It is not a music software, but an instrument for prenatal education. It mainly adopts the heart sound prenatal education, uses the heartbeat sound of the mother that the baby is most familiar with as the sound source of prenatal education, separates the contraction sound and the relaxation sound of the heartbeat, and then scientifically combines them to form the unique rhythm of 12 that human beings are most familiar with. This rhythm is set on the basis of fully studying the baby's development. With the development of the baby, it becomes more and more complicated and the playing speed is getting faster and faster. These sounds and rhythms can vibrate with the baby's brain cells to produce a physiological effect called "co-frequency metabolism", which can effectively reduce the apoptosis of brain cells, make the baby form a tighter and smarter brain, and make the baby's imagination richer and memory stronger.
