Pitch Reference Number Enumeration Reference

Number

public enum Number : DiatonicIntervalNumber

The number of a UnorderedDiatonicInterval.

Cases

perfect(_:)
Imperfect unordered interval ordinals (e.g., unison, fourth).
Declaration
Swift

case perfect(Perfect)
imperfect(_:)
Perfect unordered interval ordinals (e.g., second, third).
Declaration
Swift

case imperfect(Imperfect)


                    
                    
                    inverse

Undocumented

Declaration

Swift

public var inverse: UnorderedDiatonicInterval.Number { get }

steps
The amount of diatonic steps represented by this UnorderedIntervalDescriptor.Ordinal.
Declaration
Swift

public var steps: Int { get }

Initializers

init(steps:)
Createss a UnorderedDiatonicInterval with the given amount of steps.
Declaration
Swift

public init?(steps: Int)
init(_:)
Creates an UnorderedDiatonicInterval with the given ordered interval.

In the case that the ordered interval is out of range (e.g., .fifth, .sixth, .seventh), the .inverse is converted into an unordered interval (e.g., a .seventh becomes a .second).
Declaration
Swift

public init(_ ordered: DiatonicInterval.Number)

Type Methods

distanceToIdealInterval(for:to:)
Declaration
Swift

public static func distanceToIdealInterval(for steps: Int, to interval: Double) -> Double
Return Value

The distance from the given interval to the ideal interval for the given amount of steps.
