Plot introduction
An assortment of middle- and upper-class people come to the house of the widowed Mrs Amesbury to hear a new violin concerto by David Shiel. As the music plays their minds wander, and their reveries are theatrically performed. Each act of the play corresponds with a movement of the concerto: ''Allegro capriccioso'', ''Lento'', and ''Allegro — agitato — maestoso nobile''.Characters
