The term "submediant" refers to the sixth scale degree in a musical scale. In the context of the major scale, it is the note that is a third below the tonic, or the first note of the scale. For example, in the C major scale, the submediant is A. This note plays a significant role in harmony and can create a sense of tension or resolution in music. In music theory, the submediant is often used to form chords, particularly the submediant chord, which is built on the submediant note. This chord can add depth to a composition and is commonly found in various genres. Understanding the submediant helps musicians create more complex and interesting harmonic progressions.
