Music, Image, Sound, and Screen

The coexistence of music and visual media became a common occurrence as video-sharing websites (i.e, Youtube) and streaming services (i.e, Netflix) came into being over the last decade or so. As a result, we tend to perceive the two elements altogether as a single entity and rarely question the nature of their compatibility – for instance, how is the process of collaboration between directors and composers? What are some of the translative techniques used to accurately compose a piece of music for a movie scene?

Ever since the revolutionary integration of synchronized sound into film in the early 1920s, films became an increasingly popular medium through which artists tell their stories. The collaborations between composers and film directors have led to the creation of countless unforgettable cinematic moments. Today, the phenomenal partnership between Christopher Nolan (director) and Hans Zimmer (composer) gave birth to several award winning films such as Inception (2017), Interstellar (2014), and Dunkirk (2017).

In an interview with IndieWire, Hans Zimmer confessed that the memorable theme of Interstellar was composed without referring to the plot of the movie: “Chris said to me, in his casual way. ‘So, Hans, if I wrote one page of something, didn’t tell you what it was about, just give you one page, would you give me one day of work?'” Having had Zimmer’s agreement, Nolan sent him a one-page typewritten letter of a short story: A father leaving his child to take on an important job. Zimmer then quickly wrote the main theme with a simple yet moving chord progression: VI – V – vi. Moreover, the melody consists of four intervals that decrease in size as the harmony develops, representing the expectation of the son and daughter toward their father’s return. Specifically, in the Years of Messages scene, the main theme creeps in while Cooper (the father) is reading years of unread messages from his son and daughter. Tom (the son) eventually gave up on sending the messages because Cooper never responded. As he explained to Cooper in his last message about his loss of faith toward Cooper’s promised return, the significance of the music became prominent: not only did it bring out the son and daughter’s feeling of disappointment toward his father by resolving into the minor chord at the end of each harmonic cycle, but it also served to highlight the stark contrast between the silence that surrounds Cooper in space and the grand music gesture that continued to build until the end of the scene. As a result, the music was able to represent the character’s emotions whenever it came on, heightening the emotional impact of the music as the story develops. As one analyst wrote: “[R]ather than simply being associated with a certain character or group of characters, Zimmer’s themes tend to emphasize the emotions a particular character or group is feeling at various points in the film”. Furthermore, the cyclic quality of the theme captivates the audience by its minimalistic approach, leaving room for the monologue and plot to sink in; as Zimmer himself put it: “Rather than doing a lot… I’m hypnotizing you.

Lastly, Zimmer’s music provides a level of spaciousness that is unparalleled in many other genres in music; it often fills up the frequency ranges with constant doublings of instrumental phrases and the use of synthesized sounds to provide a much fuller low end. As a result, his music sounds full and rich all on its own, yet the collaboration between the music and the film makes it that much more special – hence the power of film music to emote, inspire, and persuade.

‘Pro Tools’ as a Film Scoring Technology

One early afternoon, Amber settles down at the library and opens up her email tab; the top thread reads “Reminder: Film Music Draft due tomorrow”. She immediately opens up Pro Tools (audio production software) and delved into her scoring session. As a student film composer, she has been working with audio production softwares such as Logic Pro and Pro Tools for a few years now, producing brilliant music; yet many film composers have been utilizing the audio technology without fully understanding its history and all the endeavors that have gone into creating and continuously perfecting these audio production softwares. When did musicians and engineers conceive of this idea? How did this technology come into existence? Why was this important to the development of the film scoring industry? Moreover, how did this invention influence the way film composers create music today?

Interestingly, film music (soundtrack) as we know today was primarily performed live at movie theatres up until the 1930s– the advent of music synchronization to celluloid made it possible for film music to be a part of the viewing experience without the live accompaniment of the instrument ensemble. Since then, composers such as Max Steiner and Alfred Newman have been finessing the narrative power of music by creating impressive scores. This process, though, has made the director-composer collaboration a bit cumbersome: the director would either have face-to-face discussions and live experiments with the composer in front of a piano, or fully entrust the composer with the task of creating effective music for his or her film.

Thanks to UC Berkeley graduates Evan Brooks and Peter Gotcher, Pro Tools was first launched in 1991 as an audio editing software. Pro Tools was indeed very much limited by computers’ hard drive capacity at the time. Therefore, as computers became more and more powerful, the audio editing software gained true advantage given that its multi-track system allowed more and more tracks to be edited at the same time.

However, without proper input, Pro Tools would only serve as an editing software; i.e, composers would still have to book an orchestra to play their music, and then transfer the recording into Pro Tools for the sake of editing. As a result, the advent of MIDI (Musical Instrument Digital Interface) and virtual instruments allowed composers to experiment with numerous options of sound textures and effects in real time by connecting the MIDI keyboard to their computer and pressing the keys to play the selected virtual instrument . What does this all mean? Well, it means that the process of film scoring has been improved in two significant ways:

  1. Directors no longer need to meet up with composers on a regular basis in order to discuss the progress of the music.
  2. Composers now have a choice to either render their music through the audio production softwares, or continue to record live musicians as composers did before.

Moreover, companies began to create expressive virtual instruments by programming customized features such as attack, vibrato, and frequency range in order to further imitate the sound of real instruments, granting composers the freedom to create a score with just the MIDI keyboard and an audio production software (such as Pro Tools) without the complications of recording a real orchestra.  

After she recorded herself playing the violin part on the MIDI keyboard through Pro Tools, Amber decided to add some expression to the MIDI output by fiddling with the vibrato settings. As she was using a MIDI knob to adjust the amount of vibrato that came out from the string section, a strange thought occurred to her, and she wondered: “What would have happened if Wagner had Pro Tools to play with?”
