solved They are intended principally to provide an opportunity for students

They are intended principally to provide an opportunity for students to post questions or comments about the lesson material. Your instructor will respond to any questions that are posted and may offer responses to comments, as well. 
Students are also invited to post about any topic related to film or music, as long as it is at least tangentially related to the lesson material.  This is an opportunity to have a “classroom conversation” about cinematic and musical topics of interest.
In this lesson we examine the Star Wars trilogy, focusing on the second of the three films, The Empire Strikes Back (1980). We will examine four of the principal themes, and the manner in which these themes are used to reinforce the film’s narrative.

Specifically, we will consider:
The Star Wars/Luke Skywalker theme
The Darth Vader theme
The Love theme of Princess Leia and Han Solo
The Force/Yoda theme
