Abstract

A five-string guitar is tuned in fifths to provide better sound. A five-string guitar is tuned in fifths to provide better sound by providing better harmonic separation of the notes played and by reducing "muddiness" or lack of clarity in the heard note. A number of realized embodiments enable the five-string guitar to accommodate a wide variety of stringed-instrument musical needs and preferences.
