The space allotted here is not going to be enough to effectively answer the question. I think that one of the best items offered is to suggest some particular aspects of his work that are widely known. One of Mozart's most famous compositions is his unfinished "Requiem Mass in D Minor." It is significant because it was his last work and was being worked upon at the time of his death. The "Requiem" showcased Mozart's talent for being able to create music that formed a type of Neo-Classical point and counterpoint in harmony and melody. His obsessive nature over the work is what many believed caused his health to deteriorate further. Such imagery helps to enhance Mozart's claim as a musical genius, as one who would literally die for his music. In this light, the Requiem is viewed as one of his most famous musical compositions.
Mozart is also known for his operas. Works such as "The Magic Flute," "The Marriage of Figaro," or "Don Giovanni" occupy a central place in the Mozart discography. Each one details how insightful and radical Mozart was in the composition phase of assembling opera on both instrumental and vocalizing levels. Mozart had a way of playing with music, almost as if to make the notes bend to his will and his operatic compositions showcase this talent. The fact that his operas still endure over three centuries old is reflective of the musical talent they displayed then and now. This also represents one of the fundamental reasons why Mozart's operas are considered to be his most famous compositions.
Interestingly enough, one of his most well known pieces is a small one. "Eine kleine Nachtmusik" is one of the most widely known musical compositions that Mozart assembled. It has been so famous and well known that "even if we hear it on every street corner, its high quality is undisputed, an occasional piece from a light but happy pen." It is only a testament to Mozart's genius that a small piece of music could become one of his most famous compositions in a body of work that was truly transformative.
