Answer:
Rubato
Explanation:
Rubato–flexible hurrying or slowing of tempo to add emotion–was favored over strict tempo, and composers would even mark this into their scores.
Now, instead of following a set tempo through an entire movement of a piece, the tempo changed throughout the movement. And, not surprisingly, composers even began to add emotion words to their tempo markings. For example, a strict allegro might be replaced with allegro agitato, that is, brisk and agitated.
