eli5 How does the brain separate out frequencies it’s hearing so that we can make out different instruments in a song? It seems like some insanely complex analysis behind the scenes??

Your ears have hairs that resonate with different frequencies. The vibration of these hairs due to sound waves they resonate with disturbs fluid in your ear which a region of your brain is able to translate into sound
An example of how this changes is dogs having hairs that resonate with higher frequencies than human ears, which is why we are unable to hear dog whistles.
