Architecture v. form.  Beethoven sonata in D Op.28

As a picture is worth a thousand words the following two diagrams represent all the writing I need to do on this blog.  There is a commentary on the architecture of the 1st movement of this sonata on the previous blog: size matters.
There are several surprises here, the harmonic direction is reduced to 2 and 3 part harmony, for those who know the sonata the progressions are easily picked out.  Some features: 
the importance of the link sections in propelling the harmonic motion
the relationship between the internal ostinato sections and the 'turn'
the compactness of the development (which is driven by rhythmic compression and expansiion)
the additional development of the internal ostinato passage in the recapitulation.
