It comes up a lot but it is a massive weakness for me, and I wonder if I am just lacking aptitude, or if I'm practicing wrong.
My problem is when I have an alternating bass with the left hand, e.g. alternating chord/note for 8 quavers in the bar, and then the right hand melody is coming in on say "2-and" for some bars, and on "3" for other bars.
My brain wants to either start my right hand with the "chord" or the "note" on the left hand consistently, and I have a nightmare trying to play what the music says. I.e. I want to either always come in on "and" or always "on the beat", but I can't switch bar to bar.
Is this a common problem? What is the best way to tackle it when practicing?
