ozart cannot refuse, he needs the money and... the fees are more than tempting. The realization of the composition did not really advance. Mozart was so obsessed and convinced that he was writing his own Requiem. He died, without being able to finish the composition, during a repetition of the Lacrimosa.

Franz Süssmayr, a noble unknown composer in the history of the music, filled his duty with honor and devotion. He finished the Requiem in the style of Mozart.
