Jörg Widmann is a German composer who is acutely conscious but certainly not in awe of his musical forebears. His best-known string quartet, no. 3 ‘The Hunt’ makes dramatic use of – and has great fun with – Schumann. His 2011 concerto Flûte en suite, performed at the 2014 Proms, more than nods to Bach and baroque elegance. In Armonica, commissioned by the International Mozarteum Foundation to celebrate Mozart's 251st birthday in 2007, Widmann surprisingly and yet unsurprisingly features the glass harmonica, the distinctive instrument that Mozart featured in his own last chamber piece, the Adagio and Rondo for glass harmonica, flute, oboe, viola and cello, K617. Mozart teamed the instrument with the quieter representatives from the wind and string families; Widmann places it against the whole orchestra.
