How finsihed the requium for mozrat?

The "Requiem" for Mozart, officially known as "Requiem in D minor, K. 626," was left unfinished at his death in 1791. Composed for the Catholic funeral mass, it was completed by Franz Xaver Süssmayr, a pupil of Mozart, who filled in the missing sections based on Mozart's sketches and instructions. Süssmayr's completion includes the "Lacrimosa," which remains one of the most recognized parts of the work. The Requiem was ultimately performed at Mozart's own memorial service, adding to its poignant legacy.
