The Praeludium in G minor, BuxWV149, is a typical example of the genre, flamboyant, improvisatory passages alternating with ones that are fugal and therefore strict in character. It opens with brilliant writing for the manuals, underpinned from the seventh bar by the pedals’ obsessive seven-note phrase. Here, as so often in Buxtehude’s organ works, one can picture an organist seated at a console completely free of music and giving his imagination full rein. This toccata-like opening is followed by a four-voice fugue, a brisk, largely manuals-only Allegro, and a further fugue, marked Largo, which runs into a free coda.
