Passing tones, suspensions, anticipations, escape tones, and other non-harmonic tones add melodic movement and harmonic interest. Their effectiveness depends on proper preparation, resolution, and rhythmic placement relative to strong beats.
Practice each non-harmonic tone type in strict voice-leading context: passing tones on weak beats between chord tones, suspensions prepared and resolved downward by step. Then use these techniques in free composition to add expressiveness.
You already know that non-chord tones are pitches that don't belong to the underlying chord but appear in the melody or inner voices. The deeper skill this topic develops is treating them not as accidents or violations but as deliberate compositional tools—each with its own "grammar" of preparation, statement, and resolution. Think of dissonance as a tension that earns its existence by being set up properly and then released satisfyingly.
The passing tone is the most intuitive: it fills in the stepwise space between two chord tones, moving in one direction on a weak beat. Its logic is purely linear—it creates momentum in the melodic line. The suspension is more powerful and more demanding. A suspension is prepared as a chord tone, held over (or "suspended") into the next chord where it becomes a dissonance, then resolved by step downward. The classic 4–3 and 7–6 suspensions in tonal music are some of the most expressive moments in the harmonic vocabulary precisely because the resolution arrives one beat late—the listener anticipates it, and the delay creates longing.
The anticipation works in the opposite direction: a note arrives on a weak beat *before* the chord that harmonizes it. Rather than hanging back, it rushes forward, creating a brief clash with the chord it's left. Escape tones are more ornamental: they leave a chord tone by step, then leap away in the opposite direction before resolving elsewhere. These feel more improvisatory, less structural than suspensions, and their effectiveness depends entirely on rhythmic placement and the surrounding voice-leading context.
The practical craft lies in rhythmic placement. Passing tones appear on weak beats so they slide through without disturbing harmonic stability; suspensions appear on *strong* beats so their dissonance lands with full weight. Getting this backwards—putting a suspension on a weak beat—robs it of its expressive force. Voice-leading principles you already know still govern everything: each voice should move smoothly, dissonances should resolve in the expected direction. Non-harmonic tones are not exceptions to voice leading—they are voice leading operating at the melodic surface level, adding expressive texture while the harmonic layer continues its functional work underneath.
