Years of research led the Mitchells to an ancient musical system called cymatics, or Chladni patterns, which are formed by sound waves at specific pitches.

ALL music is formed by sound waves at specific pitches. Actually, at specific frequencies, since it is our own brains that interpret these frequencies as pitch.

There is no "ancient musical system" called "cymatics."

"Cymatics" is a neologism referring to the study of the aesthetics of wave patterns, and was first coined in the 1960s.

This is the usual nonsense wherein people who have stupidly wasted their time trying to find a secret pattern will themselves into seeing a pattern where none existed.

I could take a basket of marbles, throw them on the living room floor and - by assigning specific notational values to the random marbles according to color or position - use them to compose a musical piece.

A modified form of this kind of randomization is already a compositional technique in postmodern music: serialism.
