Some viewers have said, ” I have a problem that my left hand plays as loudly as my right hand. Could you please tell me how to control my left hand’s strength?”
Here’s one of my answers:
Bring your mom’s/your kitchen scales next to your piano. Using your RH, press on the scales until it goes as far down as it can (maybe to 1kg or 1.5kg). Using your LH, press it down lightly…maybe to 300g. Now, at the piano, play each hand with the same amount of force and listen to how loud it sounds. To make a loud sound, you need to “push” the keys in FASTER. For softer sounds, you relax when pressing the keys. The trick is to do this at the same time in a different hand.
Then practise a simple exercise first, separate hands, then together eg. C D E F G F E D C, visualising RH pushing the keys further in than LH for EVERY NOTE. Most people can do the first note, then they forget the others. Play slowly and carefully, making every RH note much louder than LH. If you practise like this every day, you’ll soon learn how to control the tone in your hands independently.
