State of the art: The automaton generates some (new-music-like) data in form of a midi file.
This is done by a python-script, which is, for demonstration purpose, above all random and probability driven.

This project tries to answer the question, if a piece of music can be considered as a result of a so called grammar.
Furthermore the thesis is, that a piece of music, generated on a given grammar, always sounds kind of 'plausible'.
In general it's said that a piece 'speaks his own language', which in this case would be the language, induced by the grammar.
Following here the hierarchy of Noam Chomsky, the language would be estimated as a 'type-0 language'.
(The restraint in the productions |w1| ≤ |w2| does not exist, and there are no limits for the productions)
Given the grammar, there are constructed entities, called words.
Remember: Each word constructed by the same grammar is part of the same language.
So the automaton will produce a certain amount of words, which (here) will simply be concatenated.
That means that the piece of music is considered as a sequence of words.
(On the linguistic level, this could be considered as the phrase).
Of course for this sequence of words any other arrangement in time is possible.
They could for example overlay, what would be another characteristic of the language...

To keep the things clear, the output is a piano score, wich means the automaton is limited to the
3 (more or less) scalable parameters: Time, Pitch, Velocity.

You are defining a grammar, (and herewith the language of the piece) by:
1.) defining Sigma (the alphabet):
- setting parameters for: Time, pitch range, velocity range, tempo, and so on.
2.) setting the productions:
- which is a programming / scripting -work. In the web version You find some presets.
Most of these things can also be left up to random decisions, what indeed raises the question,
if this would be 'perceptible' language then. ...

Artistically the output of the project will be called 'n Poems for Piano'.
It is sponsored by the GEMA in the context of the 'Neustart Kultur' program.
