C# Class Midi.Scale

A scale based on a particular tonic.

For our purposes, a scale is defined by a tonic and then the pattern that it uses to ascend up to the next tonic and then descend back to the original tonic. The tonic is described with a NoteFamily because it is not specific to any one octave. The ascending/descending pattern is provided by the Pattern nested class.

This class comes with a collection of predefined patterns, such as Scale.Major and Scale.HarmonicMinor.

Public Methods

Method	Description
Contains ( Pitch pitch ) : bool	Returns true if pitch is in this scale.
Equals ( System obj ) : bool	Value equality.
GetHashCode ( ) : int	Hash code.
Scale ( Midi.Note tonic, ScalePattern pattern ) : System	Constructs a scale from its tonic and its pattern.
ScaleDegree ( Pitch pitch ) : int	Returns the scale degree of the given pitch in this scale.
ToString ( ) : string	ToString returns the scale's human-readable name.
operator ( ) : bool	Inequality operator does value inequality because Chord is immutable.
