Answer:
Feeling and expressing emotion, and showing the audience amazing dynamics.
Step-by-step explanation:
By feeling and expressing your emotion, it shows the audience what the composer was feeling during the period of his life in which he wrote the piece. A simple thing like swaying back and forth with the rhythm can make a big difference.
Showing amazing dynamics to the audience makes them feel more involved with the music. It would be like if you just talked in a monotone all day. Everyone would get bored of it and want you to express some feelings in your talking. When you really focus on dynamics like contrasts between forte and piano, or accents on certain notes will catch the audience's attention and guarantee you a better performance.
Hope this helped! Have an amazing day!
