The Autoharp Keyboard Mechanism is engaged with an autoharp having strings. Octave bars having piano-like keys are slidingly engaged with pins extending from the top surface of the autoharp and are located above the strings. Damping brackets are also slidingly engaged with the pins and are located beneath the octave bars and beneath the strings. Coil springs are arranged around each of pins and are located beneath the octave bars and the damping brackets. Adjustable length spacers are engaged with the octave bars and with the damping brackets, one at each end of the octave bars and damping brackets. The adjustable length spacers are located between the octave bars and the damping brackets, and are engaged with the octave bars using threads. Holders are configured to retain the octave bars on the pins.

A table stringed musical instrument includes string fastening members in an instrument structure. The string fastening members receive and fasten strings to the instrument structure. The instrument is a free stringed musical instrument configured for one or more, advantageously at least two or four or more players so that the string fastening members are grouped for at least two, advantageously at least four or more physically separate groups and additionally so that the strings to be received and fastened are thereby grouped for at least two or four or more separate groups and thereby for at least two or four or more different player positions. The first group of the string fastening members receives the first group of strings. The second group of the string fastening members receives the second group of strings, etc. The strings of the first group differ from those of the second group.

Disclosed is a stringing device configured for facilitating stringing of a stringed instrument having a rotatable axle vibrato. The stringing device is an elongate article having an inner surface and an outer surface. The inner surface is configured for mating with an axle of a rotatable axle vibrato. The outer surface has a plurality of openings of corresponding string passages, where each string passage facilitates the passage of strings from the outer surface through the stringing device and extending out from the inner surface. The plurality of openings optionally each have an eyelet seat configured to retain an eyelet of a string. Methods of using the stringing device are also disclosed.

This invention, a key-changing apparatus for stringed musical instruments, automatically sets all the strings to the necessary flats and sharps for any key signature selected. This allows musicians, particularly novices, to play musical scores in any key signature without having to remember to flatten or sharpen all the multiple notes required by the key signature.
