Process:

I first used Logic to mark my video by changes in mood or other events that I wanted to synchronize, like Agent Peggy crossing out her note, and punching the bad guy, to mark the start of the climax. 

I used logic loops in order to find sound effects that would fit. I used the telephone ringing at the beginning, the car driving past, and the body crashing through sound as my main sound effects. All of these were logic loops that I cut to use the relevant portions and faded in order to integrate them in the main sound. During the buildup section after the car drives past, I used part of an answering machine tape loop to capture the grainy sound. This was intended to mimic a record player playing music as Peggy walked towards the warehouse. My buildup music is intended to mimic Benny Goodman and other big band songs from the 1940's-1950's, when this story takes place. In order to do this I included a drum layer that includes a lot of loud, low drum sounds, and sharp brass instruments. When Peggy punches the first guy, there is a loud, high-pitched trumpet chord, which mimics sound effects of traditional superhero films. Adding this loud chord progressed the music into its climax. The piece abruptly ends with the sound effect of the main smashing through the window. Without closure, the viewer is intrigued and will want to watch the full show. I also used the pencil tool to create a volume change when the camera changes view from outside, where Peggy is, to inside, where the unobservant guard is. I made the sound lower to represent being inside and not being able to hear the sound as well. The sound abruptly increases volume when the camera angle is outside again.

In the beginning of the video I used a low bass in order to create tension, the notes increasingly get closer together until the end, where they are synchronized with Peggy's eyes moving and her crossing out her note. The low sounds create an introduction that matches the video, low and dark, with tension because of the emergency phone call. The notes getting slightly closer together is supposed to create intrigue and interest, as the tension is increasing.

I integrated feedback my acknowledging that having a break in sound when the note is crossed out would create a gap that would be hard to reconcile, and so I added sound to that section, though it is synchronized, but keeps with the progression of the previous section of music. Because I had such a positive reaction to wanted to use period music, I decided to listen to more in order to get more inspiration for my own piece. I decided that "Sing, Sing, Sing" by Benny Goodman had the drumbeat and brass that I wanted to mimic, as well as the buildup from drums to drums and brass with an increasingly complex brass line.
