The choice that best describes compositional devices providing dynamic contrast to a musical work is the use of crescendo and decrescendo. These techniques involve gradual changes in volume, where a crescendo indicates a build-up to a louder sound, and decrescendo denotes a decrease in volume. These dynamic changes create a sense of tension and release in music, contributing significantly to the emotional impact and overall expressiveness of a piece.

While the other options do contribute to the expression and interpretation of music, they do not inherently provide the same kind of sweeping dynamic contrast. Articulations primarily involve how notes are played—whether sharply, smoothly, etc.—rather than volume. Fermatas indicate a pause or hold on a note but do not affect the dynamic range across a piece. Similarly, rubato and ritardando focus on timing and tempo rather than altering volume dynamics. Therefore, the use of crescendo and decrescendo stands out as the clear choice for dynamic contrast.
