I too, find the Setup instructions at 
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-lilypond.html 
difficult to interpret. 

This page says under Setup; 
- must be on a very recent version of org-mode 
- ob-lilypond is also included in the latest Org-mode by default (it seems its not)
- add lilypond to your list of babel languages 


My Org-mode version 9.1.9  Emacs version 26.3 

lilypond has been added to my list of babel languages 

I found lilypond-mode.el  and syntax is colored, that seems to work 

I have grabbed recent  ob-babel-lilypond.el  from github, and put 
that into /usr/share/emacs/site-lisp/  


How or where do I load  ob-babel-lilypond.el   ? 

Presently, I cannot tangle the org lilypond examples, and have no M-x ly-*  commands. 

Raw text Lilypond will compile and output OK. And org LaTeX export is working.
