Michael Haydn was five years younger than his more famous brother Joseph.
Both brothers were stars of the Vienna Boys’ Choir in their time, and both went on to spend most of their professional lives working for one employer.
Michael had the better start: while Joseph was still trying to scrape a living teaching the piano and doing free-lance work, Michael landed the job of Kapellmeister to the Archbishop of Grosswardein (now Oradea in Romania). Then in 1762 he was offered a position with better prospects, in the court of Archbishop Schrattenbach of Salzburg. He remained in Salzburg for the rest of his life. He soon was promoted to the position of Konzertmeister in which capacity he was called upon to write dramatic music for the Benedictine University Theatre. This included at one point a collaboration with the 11-year-old W.A.Mozart. When Archbishop Schrattenbach died nine years later, his successor, Heironymus Colloredo, did not support the theatre and it closed. From now on, his output would be mainly for the Church.
He thrived under the rule of Archbishop Colloredo, producing much of his best work, and it appeared he might become Kapellmeister. This stirred jealousies and suddenly there were vicious rumours about his weakness for alcohol and so he was given the position of organist at the Dreifaltigkeitskirche instead. His colleague Leopold Mozart’s nose was instantly put out of joint, because he had hoped his 21-year-old son Wolfgang would get the job at the Dreifaltigkeitskirche – and spiteful things were said.
By the 1790s he was highly regarded both as a composer and teacher – his pupils including one Carl Maria von Weber. His music was in demand in Vienna including at least one commission from his brother’s personal friend the Empress Maria Theresia. Indeed he was much drawn towards Vienna, particularly since Napoleon’s troops had over-run Salzburg exiling the Archbishop. But in 1803 the Archduke Ferdinand stepped in, and on the Archbishop’s behalf gave him a rise in salary which kept him securely in Salzburg until his death on August 10th 1806.
