This Étude is really painful for the right hand. Difficulty comes from medius, ring and little fingers playing chromatic scales while thumb and index fingers punctuate.

The thumb cannot be used as a pivot while playing it. After a single execution the muscles are painful, because we are not accustomed to producing legato with only fingers 3, 4, and 5.

Is there a hand position that can help? I have heard that Asians have a different hand morphology that can help them for that piece, is this true?
