For the minor side of any interval class, swap "major" and "minor", "sub" and "super/supra" (super applies only to major and unqualified intervals, other types use supra), "ultra" and "infra", and "arto" and "tendo" (in all senses). | For the minor side of any interval class, swap "major" and "minor", "sub" and "super/supra" (super applies only to major and unqualified intervals, other types use supra), "ultra" and "infra", and "arto" and "tendo" (in all senses). | ||
For tritones, start at the semi-octave. If the semioctave exists in the scale, label it "neutral tritone", otherwise label the two closest intervals "artoneutral tritone" for the smaller and "tendoneutral tritone" for the larger. Label the sharpest tritone interval flatter than the neutral or artoneutral tritone "narrow tritone" (and label its complement "wide tritone"). If the interval closest to 565 cents has not already been labelled as a tritone, label it a "subtritone". If there are intervals between the subtritone and narrow tritone, label "grave tritone" if only 1 interval and "grave tritone" (for the smaller) and "small tritone" (for the larger) if there are two. Label the tritone interval one step smaller than the subtritone the infratritone. Similarly, do the same thing for fourths and fifths with the best 4/3 and 3/2 (and checking for n +- 35c rather than specifically 565c), but you won't need the artoneutral/tendoneutral case. | |||

For unisons, the term "diesis" is used in place of "major unison" and "counterdiesis" in place of "minor octave"; "comma" is "submajor unison" and "countercomma" is "supraminor octave". | For unisons, the term "diesis" is used in place of "major unison" and "counterdiesis" in place of "minor octave"; "comma" is "submajor unison" and "countercomma" is "supraminor octave". | ||
