Here’s a great way to practice different strumming patterns and learn a song at the same time.
If you have either of Justin’s Beginner Songbooks pick a song you want to learn. The strumming pattern is written there for you. Next set your metronome to the correct bpm. If you have Volume II the bpm is there for you top left corner. For Book I you’ll have to search out the bpm on the inter webs.
When you get to the strumming part of your practice routine you’re all set. Turn on the metronome and go.
If you have the songs app you can then do the same thing when you get the that part of your practice routine. Having the metronome running at the correct bpm is a big help.
I’ve found it’s great for learning new strumming patterns.
Anyway - I hope that helps someone. It’s pretty straight forward but it took me until today to apply it to my practice.
