Can you sing to me the melody of the last movie you saw in a theatre? I bet you can't.. But I bet you can sing the melody of many movies of the past (Jaws, Raiders of the lost ark, The Godfather etc...) Modern composer have shown us how
the atonal sound is a very important element to create emotions.
Thanks also to the evolution of the speakers (able to reproduce lower frequencies) a lot of importance in contemporary filmmaking has been given to NON MELODIC sounds like pads, textures, drones etc... This kind of sound design is also less invasive on the dialogues since uses often frequencies that aren't in contrast with the vocal range.
▲ Craft a personalised soundtrack on a particular style of music even if it is not directly related to the topic, adds personality and something unexpected to the audience. A good contrast between the images and the sound.
▲ I like to use the footage in order to inspire me create the right music. I even think about the music while shooting. Always trying to keep a parallel creative approach. in any part of the production.
▲ Using the sound to describe a location. The space of a desert can be translated into a wide low frequency pad. The notes of a piano without a formal melody add more atmosphere to the story.
▲ I consider the voice over (when is present) an element of sound design. As expressed in the 7% rule it can have two different form of communications. Direct so what is being said, and indirect so what the acoustic design of the voice communicates.
