"Submediant" also refers to a relationship of musical keys. For example, relative to the key of C major, the key of A major is the submediant. Modulation (changes of key) to the submediant are relatively rare, compared with, say, modulation into the dominant, and give a feeling of relaxation. Susan McClary says that modulation to the lowered submediant (in C: Ab) represents a dream like state of escape.
