Mozart’s Piano Concerto No. 13 was composed in Vienna between 1782 and 1783. Featuring a solo pianist with orchestral accompaniment, this piece is unorthodox in that, after the theme is introduced, it rarely returns beyond a few brief measures. The soloist has plenty of opportunities to show off virtuosity and style. This concerto also utilizes the concept of fugato, which applies part of a fugue (typically the exposition) to a piece that is not fugal in nature and, through this, develops the theme of the piece.
