Hi, Eric, Thank you, though I'm afraid I'm still having trouble getting the right result. The closest I've come is with this setting: (setq org-babel-tangle-comment-format-beg "\\sourcefilename \"%file\"\n\\sourcefileline %start-line") But this adds comment characters before the commands. It also adds a blank line after the comment, throwing line numbers off by one. (Actually they are off by two; maybe LilyPond needs \sourcefileline to be on the same line as the beginning of the code.) By the way, I tried binding the variable this way in the Org file: #+BIND: org-babel-tangle-comment-format-beg "\\sourcefilename \"%file\"\n\\sourcefileline %start-line" But that had no effect. A further question: can this approach accommodate code blocks in multiple languages in the same file? Best, Thomas
