Toccata and Fugue, Op. 59
Among the 12 pieces Reger published as Opus 59, the Toccata and Fugue are often paired off and performed together as a separate piece. The former combines scalar motion and imitation with stridently dissonant chords roughly centered in D minor. The Fugue in D major slowly unfolds, maintaining a chorale-like texture.
