How would you briefly describe their musical characteristics?

After watching the instructional video of this week, please watch the first 30 minutes of Lo Sceicco Bianco and answer the following questions.
1) How many different music themes can you hear in the Main Titles (the very first minutes)? How would you briefly describe their musical characteristics?
2) What scenes/characters/situations do each of the mentioned music themes refer to during the first 30 minutes of the movie after the Main Titles?
3) Is there any music theme other than the ones exposed in the Main Titles? In which scene/situation?
Please notice: as you watch the movie, please consider the relationship between diegetic and non-diegetic music. Often, the sudden cuts and/or the ambiguity between the two, symbolizes the dichotomy between reality/illusion that I explain in the instructional video.
