Detailed Description

Describe a chord.

A chord is characterized by a base note, a duration (fraction of the measure) and some alteration.

Member Enumeration Documentation

enum Chord::ChordType

strong

Describes the type of the third note in the chord.

Enumerator
Minor	Describes a minor chord, meaning that the first third is a minor third.
Major	Describes a major chord, meaning that the first third is a major third.
Sus4	Describes a suspended fourth chord, meaning that the third is replaced by a forth.
Sus2	Describes a suspended second chord, meaning that the third is replaced by a second.
Dim	Describes a diminished chord, composed of a minor third and a diminished fifth.
Aug	Describes a augmented chord, in which the fifth is augmented.

enum Chord::SeventhType

strong

Describes the Type of the fourth note of the chord.

Describe the nature of the chord.

By default, a chord is a triad composed of a base note, a third, and a fifth over it.
