Great question!   The standard answer would be for you to practice lower level pieces (i.e. level 3 if you’re level 5). And do that every day for about 15 minutes. It will improve as long as you’re consistent and patient.   Try Rhythm books really help if you have a deficiency in rhythmic reading and patterns. I’m the video I’ve showed you an example of one and how to use it.    Let me know if you have any additional questions.   Good luck!   The tortoise always wins, Julian
