Harmony and Counterpoint
How simultaneous and successive pitches combine into chords, progressions, and independent melodic lines.
Definition
The study of how pitches combine vertically into chords and progressions (harmony) and how independent melodic lines are woven together (counterpoint) within the tonal system.
Scope
Covers the two complementary dimensions of Western polyphony: harmony, the vertical study of chords and their functional progression within a key, and counterpoint, the horizontal study of combining independent melodic voices. Includes voice leading, figured bass, functional tonality, species counterpoint, chromaticism, and modulation. Excludes large-scale formal organization, treated under form and analysis.
Sub-topics
Core questions
- How are chords built, labeled, and connected into functional progressions?
- What rules govern smooth voice leading between chords?
- How does counterpoint combine independent melodic lines?
- What is the difference between a harmonic and a contrapuntal conception of music?
- How do chromaticism and modulation extend the diatonic system?
Key concepts

- Modulation
Key theories
- Theory of the fundamental bass
- Rameau argued that chords are generated from a root and that harmonic motion is driven by the succession of these roots (the fundamental bass), establishing the modern notion of chord identity and inversion that underpins functional harmony.
History
Renaissance counterpoint, codified pedagogically by Fux's Gradus ad Parnassum, gave way in the eighteenth century to Rameau's harmonic theory of the fundamental bass; the two perspectives — line and chord — have coexisted in tonal pedagogy ever since.
Debates
- Harmony versus counterpoint as the primary explanation of tonal music
- Rameau's chord-rooted harmonic theory and the older contrapuntal tradition offer rival accounts of what fundamentally generates tonal music — vertical chord succession or the combination of independent lines — a tension that later theory has sought to reconcile.

Frequently asked questions
- What is the difference between harmony and counterpoint?
- Harmony studies the vertical stacking of pitches into chords and their progression; counterpoint studies the horizontal combination of independent melodic lines. The same passage can be heard both ways.
- Are the rules of voice leading arbitrary?
- They codify what experienced listeners hear as smooth and idiomatic in common-practice tonality; they describe a style rather than a universal law, and other idioms follow different conventions.
