Key Differences
Harmony in music refers to the simultaneous combination of notes in a way that produces a pleasing auditory experience, involving chords and the relationship between them. It adds depth and complexity to music. Unison, on the other hand, occurs when two or more voices or instruments produce the same pitch or note at the same time, creating a single, unified sound without tonal variation.
Harmony requires an understanding of musical theory, including scales, chords, and intervals, to create a rich, layered sound that enhances the melody. Unison, while simpler, demands precise timing and pitch control from all participants to achieve a coherent and powerful collective sound.
In a choral or orchestral setting, harmony is achieved by different sections (like sopranos, altos, tenors, and basses in a choir) singing different parts that complement each other, while unison might be used for specific dramatic effects or to emphasize a particular melody or theme within a piece.
Harmony can evoke various emotions and moods within a piece of music, depending on the types of chords and intervals used, such as happiness, sadness, tension, or resolution. Unison, due to its singular pitch, relies more on dynamics, rhythm, and articulation to convey emotion and intensity.
While harmony enriches a piece of music with complexity and texture, unison brings a sense of unity and focus, often used to highlight a particular section of music or to bring all performers back to a common point before diverging into harmonious complexity again.
