How to use schedule?

Hi,
sorry for the silly question: How to use schedule?
I made this:

function nextTrack()
{
   %NumberOfTracks = redbookGetTrackCount();
   %TrackNumber = CD_TrackList.getSelectedID();
   $trackNumber = CD_TrackList.getSelectedID();

   if (%TrackNumber >= %NumberOfTracks)
      %TrackNumber = 0;

   CD_TrackList.setSelectedRow(%TrackNumber);

   redbookPlay(CD_TrackList.getSelectedID() - 1);
}
function musicman() 
{
if (!$CDPlaying)
   {
      nextTrack();
   }
   schedule(1000, "musicman");
}

I want the schedule function to wait one second and then run the musicman function. How to do this?
