Musical instrument sound improvement structure

The present invention relates to the field of accessories for a stringed instrument, and more particularly to a tuning member that increases the tension of a stringed instrument string, which makes the vibration of the string more stable, and a tone-improving structure.

Stringed instruments allow the player to selectively press the string on a fret ooard, neck, fingerboard, etc., such as a guitar, ukulele, etc., at different points along the string, so that when the string is plucked at the same time Producing certain tones or notes, by which multiple chords can be used for continuous or simultaneous manipulation, the player can thus produce chords and melody within the original pitch range of a particular instrument, adjusting the entire instrument without permanent changes. The pitch allows the player to subsequently manipulate the strings of the instrument to temporarily generate chords and melody in different pitch ranges; the instrument is a stringed instrument, and the instrument string chord structure must be used to adjust the resonant length of each instrument string. Meet the pitch of each melody.

However, once the instrument is formed, its tone quality is determined, and it is difficult to change.
