* Dynamics were not standardized. Composers would often specify dynamic markings in the score, but these markings were not always consistent. For example, the term "forte" might mean something different to one composer than it did to another.
* Dynamics were often used to create contrast. Baroque composers would often use sudden changes in dynamics to create dramatic effects. For example, a piece might start out softly and then suddenly get loud, or vice versa.
* Dynamics were also used to emphasize important moments in the music. For example, a composer might use a crescendo to build tension leading up to a climax.
Classical Period (1750-1820)
* Dynamics were standardized. By the Classical period, there was a general consensus on what the different dynamic markings meant. For example, "forte" now meant "loud," "piano" meant "soft," and so on.
* Dynamics were used more subtly. Classical composers used dynamics to create a sense of balance and flow in their music. They avoided sudden changes in dynamics and instead used gradual crescendos and decrescendos to create a sense of drama.
* Dynamics were also used to create a sense of unity. Classical composers would often use dynamics to bind together different sections of their music. For example, they might use a crescendo to connect the two halves of a sonata movement.
In general, the use of dynamics in the Baroque era was more spontaneous and unpredictable, while the use of dynamics in the Classical period was more controlled and refined.
