Dear Harm;

If one looks at the Functional Harmony Analysis Symbols (as they were invented 
by
Riemann and De la Motte) as a modern computer linguist, then one has to state,
that its expressivity is not as exact as it is necessary. One very simple 
example:

Traditionally, intermediary symbols have to be embraced by brackets. The 
semantic
of these tokens shall be, that the denoted function refers to the next coming
chord / function instead to the tonal center:

C-Dur: T (D) D (D7) D7 T = C D G D7 G7 T

Very simple. But with this semantic one cannot express the often used deceptive
cadence: If you see ae chord row C D e G D7 G7 C, then the sub row 'D e' is a
traditional deceptive cadence. But the correspoding Function Analysis Subrow 
'(D)
Dp' is by defintion wrong.

For musical adequate analysis we must be able to speficy the context:

C-Major: T (D[D]) Dp (D7) D7 T = C D e G D7 G7 C

Another weakness of the existing 'analysis tradition' is, that modulations (=
change of a tonal focus) can not be expressed.

I expanded the traditional System by two elements to solve such musical
requirements:

(a) A Functional Analysis Symbol can be sub specified by the Focus to which it
refers. Such focus are indicated by square brackets [ ]. The Focus can either 
be a
keynote or a functional system.

(B) Each modulation is constructed by a chord which dunction is reinterpreted 
with
respect the next context. Such a link chord is indicated by an arrow and a box

C-Major: T S [Sp=>t] s D D7 t = C F d g A A7 d

I need this kind of expressivity for my own coming work. But if you do not need
such elements, you are not enforced to use them. 

With best regards Karsten
