That finger independence exercise is savage.  My pinky is a lot less independent than I thought.

Thank you for the lessons

Thank u so much, I'm Moh my question is about strumming and picking chords in a song.

Thanks for the great video and useful information! How long would you estimate that one would start to notice the changes after practicing that finger independence exercise for the right hand? finger independence is such a big obstacle, and I've noticed that some people (even non musicians) have a naturally good finger  independence which concerns me that whether this is only the matter of the anatomy, or practising?

How to organize a practice plan to get tremolo picking from 130 bpm 16th notes to 172 bpm  for Dick Dale Misirlou? 1 minute straight for few sets? Something like a gym workout 3X5 ? 😁
