And something else to consider.....In a Vacuum you will SEE exactly the same things as you do in the "normal" world
However, in a Vacuum, you will hear absolutely Nothing!!! Sound travels in air to our ears........but also to our bodies
So it must not be forgotten that Sound Waves are an Energy that our body FEELS as much as we hear it through our ears.
IMHO, it is no coincidence that Music and Melody has the power to make us FEEL happy or sad; uplifted or downbeat; energetic or lazy
The power of the Visual in of itself has nowhere near the same power to move us (The story the visual tells us might, but not the visual itself)
Is it any wonder, that many of us can listen to the same music for 5,000 times over 50 years, whilst most will never watch a movie more than twice
Summary: LISTENING for Differences is one thing, but we should also be thinking about how a Music piece might make us FEEL, when played on different equipment
