In times of intensified livestock production, the search for methods that reduce stress, which has an adverse impact on the health and welfare of their animals, has become a challenge for breeders and producers. Therefore, the possibility of using various musical genres to alleviate stress in chickens, cattle or pigs was considered. It has turned out that choosing a musical item is extremely important, as it can positively affect the health and production performance of animals by increasing the feeling of relaxation. The time of exposure to sounds and their intensity are important as well, and some authors propose to also pay attention to the frequency of sound waves. Music therapy, which was previously more widely deployed among humans, is increasingly used for farm animals as an element of enriching their living environment. Current research shows the importance of sound waves’ influence in animal production. Proper selection of the music genre, music intensity and tempo can reduce the adverse effects of noise and, thus, reduce the level of stress. It should be remembered, however, that silence is equally important and necessary for the welfare of animals. The paper presents literature findings regarding the influence of music on cattle, poultry and pigs.
This review of the available literature demonstrates that music can be used to enrich the living environment of livestock. With the right choice of music genre, sound level and tempo, music can alleviate the adverse effects of noise and, thus, reduce stress.
It should be kept in mind that silence is equally important and necessary for the well-being of the animals, and that playing loud music to animals—such as rock’n’roll or heavy metal—should be avoided, as it can negatively affect their health. The use of properly selected music in intensive livestock production improves welfare. Intensively housed livestock have to deal with more stress triggers, which weakens their tolerance to stress-inducing factors and, thus, leads to compounding health problems. One interesting line of inquiry would be to create a set of specific musical items and tracks composed specifically for a given species of livestock, tailoring the sound of the instruments, the tune of the song and the sound frequency appropriately.

My take
is that dynamic range of sound like classical music is best for cell growth in plants.
Singing to it and spewing all that good ol' CO2 is the best.
