Petra has worked with opera singers as an accompanist since her studies in Ostrava and Luzern.

In 2011 she was one of three pianists performing Philip Glass's opera Les Enfants Terribles in the National Theatre in Prague. Petra was a founder member of the Mercia Ensemble with soprano Claire Wild and clarinetist Emma Pountney, with whom she performed a variety of original repertoire and many operatic arrangements in the UK and Norway.
