Complex harmonic motion (2019)
Complex harmonic motion is a video piece detailing the motion of a mandolin string under the effect of two Ebows (electromagnets) balanced above it - one Ebow is stationary and illuminates the area of string the camera is focused on and the other is slowly moved along the string during filming to create changing patterns of harmonic motion. I also use the instrument tuners to alter the pitch of both the vibrating string and those around it which changes the tension in the instrument and so also affects the behaviour of the string.
The full video is 16:20 long and in 4 parts; each part explores different types of waveform activity under different conditions. This clip is from part 1.
Recorded by Richard Scott in July 2019 with a Canon 5D Mk III camera, Canon 100mm macro lens and Olympus LS-100 sound recorder.
