A fugue is not strictly a musical form but more a compositional style in which the process of imitation dominates in voices or lines of music described as counterpoint. Understand that the musical conception is in lines. The realisation plays back at 100 dotted quarter notes to the minute. The music editor suggests that if you have the technique and composure try to get to 110 dotted quarter notes to the minute as the music then really does seem to come alive. The dynamic range of this work is very much determined by the texture which varies from a single voice to four voices in varying combinations. In music of this time the score detail tends to be quite minimal and this score keeps to that practice. Buxtehude’s position in music history has resulted in him being overshadowed by J. S. Bach but Buxtehude composed many fine keyboard works that transcribe well to the piano. This is an uplifting piece to both listen to and play having the rhythmic template of a jig and a “modern” sound attributable to the tonal ambiguities that result from the conflicting accidentals often in different lines of the music. For those interested in finding out more about this look up the term “false relation.” The subject entries need to be clearly articulated and a sense of forward movement needs to be communicated at all times by the piano/keyboard player.
In terms of the music setting there are some indications in the score as to which hand plays which line of the music and the player needs to have a clear understanding of the division of labour between the two hands. Ornaments do not feature in the score but can be added at the performers discretion once a clear understanding of the options have been appreciated from listening and analysing recordings and performances.
