Bach’s Magnificent C Minor 549
Bach wrote scores of pieces for the organ and the pairing of this C Minor prelude and fugue (BWV 549) probably dates from a time when he was still a relatively young man, maybe 20 or 21 years of age.
He often coupled a prelude (an introductory piece with an improvisatory feeling to it) with a fugue in the same key.
The art of creating fugues was brought to its highest form of expression under the pen of J.S. Bach. A fugue is a kind of elaborate and highly structured round or canon, with one voice introducing the subject (or main thematic idea) and other voices entering later with the same subject. BWV 549 is a four-voice fugue. Listen for the entrance of each voice on the fugue subject.
Bach’s Prelude in C Minor BWV 549 begins with an impressive pedal solo (played by the performer’s feet on the pedal board) that extends a good 8 measures. The other voices, played by the hands on the manuals enter and fill out the sound.
Note: BWV is a catalog of Bach’s works. For your information, Bach also wrote another prelude and fugue in C Minor, BWV 546. The catalog numbers are not chronological.
