I'm curious whether something is a visual illusion, or if I'm hearing correctly (i.e., that the sounds are different).
https://youtu.be/ns_xsduwI-E?list=RDRMHguvZPcqQWhen it shows up, move the red line near the bottom of the screen to the time of "3:50."
There's two sets of two trumpeters, one on the left and one on the right.
To me, the pair on the right produce the more-pleasing sound.
Or is this just an illusion, and both sides are producing exactly the same sound?
