Dear Friend.

According to Greek mythology. Orpheus could sing with deep feeling and interpreting Lira and cited as an outstanding and accomplished teacher. For this reason, thanks to spell that produced melodies, Orpheus could enter Tartarus. First he enthralled with his music to the boatman Charon, who agreed to take you through the swamps of Acheron. After their songs they bewitched Cerberus, the dog that guards the entrance to Hades. His music had the power to stop the tortures of the damned, Ixion wheel stopped spinning, the stone of Sisyphus remained in balance, Tantalus momentarily forgot his eternal hunger and thirst, the Danaides left to fill their bottomless barrel. Neither the three infernal judges, Minos, Aeacus and Rhadamanthus were indifferent to his music. Impressed the gods of Tartarus, Hades and Persephone, to such love and skill tests, they agreed to return to his beloved.

Moreover, our planet has a 7.83 Hz pulse frequency. That is, emits an inaudible sound like our hypothalamus, according to some authors.

In full accordance with the theory of the "harmony of the spheres" proposed by Pythagoras "

Indeed, the sound is energy. Evidenced by the following equation: E = d V2. That is, the density of the medium where they spread by the square of the particle velocity of the medium where the spread is occurring. This means that in a vacuum there is no sound. The only waves traveling in a vacuum are electromagnetic.

We hear human (ie our sound sensors are sensitive between 20 and 20,000 Hz, usually), however, may feel infrasonic or ultrasonic frequencies, and because it is energy, then everything on earth is very determinedly influenced by sound.

We Can I imagine a sound weapon ?. We can imagine a high-impact sonic boom?

Is of course also imaginable sonic therapy can cure diseases. Very loud environments are harmful, dangerous and polluting and cause disease.

In summary; if we are descendants of this planet have conditions suitable for life sound is generated in it. The sound is essential for life. But also for death.

The rapture caused by a violin, cello and guitar, lyre and harp, piano, oboe, among many other musical instruments, very well interpreted, causing a mental state that can generate hypnotism.

Consequently there can be healing methods for music, and a certain type of music, which substantially improves the immune status.

It is valid for any living being. This field of research is open to anyone.

Best regards

To much loud music creats  vibration with small frequency that might affect the formation of biofilm for some microorganisms.

It will mostly depend on the music. For example if you put Justin Bieber, bacteria will litterally explode while they are pretty happy if you put Pink Floyd :)

No seriously, I don't think it's gonna change anything... But would be curious to know more about it! You told that there is some reports, do you have links?

Best,

Thibault

Not for cell or microorganism but at my country, some high school students made project about islamic sounds on bean seeds. They placed one seed into the box with islamic sound, one seed with no sound. Finally 1 week later the seed that LİSTEN islamic sound growth faster and reach 33 cm length. Other seed had 15 cm length. Seriously in my opinion there must be some correlation between sounds and bacterial growth. And my motto is heavy metal sounds and classical sounds effects organisms differently :)

I have seen research in botany that suggest that when music is played in a greenhouse environment, the plants that are growing with Art music genres being played are healthier than those growing with more popular genres being played. 

I have also seen biological studies that suggest that cells in the body respond to certain speeds of vibration. I would like to think that it these human cells would respond to tonal frequencies the same way (I have not pursued this field so I'm not totally sure), thus music could possibly evoke physical changes in living cells. Which leads me to wonder if this change in a human is more from a physical vibration or psychological state? Your question is very intriguing.

Really appreciate all contributions and discussions here...

@Thibault G Sana, nice analysis by You regarding those singers. But truly we should have to do research on that. There are few reports as below:

@Carlos José La Rosa, thanking you for nice contributions and descriptive ideas you shared here.

@ Cynthia Bridges and İbrahim Türkel, yes there are many reports of music responds by plants but is that proved or just an hypothesis. And how can we correlate this with microorganisms?

what ever it may be this topic is quite interesting to discuss and share. If any one found the full text of the above link I shared, please share here.

