How does music affect a baby before birth?
From about the 16th to the 18th week, the baby hears the first sound in his life. And in the last months of pregnancy, it can recognize the voice of the mother.
There is no concept of "right" and "wrong" music, and classical music is not the standard for pregnant women. The baby mostly reacts to the emotional state of the mother, and if she listens to the classics music through force just because it will supposedly be useful to the baby, she will not appreciate her efforts.
Listen to what you love and what you usually listen to - you should only give up very loud and "heavy" music, especially at night. Usually, pregnant women subconsciously choose calm and relaxing music, loud and rhythmic music becomes annoying.
The sweetest music for a baby is the voices of beloved parents, their lullabies, purrs and tunes. And even if there is no hearing and voice, your songs for the child are the best! He loves your voice and lives with it in his heart.
