What are the similarity between tempo and dynamic?

Tempo and dynamics are both fundamental elements of music that contribute to its overall expression and feel. Tempo refers to the speed at which a piece of music is played, while dynamics pertains to the volume levels, indicating how loudly or softly music should be performed. Both aspects can dramatically influence the emotional impact of a piece, guiding the performer in conveying the intended mood. They often interact, as changes in tempo can affect perceived dynamics and vice versa, enhancing the musical narrative.
