Though the next few experiments are not based off of sympathetic resonance, there is still a strong connection between the two phenomenons.
The ‘Singing Rod’ is an experiment that uses friction to create sound. This is based on the concept of nodes, and how a simple amount of frictional force can cause an aluminum rod to resonate so freely.
The ‘Sound hose – Whirly Hose’ is an experiment that uses corrugated pipes to create vortices with the suction of air molecules that finally creates a whistling sound.
The ‘Singing Pipes’ is an experiment that uses the movement of hot air inside, even though the air movement is very slow, to vibrate the metal and create sound.
These three experiments have exposed to creating natural sounds with very little force. This is starting to convince me that creating my device does not need the use of electronics.
Lastly, ’Sympathetic Resonance’, by Joshua Kirsch, is a really cool piece of sculptural-music art. It does not use sympathetic resonance to perform its functions, but uses electronics instead. However, what amazes me is the gentle touch on a metal key can create a natural looking stroke of the mallet.
After watching this, I wonder if this piece could still be functional without the use of electronics and work purely by the matching or corresponding frequencies of an intricate network of finely tuned strings.
