Chords and harmony — Music, 11–13 years
How notes sounding together support, colour and sometimes unsettle a melody. Music, 11–13 years.
Harmony is sound in layers
Harmony happens when different notes sound at the same time and relate to one another. A chord is a group of notes heard together; a song can move from one chord to another beneath its melody. Harmony may feel calm, bright, dark or tense.
Why chords help a melody
A melody on its own tells a line, but chords can show where that line is heading and how a phrase should feel. Musicians developed harmony to make music fuller and to create movement between tension and rest. The same melody can sound different when its supporting chords change.
Building a C major chord
Start with the C major scale: C, D, E, F, G, A, B. Choose C, then skip one scale note to E, and skip one more to G; C–E–G is a three-note chord called C major. Play them together, and the notes support one another rather than forming a melody in sequence.
Harmony is not simply many notes
It is tempting to think that adding more notes always creates better harmony. That makes sense because a full sound can seem richer, but notes can clash or hide the melody when their relationships are ignored. Harmony depends on which notes sound together and how they move, not on quantity alone.
Harmony in songs and screens
A guitarist or keyboard player often uses chords to accompany a singer. Film composers change the harmony to make a scene feel safe, mysterious or unsettled, even before anything happens. This effect is real, but a chord does not force everyone to feel exactly the same emotion.
