Mozart wrote the work with the help of a friend and fellow composer, Lorenzo da Ponte (real name Emmanuele Conegliano). He and da Ponte wrote the opera very quickly, as one of his biographers notes, "The writing must have been mainly done in six weeks - the figure given in da Ponte's memoirs - starting in mid-October. It seems that rather than compose the work straight through Mozart set similar kinds of numbers in groups according to their basic emotional character" (Keys 175). The work is an "opera buffa" (a light or amusing opera, today called a "comic opera"), with very complex multiple plots that Mozart manages to get through to the audience through action and voice. Another critic writes, "The action is both structured around and plotted towards numerous and prominent moments of reconciliation" (Sadie 262). The opera keeps the audience laughing, but they also have to pay attention to the action, as well as the music, to comprehend the final outcome. It indicates how complex Mozart was, and how he could translate the complexity of his mind to his music. The "Jupiter Symphony" is another of his most celebrated works, and he wrote it in the last years of his life, along with several other symphonies. Many musicians feel the "Jupiter" is exceptional for a number of reasons, and that its' finale is one of the reasons. One reviewer writes, "[T]he most significant feature of the opening of the 'Jupiter' finale is that of its double beginning: the movement literally begins twice, and given the tradition of fugal finales, in the 'wrong' order"

Sisman 230). Many people find the many subtleties of Mozart's music difficult to comprehend and listen to, and the "Jupiter" is one of those works. Reviewer Sisman continues, "Mozart was fully aware that people found...

It is true that Mozart's music invokes the "intellect and imagination," today as it did then. His music is lush and flowing, and filled with passion and life.
In conclusion, Mozart's life and work are still legendary, even though he lived over 200 years ago. His music was creative and amazing at the time, and he influenced many other composers with his versatility and energy. Mozart is extremely important to the musical world because his works were so diverse, and so long lasting. In fact, some people believe his music can make people smarter. One writer wrote a book about it, "The Mozart Effect," by Don Campbell. A reviewer of the book writes, "According to the argument in Campbell's book, the world's intellectual and spiritual center, populated with our civilization's most generous and healthful beings, ought to be where Mozart is most revered, studied, and performed" (Linton 10). Mozart's life was short, but his legend and his influence remain, and his works are still beautiful and masterful today.
