1 - The Music

In the music therapy proposed by Sylvain Guinet, music plays the most important role as it becomes the medium that will guide you directly to your heart, the center of your emotions. Depending on beliefs and the level of openness, sensitivity, and acceptance, the feelings experienced during a session will differ from person to person.

2 - The 3D sounds of nature

Digital technology can leverage the use of binaural sounds for a general audience, a technique that restores natural listening in three dimensions.

Achieving a 3D sound experience with a simple headset is possible! Thanks to holophony in particular. Holophony consists in restoring sound based on a physical model of the human anatomy. Recordings are made using two microphones placed in the ears of a "mannequin head". During recording, each microphone perceives the same sound but with a slight phase shift due to the distance between the ears/microphones and the speed of sound in air. The result gives a real 3D sound experience and total immersion!

3 - "A" at 432 Hz (tuning fork)

Since the Second World War, almost all musicians on the planet have tuned their "A" at 440 Hz, but some still resist and continue to tune their instrument the old fashion way, also known as the "432" tuning.

We know that in 1939 Goebbels imposed the change of the tuning of the "A" at 440 Hz, but other sources mention that this change may have happened earlier, well before the Nazi regime.

In any case, some scientists have raised the question of the consequences of these different tunings. The Schiller Institute considers that the tuning at 432 Hz is deeply intertwined with nature, and advocates for discarding the tuning at 440 Hz as it may create unhealthy effects in the environment and in living beings whose brains and DNA are deeply connected to the 432 Hz tune.

Different people have different opinions about the frequency to use for the tuning fork of reference, and the composer Sylvain Guinet made his choice fairly easily. Sylvain is using the 432 Hz tuning as for him the difference is obvious, it is a matter of listening and feeling the difference.  

4 - Binaural sounds (not available on this site)

(natural mechanism called "frequency adaptation response")

In recent years, the use of binaural sounds has been a real success in the world of personal development. Quality binaural music can help in reaching many states of consciousness, from meditation to concentration, with minimal effort from the participant.

A specific mono-frequency sound is diffused in one ear as a pink noise (e.g. 100 Hz) while the same sound is diffused simultaneously in the other ear with a slightly different frequency (e.g. 110 Hz). 

The brain then processes the two information and mixes them to create a third sound corresponding to the difference in frequency of the original sounds, i.e. 10 Hz in the current example. This is the frequency the brain will tune to. A 10 Hz signal will make you reach a state of deep relaxation without making you fall asleep.


  • In full activity, the brain is in a "Beta rhythm" (i.e. higher than 12 Hz). This may include states such as concentration, reflection, anxiety, action.
  • When we take a moment to relax, close our eyes, and meditate, that pace slows down and the brain goes into "Alpha rhythm" (between 8 and 12 Hz). In this rhythm, the activity of the two cerebral hemispheres harmonizes which allows for a more creative, intuitive thought, and openness to different states of consciousness.
  • When the rhythm of the brain slows down even more, the latter goes into the Theta rhythm (between 4.5 and 8 Hz). This corresponds to the state we are in when falling asleep but also to the state we can reach in very advanced types of meditation.
  • Finally, if the pace of the brain slows down even further, the latter goes into a state close to unconsciousness. This is the "Delta rhythm" (lower than 4 Hz), where thought mechanisms are reduced to leave room only for vital functions.


Details: Binaural beats may be of interest in neurophysiology for work related to hearing capabilities. Their alleged influence on brainwaves, relaxation or health has not been scientifically proven and is mostly evoked in non-traditional medicine.


5 - The Fifth Element (not available on this site)

The composer chose to not disclose the last element of the music therapy proposed on this website for the following reason: We are all part of a world where anything coexists with its opposite. If this last element can bring positive solutions to the well-being of individuals, it may as well create negative effects if used with bad intentions or misguidance.
