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.

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