The present application discloses a clamping mechanism for a guitar capo, including an upper clamp (1) and a lower clamp (9). A slider rail (2) is fixedly installed inside the upper clamp (1), a rebound torsion spring fixing pin (3) is fixedly installed inside the slider rail (2), and a rebound torsion spring (4) is fixedly installed inside the slider rail (2) by the rebound torsion spring fixing pin (3). A crank hinge (6) is fixedly installed inside the slider rail (2). The clamping mechanism of the guitar capo is provided with the lower clamp (9), and the cam structure on the right side of the lower clamp (9) is stuck and cannot move the self-locking slider (7) in the opposite direction, thus the lower clamp (9) cannot rotate in the opposite direction, thereby achieving locking effect and completing locking and clamping. By providing with the unlocking handle (5), the unlocking handle (5) drives the self-locking slider (7) to slide to unlock the locking of the cam mechanism of the lower clamp, thereby effectively achieving the effect of quickly installing the capo on the guitar strings and improving the self-locking effect of the capo.

A barre chord device can include a strip of rubber, elastomeric or other resilient material with heat formed creases and protruding shims. A guitar player attaches the strip at discrete places to the index finger of his fretting hand. When the guitar musician performs a barre chord, the strip concentrates barre force to the strings. Shims press into the concave mid-finger keeping the strip straight on a string side to provide uniform barre pressure. Muscular effort is minimized. Creases cause the strip to fold neatly to a thumb side when the index finger is curled to perform non-barre chords and scales.

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.
