Chords in Major Key
Definition of a Major Key
In music theory, a major key is a musical scale that is based on a major scale. The major scale is a specific pattern of whole and half steps that creates a distinct sound and tonality. The major key is characterized by its bright and uplifting sound, often associated with feelings of joy and happiness.
Triads in a Major Key
In a major key, triads are built from the notes of the major scale. A triad is a chord consisting of three notes: the root, the third, and the fifth. The root is the starting note of the chord, the third is the note two steps above the root, and the fifth is the note four steps above the root. In a major key, the triads built from each note of the major scale follow a specific pattern: major, minor, minor, major, major, minor, diminished.
Seventh Chords in a Major Key
Seventh chords are four-note chords that consist of the root, third, fifth, and seventh of a scale. In a major key, the seventh chords are built by adding the seventh note of the major scale to each triad. The resulting chords are named based on their quality: major seventh, minor seventh, minor seventh, major seventh, dominant seventh, minor seventh, and half-diminished seventh.
Chords in Minor Key
Definition of a Minor Key
A minor key is a musical scale that is based on the natural minor scale. The natural minor scale is a variation of the major scale, with a different pattern of whole and half steps. The minor key is known for its darker and more melancholic sound, often evoking feelings of sadness or introspection.
Triads in a Minor Key
In a minor key, triads are built using the notes of the natural minor scale. Similar to the major key, triads in a minor key follow a specific pattern: minor, diminished, major, minor, minor, major, major.
Seventh Chords in a Minor Key
Seventh chords in a minor key are constructed by adding the seventh note of the natural minor scale to each triad. The resulting chords are named based on their quality: minor seventh, half-diminished seventh, major seventh, minor seventh, dominant seventh, major seventh, and minor seventh flat five.
Relationship between Major and Minor Keys
Relative keys are pairs of major and minor keys that share the same key signature. The major key and its relative minor key are considered closely related because they use the same set of notes, but have a different tonal center. For example, the relative minor of C major is A minor. This relationship allows for smooth transition and modulation between major and minor tonalities.
Parallel keys are pairs of major and minor keys that share the same tonic note. In a parallel key relationship, both the major and minor keys start on the same note, but have different key signatures. For example, the parallel minor of C major is C minor. Parallel keys can be used to create contrasting moods within a musical composition.
Common Chord Progressions in Major Key
The I-IV-V progression is one of the most commonly used chord progressions in major keys. This progression refers to the chords built on the first, fourth, and fifth scale degrees of the major key. For example, in the key of C major, the I-IV-V progression would consist of the chords C, F, and G. This progression creates a strong sense of resolution and is often used in many popular songs.
The ii-V-I progression is another popular chord progression in major keys. This progression refers to the chords built on the second, fifth, and first scale degrees of the major key. For example, in the key of C major, the ii-V-I progression would consist of the chords Dm, G, and C. The ii-V-I progression is commonly used in jazz and provides a smooth and harmonically rich sound.
The I-V-vi-IV progression is a widely recognized chord progression in major keys, often referred to as the “Four Chords” progression. This progression refers to the chords built on the first, fifth, sixth, and fourth scale degrees of the major key. For example, in the key of C major, the I-V-vi-IV progression would consist of the chords C, G, Am, and F. This progression has been used in countless hit songs across different genres and is known for its catchy and ear-pleasing qualities.

Common Chord Progressions in Minor Key
The i-iv-V progression is a commonly used chord progression in minor keys. This progression refers to the chords built on the first, fourth, and fifth scale degrees of the minor key. For example, in the key of A minor, the i-iv-V progression would consist of the chords Am, Dm, and E. This progression has a melancholic and introspective sound commonly heard in various styles of music.
The i-VI-III-VII progression is another chord progression frequently used in minor keys. This progression refers to the chords built on the first, sixth, third, and seventh scale degrees of the minor key. For example, in the key of D minor, the i-VI-III-VII progression would consist of the chords Dm, Bb, F, and C. This progression creates a sense of tension and release, often used to evoke emotional depth and complexity in music.
