Dynamic Contrast

Contrast needs a reference. Build the drop with orchestration first, then move faders.

Dynamic contrast depends on a reference. If everything is loud, loud stops being loud. The quiet has to exist first. Arrangement can build the drop with orchestration, and removing a layer usually sounds more natural than pushing a fader.

The problem

One level from start to finish erases the climax. Rely on volume automation alone and quiet passages turn muddy while loud ones crowd.

Texture or frequency band

In soft passages, reduce layers and high frequencies. In loud ones, widen the bass and add brass or drums. Adding and removing low end creates more size than overall level. Keep the melody's register intact, or the loud passage becomes weight without direction.

Approach

Draw a dynamic curve and mark three drops that must be heard. Realise them through orchestration first, deciding which layer leaves and which enters, then move faders. Leave one beat of silence before a sudden accent, and allow at least eight bars for a long crescendo, or it will sound like a sudden jump.

What to listen for

Hear the alternation of soft and strong in the first movement of Beethoven's Fifth. Hear how repetition accumulates in the long crescendo of the Seventh. Then hear the sudden accents and pauses in the second movement of Op. 110.

Common misunderstandings

Dynamics are not volume automation, and changing texture is often more effective. A dynamic mark is not an absolute value either, since it depends on context and the performance space.
