The title Notebook for Anna Magdalena Bach () refers to either of two manuscript notebooks that the German Baroque composer Johann Sebastian Bach presented to his second wife, Anna Magdalena. Keyboard music (minuets, rondeaux, polonaises, chorales, sonatas, preludes, musettes, marches, gavottes) makes up most of both notebooks, and a few pieces for voice (songs, and arias) are included. The Notebooks provide a glimpse into the domestic music of the 18th century and the musical tastes of the Bach family. History The two notebooks are known by their title page dates of 1722 and 1725. The title "Anna Magdalena notebook" is commonly used to refer to the latter. The primary difference between the two collections is that the 1722 notebook contains works only by Johann Sebastian Bach (including most of the French Suites), while the 1725 notebook is a compilation of music by both Bach and other composers of the era. The 1722 notebook: French Suites and miscellany This notebook contains 25 unbound sheets (including two blank pages), which is estimated to be approximately a third of the original size. It is not known what happened to the other pages. The back and the corners are decorated with brown leather; greenish paper is used for the cover. The title page is inscribed in Anna Magdalena's hand. For a reason so far unknown to researchers, Johann Sebastian wrote the titles of three books by theologian August Pfeiffer (died 1698) in the lower right corner of the title page: is a shortened and misspelled title of (Anti-Calvinism, or Conversations about the reformed religion). " item" refers to Pfeiffer's ("Evangelical Christian School"). AntiMelancholicus refers to (Anti-melancholy, or [something or someone] to drive out the melancholy]). The notebook contains the following works, most in Johann Sebastian's hand: Five keyboard suites. The first three are fragments of the pieces that are now known as the first three French Suites, BWV 812–814. The next two are complete suites, French Suites Nos. 4 and 5, BWV 815–816. The minuets of suites 2 and 3 are separated from the rest of their respective suites and were most probably added at a later date by Anna Magdalena Bach (they are almost certainly in her hand), some time before 1725. Fantasia pro organo, unfinished, BWV 573. A short organ piece, 12 complete bars and the beginning notes of the 13th bar. Air with variations in C minor, unfinished, BWV 991. The
