The musical instrument strings and a method of instruction comprise a set of strings, each string having colored markings along its length, each mark indicating a note sounded when the string is played at the mark. Additional notes are similarly marked along each string, each of the musical notes having a unique color. Additional markings along the neck of the instrument and at open string positions correspond to the colored markings of the strings. Music notation having colored notes corresponding to the colored markings of the string facilitates a student in learning to play a musical instrument by matching the colored notes to the colored markings on the strings.
