March is Early Music Month. While the concept may seem somewhat remote from the world of film music, this week on “Picture Perfect,” we’ll set the Wayback Machine and enjoy four scores that employ melodies and modes of the Middle Ages.

We’ll hear selections from “Becket” (1964), by Laurence Rosenthal. In the film, based on a play by Jean Anouilh, Richard Burton plays the Archbishop of Canterbury, and Peter O’Toole, King Henry II. The music is reliant on chant, with a quotation from the familiar Gregorian melody “Dies Irae” (“Day of Wrath”), occurring fairly early in the action.

Then we’ll hear music from “The Hunchback of Notre Dame” (1939), by Alfred Newman. This time based on a novel – “Notre Dame de Paris,” by Victor Hugo – the film features Maureen O’Hara as Esmeralda and Charles Laughton as Quasimodo, with Cedric Hardwicke, Thomas Mitchell, Edmond O’Brien, and Harry Davenport in the supporting cast. The project was one of nine scored by Newman that year, which many historians regard as Hollywood’s finest. Again, the composer evokes the era through sacred choral passages and secular dances.

“The Warlord” (1965) starring Charlton Heston, Richard Boone and Rosemary Forsyth, is the tale a knight who falls in love with a peasant woman, and in order to keep her, claims his right of “droit du seigneur” – his prerogative to spend the first night with any bride among his serfs. Unfortunately, she falls in love with him, and all hell breaks loose.

It was an unusual project for the composer, Jerome Moross, who is best-known for the kind of breezy Americana sound employed in his best-known music, that for “The Big Country.” Here, he evokes the 11th century with an underscore that, again, finds inspiration in authentic music of the era.

Finally, we’ll turn to “The Lion in Winter” (1965), adapted from a play by James Goldman, an historical drama set at the Christmas court of Henry II – again, as in “Becket,” played by Peter O’Toole. Henry spars with his estranged wife, the temporarily paroled Eleanor of Aquitaine (played by Katherine Hepburn), in a familial power struggle, which also involves their three sons, played by Anthony Hopkins, John Castle, and Nigel Terry. Timothy Dalton appears as Philip II of France.

The film was the winner of three Academy Awards, including one for Best Original Score. The composer was John Barry. Yet again the music is steeped in that of the Middle Ages, yet given a distinctly modern twist.

Plentiful intrigue and funny haircuts are guaranteed. However, there’s nothing Middling about the music. Film composers make history, this Saturday evening at 6:00 EST, on WWFM – The Classical Network and wwfm.org.
