Researchers at the Tel Aviv University discovered that premature babies may benefit by listening to western classical music by legendary composer Wolfgang Amadeus Mozart. This is also called the Mozart effect.

They found that exposure to 30 minutes of Mozart’s symphonies helps and they burn less energy everyday thereby needing fewer calories for development.

Lead researcher Dror Mandel said, “The repetitive melodies in Mozart's music may be affecting the organizational centers of the brain's cortex.”

He explained that Mozart’s music is composed with melody which is highly repetitive. Unlike other composers, like Beethoven, Bach or Bartok, Mozart’s music has a repetitive melody which may be the musical explanation to the effect it causes.

Mandel also claims that babies may be less agitated if exposed to classical music. Mozart’s music may make babies calmer.

Premature babies require immediate weight gain to develop immunity against diseases and infection found easily in hospitals.

Researchers will now study the effect of music on unborn babies and their development. They will survey mothers to find out what kind of music were their babies exposed to in the womb.
