Michael Haydn was the younger brother of the famous Joseph Haydn, an intimate friend of Mozart, who had a high opinion of his works, and, later on, the teacher of Carl Maria von Weber.
1771 saw the deaths of Haydn’s baby daughter and his beloved patron, Archbishop Sigismund. Although Haydn’s superb Requiem was officially written for Sigismund, and completed only a fortnight after his death, it surely also reflected the loss of his daughter.
Intriguingly Mozart had heard a rehearsal performance of the Requiem and, where such a retentive mind would have remembered both the occasion and the performance, his later unfinished masterpiece reflected a series of musical parallels with Michael Haydn’s moving Requiem.
For SATB Soli, SATB Chorus, and Orchestra, available here is the Violin II Part of Michael Haydn’s Requiem.
