The film Resonance follows private lessons conducted by three prominent voice and singing teachers in Germany, depicting their relationship with one of their students throughout a whole semester. While working on the physical aspect of the voice, a sensuous closeness is being created between the teacher and the student. Since music is an emotional enunciation, both teachers and students are being exposed during the lessons. The film utilizes this environment in order to inspect the voice and the way it functions in communication between humans, how it affords a means of expression, and creates a connection which is beyond words - physical and sensual.
