About us

Founded in 2005, the Harbois Duo, initially evolved from the German wide education project for young concert artists ("Bundesauswahl Konzerte Junger Künstler"). This exciting Duo was established by the principal Oboe of the Essen Philharmonic Orchestra, Sandra Schumacher, and Johanna Welsch: principal Harp of the Beethoven Orchestra Bonn.

Both the Harp and the Oboe are rarely heard as solo instruments. To experience them in this fascinating combination is unique. Together these two charismatic musicians unite the characteristic supple fluidity of the oboe with the silken radiance of the harp. Even the name of the ensemble reflects the harmonic fusion of both instruments, in its use of the french words for Harp and Oboe:


 Har(pe, Haut)bois


In concert, the Duo Harbois entrances its audience again and again with its exceptional sound. Critics have praised the distinguished qualities of the Duo: "With the perfect Mastering of their instruments and their great ensemble playing, both Musicians fascinate their audition from the very beginning till the furios final". Both Musicians are members of prestigious german orchestras and are also very active as soloists. In the Harbois Duo, they combine their skills as soloists with sensitivity of playing chamber music.

They persuade with authentic interpretations and charismatic joy in performance. 

The repertoire of the Harbois Duo contains many interesting original compositions. They also perform (partially their own) arrangements of more famous  pieces from baroque until contemporary music, which promise an interesting, unusual auditory sensation. 

The communication of diverse and interesting information regarding the instruments and the life and works of the composers being performed serve to enhance the concert going experience and to strengthen the connection between the artists and their audience. 

The Harbois Duo performed at many prestigious festivals and concert series in Germany. There are numerous recordings for well- known  broadcasting organisations, such as WDR.
