The Musicopia Justin Guitar Android app has it’s limitations.
You are right. It provides a simplified strumming pattern as opposed the the more complex pattern that Justin discusses in his Wonderwall video. Honestly, someone who is just learning Wonderwall should probably focus on the chords and chord changes until they are down pat - then, work on the more complex strumming pattern.
Baby steps…
I’m just starting practice for Grade 2, Module 9, 16th note strumming patterns. At this point should I be trying to tap my foot on each beat while practicing the three different 16th note strumming patterns, or should I just be concentrating on keeping my strumming hand moving uniformly? I find trying to keep 4 beats to the bar with my foot messes with my strumming pattern, but I don’t want to create a bad habit of not keeping the beat with my foot (i.e. practice makes permanent)
IMHO, it’s more important to get your strumming hand (and wrist) moving uniformly to a metronome. Adding in the foot tapping on the 1 - 2 - 3 - 4 while the hand & wrist are moving to 1e&a2e&a3e&a4e&a is a secondary, but important goal for the long term.
I’ve been learning for ~4.5 years now, and I still find it difficult to tap my foot while simultaneously working on a new skill. Once I have the skill under my fingers a bit, it’s easier to add in the foot-tapping. The brain can only focus on one thing at a time.
YMMV
I very much appreciate the input!
