This prelude possibly dates from 1730 and is composed in four voices or lines of music with some sections having all voices sounding, whilst in others three and sometimes only two. It opens with a section that is almost vocal in character before it transforms into a keyboard piece. There are no ornaments indicated in the score although there is an extraordinary amount of detail in the rhythmic figuration. The B section which begins at Bar 29 has some almost toccata like shapes whilst a four octave range is explored in the keyboard writing. The tempo of the realisation and playback is 72 quarter note beats to the minute and the repeats are not played. The repeat bar is indicated by a double bar at the end of bar 28 and there is also one at the end of the final bar in the sheet music score. One challenge for the performer is communicating the layers and lines that exist in the music with an awareness of an eighth note or quaver pulse. Another is to play the movement at a tempo that is appropriate and which can be maintained for the whole movement. Some of the figuration in the score can be a challenge to play if the tempo is too fast.
The piece can be performed AB, AAB and even AABB the latter making it quite a long piece. The music editor when learning the movement started with the final section bars 41-56, before playing bars 29-56 and then the piece as a whole. The specified fingering is appropriate for someone who can manage a reach of a 9th with both hands. A plain score is also appended to the edited music score.
