1) A study found that playing music during fermentation can speed up and improve the process of producing alcohol from fermentation. 2) When yeast cells are exposed to musical energy, it changes fat spots into energy which allows yeast cells to divide more perfectly and in greater numbers, speeding up fermentation. 3) While music has some positive effects on fermentation, playing music all the time could be harmful as it may cause the body to produce too much alcohol, leading to toxic levels.
