What are these movements?

[casparma]

Cycle the 5 finger parallel set 54321 for the RH descending scale, according to the scheme described in the parallel set exercises. Note that, as you increase the repetition speed, you will need to orient the hand and use a certain amount of thrust or rotation in order to attain the fastest, smooth, and even parallel play.

1, What does it mean to "orient" your hand?

2, What does it mean by "thrust"? Does it mean "push"? but, that is still too vague, for example, in which direction...


please help with these simple problems...

thanks

No one?  why?

No one? why?

Probably because people read the thread, and aren't sure enough themselves to reply :/

 If you ask me, orient sounds like the angle needed in the wrist for the direction your moving, I find it helps me on certain Right Hand runs down a scale. So... basically holding your hand at the piano like you normally would, then pan the wrist to the left.

 I believe the thrust refers to the power needed to play fast and smooth, like it states. Except it's... not tension of course, but instead of the fingers "walking" if you like, you are pushing the hand along to perform the scale. I think they only say thrust here because of the hand being oreinted, elsewise you wouldn't say that... because if you thrusted the hand without the Orientation, presumably your hand would hit the front of the piano (or the panel in front of the keys, whatever it's called!).

Someone please correct me if I'm wrong in these assumptions, but this guy seemed like he needed some sort of answer

I have applied this to one of my pieces, which requires F Major runs, starting from an Upper C down to a Middle C. With the orientation, hitting the B Flat is somewhat easier on the 4th finger And apologies, I'm terrible at explaining, but I tried!

EDIT: You seem to have alot of questions really, some of them appear to be theory, I highly recommend this site: https://www.dolmetsch.com/theoryintro.htm - If you wish to divulge here before hand to see if it holds any answers
 I have actually Emailed the site owner regarding some material on the site (believing it to be wrong, lol), and he was very kind within his reply, and indeed informative! I am therefore led to believe; this site is darn good and reliable!
