Visual and physical experiences define the way we conceptualise sound.
The VCR symbolises visual experience, and the cassette deck symbolises sound. The journey of the ink from VCR to cassette represents the flow of sound conceptualisation - the way vision and tactility provide the framework for understanding and using sound, both in language and in creativity with sound.
After exploring and exploiting the VCR, and collecting information needed to describe sound, the ink demonstrates musicality through simple tones and an adherence to those metaphors we use - 'up' and 'down' as it follows those directions physically, and metaphorically through sound (pitch), whilst navigating wires and tape within the cassette deck.
All that ink is no good for electronics of course...
Stop motion and live action are blended together, with sounds created from objects seen in the video - particularly tape sounds and feedback from the magnetic tape.
