Lilypond incipits

[J.]

Hi every one and thank you all again for the advice on the text editors.

If some one can help or point me to documentation in how to make 20 note incipits in Lilypond for a large folk song collection I am working to publish from the linux computer I have inherited.

I want to take the opening phrase of each one and create an index which I want to print as a work referance and later to incorporate it into the book.

Thank you all in advance.
