In this detailed exploration, we will delve into the intricacies of classical harmony, offering Classical Harmony Composition Tips and discussing Advanced Classical Harmony Techniques. For those seeking to deepen their knowledge, an Online Course on Classical Harmony can be a transformative experience.

The Essence of Classical Harmony

Classical Harmony Insights

At its core, classical harmony is about the interplay of chords and the rules that govern their progression. It involves the vertical stacking of pitches, typically in triads, and their horizontal movement, which creates the harmonic flow of a piece. This interplay generates the tension and release that characterizes much of classical music.

The fundamental unit of classical harmony is the triad, a three-note chord consisting of a root, third, and fifth. These triads can be major, minor, diminished, or augmented, each imparting a unique quality to the music. Understanding Classical Harmony requires a solid grasp of these basic building blocks and how they interact within a key.

Historical Context

Classical Harmony Insights

The development of classical harmony can be traced back to the early Baroque period, evolving significantly through the Classical and Romantic eras. Composers such as Johann Sebastian Bach, Wolfgang Amadeus Mozart, and Ludwig van Beethoven were pivotal in shaping the harmonic language that defines classical music.

Bach’s use of counterpoint and harmonic innovation laid the groundwork for future composers. His well-tempered tuning system allowed for greater harmonic flexibility, enabling the exploration of distant key areas. Mozart, on the other hand, refined harmonic practice with his elegant and balanced compositions, while Beethoven expanded harmonic boundaries, infusing his music with dramatic contrasts and emotional depth.

Fundamental Concepts

Classical Harmony Insights

Diatonic Harmony

Diatonic harmony involves chords built from the notes of a single key. The seven diatonic chords in a major or minor key each have specific functions, such as tonic, dominant, and subdominant. The tonic chord (I) serves as the home base, the dominant chord (V) creates tension that resolves back to the tonic, and the subdominant chord (IV) provides a preparatory function.

Chromatic Harmony

As composers sought greater expressiveness, they began to employ chromatic harmony, incorporating notes outside the key. This practice adds color and complexity, creating richer harmonic textures. Chromaticism became particularly prominent in the Romantic period, exemplified by the works of composers like Richard Wagner and Franz Liszt.


Modulation, or changing keys within a piece, is a powerful tool in classical harmony. It can create contrast, highlight structural divisions, and enhance emotional impact. Common modulations include moving to the dominant or relative minor, though more adventurous composers might explore distant key relationships.

Classical Harmony Composition Tips

  1. Start with Strong Root Movement: The root movement of your chords should create a sense of direction. Common root movements include descending fifths or ascending seconds. These movements help establish a clear harmonic progression.
  2. Voice Leading: Smooth voice leading ensures that individual melodic lines within the harmony move in a coherent and pleasing manner. Avoid large leaps and aim for stepwise motion whenever possible.
  3. Use of Inversions: Chord inversions can add variety and interest to your progressions. By changing the bass note, you can create smoother transitions and avoid monotony.
  4. Non-Chord Tones: Incorporating non-chord tones like passing tones, neighbor tones, and suspensions can add melodic interest and tension to your harmony.
  5. Balance Diatonic and Chromatic Harmony: While diatonic harmony provides stability, chromatic harmony can add excitement and surprise. Use chromatic chords judiciously to enhance your harmonic palette without overwhelming the listener.

Advanced Classical Harmony Techniques

Secondary Dominants

Secondary dominants are chords that temporarily tonicize a chord other than the tonic. For example, in the key of C major, the chord G7 (V7) naturally resolves to C (I). A secondary dominant like D7 (V7/V) resolves to G (V), creating a temporary modulation. This technique adds harmonic interest and complexity.

Neapolitan Chords

The Neapolitan chord, typically a major chord built on the lowered second scale degree, adds a dramatic and unexpected twist. In C minor, for example, the Neapolitan chord would be D♭ major. This chord often appears in first inversion and resolves to the dominant, creating a strong sense of tension and release.

Augmented Sixth Chords

Augmented sixth chords, found primarily in the Classical and Romantic periods, include the Italian, French, and German augmented sixth chords. These chords typically resolve to the dominant and are characterized by the interval of an augmented sixth between two of their notes. For example, in A minor, the German augmented sixth chord (A♭, C, E♭, F♯) resolves to the dominant chord (E).

Extended Tertian Harmony

Extended tertian harmony involves chords that extend beyond the traditional triad by adding additional thirds. These include seventh, ninth, eleventh, and thirteenth chords. While these chords are more common in jazz, they appear in late Romantic and early 20th-century classical music as well. They add lushness and complexity to the harmonic texture.

Practical Application and Analysis

Analyzing Beethoven’s Harmonic Language

Beethoven’s Symphony No. 5 in C minor provides a rich field for harmonic analysis. The opening motif is built on the tonic and dominant chords, creating immediate tension. As the symphony progresses, Beethoven employs chromaticism, modulation, and dramatic dynamic shifts to maintain interest and drive the narrative forward.

The second movement, in contrast, offers a lyrical theme supported by more stable harmonies. Beethoven’s use of secondary dominants and chromatic passing tones enriches the harmonic landscape, demonstrating his mastery of both diatonic and chromatic harmony.

Composing a Short Piece

When composing a piece, start with a simple harmonic progression, such as I-IV-V-I. Experiment with inversions and non-chord tones to add variety. Introduce secondary dominants to create moments of heightened tension. If appropriate, use a Neapolitan chord or an augmented sixth chord to surprise the listener.

Consider modulating to a new key for contrast. For example, a piece in C major might modulate to G major (the dominant) or A minor (the relative minor). Use smooth voice leading to transition between keys seamlessly.
