Step-by-step explanation:
Yes, expressive effects can be achieved by changes in the dynamic level of musical sounds.True Dynamics in music refer to the volume or loudness of a sound. By altering the dynamic level, musicians can create a wide range of emotions and moods in their compositions. For example, a crescendo, which is a gradual increase in volume, can build tension and excitement, while a decrescendo, which is a gradual decrease in volume, can create a sense of calm or peacefulness.
