Clashing the Harmonies: Discovering the Electromagnetic and Harmonic Influence in a Vibrating System to Discover Interaction Between Pitches in Music

 

Abstract

 

The purpose of the experiment was to find out if there is a harmonic and electromagnetic (Lorentz) influence of one vibrating guitar string on another, and if music is affected by these influences.

The experiment consisted of an apparatus built to suspend two guitar strings next to each other. The strings were tuned to three different musical intervals: an octave, fifth, and tritone apart. Harmonic influence tests were done by plucking the lower frequency string. An ESD gun charged the strings for the electromagnetic test. Guitar pickups behind each string served to connect data to an oscilloscope to be graphed.

The only harmonic influence found was with the octave interval. The average frequency obtained was 385.17 Hz, significantly far from both guitar string frequencies. The fifth interval yielded an average of 345.64 Hz, close to 349.23 Hz, the frequency of the lower string. The tritone gave a similar result, with average 340.39 Hz and lower string frequency 349.23 Hz. Therefore, no harmonic influence was measured in these intervals. No waveforms or data was collected for the electromagnetic testing, implying no detectable electromagnetic effect.

The hypothesis was rejected. Only the octave showed harmonic influence, and no intervals showed electromagnetic influence. Instead, mechanical coupling was the most prominent influence found. It was concluded that music is mostly influenced by mechanical transfer and coupling, which was not originally thought. Overall, the experiment data could be useful for further applications in electromagnetic engineering industries.
