. . . the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts.
But "resonances" also suggests something different, it is to "resonate", to identify with something, or
to have particular meaning or importance for someone : to affect or appeal to someone in a personal or emotional way.
And one resonates with this sculpture, perhaps one thinks of a beach and waves approaching where one is sitting, or it might suggest a metaphysical perception of life and open the viewer to new ideas.
Resonances works on different levels of meaning. As an object it is utilitarian, it is a partition separating the entrance to the new building from the larger green area of the older building to which it is attached. I think the sculpture gives the entrance a feeling of privacy and intimacy; the entrance to the new building is secluded, the ornamental grass giving it a feeling of solitude, of being in nature. It is a wave, showing how a new idea may begin with a single thought and then grow into something much larger and more profound.
Another level of meaning is metaphysical, the sculpture is a long black object, black and in some ways forbidding, but also elegant. You have two elements at work here, water and earth, and they are often considered in opposition to each other. A wave is always changing and this wave changes as sunlight plays off of it. The shadow of the sculpture, black like the sculpture, is a second wave, and both are impermanent, temporal, subject to either the long term change of material deteriorating or to the short term way sunlight changes one's perception of something. In either case, change is always present, whether short or long term.
