Bach Cello Suites visualized
I’m glad you haven’t taken my interpretations as harsh criticisms. I enjoy visualizations of music, and even the “boring” ones can add insights.
I get the narrow “perceptual now” window. Events within this band are psychologically bigger, as it were, but that’s attentional as much as anything. They are not necessarily changing in physical size or in speed. 
The analogy of the railroad ties would work if your time axis was very gradually foreshortened at the far ends of the visible screen, but in your viz, the notes are all equidistant except within the narrow “now” in the center, and there is a disconcerting discontinuity of the time axis at the edges of “now”. This visual discontinuity causes dissonance with the smooth aural stream I am hearing, so I lose track of the audio. 
As a musician or as a listener, I am “looking” (“listening” or “feeling” might be better terms) ahead and behind to keep pace and to feel the flow of the music. The jumping of the notes disrupts the flow.
I’ve actually watched a fair number of these and similar visualizations, and I still can’t get used to the horizontal distortion. Maybe it’s because I’m not a very good musician and I am highly biased towards the visual in my cognitive processing, but aren’t most humans biased in that direction anyway?
