Similarly to Your Grace is Enough the main groove accents all fall exactly on the beat. The up strums add a little movement and allude to the rhythm in the melody. For the chorus you could get rid of the upstrums altogether and add them back in for the verse. Basically more down strums adds more ‘rock’, up strums adds more of a pushed groove which sounds more ‘soul’ey.
If you don’t have a copy of the track handy then try finding it on YouTube or Spotify so you can play along.
I’ve listed this in a box format that shows the song over a single bar in a 16th note format. So the key is to count 1 E & A, 2 E & A, 3 E & A, 4 E & A over the song and crucially KEEP YOUR HAND MOVING at all times. Naturally your hand should strum down on the numbers or beats (1234), the &’s and then the up beats should always link to the E’s and A’s. If you find this difficult to work through on paper then I’d recommend either our Song Learner series DVDs or Intermediate Acoustic DVDs as its much easier to see it on video than in an article.
