Would be cool if they could encode amplitude into the display as well. Perhaps with color or shade.
I liked the Beethoven sample as I could follow the different sections of the orchestra and watch visually how they interplay.
Your Bach Tocata example is particularly interesting. I can watch it and see my organ player friend Will running three keyboards, footpedals and stops simultaneously with the visual. Puts all that activity into a whole different perspective to help understand what’s going on there.
Where was this when I (non-musician music lover) was really trying to HEAR classical music thirty years ago???
I was introduced to fugues by the book ‘Godel, Escher, Bach’ (like a lot of geeks I suspect) but I never really got it until I watched these visualizations.
Would love to have this in a framed screen of moving art over my fireplace, and have it go through a playlist each day, programmed according to the scene I want, with the room lights included in the scene setup. :^D