The i-III-VII-VI progression, also known as the “Andalusian cadence,” is a distinctive chord progression commonly found in flamenco and Spanish music. This progression refers to the chords built on the first, third, seventh, and sixth scale degrees of the minor key. For example, in the key of E minor, the i-III-VII-VI progression would consist of the chords Em, G, D, and C. This progression creates a passionate and dramatic atmosphere, capturing the essence of traditional Spanish music.
Extensions and Alterations
Extended chords are chords that go beyond the basic triad or seventh chord by adding additional tones. Common extended chords include the ninth, eleventh, and thirteenth chords. These chords add color and complexity to the harmonic progression, providing a wider range of tonal possibilities.
Altered chords are chords that have one or more of their tones modified by raising or lowering them by a half step. Altered chords can create tension and dissonance, which can then be resolved to more stable chords. Commonly altered chords include the dominant chords with raised or lowered fifths or ninths.

Major Key Substitutions
Chord substitution is the technique of replacing a chord with another chord that shares similar harmonic function. In major keys, common chord substitutions include replacing the IV chord with the ii chord, or replacing the V chord with the bVII chord. These substitutions can add variety and create interesting harmonic progressions in a composition.
Minor Key Substitutions
In minor keys, chord substitutions can also be utilized to create new harmonic possibilities. Common substitutions include replacing the i chord with the VI chord, or replacing the V chord with the bIII chord. These substitutions can add color and variation to a minor key progression, allowing for unique and unexpected harmonic movements.
Borrowed Chords from Parallel Modes
Modal interchange refers to the borrowing of chords from parallel modes to create harmonic interest and variety within a composition. In major keys, borrowed chords can include chords from the parallel natural minor, harmonic minor, or melodic minor scales. In minor keys, borrowed chords can include chords from the parallel major scale or other related modes.
Modal Interchange in Major Key
Modal interchange in a major key often involves borrowing chords from a parallel minor key or other related modes. This technique can introduce chords with a different tonality, adding tension and color to the progressions. Modal interchange can create harmonic surprises and evoke different emotional responses within a major key composition.
Modal Interchange in Minor Key
Modal interchange in a minor key can involve borrowing chords from a parallel major key or other related modes. By introducing chords with a different tonality, this technique can alter the mood and feel of the minor key progression. Modal interchange in a minor key can result in unique harmonies and tonal variations, enhancing the depth and complexity of the composition.
Chord inversions involve rearranging the notes within a chord to create a different voicing. Inversions of triads are achieved by moving the lowest note of the chord to the top, creating a different root position. Triad inversions can provide smoother voice leading, as well as add a sense of movement and variety to the harmonies.
Seventh Chord Inversions
Similar to triads, seventh chords can also be inverted to create different voicings. Inversions of seventh chords involve rearranging the notes within the chord, typically by moving the lowest note to the top. Seventh chord inversions can create more interesting and complex chord progressions, allowing for smoother voice leading and heightened harmonic interest.
Smooth Voice Leading
Voice leading refers to the smooth and logical movement of individual voices within a chord progression. This technique ensures a coherent and melodic flow, avoiding abrupt or awkward leaps in the musical line. In chord progressions, smooth voice leading can be achieved by minimizing the distance between chord tones and carefully selecting the most effective voicings.
Common Tensions in Chords
Tensions are additional notes added to a chord that extend beyond the basic triad or seventh chord. Common tensions include the ninth, eleventh, and thirteenth. These tensions can introduce color and dissonance to the harmony, adding complexity and depth. Careful attention to the resolution and voice leading of tensions is crucial for achieving a balanced and pleasing sound.
In conclusion, understanding the chords in major and minor keys is essential for musicians and composers. The triads and seventh chords in major and minor keys provide the building blocks for creating harmonically rich and expressive music. Additionally, exploring chord progressions, substitutions, extensions, and inversions expands the creative possibilities and enhances the musical experience. Whether it’s a major key with its bright and uplifting sound or a minor key with its melancholic and introspective nature, mastering chord theory opens up a world of musical exploration and expression.