Here is another report by

Amir M. Mortazavian, Ph.D. (Dairy & Probiotic Specialist)

Assistant Professor,Department of Food Science and Technology

He introduced a term "green music". Check the file for more.

Dear Dr. Carlos José La Rosa, as you said music susubstantially improves the immune status can it be possible to change the pathogenicity of a pathogen by music.

Every day, researchers are learning more about the chemicals that the neurons (NUR-ons) in the human brain use to communicate with each other. They now know that all the feelings and emotions that people experience are produced through chemical changes in the brain. The "rush" of happiness that a person feels at getting a good grade on a test, winning the lottery, or reuniting with a loved one occur through complex chemical processes. So are emotions, such as sadness, grief, and stress. When the brain tells the body to do something, such as to sit down or run, this also sets a chemical process in motion. These "chemical communicators," or neurotransmitters, are the "words" that make up the language of the brain and the entire nervous system.

 As pathogenicity of any microorganism also due to their any specific chemical structure (may be) which is active when it causes disease which can be destroyed by sound waves. Yes it is imaginary till now.

But can any one suggest how to do these type of experiments initially.

Thanking you in advance.

Thank you for those links, that's very intriguing!

The topic of how microbes respond to the audible sound, has remained a neglected area of research till now. Higher organisms like animals have well-developed ears, and hence they can clearly receive and respond to the sound stimuli. In case of microorganisms, it seems that mechanosensory channels may be involved in sensing and responding to sound. We have started some research in this field, and published our preliminary findings:

Niral Sarvaiya, Vijay Kothari (2015). Effect of audible sound in form of music on microbial growth and production of certain important metabolites. Microbiology, 84(2):227-235. DOI: 10.1134/S0026261715020125

Another paper of us in the same area is under review. We plan to decipher the molecular basis of microbial response to audible sound through transcriptome analysis, i.e. by comparing the gene expression profile of the sound stimulated culture with that of control. For this we have been sanctioned a research grant from Gujarat Council on Science and Technology (GUJCOST).

Bacteria not only can respond to sound, but they can produce it too, as shown in:

J. Gen. Appl. Microbiol., 44, 49–55 (1998)

Till now whatever little work we have done in this area, we have found that different microbes may respond differently to the same sound pattern, and even among the similar responses, the magnitude of response vary.  We found that quorum-sensing-regulated pigment production in bacteria like Serratia marcescens, and Chromobacterium violaceum was altered by sound stimulation.

Developing any microbiological application utilizing sound stimulation as a tool will be possible only after sufficient fundamental research in this area is done. Unfortunately, not many scientists seem to be attracted to this field, presently.

Dear friend:

Among other arts such as geometry and mathematics, music is closely related to science. Some authors strongly support the argument that "harmony of the spheres" gave rise to the concept of gravity of Newton. But also to the reciprocal of the square of the distance, it is a derivative of the monochord music concept. Although Newton disliked Pythagoras, that this did not believe in God, he took his ideas and concept development, as discussed and debatable, of gravity. Ha ha ha ha ha aha. We all talk about gravity, without knowing what it is.

The sound is a product of our planet and our atmosphere and convert it into musical notes, it is a science. The music is a product of the human mind and "the mind touches the brain as the pianist at the piano." So, the brain and / or the hypothalamus are handled by the mind, therefore, as instruments, are heavily impacted and influenced by the sounds (stimuli) environmental.

That is we are sensitive to sound good and the bad. Good sound is music exalts us. The noise makes us sick. But in any case "energy".

The, although rare, references do not necessarily imply that research on this topic is low. It is certainly a topic apparently rare, but very interesting.

We must be careful with scientism

Thick bio-film were observed when a bacterial is exposed to 33KHZ to 50KHZ for 30mins, where as there is a reduction of growth below and above this frequency (as tried max up to 2 hrs with both lower and higher ranges). And as per music it won’t be crossing more than 20KHZ. But may be a prolonged exposure to music for period of 24 hrs- 48 hrs may do its work.. Any way it is interesting..!
