What Harmony Does

Summary

Harmony describes how notes sound when they occur together or in relation to one another. Rather than thinking of harmony as a set of rules or chord names, this guide focuses on what harmony does in music. Harmony supports melody, creates movement, and establishes a sense of tension and release. Understanding this function helps bass and guitar players make better musical decisions without relying on memorization.

What Harmony Is

Harmony occurs when multiple notes interact with one another. These notes may sound at the same time or move in sequence. Harmony gives music depth and context, allowing melodies to feel grounded, supported, or pulled in certain directions.

Harmony as Support

Harmony provides a foundation beneath melody. On bass, this often means outlining harmonic movement through roots and chord tones. On guitar, harmony may appear as chords, double stops, or implied voicings that support melodic content.

Harmony and Movement

Harmony creates motion through changes in stability and tension. Some harmonic sounds feel settled, while others create a pull toward resolution. This movement is what gives music forward momentum and emotional shape.

Application on Bass and Guitar

Understanding what harmony does allows bass players to choose notes that reinforce movement and stability. Guitar players can shape chord choices and voicings to highlight direction and color. In both cases, harmony becomes a functional tool rather than a theoretical abstraction.
