The first part is an original composition for orchestra.
The second part of this dissertation is an account of the career of the pop music producer, David Foster. Throughout his expansive career, David Foster has made significant contributions to the pop music canon, specifically within the "power ballad" form and within the genre of "classical crossover." Classical crossover music fuses important elements of popular music's form and sentimentality with serious concert music's romantic lyricism and orchestration. This new hybrid genre has proven remarkably successful within the music industry and the pivotal role of David Foster cannot be understated.
The dissertation is long but you can find the best parts by searching for "Jackie". I would then recommend starting on page 171 with the transcription of his in depth interview with Foster.
Part 2 starts on page 113. It covers Foster's entire career and has in depth analysis of several of his best known songs.
I found the account of writing "I Will Always Love You" for Whitney to be particularly interesting. The a cappella start was Kevin Costner's idea. The pause before and then the structure of the third verse resulted from Foster finishing a two verse version before he discovered a third verse existed. The final cut was a rough cut that
Foster played for Clive Davis who liked it so much he wouldn't let Foster touch it again. All in all it turned out pretty well.
Jackie's "To Believe" is also analyzed as another example of a Foster power ballad.
