Notating recitative

[Ari Torhamo]

Hello,

I'm trying to achieve this:

another example:

(my apologies for the lousy images, I can send better ones tomorrow, if
needed)

It's used to mark recitative type of singing (which is like talking, but
on a constant pitch). I don't know if it's commonly used everywhere
(perhaps not, because searching the internet didn't bring up any
examples (wrong search term?)), but it's used in the music I'm notating.

Is this possible to do with Lilypond?

Thanks

Ari
