Re: scheme-function to export a note-list?

[Ewald Gutenkunst]

Thanks a lot Reinhold!!!

It works perfectly and is exactly what  I looked for. Ok, I am far away to 
understand it really, but it's a great motivation to lern the basics of scheme.
It seems that lilypond has no limitations ....

In a first step I will try to transfer the principle to other events like ties. 
A tied-note is in a musical sense not a new event, rather an extension of 
duration.Then I can do my work in python/gnuplot: My interest is to show 
harmonic/rythmic/melodic structures in a visuell/graphically way to understand 
the formal aspect of music in a better way. For example: in dodecaphonic music 
it's not very obvious, what's happening. 
I will show you, if there are any results.

Of couse! Here some unreflected ideas:

- new type of RehearsalMarks with infos inside. Then you can analyse determined 
areas of the score
- an algorithm, which looks for correlation of music-motivs/themes and shows 
the result in the original, but colorized score
- a new staff type, which acts as x-y-diagram for math-functions. I have seen 
in the snippelts that it's posiible to create long slurs like 
interpolation-splines
- and my english needs an upgrade...

That would be great to present information of a score inside the same score. I 
will start to think about it!

And there is one other question, if you have the time:

The \ambitus is already a sort of analysis, it shows simply the range of 
pitches. But how is it possible to have the information of the whole staff at 
the beginning of it?  Your new engraver goes step by step through the score and 
displays what's going on at every moment.That's not the same thing.


Thank you and have a nice weekend
