Hi Gianmaria

As far as I know, the most wide-accepted practice is to enclose the music into 
a repeated section ||: :|| and to write how many times it should be played, or 
“ad libitum” if it is to leave to the freedom of the player.

In didactical examples it is appropriate to give some instructions before the 
music pattern. However it’s not uncommon to see staff lines continuing a bit 
past the last bar, maybe with an accompanying “etc.” text.

All these things can be done pretty easily in lilypond, like the following 
example, freely taken from “Rational principles of piano techinque” by Cortot:

\version "2.19.59"

\score {
  \header {
    piece = \markup { "Esercizio n. 1b" \italic "(cominciando col 2° dito - m. 
d. e col 4° - m. s.)" }
  }

  \new Staff \with {
    \remove Time_signature_engraver
    instrumentName = \markup {
      \center-column {
        \line {
          \box "C" "*"
        }
        \line {
          \box "H" \box "R"
        }
      }
    }
  } <<
    \time 2/4
    \new Voice \relative c' {
      \repeat volta 2 {
        d16^2_4 c^1_5 e^3_3 f^4_2 g^5_1 f^4_2 e^3_3 c^1_5 |
      }
      \repeat volta 2 {
        d16 c f e g e f c |
      }
    }
  >>
}

\markup {
  \column {
    \justify {
      *) Esempio tratto dall’esercizio n. 1b (Serie B, capitolo I)
    }
  }
}

\score {
  \new Staff \with {
    \remove Bar_engraver
    \remove Time_signature_engraver
    instrumentName = "ascendendo:"
  } \relative c' {

}




This should help you, I hope.
