This set of variations expands three distinct elements:

• A tone row:

  

• A rhythm:

  

• Three sonorities:

  

The three elements are presented together in the theme, and developed separately in each variation:

Theme:	All elements
Variation I:	All elements equal, but separate
Variation 2:	Rhythm development
Variation 3:	Row development
Variation 4:	Sonority development
Variation 5:	Theme recap

The harpsichord and piano should be viewed as extensions of each other; this is not so much a duo as it is a super-keyboard which requires two people to play.
