Abstract:

Systems and methods for providing navigational marks on a fingerboard of a stringed instrument are provided. An example system may allow enhanced navigating of a player on the fingerboard of the stringed instrument. The system may comprise the fingerboard of the stringed instrument. Strings may be attached to the instrument over the fingerboard. A note may be produced by stimulating a part of a string associated with the note. The part of the string may be called a note location on the fingerboard. The navigational marks may be disposed on the fingerboard in association with the strings to mark note locations on the fingerboard and thus facilitate finding the note location. The navigational marks may include a plurality of types, with each type associated with a note of an octave and having a specific shape.
