Hansjacob Staemmler studied piano with Georg Sava at the Hochschule für Musik Hanns Eisler in Berlin and complemented his training at masterclasses with Daniel Barenboim and Menahem Pressleris. While still a student he gave regular concerts as a chamber music partner of the Ensemble Berlin, consisting of soloists from the Berlin Philharmonic. Since then he has continued to work with renowned instrumentalists and singers in various piano chamber musical ensembles ranging from duo to sextet. Today he is active as a soloist, chamber musician and accompanist. At the centre of his work is an intensive engagement with chamber music in a variety of formations.
In recent years he has performed works by Mozart, Beethoven, Brahms, Dvořák, Dohnányi and Ravel as a soloist with orchestra. New music is an important part of his repertoire and encounters with contemporary composers, some of whose works he has premiered, have greatly enriched his musical creativity. It has also been possible to hear him performing on the fortepiano in recent years. In 2009, performing in a duo with his brother Peter-Philipp Staemmler (cello), he received a prize at the German national music competition Deutscher Musikwettbewerb and was included in the Federal Selection of Concerts for Young Artists promoted by the German Music Council.
After several years as an artistic associate at the Berlin University of the Arts, he has been a lecturer at the Hochschule für Musik in Freiburg since 2009, where he supervises the string classes. He also teaches chamber music at the Hochschule für Musik in Karlsruhe. A sought-after piano accompanist, he is regularly involved in international masterclasses and competitions such as the Deutscher Musikwettbewerb.
