Dear Harm;

If one looks at the Functional Harmony Analysis Symbols (as they were invented 
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 

Traditionally, intermediary symbols have to be embraced by brackets. The 
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 
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

(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 
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
