Music has the remarkable ability to evoke emotions and heighten the tension in visual storytelling. In film scores, composers often use specific harmonic techniques to build suspense and keep audiences on the edge of their seats. One of the most effective tools in this arsenal is the suspended chord, or “sus chord,” which creates a sense of anticipation and unresolved tension.
Understanding Suspended Chords
Suspended chords are chords that replace the third with either a second or a fourth. This substitution creates a sound that feels unresolved or waiting to be completed. The two main types are:
- Sus2 chords: Replace the third with the second scale degree.
- Sus4 chords: Replace the third with the fourth scale degree.
These chords do not have a defined major or minor quality, which makes them perfect for creating suspense. They naturally lead the listener to anticipate a resolution, making them ideal for suspenseful music.
Using Suspended Chords in Film Scores
Composers strategically incorporate suspended chords into their progressions to generate tension. By delaying the resolution to a consonant chord, they keep the audience in a state of anticipation. This technique is especially effective during moments of uncertainty or danger.
Common Progressions for Suspense
Some typical progressions include:
- Sus2 → Major or minor chord
- Sus4 → Dominant seventh chord
- Sus4 → Sus2 → Resolution to a major or minor chord
- Extended suspensions over a sustained bass note
These progressions create a feeling of instability that is only resolved when the harmony finally settles, often during a key moment in the film.
Building Suspense with Progression Techniques
Beyond simple suspensions, composers use various techniques to enhance suspense:
- Delayed resolutions: Holding on suspended chords longer than usual.
- Chromatic suspensions: Using non-diatonic suspensions to add unpredictability.
- Layering suspensions: Combining multiple suspensions for complex tension.
Dynamic shifts in volume, tempo, and instrumentation further amplify the suspense created by harmonic choices.
Examples in Film Music
Many iconic film scores utilize suspended chords to evoke suspense. For instance:
- Hans Zimmer’s “Inception”: Uses suspensions to build tension during key moments.
- John Williams’ “Jaws”: Employs unresolved harmonies to create anticipation.
- Howard Shore’s “The Lord of the Rings”: Uses suspensions in the orchestration to heighten emotional stakes.
These examples demonstrate how harmonic suspense is a vital element in storytelling through music.
Conclusion
Suspended chords and their strategic use in progressions are powerful tools for building suspense in film scores. By creating harmonic tension and delaying resolution, composers can manipulate emotional responses and enhance storytelling. Understanding these techniques enriches both the appreciation of film music and the craft of composition.
