Sympathetic Resonance

January 4, 2019

So, what the heck is Sympathetic Resonance and why should I care?!


Sympathetic Resonance, also known as “The Solfeggio Frequencies”, are tones that vibrate at a harmonious frequency with very specific brain waves to produce a unique positive effect.

Soothing Baby Sleep includes three Solfeggio Frequencies that are meant to be played at the edge of auditory discernment underneath one or more other sounds.

Think of it like a subliminal healing and calming boost that you really shouldn’t be able to consciously notice while the other sounds are playing.


The tones included are:

136Hz “OM Tone”: This tone corresponds to the meditative chanting of monks and priests, said to promote balance, joy, tranquility and spiritual wellness.

432Hz “Earth Tone”: Also known as the fundamental “beat” of the planet, it is said to promote synchronization between the two hemispheres of the brain.

528Hz “Love Tone”: Hailed as the “miracle” note of the original Solfeggio musical scale, said to have the ability heal damaged DNA, it is essential to the sacred geometry of spirals consistent with hydrosonic DNA structuring.

If you’re interested in the full science and history behind it, you can go on a deep dive here:


By themselves, the tones should just sound like a persistent, unchanging sound. Here is a sample of the “OM Tone”:


To gain the healing and calming benefits, the tone needs to be played along with other sounds so that you can just barely make it out. I’ve found that the optimal combination for my daughter is the “OM Tone”, played under the “Womb” sound, with a recording I made of myself doing a shushing sound.

Here is what my daughter sleeps to every night:


This has been an absolute lifesaver, bedtime is no longer a nightmare, but a peaceful experience for my daughter and I. We hope you will be able to find the perfect mix for you and your children as well!
