The Toccata in G major, BWV916 is different from the others in that it is
clearly in three movements. The opening allegro is somewhat concerto-like in its
use of solo and ritornello passages. Scales, broken chords, and cascading solid
chords are used to make a brilliant opener. The second movement is a lyrical
adagio in E minor where a fair amount of embellishment seems to be called for.
The Bärenreiter edition gives no fewer than three different versions – including
one by Bach’s son Johann Christoph. The final fugue (marked ‘Allegro e presto’)
is a gigue in the French style, using the characteristic dotted rhythm. Like
many of Bach’s early fugues, this one has some passages that are awkward to
play, yet it certainly doesn’t lack charm. At the end the texture unravels very
quickly, leaving us surprised at the finish.
The Toccata in F sharp minor, BWV910 is, I think, the least well-known of the
seven. It’s written in an unusual key for Bach’s time, and contains two fugues,
quite different in character. After the ‘warming up’ section of scales and
descending figures (which would certainly not be out of place on the organ), we
come to a noble adagio that is very chromatic, the subject of which will
reappear in the final fugue in a different guise. The rhythm is that of a
sarabande. Bach’s embellishments seem only to be a start, and the performer can
certainly add more here according to his taste. The first of the fugues is
marked ‘Presto e staccato’ and its pointed subject no more than a descending
scale with a short cadential trill attached. The semiquavers around it add
brilliance. There is some rhythmic interest in a hemiola passage which suddenly
sounds as though the time signature has switched from four to three beats in the
bar. Following that, we have a rather startling section in which the same
arpeggiando figure is stated 21 times in a strange series of harmonic
progressions, a procedure we also find in the D minor toccata. This leads us to
the final fugue in 6/8 time, where the chromatic theme of the adagio is livened
up, but made to be no less expressive. Wanda Landowska writes of the toccatas as
being ‘incoherent and disparate’ at first sight, mentioning this toccata as an
example of that. The difficulty is in finding their shape. She goes on to say:
‘What strikes us above all is the unrelenting insistence with which Bach holds
on to a motive, repeating it indefatigably on every step of the scale.’ That is
certainly true, though the writing, as shown in this toccata, is nevertheless
impassioned.
The Toccata in E minor, BWV914 is another well-constructed and appealing
work. The main curiosity here is the origin of the concluding fugue. Large parts
of it seem to be borrowed directly from an anonymous composition discovered in a
Naples manuscript. The subject, which certainly has elements of the Italian
violin style, is almost identical. The episodes, however, contain material by
Bach that is more refined and complex than anything written by the mysterious
Italian. Preceding it are three sections: a brief introduction in the lower
register of the keyboard; a double fugue marked ‘Un poco Allegro’; and a
cadenza-like adagio that is written over a descending bass line. The latter is
marked ‘Praeludium’ in one copy made by a Bach student, which leads us to think
that it was perhaps, along with the fugue, an independent composition before
being recycled as part of the toccata.
The Toccata in D minor, BWV913 was possibly the first to be composed. It is
one of the longest of the seven but, in a lively interpretation, holds our
interest throughout. The counterpoint in its two fugues is slightly less
complicated, making it easier for students to grasp. The other sections,
however, require an excellent sense of timing and understanding of harmonic
progressions which need to be innate. There are quick changes of mood and tempo
in the opening pages, the bulk of which are occupied by a passage including the
‘sighing’ motif that was very prevalent at the time (and which we also hear in
the early Capriccio on the Departure of his Beloved Brother, BWV992).
Both fugues are built on fairly short subjects that stay rooted in D minor,
rapidly moving from voice to voice. The concluding one is very orchestral in
style, ending abruptly in the major key. In between the fugues we have another
of those curious bridge passages where Bach seems to wander (as much as he ever
wanders!) from key to key, repeating the same figuration. In this case the
wandering has the effect of calming us down, and preparing us for the final
allegro.
The Toccata in G minor, BWV915 has many distinctive features, including a
cyclic feeling (the opening flourish returns at the end of the piece), and a
concluding four-part fugue that obstinately remains in dotted rhythm throughout.
In between we have a short adagio, and a cheerful allegro in B flat major which
is in total contrast to the difficult, but very exciting fugue. Concerning the
latter, only Bach could write so imaginatively on what seems at first like a
very dull subject. With him, repetition of a motive only builds excitement and
strength rather than causing us to lose attention. This is one fugue that, for
me, is a perfect example of what the piano can bring to Bach. On the harpsichord
it is relentless. On the piano one can lighten the second and fourth beats,
giving the subject a welcome buoyancy which serves to enhance its power and
character. The episodes can also be coloured differently, especially the one in
E flat major which provides some welcome relief. The insistent character of the
fugue is emphasized in a passage right before the end where part of the
countersubject is presented in both hands simultaneously in parallel thirds.
The Toccata in D major, BWV912 is no doubt the most popular today. The
brilliant opening bars, reminiscent of the Prelude and Fugue, BWV532 for organ
in the same key, already contain a tremolo figure that will reappear later on.
Then comes an allegro that happily exchanges the motifs between treble and bass.
After its final flourish, Bach introduces an adagio in recitative style – the
melody being interrupted by the tremolo figure, now heard as a distant murmur
rather than a brilliant rattle. An expressive bridge, using the ‘sigh’ motif,
leads us into a fairly tranquil fugue in F sharp minor. Another transition, this
time marked ‘con discrezione’, suddenly turns into a presto in which the
excitement can hardly be contained. It then breaks loose into a gigue fugue of
tremendous energy and rhythm. Then Bach goes one step further and writes a truly
virtuoso passage to finish with – or at least almost, as he returns to the
improvised adagio style for the final cadence.
