The Praeludium in G minor, BuxWV148, opens with two ten-bar improvisatory sections. Its first fugue is based on a subject which makes a feature of repeated notes (and whose falling diminished seventh calls to mind the Praeludium in F sharp minor, BuxWV146). After a brief coda, there follows a second, triple-time fugue based on a subject consisting of lively crotchets, and Buxtehude concludes with a passage based on a stately two-bar phrase heard initially on the pedals alone.
