overharmonization

Overharmonization is a term used in music theory to describe the practice of adding an excessive number of chords or harmonic complexities to a musical passage. It can refer to the use of too many dissonant chords, overly chromatic progressions, or a rapid succession of chords that obscure the underlying harmonic structure. While some degree of harmonic richness can enhance a piece, overharmonization can lead to a cluttered and confusing sound, making it difficult for the listener to follow the melody or discern the intended harmonic movement.

The perception of overharmonization is subjective and can depend on the musical style, historical context, and the listener's familiarity with certain harmonic practices. For instance, what might be considered overharmonized in classical music might be standard in contemporary jazz or certain avant-garde genres. Composers might intentionally employ overharmonization to create specific effects, such as tension, disorientation, or a sense of overwhelming complexity. However, when used unintentionally or excessively, it can detract from the clarity and impact of the music.

In popular music, overharmonization might manifest as the use of numerous seventh, ninth, or altered chords in a simple song structure, or the frequent modulation through distant keys. While interesting harmonic language is often a hallmark of sophisticated songwriting, a balance is typically sought between harmonic interest and accessibility. The goal is often to support the melody and enhance the emotional content of the music without overwhelming it.
