Requiem (Mozart)

Mozart's Requiem is a famous piece of music written for voices and instruments.

It is a Requiem Mass, which is music used for special services. The composer, Wolfgang Amadeus Mozart, began working on it in Vienna in late 1791. Sadly, he died on December 5 of that same year before it was finished. Because of this, the music we hear today is a mix of Mozart's own notes and work added by others. This makes the piece a very special mystery for music lovers to study.

To make this music, a large group of people must work together. The orchestra includes instruments like two bassoons and two basset horns.

It also uses two trumpets, three trombones, and two drums called timpani. For the voices, there are four soloists: soprano, alto, tenor, and bass. A large mixed choir also sings many parts. The music moves through different sections, starting with the Introitus and moving through many other parts. Some parts use soloists, while others use the whole choir to create a big sound.

History tells us how the unfinished music was finally completed. A man named Count Franz von Walsegg asked for the music. He wanted it for a service to remember his wife, Anna, who died in 1791. After Mozart died, a man named Franz Xaver Süssmayr helped finish the work. He wrote many of the parts that Mozart did not complete. Süssmayr even made a clean copy of the music for the Count. He tried to copy Mozart's musical handwriting, but he accidentally dated it 1792.

There are many interesting facts about how this music sounds. The section called the Dies irae, or "Day of Wrath," uses loud brass and drums. In the Tuba mirum section, a single tenor trombone plays alone to sound like a trumpet. The longest part is the Recordare, which is 130 measures long. This part uses a special rhythm called triple meter. Mozart also used a style called a fugue in the Kyrie section. A fugue is a way of writing music where different voices repeat a theme.

Today, people still find new ways to look at this masterpiece. Many composers have tried to write their own versions of how the piece should end. In fact, there are at least 19 different ways people have tried to complete it. Eleven of these new versions were made after the year 2005. Mozart's widow, Constanze, also shared famous stories about the music. She said a mysterious messenger gave Mozart the job. She even claimed Mozart thought he was writing the music for his own funeral. These stories help us feel how important this music is to the world.
