After an earlier career in Leipzig, which included employment at the Thomasschule, Rosenmller was compelled, after a scandal at the school, to escape imprisonment and take refuge in Italy, where he worked at first as a trombonist at St Marks in Venice and later as composer at the Ospedale della Piet. He was able, in 1682, to return to Germany, serving as Kapellmeister at Wolfenbttel.
Church Music Rosenmller wrote a quantity of liturgical works, settings of German and Latin texts.
Instrumental Music Rosenmllers instrumental music includes sonatas for strings and other instruments, all reflecting strong Italian influence.
