Problem with Classical guitar notation

[Allan Spagnol Comar]

Hi all, I am having a little trouble engraving some classical guitar
sheets. I am trying to edit some sheets and they have the notation
showed at the jpg attached. I search lilypond documentation and
haven´t found anything like that ( the C3 above the sheet ). Does
someone can help me with that ?

thanks all, Allan
