Kleines Preludium und Fugue in d-moll

The Eight Short Preludes and Fugues are a collection of works for keyboard and pedal formerly attributed to Johann Sebastian Bach.

They are now believed to have been composed by one of Bach's pupils, possibly Johann Tobias Krebs or his son Johann Ludwig Krebs, based on certain unusual characteristics of the music when played on the organ.

These pieces came to be played often on the organ in the 19th and 20th centuries, and were especially useful as teaching pieces for beginners.

Subsequent scholarship by Speerstra, Vogel and others has suggested that this collection was conceived specifically for the pedal clavichord, thereby making the stylistic claim of inauthenticity far less tenable.
