Medical research on fetal brainwave recordings at 154 days gestation confirms: auditory responses become detectable in brainwaves between 20–24 weeks gestation. By approximately 24 weeks, the cochlea's structure and auditory nerve differentiation are largely complete.Therefore, starting from 22 weeks, music-based prenatal education should incorporate activities where both mother and father teach the fetus to "sing" musical notes.Although the fetus cannot physically open its mouth to sing, consistent practice by parents will yield positive results. The specific method involves the mother or father practicing vocalizing musical notes. For example: "1, 2, 3, 4, 5, 6, 7, i" or "i, 7, 6, 5, 4, 3, 2, 1".Repeat the teaching softly several times, pausing a few seconds after each note—allowing time for the fetus to echo. During instruction, the mother should fully engage her imagination, picturing the fetus in the womb miraculously opening its bud-like mouth to harmoniously follow the parents' reverent melody. Parents may also select simple melodies to sing.Over time, these auditory stimuli can form memories in the fetus's brain, laying the foundation for future musical development.
Important note: Maintain a quiet environment during teaching sessions to minimize noise interference. Conduct 1–2 sessions daily, each lasting 3–5 minutes. Establish a consistent schedule and create a teaching plan, with both parents taking turns.
