When Mozart died in 1791 he left behind an uncompleted requiem (a large work for voices and orchestra, in sacred honor of someone who has died). What happened at the first performance?

Wolfgang Amadeus Mozart was a talented child and began composing when he was just 5 years old! Mozart went on to write more than 600 works - symphonies, concertos and operas - which are still recognized today as some of the greatest pieces of music ever composed. Sadly, Mozart died when he was just 35 years old.
