I'm not a musician so my knowledge is limited.

Notice the frequency's in the Octave (ratio 2:1) from 360Hz (D = 360Hz) (+deltaOmega)

360.00 x (12th root of 2) = 381.40Hz (384Hz)

381.40 x (12th root of 2) = 404.08Hz (400Hz) (E = 405Hz)

404.08 x (12th root of 2) = 428.11Hz (432Hz)

428.11 x (12th root of 2) = 453.57Hz (450Hz)

453.57 x (12th root of 2) = 480.54Hz (480Hz) (G = 480Hz)

480.54 x (12th root of 2) = 509.11Hz

509.11 x (12th root of 2) = 539.39Hz (540Hz) (A = 540Hz)

539.39 x (12th root of 2) = 571.46Hz (576Hz)

571.46 x (12th root of 2) = 605.44Hz (600Hz) (f0=600Hz=Omega.r

605.44 x (12th root of 2) = 641.44Hz (648Hz) (C = 640Hz)

641.44 x (12th root of 2) = 679.58Hz (675Hz)

679.58 x (12th root of 2) = 720.00Hz (720Hz) (D = 720Hz) (-deltaOmega)

Keely mentions a so called "pitch" between two oscillating Atoms. The pitch is the vibration of frequency between them.

The oscillations of an atom has a very high frequency, but the "pitch" frequency is very low (differences between them).

If we vibrate (give impulses) on that frequency we can change the oscillation of the Atom and make it unstable.
