A storage case for musical accessories includes a bottom wall; an outer sidewall extending from the bottom wall, the outer sidewall and bottom wall defining an interior space; a divider wall extending from the bottom wall between a first location on the outer sidewall and a second location on the outer sidewall, the divider wall configured to divide the interior space into a first compartment and a second compartment; a first lid hingedly attached to the first compartment and configured to enclose the first compartment; and a second lid hingedly attached to the second compartment and configured to enclose the second compartment.

A foldable stringed instrument having a neck and/or body that may assume a reduced profile by folding an upper neck portion away from the playing position through the use of a translating bridge assembly and a translating truss assembly, wherein the foldable stringed instrument is capable of housing or otherwise being coupled to any of a variety of electronics or electrical components (e.g. a smart phone or tablet computer) having one or more applications (apps) for driving the operation, functionality and/or effects associated with the foldable stringed instrument.

An apparatus for improving technical ability related to the use of a musical instrument, in particular for finger exercise, comprising a bearing structure that can be mated to the back of the hand of a user by removable fastening means; the apparatus further comprises a movable component, constituted by one or more rings, each of which is designed to be associated with a phalanx of a finger of the hand, each ring being connected to the bearing structure by elastic means; the apparatus finds application both in the development of technical ability related to the use of any musical instrument, with particular effectiveness on stringed instruments, and in the medical field in rehabilitation therapy for use of the hand.

A system consisting of one or more components that enables the playing of a stringed instrument by contacting one or more strings of the instrument in such a manner as to cause the frequency emitted to change when the string is mechanically agitated so as to vibrate.

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 insert within the slide body defining an inner wall and creating a space between the slide body and the insert and further includes liquid within the space between the slide body and the insert to further affect the sound produced by the instrument when the outer wall is applied to the strings. A removable collar may be included with an aperture or opening that may vary in size to accommodate multiple users. Liquid may be selectively sealed between the slide body and the insert and be changed as required.

A string stretching apparatus, system and method are described. The string stretching apparatus may include lower and upper raised portions at an outer surface of a body of the stretching apparatus. A portion of the body of the string stretching apparatus may be placed in contact with a neck of a musical instrument. The lower and upper raised portions may be configured to extend outwardly to extend a distance between the neck of the musical instrument and at least one string of the musical instrument. The string stretching apparatus may be manipulable in a longitudinal direction of the neck of the musical instrument, and either or both of the lower and upper raised portions may be configured to rotate, in order to increase or decrease string tension.
