The chamber musical collaboration between Theres and Markus had already begun when Markus was still studying to become a music teacher. After graduation he once more devote himself to the alphorn. In consequence the two soon began performing with alphorn and piano.

Since then the repertoire and musical diversity of this formation has never ceased to grow. Their performances fascinate the audience in Switzerland as werll as abroad. Theres’s soulful and intense compositions are particularly touching. After graduating from the conservatory of Berne Theres composed mostly for the family ensemble Furioso Romantica.

In recent years the fascination for the natural tone series was of major importance for the alphorn/piano compositions. Often they were asked for CDs by the audience, which lead to the decision to record their music. In 2014 the extraordinary production, “Beflügeltes Alphorn”, was completed, consisting of Theres’s compositions exclusively.
