Energy-Continuous or discrete.

Does resonance energy imply discrete or continuous energy levels. To me discrete. resonance of discrete energies leads to harmonies,like an orchestra giving rise to a symphony. Continuous energy levels are like fractal patterns giving rise to variations. All of life was made on continous varied fractal like energy levels which got organized to discrete energy levels, which when in resonance sound like a symphony. Higher order life is necessary for expression of this symphony.
