Line 1:

~~The~~ '''[[arto and tendo]]''' or '''extraclassical tonality ~~system~~''' ~~is a~~ tonality ~~system built from~~ ultramajor (~~called~~ "tendo") and inframinor (~~called~~ "arto") triads. Because these chords share many of the same properties as major and minor triads, the extraclassical harmonic system resembles the conventional diatonic system in many ways, however, it also has many distinct characteristics that make it sound nothing like normal major and minor chords.

'''A[[arto and tendo|rto and tendo]]''' or '''extraclassical tonality''' refers to tonality that uses ultramajor (or "tendo") and inframinor (or "arto") triads. Because these chords share many of the same properties as major and minor triads, the extraclassical harmonic system resembles the conventional diatonic system in many ways, however, it also has many distinct characteristics that make it sound nothing like normal major and minor chords.

The name "extraclassical" derives from the mediants' position outside the range of the classical and standard diatonic mediants.

Line 6:

Arto and tendo triads are the same shape as minor and major triads, but with a more extreme difference between the thirds. This can be characterized in terms of interval [[latitude]] with respect to the perfect fifth, wherein arto and tendo have latitudes more extreme than major and minor.

An arto triad results by flatting the third of a minor triad by approximately one [[quarter tone]], producing an inframinor third of about ~~235-255~~{{cent}}.

An arto triad results by flatting the third of a minor triad by approximately one [[quarter tone]], producing an inframinor third of about 235–255{{cent}}.

A tendo triad results by sharping the third in a major triad by approximately one quarter tone, producing an ultramajor third of about ~~445-465~~{{cent}}.

A tendo triad results by sharping the third in a major triad by approximately one quarter tone, producing an ultramajor third of about 445–465{{cent}}.

The tendo chord is considered to be more consonant than the arto chord, just as the major chord is considered more consonant (if only slightly) than the minor chord. Also, both chords are only slightly more dissonant than the normal major and minor chords.

More generally, [[User:VectorGraphics/The spectrum of mediants|medials]] of a fifth with a latitude of ~~~25-30~~ degrees may be considered arto and tendo thirds, where the outer bound (and one of the most common tunings) is [[3edf]], corresponding to slendric.

More generally, [[User:VectorGraphics/The spectrum of mediants|medials]] of a fifth with a latitude of ~25–30 degrees may be considered arto and tendo thirds, where the outer bound (and one of the most common tunings) is [[3edf]], corresponding to slendric.
