Some of the code in it no longer works with recent versions of Org and LilyPond. Also, the source files used in the examples reside in the author's github page (not editable in worg), so if you want to try them out you may have to make the adjustments yourself prior to running the code. In any case, I pushed a few edits which I think makes the tutorial easier to follow. -- Jonathan
