‘We hardly knew what we should pay attention to first’: Mozart the Performer-Composer at Work on the Viennese Piano Concertos

Abstract

Late eighteenth-century writings bear witness to Mozart's extraordinary skills as a performer-composer. But this dual status has yet to exert a serious influence on our understanding of Mozart's piano concertos. An examination of changes to the autograph scores of his Viennese works catches him in the act of negotiating performance needs as soloist and compositional needs as author. His acute attention to detail and his intense personal involvement and commitment – evident in written testimony and in alterations to the autographs – reveal a performer-composer intent on harnessing very specific musical events (sounds, timbres, instrumental and solo effects) to more general ends that ultimately invite listeners to perceive performance and composition as mutually reinforcing features of a complete musical experience. Modern performers trying to recreate the performer-composer experience – soloists and orchestral instrumentalists alike – are thus encouraged to put sounds, textures and effects centre stage in their own interpretations of Mozart's concertos.
