Harmony: notes sounding together — Music, 7–10 years
Harmony happens when different notes sound at the same time and support a melody. The combination can feel settled, bright, tense or ready to move.
What is harmony?
Harmony is what we hear when different notes sound together, often underneath a melody. Some combinations feel settled, while others feel bright, tense or as if they want to move somewhere else. A chord is a small group of notes played or sung together as one musical colour.
Why add notes together?
A melody alone can be clear, but harmony can support it, make it richer and guide where it feels like going. Singers and instrument players began making music together and discovered that some note combinations blended well while others created useful tension. Harmony gives a melody a musical setting.
Build a simple chord
Start with the note C. Count up the white keys, including C: C is 1, D is 2, E is 3, F is 4, G is 5. Choose C, E and G: they are the first, third and fifth notes of the C major scale. Play them together, then sing C above them to hear melody resting on harmony.
The one-note trap
A common mistake is to think harmony is simply any note played after the melody. That is reasonable because we often notice accompaniment changing beneath a tune. Harmony means notes sounding at the same time, not merely one after another. Notes played in turn form a melody or sequence unless their overlap creates harmony.
Harmony in real life
You hear harmony when a singer is joined by a guitarist, when several friends sing different notes or when a film’s music makes a scene feel hopeful or dangerous. Chords also fill out songs in headphones, adverts and games. If you sing a different note that fits with a friend’s note, you are making harmony together.
