That is due to the principle of the Mozart effect. The key to the problem lies in the frequency of repetition of Mozart's music. His music is relatively simple, always repeating a certain melody many times, and repeating it in a pattern that the human brain likes.

Studies have found that Mozart's musical patterns repeat on average every 20 to 30 seconds, which is consistent with the length of brain waves and the duration of certain activities in the central nervous system. This is the secret of the magical effect of Mozart's music.

Chinese scientists have discovered that the rhythm of music may be the key to the "Mozart Effect" in rats and humans. Reverse Mozart music showed a negative effect. This research paper, "Mozart, Mozart's Rhythm, and the Reverse Mozart Effect, Evidence from Behavioral and Neurobiology," was published in Scientific Reports, published by the British Nature Publishing Group.

The "Mozart Effect" originated from the experimental conclusion mentioned in a paper published by American scientist Francis Rauscher in "Nature" magazine in 1993: Listening to Mozart K.448 can improve human space Reasoning and memory. In the experiment, Mozart's K.448 piece, the "Sonata for Two Pianos in D Major", was played, which is one of his masterpieces.
