Rather, you should look at this more like
a leaping technique than a finger-crossing
technique. That is, instead of crossing
the thumb under the 3rd finger while the 3rd
finger is anchored on A, in order to reach the
next higher D with the thumb, as soon
as you hit the A with the 3rd finger,
use the 3rd finger to propel the whole hand
into the air so that it flies up the
keyboard and the thumb lands on the higher D.
Thus, whatever "crossing-under" there
is is done in the air with no strain on
the hand, since the air offers no resistance
to movement.
Good advice, Gyro. The main thing with any technique, is that you must allow the hand to go back to its natural form, which is fingers close together with a slight curve, thumb close to the fingers. This must be worked into whatever difficult passages you are doing. By "jumping" rather than trying to do it all by finger work, you will relieve the strain on your thumb.
