What is the relationship between the tonic, supertonic, mediant, subdominant, dominant, and submediant in a major scale?

In a major scale, the tonic is the first note and serves as the main key center. The supertonic is the second note, the mediant is the third note, the subdominant is the fourth note, the dominant is the fifth note, and the submediant is the sixth note. These notes create a specific pattern of intervals that give the major scale its characteristic sound.
