Work's going a little slow this week as I have a lot on my plate, especially starting my internship (32 hour week). I'm brushing up WordSmith here and there, trying to improve the dictionary analysis quality so renders choose more appropriate words. What worked well for drums is taking quite a bit more messing with to work well for other instruments.
Unfortunately I'm having doubts concerning the viability of grammatical subdividion with non-percussive instruments. While it may be possible, I think it's lacking in structure. Perhaps there also needs to be a higher-order grammatical structure to guide motifs so that they do not lack direction.
The question is, then, how does one classify a higher-order grammar? What symbols make up such a grammar? Perhaps phrases could be classified as "suspenseful," "tense," or "declining." Of course there could be loads of other adjectives. The point is that sentences. Sense do not make? When words a sense of direction lack! Yes, that was a bit of a punny example of how grammar can go wrong.
Rough days ahead for algorithmic composition. Fasten your seatbelts and keep a pale ready for sea-sickness. We will be experiencing some turbulent, nonsensical grammar.
