The Orgelbüchlein ("Little Organ Book") BWV 599-644 is
a collection of 46 chorale preludes for organ written
by Johann Sebastian Bach. All but three of them were
composed during the period 1708–1717, while Bach was
court organist at the ducal court in Weimar. The
remaining three, along with a short two-bar fragment,
were added in 1726 or later, after Bach's appointment
as cantor at the Thomasschule in Leipzig.
The collection was originally planned as a set of 164
chorale preludes spanning the whole liturgical year.
The chorale preludes form the first of Bach's
masterpieces for organ with a mature compositional
style in marked contrast to his previous compositions
for the instrument. Although each of them takes a known
Lutheran chorale and adds a motivic accompaniment, Bach
explored a wide diversity of forms in the
Orgelbüchlein. Many of the chorale preludes are short
and in four parts, requiring only a single keyboard and
pedal, with an unadorned cantus firmus. Others involve
two keyboards and pedal: these include several canons,
four ornamental four-part preludes, with elaborately
decorated chorale lines, and a single chorale prelude
in trio sonata form. The Orgelbüchlein has a four-fold
purpose: it is a collection of organ music for church
services, a treatise on composition, a religious
statement, and an organ-playing manual.
In these chorale preludes, the traditional Lutheran
hymns are subjected to various types of polyphonic
treatment, with different types of countersubjects and
imitative devices. The two pieces chosen by Mr. Escaich
show two different compositional approaches: in the New
Year chorale In dir ist Friede ("In You is Peace"), the
melody is heard in close four-part imitation,
elaborating on the very first two measures of the tune
in particular. The Easter hymn Christ ist erstanden
("Christ Has Risen"), by contrast, is given in three
variations; what is remarkable is that not only the
countersubjects change from one variation to the next
but the melody itself undergoes slight modifications.
However, the chorale melody doesn't wander from voice
to voice but stays in the treble all the way
through.
The chorale prelude BWV 637 is one of the most original
and imaginative in the Orgelbüchlein, with a wealth of
motifs in the accompaniment. Scored for single manual
and pedal, the unadorned cantus firmus is in the
soprano voice. Beneath the melody in a combination of
four different motifs, the inner parts wind sinuously
in an uninterrupted line of semiquavers, moving
chromatically in steps. Below them the pedal responds
to the melodic line with downward leaps in diminished,
major and minor sevenths, punctuated by rests. Bach's
ingenious writing is constantly varying. The expressive
mood is heightened by the fleeting modulations between
minor and major keys; and by the dissonances between
the melody and the chromatic inner parts and pedal. The
abrupt leaps in the pedal part create unexpected
changes in key; and halfway through the chorale prelude
the tangled inner parts are inverted to produce an even
stranger harmonic texture, resolved only in the final
bars by the modulation into a major key.
