Thanks Daryl, I will follow your advice and work on loops to improve the tougher parts. I do it sometimes, but I should do it on a regular basis. Patience is not my strong point but everything can learn, but tougher for older monkey.So Marc, if you can hear and feel the rhythm, and simple songs are no problem for you, then (I believe) it's just that you are trying to push yourself too far too quickly (you impatient man you!). What you might try is to take a phrase that is giving you trouble and just play it over and over and over. Slowly, but in the proper rhythm, until your muscle memory takes over. Then move on to the next phrase. And if you have to, break the phrase up into even smaller chunks (but always play the chunks with the proper rhythm).
