How to practice this simple progression?

[casparma]

For a C scale, except that you play 'b flat' instead of 'b', ie

c, d, e, f, g, a, b(flat), c, d, e, f, g, a, b(flat), c, d, e, ....

and by fingering (right hand), 1 2 3 1 2 3 4 1 2 3 1 2 3 4 ... respectively

I have a difficulty moving my 1st finger under my 4th in the transition between b(flat) and c...

the movement is awkward and arduous. Although it's not the case for b and instead of b(flat) for me.

I simply make a sudden jump instead of actually moving my thumb and going under my 4th like what I do in normal C scale. You can in fact here there is a tiny little break....


Can any one tell me a way to overcome this?

thx

Are you working on Chopin prelude in D minor. Its acctually a very nice scale, you might need someone to demonstrate haw to play this at the piano.Sorry

THANKS any way....

I was in winter holiday so I could not aproach my teacher.

You may not have realized it, but you are playing the F major scale (starting on C makes it C-mixolydian scale).  The standard fingering for this is what you are doing, and I would suggest you simply work out the physical issues with your teacher.

However, as always seems to be the case with piano, you don't have to follow strict rules and are free to finger passages however you want in order to acheive the same results.  Don't hesitate to try 1234123 instead, since you said you are able to cross under smoothly from a white key to another.

You have tried these two ways as far as i can tell:
1) Trying to move the thumb under the hand moving mostly the thumb alone and not moving the rest of the hand (this is a very big stretch for the thumb try doing it at the computer desk: place the tips of fingers 2 3 4 5 on the table and see how far you can move the thumb under the rest of the hand, you will struggle to get it as far as the 5th finger or beyond and this is what you've having to do to make that extreme thumbunder motion.
2) simply moving the hand quickly: this is fine for staccato passages, detatched passages, or very fast passages, but if you want a nice legato you can't use this motion in such an extreme purity as simply moving your hand quickly to the right.

what you need to do is find a place between these two extremes. when doing the thumb under method before, try pivotting the hand about the 4th finger on the Bb note a little so that it brings the thumb closer to the C note without actually moving the thumb anywhere at all, then all you need is a small thumb motion, and a little wrist motion to get it to the C. you will have to experiment a little to find what works for you best.

try looking at this post: https://www.pianostreet.com/smf/index.php/topic,1918.msg15015.html#msg15015 it goes into more detail of describing more motions of playing similar things.
