Klavierbüchlein für Wilhelm Friedemann Bach (Bach's
original spelling: Clavier-Büchlein vor Wilhelm
Friedemann Bach) is a collection of keyboard music
compiled by the German Baroque composer Johann
Sebastian Bach for his eldest son Wilhelm Friedemann.
It is frequently referred to simply as
Klavierbüchlein.
Johann Sebastian began compiling the collection in
1720. Most of the pieces included are better known as
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. The book begins with a preface that
contains an explanation of clefs and a guide to playing
ornaments. The pieces of the collection are arranged by
complexity, beginning with the most simple works. Of
these, Applicatio in C major BWV 994 and Prelude in G
minor BWV 930 are particularly notable because they are
the only surviving works that feature the fingering in
Bach's own hand (the only other Bach piece with
fingering marks is the C major Prelude BWV 870a,
however, the marks are not in Bach's hand. They were
probably added by Johann Caspar Vogler, Bach's pupil
and successor at Weimar).
The Applicatio in C Major (994) might be viewed as a
continuation of the introductory matter preceding it.
The term is perhapsnot a title but a Fingering
demonstration in a little piece of eight measures in
which virtually every note bears a fingering numeral.
Despite its brevity the piece shows Bach's imprint.
Unlike the anonymous prelude from which it may derive,
it falls into a symmetrical binary form. The second
half opens with an inversion of the opening motive,
which is treated in quasi-imitation in both
sections.
