The result seems to me to be more like Reverb in my perception/use. Where the lower it is (like R= 0.5), the more restricted the space is so it bounces around more/intimate and the higher values are more like the room is expanding so its not as bouncy.
What does R refer to or what is it a spectrum from->to? What does the absence and abundance of resonance reify as observably?
Basically anything that affects waves is used for music.
