Chords In A Minor Scale

Understanding and Mastering Chords in a Minor Scale

The minor scale, with its characteristic melancholic and introspective sound, is a cornerstone of music theory and composition. Understanding its constituent chords is key to unlocking a vast world of musical possibilities, from crafting haunting melodies to building complex harmonic progressions. This comprehensive guide will delve into the intricacies of chords within a minor scale, exploring their functions, relationships, and practical applications. We'll move beyond simply listing the chords to truly understanding their roles within a musical context, empowering you to write and improvise with confidence.

Introduction: The Landscape of the Minor Scale

Before we dive into the chords themselves, it's crucial to establish a firm understanding of the minor scale itself. There are three main types of minor scales: natural minor, harmonic minor, and melodic minor. Each has its unique characteristics and corresponding chord progressions. The choice of minor scale significantly impacts the overall mood and harmonic direction of your music.

• Natural Minor: This is the most basic form, built using a pattern of whole (W) and half (H) steps: W-H-W-W-H-W-W. It's characterized by a slightly unsettling, "incomplete" feeling due to the absence of a leading tone (the 7th degree).

• Harmonic Minor: This scale modifies the natural minor by raising the 7th degree by a half step. This creates a strong leading tone, pulling naturally towards the tonic (the 1st degree). This creates a richer, more dramatic harmonic potential.

• Melodic Minor: This scale modifies both the 6th and 7th degrees of the natural minor when ascending. The 6th is raised by a half step, creating a major 6th interval, and the 7th is also raised, creating a leading tone. The descending form often reverts to the natural minor scale. This creates a more lyrical and flowing quality.

The Chords of the Natural Minor Scale

Let's begin with the natural minor scale, its chords providing a foundation for understanding the others. Each degree of the natural minor scale can be used to build a chord, resulting in seven chords:

1. i - Minor Chord: This is the tonic chord, built from the root (1st degree) – a minor triad. It represents the home base, the center of gravity for the scale. Think of it as the emotional core of the piece.

2. ii - Minor Chord: Built on the 2nd degree, this is also a minor triad. It often functions as a subdominant chord, creating a sense of movement towards the tonic.

3. iii - Major Chord: This is the mediant chord, a major triad built on the 3rd degree. It adds a touch of brightness and contrast to the overall minor feel.

4. IV - Major Chord: This is the subdominant chord, a major triad built on the 4th degree. It creates a strong sense of anticipation leading back to the tonic.

5. v - Minor Chord: This is the dominant chord, a minor triad built on the 5th degree. In natural minor, it lacks the leading tone characteristic of the major scale's dominant.

6. vi - Major Chord: This is a major triad built on the 6th degree, often functioning as a relative major chord. It provides a brighter, contrasting section.

7. vii° - Diminished Chord: This is a diminished triad (a minor third stacked on a minor third) built on the 7th degree. It acts as a leading-tone chord in natural minor.

The Chords of the Harmonic Minor Scale

The harmonic minor scale introduces a significant change with its raised 7th degree. This alteration dramatically affects the chords built upon the scale degrees:

1. i - Minor Chord: Remains the same as in the natural minor scale.

2. ii - Minor Chord: Remains the same as in the natural minor scale.

3. iii - Major Chord: Remains the same as in the natural minor scale.

4. IV - Major Chord: Remains the same as in the natural minor scale.

5. v - Major Chord: This is the crucial difference. The raised 7th degree transforms the v chord from a minor to a major chord. This creates a strong pull towards the tonic, providing a much more defined sense of resolution.

6. vi - Major Chord: Remains the same as in the natural minor scale.

7. vii° - Major-Minor Chord: The raised 7th degree creates a major-minor seventh chord (also called a dominant seventh). This acts as a powerful leading tone chord, strongly emphasizing the resolution to the tonic.

The Chords of the Melodic Minor Scale

The melodic minor scale, with its unique ascending and descending forms, presents a more complex chord structure. We'll focus on the ascending form for the purposes of chord construction:

1. i - Minor Chord: This is the same as the natural and harmonic minor scales.

2. ii - Minor Chord: This is also the same as in the natural and harmonic minor scales.

3. iii - Major Chord: Remains the same as the other minor scales.

4. IV - Major Chord: This chord remains unchanged from the natural and harmonic minor scales.

5. v - Major Chord: This is the same as the harmonic minor scale’s V chord, creating a strong pull toward the tonic.

6. vi - Major Chord: The raised 6th degree transforms this chord into a major triad, adding brightness and complexity to the harmonic progression.

7. vii° - Major-Minor Chord: This again produces a major-minor seventh chord (dominant seventh) similar to the harmonic minor scale.

The descending form of the melodic minor scale often uses the chords of the natural minor scale.

Chord Functions and Progressions in Minor Keys

Understanding chord functions is vital for creating effective progressions. The following functions apply generally across all three types of minor scales, although the specific flavor will vary:

• Tonic (i): The home base, providing stability and resolution.

• Subdominant (IV): Creates tension and anticipation, often preceding the dominant.

• Dominant (V): Generates a strong pull towards the tonic, often creating a sense of climax. In harmonic and melodic minor, the major V chord is especially powerful in this role.

• Submediant (vi): Provides a contrasting, often brighter sound, adding color and variety to the progression.

Common progressions in minor keys include:

• i - IV - V - i: A classic progression that emphasizes the tonic and creates a satisfying resolution.

• ii - V - i: A more dramatic progression, relying on the subdominant's anticipation and the dominant's strong pull.

• vi - ii - V - i: A progression that incorporates the relative major (vi) for a brighter contrast.

• i - iii - vi - IV - V - i: A longer progression illustrating the use of multiple chords for a more complex feel.

Remember that these are merely suggestions – experimentation is key! Try different combinations, experiment with inversions, and add seventh chords for a richer sound.

Seventh Chords in Minor Scales

Adding seventh chords to minor key progressions increases the harmonic complexity and adds depth. The following illustrates the seventh chords for each degree in a natural minor scale:

1. i7 - Minor 7th: A minor chord with a minor 7th interval added.

2. ii7 - Minor 7th: A minor chord with a minor 7th interval added.

3. iii7 - Major 7th: A major chord with a major 7th interval added.

4. IV7 - Major 7th: A major chord with a major 7th interval added.

5. v7 - Minor 7th: A minor chord with a minor 7th interval added.

6. vi7 - Major 7th: A major chord with a major 7th interval added.

7. vii°7 - Half-Diminished 7th: A diminished chord with a minor 7th interval added.

These seventh chords can be used to create rich and sophisticated progressions, adding another layer to your harmonic vocabulary. The same principles apply to harmonic and melodic minor scales, however, remember the altered 7th degree will impact the seventh chords built on degrees V and VII.

Practical Applications and Compositional Techniques

Understanding the chords of minor scales is not merely theoretical knowledge; it’s a practical tool for musicians. Here are some practical applications:

• Improvisation: Knowing these chord progressions empowers you to improvise melodies and solos within a minor key. Target notes within the scale that best complement the chord changes.

• Songwriting: Minor scales and their chords form the foundation for countless songs across genres. Experiment with different chord progressions to find the right mood and feel for your song.

• Arranging: Arranging music for different instruments involves understanding how chords function within the harmonic structure. You can use this knowledge to create richer arrangements.

• Analysis: Analyzing existing music in minor keys allows you to understand the composer's choices and how they used the chords to create a specific effect.
