About this work
Built on a very simple theme, little more than an ascending and
descending chromatic scale, this is an exercise in ornamentation
Sweelinck explores the full range of the instrument (the organ) from
pedals to the top of the keyboard. He brings much variety to the
presentation, and some repetition. This piece doesn't modulate - change
key - and isn't strictly fugal, but the use of various stops (voices)
add interest. The rhythm is steady, the tempo doesn't change at all.
But the piece ends with fast runs of notes, by subdivision of the beat.
This is like geometry or plane-division,
like another Dutchman, M. C. Escher.
