The dominant in a major, also known as the perfect fifth, is a fundamental interval in Western music. It is built on the fifth note of the major scale and is composed of a perfect fifth and a major third. The dominant chord, which is built on the dominant degree of the scale, is a major triad with a raised fifth. This chord creates a sense of tension and resolution, making it a common choice for endings and cadences.
Mastering the Dominant: A Comprehensive Guide
The dominant is a foundational chord in music, serving as the tonal center that a piece of music revolves around. Dominating a major scale is essential for guitarists, as it allows them to navigate chords, progressions, and solos effortlessly. Here’s an in-depth breakdown of the best structure for the dominant in a major key:
Intervallic Structure
The dominant chord is built on the fifth degree of the major scale. For example, in the key of C major, the dominant chord is G major. The intervallic structure of the dominant is:
- Root (1st): G
- Major third (3rd): B
- Perfect fifth (5th): D
Chords Within the Dominant
The dominant chord can be further broken down into three sub-chords:
- Root-position dominant (1st inversion): G-B-D
- First-position dominant (2nd inversion): B-D-G
- Second-position dominant (3rd inversion): D-G-B
Voicings and Inversions
The dominant chord can be voiced in various ways, including:
- Triad: G-B-D
- Seventh: G-B-D-F#
- Ninth: G-B-D-F#-A
- Eleventh: G-B-D-F#-A-C
Inversions are variations of the dominant chord where different notes are placed in the bass. The three inversions of the dominant are:
| Inversion | Root Position | First Position | Second Position |
|---|---|---|---|
| 1st | G (Root) | B (Third) | D (Fifth) |
| 2nd | B (Third) | D (Fifth) | G (Root) |
| 3rd | D (Fifth) | G (Root) | B (Third) |
Harmonic Context
The dominant chord typically resolves to the tonic chord (1st degree of the scale). In the key of C major, the dominant G major would resolve to C major. This resolution creates a sense of closure and stability.
Additionally, the dominant chord can be used in various harmonic progressions, such as:
- Dominant – Tonic: G major – C major
- Dominant – Subdominant: G major – F major
- Dominant – Relative minor: G major – E minor
Understanding the structure of the dominant chord is crucial for guitarists. By mastering its intervallic structure, chords, voicings, inversions, and harmonic context, you can unlock the power of this essential musical building block.
