Abstract
A musical instrument tuning system disposed and displayed upon a string instrument. The tuning system includes a first indicator displayed upon the surface of the string generally having three indicia zones representing a pitch alignment zone, a string tension load warning zone, and a zone indicating that the string is below pitch. The first indicator may take the form of a coating applied to the external surface of the string providing a plurality of visually discernable bands. A second indicator is displayed upon the instrument to provide a visual reference for the string markings. Rotatable displacement of a peg to which the string is fixedly secured provides for linear displacement of the bands with respect to the second indicator. Thus, rotation of the peg resulting in alignment of the tension load warning zone with the second indicator alerts the user that the string may rupture upon the addition of further tension. Opposite rotation of the peg resulting in alignment of the low pitch zone marking on the string with the second indicator demonstrates to the user that the string is tuned below pitch.
