Major thirds tuning Major thirds tuning Among alternative tunings for guitar, a major-thirds tuning is a regular tuning in which each interval between successive open strings is a major third ("M3" in musical abbreviation). Other names for major-thirds tuning include major-third tuning, M3 tuning, all-thirds tuning, and augmented tuning. By definition, a major-third interval separates two notes that differ by exactly four semitones (one-third of the twelve-note octave). The Spanish guitar's tuning mixes four perfect fourths (five semitones) and one major-third, the latter occurring between the G and B strings: This tuning, which is used for acoustic and electric guitars, is called ""standard""
Major thirds tuning This is never going to take the place of folk guitar, and it's not meant to. For difficult music, and for where we are going in free jazz and even the old be-bop jazz, this is a much easier way to play." Major-thirds tuning is closely related to minor-sixths tuning, which is the regular tuning that is based on the minor sixth, the interval of eight semitones. Either ascending by a major third or by descending by a minor sixth, one arrives at the same pitch class, the same note representing pitches in different octaves. Intervals paired like the pair
