Of the many musical genres that Bach cultivated during his lifetime, none has enjoyed more lasting influence than the prelude and fugue.
The fugue is a strict form that challenges both the performer and the listener.
The prelude is something quite different -- a warmup, if you will, to prepare the crowd -- and the fingers -- for what's to come.
Where the fugue is direct, the prelude is more of a fantasy and "moody."
Listen online to one of the finest Bach interpreters, Hungarian organist Balint Karosi -- First Prize winner at the 16th International Johann Sebastian Bach Competition in Leipzig. He plays Bach's Prelude and Fugue in B minor, BWV 544 in a concert from Oberlin College.
