Instead of putting a music on my animation, I tried the reverse
process.
I had written this instrumental piece under that very name, and I illustrated
it graphically.
Animation made on Blender 2.82 alpha, rendered with Eevee, 1920 x 1080.
The audio was cooked on Cakewalk Sonar Platinum. Almost 3 months work.
Don't forget the full screen mode !
