Single Staff Spacing

[Chris Trahan]

I'm new to Lilypond. I have a simple score that is short. It's a single staff score. I'm trying to increase the spacing between staves but nothing I try is working.  How do I increase the space between the staves?

A short example is:

\version "2.18.2"

    \new Staff {

         \relative c'' {

          \key g \major

           \time 3/4

           \autoBeamOff

           \partial 4

               c8 d | e2.~ | e2 g,8 b | d4 d b | a8( g)~ g2~ | \break

               g4 e'8 e4 e8 | d2.~| d8 d, a'4 a | g2.~ | g8 c c4 d | e2.~ |

     }

}

Thank,

Chris Trahan
