Ralph Vaughn Williams’ Fantasia on a Theme by Thomas Tallis (1910) is a masterpiece of 20th-century English music. Inspired by the Renaissance practice of borrowing and reimagining existing themes, Vaughan Williams drew upon a 16th-century hymn tune by Thomas Tallis. The composer first encountered this haunting Phrygian-mode melody while editing the English Hymnal and later expanded it into a richly textured work for double string orchestra and a solo string quartet.
The piece opens with an introduction followed by two complete statements of the theme, where the music rises to high, shimmering violin textures. Vaughan Williams then masterfully divides his forces, creating a musical conversation where the orchestras echo one another and soloists—particularly the viola and violin—develop thematic fragments. This intricate dialogue eventually culminates in a return of the complete theme, supported by the full ensemble.
Notable for its diaphanous modal harmonies and expansive, glowing string textures, the Fantasia serves as a modern reimagining of the Renaissance instrumental tradition. It remains a deeply spiritual meditation, bridging the divide between the 16th-century Tudor era and the evocative, pastoral soundscape of the 20th century.
