What precautions have you taken against Rusalka Week? None, you say? (Crosses self)

There are innumerable pieces of music written about water spirits – sirens, naiads, lorelei, undines, mermaids, and melusinas. This Sunday night on “The Lost Chord,” we’ll sample just a couple of these for Rusalka Week. Rusalka Week begins on Pentecost, 50 days after Easter (i.e. today).

In Slavic mythology, a rusalka is a spirit that dwells at the bottom of a river or a lake. She lures unsuspecting men with her song, invariably resulting in a watery doom. Rusalki are never more dangerous than in early June, when the spirits roam free. Those who die in the week leading up to Pentecost are especially prone to becoming rusalki.

Rusalka Week plays a role in Rimsky-Korsakov’s opera, “May Night,” drawn from Nikolai Gogol’s collection, “Evenings on a Farm Near Dikanka.” Alexander Dargomizhsky’s opera, “Rusalka,” is based on a dramatic poem by Pushkin. And the best known of the bunch, Dvorak’s “Rusalka,” was inspired by Czech fairy tales of Karel Jaromir Erben and Bozena Nemcova.

But we won’t be listening to any of these. (We’ve treated Rimsky and Dargomizhsky in the past.) Instead, we’ll have a flute sonata from 1882 by Carl Reinecke that bears the subtitle “Undine,” an allusion to a novella by Friedrich de la Motte Fouqué, very popular among the Romantics. Fouqué’s “Undine” tells the tale of a water spirit who marries a knight in order to gain a soul.

Then we’ll hear the complete ballet, “Les Sirènes,” from 1946, by Lord Berners. Berners, notorious for his sense of the absurd (a horse was a regular guest at his indoor tea parties) was a talented composer, writer, and painter. “Les Sirènes,” after a scenario by Frederick Ashton, features mermaids combing their hair and singing on rocks at a seaside resort, while on shore, sirens of another sort behave coquettishly.

I hope you’ll join me – you shouldn’t be out wandering during Rusalka Week anyway – for “Come on in, the Water’s Fine,” this Sunday night at 10:00 EDT, on WWFM – The Classical Network and wwfm.org.
