Submediant
In music, the submediant is the sixth degree (
) of a diatonic scale. The submediant ("lower mediant") is named thus because it is halfway between the tonic and the subdominant ("lower dominant")[1] or because its position below the tonic is symmetrical to that of the mediant above.[2] (See the figure in the Degree (music) article.)
In the movable do solfège system, the submediant is sung as la in a major mode, le or lo in do-based minor and fa in la-based minor. It is occasionally called superdominant,[3] as the degree above the dominant. This is its normal name (sus-dominante) in French.
In Roman numeral analysis, the triad formed on the submediant is typically symbolized by "VI" if it is a major triad (the default in a minor mode) and by "vi" if it is a minor triad (the default in a major mode).
The term submediant may also refer to a relationship of musical keys. For example, relative to the key of C major, the key of A minor is the submediant. In a major key, the submediant key is the relative minor. Modulation (change of key) to the submediant is relatively rare, compared with modulation to the dominant in a major key or modulation to the mediant (relative major) in a minor key.
