Harmony refers to how notes are simultaneously sounded, creating a vertical element in the music. A single melody line or linear voice added to another line or voice is called a counterpoint. This combination of voices, each significant by itself, creates this “note against note.”

It is unique to music to be able to comprehend two things being “said” at the same time. While a composer may weave together two or three (or more) melodies (linear), he also recognizes what combining those melodies creates harmonically (vertical).
