The play’s the thing – not only to uncover the conscience of the king, but to inspire music from untold composers down the ages. We refer to this kind of music, somewhat belittlingly, as “incidental.”

No doubt, there are instances of incidental music having entered the standard concert repertoire – Edvard Grieg’s “Peer Gynt,” Georges Bizet’s “L’Arlésienne,” Felix Mendelssohn’s “A Midsummer Night’s Dream” – but so much more numerous are those that have suffered from neglect. Generally speaking, even under the best circumstances, the music is distilled into concert suites, offering but a few numbers, while some excellent work by some very fine composers goes unheard.

This Sunday morning on WPRB, we’ll listen to incidental music by composers both well-known and perhaps not-quite-so, and marvel at the ingenuity on display, as acts are bridged and scenes are set in flourishes that last no more than a few moments.

The highlight of the morning will be a complete performance of Ralph Vaughan Williams’ “The Wasps,” written for a 1909 Cambridge University production of Aristophanes’ satire. Vaughan Williams re-arranged parts of the music to create a five-movement concert suite – the overture is especially well-known – but the complete, original, 80-minute score had faded from memory until this 2005 world premiere recording. The whole is held together by judicious narration and a pinch of salty dialogue.

Join me for these unstung pleasures. We offer them incidentally, this Sunday morning from 7 to 10 EST, on WPRB 103.3 FM and wprb.com. Needless to say, it will all be very “playful,” on Classic Ross Amico.
