The value of proper hand positioning cannot be overestimated. Could you imagine a chef preparing a gourmet meal without a knife? Or a surgeon performing surgery with a dull scalpel?
A pianist’s hands are the tools of their trade. Depending on how well these are “sharpened,” he will amaze you with beauty discovered in Chopin’s compositions, passion pouring from opuses by Bach, power that could only be found in Beethoven’s Sonatas – or… not.
Curves and arches
According to Wikipedia, the catenary arch is regarded as the strongest arch in supporting architectural structures. It is common in cathedrals and in stylistic elements found in Gothic architecture.
The curve is also the key to proper hand positioning. Indeed, sound is produced when the finger touches the key. However, it is the entire body of the pianist that participates in this magical moment. And only a curved structure – the hand in this case – is able to withstand the power which is conducted through a small fingertip to a piano key.
Finding the curve
Searching for the proper curve is surprisingly uncomplicated: our hands are naturally curved when relaxed. And holding a small ball or an apple allows you to observe that natural position whenever a reference or a reminder is needed!
Proper Hand Position
Hand position between notes
Playing the piano has to be comfortable. Thus, the ability for the hand to rest is just as important as producing a beautiful sound.
This picture shows a hand which is completely relaxed, yet ready to be engaged when needed. As you can see, all curves are still there. Another important detail: the fingertips are touching or nearly touching the piano keys. Why not? Rest is rest after all, and a little support from the keys would not hurt!
Two-hand position
Raising a finger
A raised finger has to be curved even more than a playing finger. Think about the tip of a finger being the tip of a spear aiming at the spot on the key which it is about to hit.
