This is pretty much a niche technology. But LilyPond is also a niche technology, so that comment isn't a judgement ;-) Humdrum is a *data format* with a large set of analytical tools written for it. The original idea of creating Humdrum was to create a format usable for computer-assisted analysis. Chances are that there will be Humdrum-to-LilyPond integration in the not-too-distant future BTW. > but I've read something about music21 before.

You can alway try it out, but I wouldn't recommend relying on it professionally. > Embedded as an 'analysis' menu in frescobaldi (similare to page check > rendering), frescobaldi could pass the score to music21, which > analyses it, then sends the results back to frescobaldi, which renders > it with the code generated by music21.lily.translate. I think this will not be happening in this way, as I'm sure Wilbert Berendsen will not want to add such a heavyweight library to Frescobaldi. What should be possible is calling/including music21 from within a "Snippet" that you can create/add to Frescobaldi. That should work already. Another option is the plugin infrastructure that has been on the wish list for quite some time now. > > Having analysis options and counterpoint checks, voiceleading checks > etc. added to OpenLilyLib would on the other hand be very interesting > because of less dependencies on external technologies and no > conversion issues. Indeed. But if these external technologies have already solved the actual problems one tries to solve that is a strong point. I think it should still be possible to use openLilyLib as a wrapper, i.e. the interface to integrate to LilyPond documents and call external tools through Scheme. Just as another option.
