Not nearly as much as I should. Although I play for a couple of hours most every night, it's not practice. When I find my left hand getting weak from playing the arranger too much and not enough piano. I pull out the Hannon finger excercises and run thru about 10 per night for a couple of weeks, it brings back some strength to the 4th and 5th fingers of the hand ( especially the left hand). I've been well intentioned in my thoughts to work on more piano than arranger but never works out that way. It's just too much fun to play the arranger.
