Enum persichetti::primitives::IntervalQuality

pub enum IntervalQuality {
    Diminished(usize),
    Augmented(usize),
    Minor,
    Major,
    Perfect,
}

Represents a chromatic alteration up or down that is applied to a pure IntervalSize.

Similar to Accidental, Diminished or Augmented are zero-indexed.

Due to a quirk of nomenclature, the value of Diminished(n) will vary depending on whether an interval is Perfect or Major. For example, a diminished fifth has an alteration of −1, but a diminished third has an alteration of −2.

Quality	Size	Chromatic Alteration
Major	Second, Third, Sixth, Seventh	0
Minor	Second, Third, Sixth, Seventh	−1
Perfect	Unison, Fourth, Fifth	0
Diminished(N)	Second, Third, Sixth, Seventh	−(N+2)
Diminished(N)	Unison, Fourth, Fifth	−(N+1)
Augmented(N)	All Intervals	N+1

impl IntervalQuality

pub fn from_chromatic_span(size: &IntervalSize, span: isize) -> IntervalQuality
