In bar 11, you see some ghost notes, and semi-articulated notes. This is also a good weapon to have in your arsenal, and this type of dynamic development can spice up a lick or line and make it groovy.
What you have to keep in mind here is that the muting should be done by your right hand only, which entails you playing the line as though the ghost notes (in parentheses) are not muted at all, and then applying a light pressure with your right hand at those particular notes. Not the easiest thing to get down, but work on it slowly. It's really not that different from palm muting when riffing once you get the hang of it. The hard part here is to target individual notes within a line to mute.
