Mozart wrote a quintet to show off the skills of a blind glass-harmonica virtuoso; Ravel composed a septet for harp, flute, clarinet and string quartet as harp manufacturers vied for supremacy. Penny Gore introduces a selection of works for unusual ensembles, including those works by Mozart and Ravel, Nielsen's Serenate Invano and excerpts from septets by Saint-Saens, Beethoven and Stravinsky.
