This is what Myriad Music School Piano Teachers call “hovering helicopter practice – finding your hand positions quickly, when your hands need to move over a new position”.
Robert Estrin from Robert@LivingPianos.com says about the same technique –we at Myriad agree.
It’s always a great idea to be over the keys before you need to play them. It will help you relax and be able to concentrate on actually playing and not just where your hands are located. A great way to achieve this is by practicing your music right up until the moment where you need to move your hand. Keep practicing the same line over and over and when you get to the notes you need to play next just move your hand over them but don’t play them yet, just get your hand in position. Keep doing this until your hand effortlessly glides to the correct spot and keep doing it until it just feels natural. When you feel confident you have achieved a fluid and precise movement over the keys, play the notes. Continue to play the phrase and the proceeding notes until you feel confident enough to move on.
You can really do this for all your music – whether it requires crossing your hands or not. The best thing you can do is to stay relaxed and be ready over notes ahead of time. You should never play from a position in which you feel like you are constantly catching up.
