What role does harmony play in a composition?

    We define harmony as the sound part of the music, which produces the simultaneous notes, chords and all the more musical structure. Combined with rhythm and melody, harmony is one of the three fundamental elements of music formation.

    In music, the best meaning for harmony would be the terms balance and order.

    Because the chords that produce this harmony must first be in balance (a combination of pleasing sounds to the ear).

    And second, they need to be in order with some scale and harmonic field, within a pattern or rule, for the harmony produced to make sense.

    Harmony is like an overlap of notes that support the melody.

    Every part of chords in music is within harmony. We can say that harmony sustains melody, gives balance.

    A person doing an acoustic show voice and guitar, harmonizes with the chords on the guitar and the melody (sung notes) with the voice.
