The 'Notebook for Wilhelm Friedemann Bach' (Klavierbüchlein für Wilhelm Friedemann Bach) is a collection of keyboard pieces compiled by Johann Sebastian Bach for his eldest son Wilhelm Friedemann. The collection was compiled around 1720, with most of the pieces being parts of the Well Tempered Clavier and the Inventions and Sinfonias. The authorship of most other works is debated: particularly the famous Little Preludes BWV 924–932 are sometimes attributed to Wilhelm Friedemann Bach himself.
