chord symbol collides w/music

[Rick Hogg]

I know it has something to do with an \override or something, but how do I reposition chord symbols to not interfere with my music?

\version "2.8.1"

        top-margin = 0.00\cm
        }
% the header
    \header {
        title = "Cherokee"
        tagline = "Learn this in all 12 keys!"
        }
% the music
    melody = \relative c'' {
    \time 4/4
    \clef treble
    \key g \major
