Major-thirds (M3) tunings are unconventional open tunings, in which the open strings form an

; in M3 tunings, the ''augmented'' fifth replaces the ''perfect'' fifth of the major triad of conventional open-tunings. Consequently M3 tunings are also called (open) ''augmented-fifth tunings'' (in French "''La guitare #5, majeure quinte augmentée''"). Unfortunately, the open augmented-chord sounds dissonant to audiences who are accustomed to standard tuning.
