Ysasye:
Sonate pour deux violons seuls, op. posthume Sonate für zwei Solo-Violinen

Marschner:
Sinfonische Variationen für zwei Violinen
Drei Bagatellen für zwei Violinen

"The Violinduo Penny-Starkloff not only continues the tradition and embodiment of a special sound image of paired violins, but also animate it in an excellent way. This was the main incentive for me to write my symphonic variations for this combination. "Wolfgang Marschner himself wrote this in his introduction to this work, which was premiered in November 2016 by the two soloists. Marschner is not only a composer but also a virtuoso violinist, who masterfully exploits the tonal possibilities and makes the two violins "sound like a quartet", as Mywanwy Ellapenny says. The focus on virtuoso violin playing is shared by Marschner with Eugene Ysaye, who was one of the most famous soloists in his time. His sonata for two violins also demands all musical and technical qualities, which, like the unusual colors in Marschner's dancer's bagatelles, they master bravely.
