In order to meet the needs of performances, Rossini had to write five or six operas within a year. Due to the numerous affairs and tight time, he was unable to carefully conceive and carefully consider every work and every detail, thus leaving traces of roughness and haste in many places.

At that time, most of the prestigious composers tried their best to slander Rossini because they deeply felt that this fledgling young man was undoubtedly their strong enemy. The director of the Conservatory of Music in Naples banned his students from reading Rossini's scores. One "famous person" even accused Rossini of being a "loose musician who does not understand the rules of art and lacks noble taste." Father Mattei wrote angrily to his famous student: "Stop, don't compose anymore! You are unlucky, you have brought shame on my school." In response to this, Rossini wrote interestingly in his reply He replied: "Dear teacher: Please bear with me! In order to make a living, I have to write five or six operas a year. The manuscripts were given to the music copyist before the handwriting was dry. I didn't even have the time to read them again. I will wait for the future. When I am no longer busy like this, I will start writing music worthy of you!" Rossini was not perplexed by these harsh criticisms. He knew very well that the shortcomings in his works were due to haste and confusion. Due to lack of experience. In his score, he marked the so-called musical grammatical errors with a cross in his own hand, and noted next to it: In order to satisfy the requirements of academics.
