This is just me, but I think you've chosen the wrong music for your electronic display.
You're using music with natural tuning, not scientific tuning that has perfect harmonics.
If you used a Jimi Hendrix piece from Electric Ladyland all aspects of your display would be enhanced.
The Fender Stratocaster was the first stringed instrument made in all of human history,
that had individual, two-way adjustable bridges.
This allowed you to plug it into an oscilloscope and tune it like tubes in a television.
That's why he could use so many overdubs and effects and it all sounded wonderful.
