Electronic music has revolutionized the way composers and producers approach harmony and melody. Among the various techniques used to create interest and tension are suspended and added tone chords. These chords add color and complexity to electronic compositions, making them more engaging for listeners.
Understanding Suspended Chords
Suspended chords, often abbreviated as “sus” chords, replace the third of a chord with either a second or a fourth. This creates a sense of suspension, waiting to be resolved either upward or downward. They are commonly used in electronic music to build tension or to create a floating, unresolved sound.
Types of Suspended Chords
- Sus2: Replaces the third with the second scale degree.
- Sus4: Replaces the third with the fourth scale degree.
For example, a Csus2 chord consists of the notes C, D, and G, while a Csus4 chord includes C, F, and G. These chords are often used as passing chords or to add a sense of openness.
Using Added Tone Chords
Added tone chords incorporate extra notes beyond the basic triad, such as the 6th, 7th, 9th, 11th, or 13th. These notes add richness and color to the harmony, making them popular in electronic music genres like trance, house, and ambient.
Common Added Tone Chords
- 6th chords: Add a sixth to the triad for a smooth, mellow sound.
- 9th chords: Include the ninth for a jazzy or soulful flavor.
- 11th and 13th chords: Provide complex, layered textures.
For example, a Cadd9 chord includes C, E, G, and D, creating a bright, open sound. These chords are often used in progressions to evoke emotion and maintain listener interest.
Practical Applications in Electronic Music
Suspended and added tone chords are versatile tools for electronic musicians. They can be used to build tension during a build-up, create lush soundscapes, or add subtle color to a track. Producers often experiment with these chords using synthesizers and digital audio workstations (DAWs) to craft unique harmonic textures.
Creating Suspended Tension
By using sus4 chords followed by resolution to a major or minor chord, producers can generate a feeling of anticipation. For example, moving from a Csus4 to a C major chord creates a satisfying resolution that enhances the emotional impact of the music.
Adding Color with Extended Chords
Incorporating added tone chords such as 9th or 13th chords can enrich a track’s harmonic palette. These chords are often used in pads, leads, or background layers to add depth and complexity, making the sound more immersive.
Conclusion
Suspended and added tone chords are powerful tools in the electronic musician’s toolkit. They enable artists to craft dynamic, emotionally engaging compositions by manipulating tension, resolution, and harmonic color. Experimenting with these chords can lead to innovative sounds and unique musical expressions in electronic music production.
