How the physics of resonance shapes reality
&quot;Resonance underlies aspects of the world as diverse as music, nuclear fusion in dying stars, and even the very existence of subatomic particles.&quot;<p>I learned recently that the harmonics of consonant musical notes have aligned frequencies. Meaning: the  most consonant notes produce the most resonance between the strings. For example, two strings at a consonant interval of a fifth (3:2) have harmonic resonance every 3rd and every 2nd harmonic band. This is much easier to show with a visual of the spectrograms: <a href="https:&#x2F;&#x2F;docs.google.com&#x2F;presentation&#x2F;d&#x2F;1cdRfvPtek44rH8k2GpMVnuUDsxVGC3M9ZLPt0xf5_jU&#x2F;edit?usp=drivesdk" rel="nofollow">https:&#x2F;&#x2F;docs.google.com&#x2F;presentation&#x2F;d&#x2F;1cdRfvPtek44rH8k2GpMV...</a><p>As oscillations of neurons in the brain will also show this harmonic structure (due to the frequency following responses [1]), consonant notes may also produce the most neural resonance! But, we don&#x27;t have the ability to measure and test this hypothesis yet.<p>[1] Bidelman, G. M., &amp; Momtaz, S. (2021).
