Christ lag in Todes Banden (also spelled Todesbanden; "Christ lay in death's bonds" or "Christ lay in the snares of death"), BWV 4, is a cantata for Easter by German composer Johann Sebastian Bach, one of his earliest church cantatas. It is agreed to be an early work partly for stylistic reasons and partly because there is evidence that it was probably written for a performance in 1707. Bach went on to complete many other works in the same genre, contributing complete cantata cycles for all occasions of the liturgical year. John Eliot Gardiner described it as Bach's "first-known attempt at painting narrative in music".
Christ lag in Todes Banden is a chorale cantata, a style in which both text and music are based on a hymn. In this instance, the source was Martin Luther's hymn of the same name, the main hymn for Easter in the Lutheran church. The composition is based on the seven stanzas of the hymn and its tune, which was derived from Medieval models. Bach used the unchanged words of a stanza of the chorale in each of the seven vocal movements, in the format of chorale variations per omnes versus (for all stanzas), and he used its tune as a cantus firmus. After an opening sinfonia, the variations are arranged symmetrically: chorus–duet–solo–chorus–solo–duet–chorus, with the focus on the central fourth stanza about the battle between Life and Death. All movements are in E minor, and Bach achieves variety and intensifies the meaning of the text through many musical forms and techniques. (Full article...)
