ABSTRACT:
A musical instrument tuning system adapted to be mounted on a string instrument. The tuning system provides a visual indication to repeatedly aid in the proper tuning of a set of strings. Additionally, the tuning system gives a visual indication when a string is tension loaded to or near the rupture point. Further, the tuning system indicates when a string is below pitch after a reference point is set to provide proper tuning of a particular string. The tuning system mounted on the instrument pegboard includes a first decalcomania having three indicia zones representing a proper tuning zone, a string tension load warning zone and a zone indicating the appropriate string is below pitch. A second decalcomania mounted on a peg has indicia which is aligned with the first decalcomania tuning zone. Rotation of the peg resulting in alignment of the peg indicia with the tension load warning zone indicates a warning to the user that the string may rupture. Opposite rotation of the peg resulting in alignment of the peg indicia with the below pitch zone indicates that the string is not properly tuned.
