Musical Shouting

[Whiteley, Mike]

I'm pretty new at Lilypond.  I've done a few pieces and

have really enjoyed the software. . great job!

 

However, I'm having problems find out how to insert

"shouting" in a vocal staff.  It is just a note with an "x"

as the notehead as to eliminate the specific pitch.

 

I guess it is like a percussive note, or rhythmic notes,

but I can't figure it out how to insert into my single

staff lyrical piece.
