how do you play a chord where all the strings are used except your D string? is there some way to skip that string while strumming?
Mute the d string

Or play with your fingers
use your the tip of your ring finger, or the one on the g string to mute the d, or lay you rfinger on the a string over the d so it mutes it, dont push down too hard or you ll hear the thud. however if you use just a little muting and mess around youll get it
i enjoy head
If your finger picking, use all 5 of your fingers. If your using a pick, one of your fingers will mute the D string.
dont push the d string down and let what ever finger you use for the A string to mute the D string as well.
