Best Strumming Lesson
I like to think of strumming patterns as tools. Like any woodworker will tell you, the more tools you have the more things you can create. This same idea carries over to guitar with strumming patterns. The more you have in your “toolbox” the more things (songs) you can create.
Even just by learning these you’re actually building a better rhythmic foundation. And anything that will make you a better guitarist is worth learning!
