Classical Music Found to Support Fetal Heart and Nervous System Development

New research shows that playing classical music to fetuses can stabilize heart rate patterns, with potential benefits for early development.

A study involving 37 pregnant women in their third trimester found that classical music enhances fetal heart rate variability, a marker of healthy nervous system development.
Researchers played two classical pieces, 'The Swan' by Camille Saint-Saëns and 'Arpa de Oro' by Abundio Martínez, directly to the womb using specialized equipment.
'Arpa de Oro,' a Mexican guitar melody, had a stronger impact on fetal heart rate patterns compared to 'The Swan,' possibly due to its rhythmic or cultural characteristics.
The effects of music included more stable and predictable heart rate patterns during and after listening, along with increased fetal movements post-exposure.
The study suggests that gentle classical music could be a simple method for expectant parents to promote fetal autonomic system development, with further research planned to explore other music genres.
