Scheffer has, through teaching and practicing in a variety of music courses as well as in his own choirs, ensembles and especially the chamber orchestra The Tingsryd Sinfonietta, gained experience by arranging own and others’ pieces/works directly to a particular crew/special instrumentarium. Not least, he has made adaptations of modern classics like Simon/Garfunkel, The Beatles and Monica Zetterlund so that they fit more traditional ensembles, such as 4-part mixed choir, string quartet, and others.
