The Analysis needs to include all of these questions:
1. The number of different musical ideas in the piece (for example, can we say that there are two ideas A and B? Or is there only one?)
2. The timings (start and stop times) of the different sections of the piece. (Hint: Listen for changes in musical ideas and timbre, for example, points when different instruments come in or give way to others.)
3. Specific examples of how instruments are exemplifying unity and variety in those sections through the use of the following: (For example, the repeated rhythmic pattern played by the piano exemplifies unity.)
a) Dynamics: Where does the music get louder or softer? Is there any apparent reason for those changes?
b) Timbre: Where do instruments take over the melody or a solo passage?
c) Pitch: What is the general pitch level of the piece? Are there wide variations in pitch level?
4. Although there are sections that feature one instrument over others, whether you think this is a piece for a solo performer or for an ensemble.
5. A list of the characteristics of the musical style closest to the one this piece exemplifies.
6. Whether you think this piece serves (or could serve) a specific purpose.
7. Whether or not it has any specific connotation(s) for you.
