates to a musical instrument for producing a harmonious scale of musical notes. The instrument includes nine separate sound actuators each of which is configured to cause the musical instrument to generate a different frequency selected from the group of frequencies comprising 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz and 963 Hz, the musical instrument being configured such that physically manipulating the sound actuators causes the musical instrument to generate the frequency corresponding to the sound actuator manipulated. The invention is also directed at a system for—writing music to be played with a musical instrument incorporating the harmonious scale of musical notes as described above. The notation system includes a staff of five parallel and horizontal lines separated by four spaces, the first line indicating a first note of 174 Hz, the space immediately above the first line indicating a second note of 285 Hz, the second line indicating a third note of 396 Hz, the space immediately above the second line indicating a fourth note of 417 Hz, the third line indicating a fifth note of 528 Hz, the space immediately above the third line indicating a sixth note of 639 Hz, the fourth line indicating a seventh note of 741 Hz, the space immediately above the fourth line indicating an eighth of 852 Hz and the fifth line, indicating a ninth note of 963 Hz.
