In Noctem [Alf:00-51454]

This shadowy cinematic selection, whose title means "into the night," was featured in Harry Potter and the Half-Blood Prince. With a secular text in both English and Latin, the haunting minor-key theme is harmonized in shimmering thirds, and floats above distant staccato chanting. A minimalist piano part mirrors the film score's bell-like treble motive and pizzicato bass notes.
