Suspension and Resolution Identification by Ear

Core Idea

Suspensions are non-harmonic tones prepared in one chord and resolved downward in the next, creating characteristic dissonance followed by consonance. The tension and release of a suspension is immediately audible; recognizing these patterns helps distinguish melodic embellishment from harmonic function. Common suspension types (4-3, 7-6, 2-3) have distinct sonic profiles and structural roles.

Explainer

From your work with non-harmonic tones, you know that suspensions follow a three-step pattern: preparation (the suspended note appears as a consonance in the previous chord), suspension (the note is held while the harmony changes, creating dissonance), and resolution (the note moves down by step to a consonant note in the new chord). What you are now developing is the ability to *hear* this pattern in real music and identify which type of suspension it is — by the specific interval the suspended note makes against the bass.

The 4-3 suspension is the most common. A voice holds the fourth above the bass while the chord changes to a dominant, then resolves down to the third. What you hear is a momentary "stuck" quality on the chord that should be V — the harmony has arrived at the dominant, but one voice is still holding on to the previous note, refusing to settle. When it finally resolves down a half or whole step to the third of the dominant, the chord "clicks into place." This is the characteristic sound of Renaissance polyphony and Baroque counterpoint — a kind of aching delay before the harmony completes itself.

The 7-6 suspension has a smoother, more flowing quality because both the suspended seventh and its resolution are relatively close to the bass. You hear a slight tension that releases stepwise; it tends to appear in inner voices and often decorates progressions in flowing eighth-note textures. The 2-3 (bass suspension) is the inverse: the bass voice is the one that is suspended, holding from the previous chord while the upper voices change harmony above it. This creates a distinctive "ground" beneath the new chord — the bass hasn't caught up yet — and resolves when the bass finally moves down by step to the root of the new chord.

The key to identifying suspensions by ear is listening for the three-phase shape rather than trying to label intervals immediately. You will hear a smooth arrival into the chord, then a slight catch or clash — the dissonant moment where the suspended note doesn't quite fit — followed by a relaxation as it resolves downward. Suspensions never resolve upward (that would be an anticipation or appoggiatura). Once you hear that characteristic catch-and-release shape, you can then determine the type by asking: where is the suspended note relative to the bass? If it is a fourth above (wanting to become a third), it is a 4-3. If it is a seventh above (wanting to become a sixth), it is a 7-6. This is what distinguishes the analytical ear from the descriptive one: not just hearing the tension, but identifying its precise location within the voice-leading fabric.
