Embodiments of a capo and fretting component are described. In certain embodiments, the fretting component is threaded onto a crossbar configured to overlie the instrument strings when in use and to pivot with respect to the crossbar so as to contact and press the strings against a fret on the instrument neck. The fretting component is offset with respect to the attachment mechanism of the capo, allowing the attachment mechanism to be offset on the neck of the instrument from where it would normally be positioned to achieve a comparable fretting effect.

A tuning apparatus for a stringed musical instrument is provided. The apparatus includes a dual-action cam clamp assembly and a plurality of string-contacting members with easy-to-adjust rocker arms. The dual-action cam clamp assembly removably attaches to a desired longitudinal position on the instrument's neck. Each of the string-contacting members is rotatably supported by a rocker arm shaft, and the easy-to-adjust rocker arms are adapted to rotate about the longitudinal axis of a two-part shaft of the clamp assembly independently of the other string-contacting members. Each member also adjustably impinges upon and urges a given string or course thereof on the instrument toward a user-selectable one of three different longitudinal positions on the neck's front surface, these positions including a home position, a home−1 position, and a home+1 position.

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.

The present utility model discloses a force adjustable spring-clamp capo, comprises a string-engaging arm and a damping arm, the string-engaging arm and the clamping arm are hinged together by a composite pressing rivet, wherein a pressure adjustment mechanism is further arranged in a middle of the clamping arm, including: a pressure spring, a regulation screw and a regulation nut, by the pressure adjustment mechanism, a collapsing length of the pressure spring is adjusted, making the force of the spring change (Hooke's law), which makes the clamping force of the capo adjustable, it can also be operated by a single hand of a player as the spring-damp capo, thus owns a simple and easy operation, making a player be able to adjust to a best clamping force according to a requirement of the instrument thereof, to achieve a role of a tune transfer assistance perfectly. By a planar thrust bearing embedded in the regulation nut, the present utility model further reduces the resistance generated by the friction between the regulation nut and the clamping arm greatly, thus simplifies the operation of a force adjustment, and achieves the purpose of effort saving.

A capo for a stringed musical instrument is clamped on the neck of the instrument and has a flexible portion that is pressed against the strings between frets to change the tone of the instrument. The flexible portion may comprise various materials including a vessel wall structure filled with a fluid. Also, the flexible portion may comprise a silicone rubber.

A musical instrument accessory with a capo carrying an adjustable connector in turn carrying a screen receiving fixture. When the capo is clamped to the neck of a guitar at a first position, the screen receiving fixture may be arranged and oriented for convenient viewing of a screen carried therein by the guitar musician. When moved to second position, viewing the screen necessitates re-orientation of the screen receiving fixture to accommodate geometry of the second position, which re-orientation is conveniently carried out by re-orientation of the adjustable connector.
