The '''quality''' of an [[interval]] is its relative [[Interval size measure|size]] compared to similar intervals. Commonly used terms for qualities include ''major'', ''minor'', ''perfect'', ''augmented'', and ''diminished''.


The '''relative quality''' of an interval is defined with relation to the [[scale]] in which it is used in context, while its '''absolute quality''' is defined with relation to a fixed scale independent of the context in which it is used, usually the [[5L 2s|diatonic]] scale.
The '''relative quality''' of an interval is defined in terms of the ambient [[scale]] where it occurs, while its '''absolute quality''' is defined based on a fixed scale independent of the context in which it is used, usually the [[5L 2s|diatonic]] scale.


The concept of quality can also be expanded to chords. Chord qualities are related to the qualities of the component intervals that define the chord.
