Strumming Opens and Mutes – Exercise One
When indicating changes over time, we use symbols above a line of rhythm [or words, melody]. For the following exercises, we are using the Open Chord [O] and Mute [M], and writing those symbols [O and M] above the rhythm.
Synchronize the mute to the down strum on the change. Mute it at exactly the same time that you strum down. And, release to the open exactly on the down strum.
