Recording the sound
Once we had most of the shots of our film ready, we came back to the sound design in order to record what we needed. As mentioned earlier, the sound evolves and becomes more high pitched as the threads in the story get thiner, therefore, we decided to record a wide amount of sounds to choose from.
We recorded the "string sounds" with a guitar, with some distance from the microphone and kept changing the intensity to experiment how it matched with the images. To be on the safer side, we covered a lot more sounds than we actually used also so that we have options to choose from later in the editing.
Using one string of the guitar, we recorded the "tension" sound: we specifically wanted this effect for the final shot when the character is hanging from the thread. Our goal was to leave the audience with this resonance of all the sounds together in the background and the tension of the chords movement, wondering what's going to happen next.
In the same session, we recorded the sounds made by the character in the film (breathing, sighs and textile movement). It was a quite easy and fast process in our project, witch is always good when you're dealing with a small amount of time and a huge amount of work. After the recording, we cleaned the sounds digitally and got counseling from a sound profesional to edit the final version properly.
