What is Harmonization?

Harmonization is the process of adding chords or additional notes to support a melody. The goal is to create harmony that complements the main melody and enhances the overall sound of the music. By selecting chords that match the notes of the melody, musicians can build a fuller and more expressive musical texture.

For example, if a melody is written in the key of C major, a musician might harmonize it using chords such as C major, F major, and G major. These chords help support the melody while reinforcing the key of the piece. Harmonization can also involve adding multiple vocal or instrumental parts that move alongside the melody.

Harmonization is widely used in songwriting, arranging, and composition across many musical styles. It plays an important role in choral music, jazz, pop, and orchestral arrangements. By carefully choosing how notes and chords support a melody, musicians can shape the mood, depth, and emotional impact of a piece of music.
