A musical instrument clamp system which includes a bracket assembly having a first end and a second end, a cradle assembly, a clamp assembly operatively connected to the first end of the bracket assembly, wherein the clamp assembly is also removably attached to the cradle assembly, an extension assembly having a first end and a second end, wherein the first end of the extension assembly is operatively connected to the second end of the bracket assembly, a hook assembly, wherein the hook assembly is operatively connected to the second end of the extension assembly, and a musical instrument removably retained on the hook assembly.

A string instrument has a neck attached to a body and extending outwardly therefrom. The body has a top plate joined to a bottom plate by a continuous rib forming an interior volume therebetween. A tailpiece is joined to the body. The tailpiece has tubular string bores. Each string bore has an entrance for receiving a string therein and an exit from which the string emerges and extends to the neck. At least one the exits has a cross-sectional shape in which a length of a major axis of the cross-sectional shape is greater than a length of a minor axis of the cross-sectional shape.

A self-locking tuner is used to tune the strings of a musical instrument. The self-locking tuner is disposed in a headstock of the stringed musical instrument. The self-locking tuner has an inner string post, outer string post disposed over the inner string post, locking pin extending above the inner string post and through the outer string post to the opening, and insert disposed around the outer string post. Alternatively, a cast housing is disposed around the outer string post with a stop to unlock a string. The string extends through an opening in the outer string post. The insert or cast housing has a stop to unlock the string. The outer string post has a rotational stop which contacts the stop to unlock the string. The insert is disposed in a headstock with the tab disposed in a slot formed in a surface of the headstock.

An apparatus for emulating a variety of string instruments with a variety of configurations in order to measure the resulting, actual tension of a string on that instrument. The tension may be measured in real-time.

The present invention relates to an educational string instrument comprising: a body provided with a head portion and a bottom portion; a nut installed on the head portion; a saddle installed on the bottom portion; a plurality of fixing parts installed on an outer side of the nut of the body; a plurality of tuning devices installed on an outer side of the saddle of the body; a plurality of strings supported by the fixing parts and the tuning devices and installed to be spaced apart from the body by the nut and the saddle, and a single fret installed to be inwardly spaced apart from an inner side of the nut to form a fingerboard part and functioning for raising an original note of the string by a semitone.

A capo for a musical instrument with a neck and a plurality of parallel strings disposed above the neck. The capo includes a U-shaped yoke having first and second branches, and a clamping bar assembly pivotally attached to one of the yoke branches. The clamping bar assembly includes a main bar body and a plurality of separate string clamp members, which are operatively attached to the main bar body and formed of a substantially rigid plastic material. The clamping bar assembly also includes one or more flexibly resilient cushion members provided between the string clamp members and the main bar body. The main bar body may have sockets formed therein which receive individual cushion members and portions of the string clamp members. Alternatively, the string clamp members may share a single elongated cushion member, and may have passages formed therethrough allowing for slidable mounting on a solid main bar body.
