Unsung Heroines: Danielle de Niese on the Lost World of Female Composers, BBC4, 8pm

THE soprano explores the lives and works of five female composers, from the middle ages to the late 20th century, who were famous in their lifetimes but whose work was then forgotten. Traditionally, western classical music is seen as a procession of male geniuses, but the truth is that women have always composed. Hildegard of Bingen, Francesca Caccini, Clara Schumann, Florence Price and Elizabeth Maconchy all battled to fulfil their ambitions and overcome the obstacles that society placed in their way, but then disappeared into obscurity.

Cruising with Jane McDonald, C5, 9pm

IT’S not a bad life being the star of this show. After all, not only does she get paid to travel the world, but with a Bafta under her belt, there’s little chance of producers pulling the plug for a good year or more. In the first of a two-parter, she’s exploring South America aboard a luxury ship. Beginning in Valparaiso, Jane enjoys a street art tour, before travelling south along the Chilean coast. A few days later she oohs and aahs over a glacier on Laguna San Rafael, and partakes in the traditional drinking of whisky on ice from the glacier. Jane also enjoys a tour of the bridge with the captain as they head for the Falklands.
