How do opera actors create literary works?

In this case, the method is as follows:

In terms of performance skills, opera singers need to have solid vocal skills and stage performance ability. They need to master the correct vocal methods and breathing skills through systematic vocal training to ensure the stability and beauty of pitch and timbre. They need to learn how to use body language and facial expressions to convey their emotions and inner world through stage performance training.

In terms of artistic accomplishment, opera singers need to have extensive cultural accomplishment and profound emotional experience. They need to be familiar with music works of different periods and styles, and understand the composer's creative background and intention in order to better understand and interpret music works. At the same time, they also need to understand the background and plot of the script through reading and learning, and deeply understand the character and destiny of the role.
