Florian Maierl received his first choral conducting lessons at the age of 15 at the Upper Austrian State Music School. This was followed by studies at the University of Music and Performing Arts Vienna (church music, solo singing and vocal pedagogy). A year of study abroad took Maierl to the Sibelius Academy in Helsinki. He completed masterclasses with renowned choir conductors such as Erwin Ortner, Johannes Prinz, Johannes Hiemetsberger, Volker Hempfling, Robert Sund and Veli-Markus Tapio.
Florian Maierl worked as an assistant with several choirs (including the Vienna Singakademie, the German Youth Chamber Choir and the Gumpoldskirchner Spatzen). In 2006, he founded coro siamo, which he has been directing ever since. Maierl teaches conducting and ensemble direction at the Mozarteum in Salzburg and at the Archdiocese of Vienna's Conservatory of Church Music, and is also an occasional lecturer at choir director courses and singing weeks.
Florian Maierl's compositions and arrangements have been performed by the Vienna Chamber Choir, the Upper Austrian State Youth Choir, coro siamo, the Choir of the University of Music and Performing Arts Graz and the vocal ensemble Lalá, and some have also been released on CD.
