Sonata in D minor BWV964
Both the Sonata in D minor, BWV964, and 
the Prelude and Fugue in A minor, BWV894, are virtuoso pieces, intended 
to show off the ability of the performer. They are consequently very 
effective in recital. Both exist in versions for other instruments, the 
sonata being Bach’s own transcription of his solo Violin Sonata in A 
minor, BWV1003, and the prelude and fugue appearing recycled as the 
outer movements of the Triple Concerto for flute, violin, solo 
harpsichord and strings, BWV1044. The keyboard arrangement of the sonata
 no doubt annoys violinists as so many of the horrendous difficulties to
 be overcome on the violin are easily rendered by two hands. There are 
many reports handed down of Bach playing his unaccompanied string pieces
 at the keyboard, so although this transcription again only survives in a
 copyist’s hand (that of Altnikol, his son-in-law), its authenticity is 
not really questionable. The polyphonic texture implied in the original 
is here beautifully realized without great changes to the melodic line. 
The second movement was admired by Bach’s Hamburg contemporary 
Mattheson, who praised his ability to construct such a long fugue from 
so short a subject. It is indeed a tour de force, demanding great 
concentration and skill (and probably scaring away many a player). The 
lovely F major andante brings us a moment of complete repose and 
tenderness. The finale is almost completely identical to the original, 
with the one line of music being divided between the two hands. (from notes by Angela Hewitt © 1995)
Prelude in C major BWV924
The eighteen Little Preludes are among the most valuable pieces ever written for beginners. They form a bridge between the easiest pieces of the Anna Magdalena Notebook
 (1725) and the Two-part Inventions, giving the player a wonderful 
introduction to voice imitation, pedal points, cadenza-like passages, 
and basic ornamentation. They cover many different moods, from the 
affirmative (all three preludes in C major), to the tender (the C minor 
minuet, BWV924), the improvisatory (BWV940), the joyful (BWV927 and 
937), and the very grand (BWV928). The C minor prelude, BWV999, was 
originally written for the lute. Many of them are far from easy (the A 
minor, BWV942, for instance), and require quite complicated fingering 
(BWV943). Even in these little pieces, big decisions have to be made 
concerning tempo, phrasing, articulation, dynamics, and timing, and this
 challenges the teacher as much as the student. Bach wrote them for his 
son Wilhelm Friedemann and other pupils, but never grouped them into any
 particular arrangement. Like the French Suites, many of them survive 
only in copies made by another hand. There are several traditional 
groupings of which I have chosen one, changing the order of the first 
six to make a more pleasing progression in performance. For me they 
recall fond childhood memories, and are as fascinating now as they were 
then.

Prelude in E major BWV937
Johann Sebastian Bach perhaps 
remains the greatest composer of what may in the best sense be called 
‘educational music for youthful performers’. His Prelude in E major is the penultimate of Six Little Preludes while the Praeambulum in G minor is from the Little Keyboard Book
 written for his son Wilhelm Friedemann – two groups of pieces well 
designed to cultivate precise phrasing, clear part-playing and buoyant 
rhythm, among other qualities. (from notes by Max Harrison © 1986)
Prelude and Fugue in A minor BWV894
Both the Sonata in D minor, BWV964, and 
the Prelude and Fugue in A minor, BWV894, are virtuoso pieces, intended 
to show off the ability of the performer. They are consequently very 
effective in recital. Both exist in versions for other instruments, the 
sonata being Bach’s own transcription of his solo Violin Sonata in A 
minor, BWV1003, and the prelude and fugue appearing recycled as the 
outer movements of the Triple Concerto for flute, violin, solo 
harpsichord and strings, BWV1044. 
Bach’s creative genius 
flourished during his time as court organist (and later Konzertmeister) 
to Duke Wilhelm Ernst in Weimar (1708–1717). There he not only composed 
most of the great organ works, but also transcribed twenty-one concertos
 (most of them by Vivaldi) for organ and harpsichord. Influences of both
 these genres can be heard in the A minor prelude and fugue, composed 
towards the end of his tenure. The prelude, with its opening motive in 
the right hand immediately repeated by the left, is in concerto style, 
alternating between tutti and solo passages. Triplets give it constant 
direction, interrupted only by cadenza-like passages, the last one 
reminding us of the D minor harpsichord concerto. The gigue fugue is in 
perpetual motion, never once letting up. The fact that Bach again uses 
triplets to propel it forward can, if one is not careful, provide for 
little contrast with the prelude. It is perhaps best to emphasize the 
difference in time signatures (4/4 for the prelude, 12/16 for the 
fugue). Would Bach have been able to improvise such a fugue on the spot?
 I think it most probable, for at that he was unbeatable! (from notes by Angela Hewitt © 1995)
