The answer it the thesis. It explains what the entire essay will be about in one sentence.
We judge the quality of music works and performances by averting our attention to the sounds instruments make. The dramatic facial expressions actors/actresses portray on their face. The technique musicians use while playing their instrument. The way the costumes are designed in a performance. If the guest speaker in a performance stuttered or forgot a pat of their speech. If a composer’s sheet music dropped in the middle of composing a recital/performance/play. To sum it up, we pay attention to the little details in the things we see/witness, which makes us quick to judge.
Hope that helps!
