Techniques for muting strums on an acoustic
What you saw on google and youtube is palm muting and it's different from just muting with your strum hand. A palm mute is when you rest the bottom of your hand(right by the wrist) on the bridge and you essencially "Choke" the sound, prevent it to ring out which gives it a quick bust with a deeper tone. For the Dylan song, he isn't going to be palm muting but he is going to mute with his strum hand. When I play acoustic I mute with my playing hand while strumming so the portion of my hand that mutes is the right side if you hold your hand right in front of you. Now you shouldn't try to just aim for a portion of your hand to mute with, just strum and try to mute while in your strumming motion. This is be more natural than just aiming for a portion of you hand and will allow your to keep time with the music. The other mute is with your playing hand and you can use all, some, or none of your fingers, whichever works best.
