Systems and methods are provided performing autonomous tuning of a stringed instrument. Images of the stringed instrument are acquired by at least two cameras and processed to identify the location of a peg. A robotic peg actuator is then engaged to actuate rotation of a peg in order to rotate the peg to a tuned angular orientation, guided by feedback generated by processing acoustic signals recorded by an acoustic transducer while a string associated with the peg is agitated. In some example implementations, the cameras and peg actuator are rigidly mounted to a frame that is configured to support the stringed instrument during peg imaging and actuation. A robotic string actuator may be provided to facilitate vibration of the string during the tuning process. Multiple robotic peg actuators may be included for per-peg rotational actuation and/or a given peg actuator may be robotically translatable to actuate more than one peg.

A musical instrument tuning lever kit includes a handle with a first axis along its stem and a second axis defined by its grip, with an axial aperture at the distal end. A shaft component extending along a third axis, receivable within the aperture of the stem of the handle, includes means for attachment of a head component. The head has means for attachment to the shaft component at its first end and means for attachment of a tip component at its second end. The tip has a first end with means for attachment to the head component, and a second end with a socket extending along a fourth axis for turning a tuning pin of a musical instrument. The first and second axes define a first plane, the third axis of the shaft and fourth axis of the socket define a second plane angularly orientable to the handle plane.

The invention is a micro-tuning device for pianos and other keyboard-operated stringed musical instruments. A mass is secured to a single string or choir of strings in the musical instrument by an attachment device between the bridge and the agraffe, nut or V-bar, thereby reducing the speaking length and increasing the pitch of the string.

An improved piano tuning lever includes a handle with a loop or ring large enough to fit the fingers of a user's hand, thereby providing a grip around the perimeter of the loop or ring which is independent of the axis of the handle. The resulting grip affords improved ergonomics and may lessen stress in the user's wrist and hand when having to conform to various angles of the handle axis as the tuning lever is moved from tuning pin to tuning pin over the course of a piano tuning. The improved handle and loop or ring may be made any size or shape, symmetrical or asymmetrical and with its core being solid, hollow, or filled. Another embodiment of the piano tuning lever includes a spline designed to mate with an inventive piano tuning lever head having complementary splines.
