In his book "Fundamentals of Piano Practice" Chuan C. Chang can't seem to emphasize enough the importance of what he calls the "Thumb Over" movement. According to him, it is a different movement than the more widely known "Thumb Under" movement, that can be used for playing fast scales, arpeggios and runs. Below is a link to a section of his book that has an explanation, complete with video, of this particular motion:

Still according to him, scales and arpeggios must be practiced with both motions, since for most situations "thumb over" is actually better; "thumb under", the more widely used motion, is only suitable and should only be used for slow, legato passages.

What are your thoughts on this, and do you regularly used "thumb under" or "thumb over"?

Thanks a lot,

Marcelo

I'm not 100% conscious of every motion I make 100% of the time but now that you mention it, I do this all the time. Didn't know it had a name!

Any motion (or omission of motion) that reduces friction between the ears and the piano has to be a technically sound choice, IMO. (Although I would never force anything of this sort on a student, if it was unnatural to him or her.)

I must confess .... I can't find the advantage to TO. other than an unbent thumb, (?) what is the difference?

Now, Abbey Whiteside's wrist and shoulder movements I found immediate use for.

Btw, I'm not mocking, I'm genuinely interested in any technical improvements to be made, 'cause that 10/4 Chopin etude is having horrible problems progressing past 144MM.

PJF, do you use your ears to play??? That's a new technique!!!



Just kidding, I think you must mean "friction between THE FINGERS and the piano".

Marcelo

You're working on 10/4?? I'm jealous!

Thumb over seems like it would be very awkward. I'll have to play with it some...

Don't be! "working on" was highly over-optimistic phrase I used there. "playing through once every third day" would probably be more accurate. At least I have it memorized!

As regards TO/U I remember having read something about Lipatti and after a quick search:

Were it even a lapsus calami, it'd disclose a certain exactness of thought.
Everybody should use their ears to play.

More Rosen, eh? I did what everybody (I'm looking at you, Nathan) told me to and ordered The Romantic Generation. It's probably already in but I didn't have time to go by the post office today...

That's the finger. Lipatti is the Moon.



Well done, Terez, you won't be disappointed.

No, I very clearly mean friction between ears and piano. The ear/brain is the first link in the music-making chain, the piano is the last. Believe me; there are many different sorts of friction to be found along the way!

well, as long as you're looking baby, let me put on a show!

In any case, it's a great bk ... definitely a good read and a great reference for years to come! you'll love it

Thank you for your input on this.

So, this "thumb over" thing is really not making sense to me.

This makes sense to me:

When you're not playing legato, there's no need for your thumb to actually cross under your long fingers, because there's no reason for those fingers to still be there when they're done playing the notes. So the whole hand moves across in a relaxed position rather than unnecessary twisting of the hand to pass the thumb under the long fingers.

Is this what "thumb over" means? Because "thumb over" as opposed to "thumb under" seems to imply that the thumb passes over the long fingers. That makes no sense, because it's the same problem as "thumb under", but with added difficulties.

Terez,

When I first read the name "thumb over", I thought exactly the same thing you thought at first, that the thumb would cross OVER and ABOVE the long fingers, but that is not the case.

I thought, "how awkward that must be, worse than trying to play with your ears!!!"

It turns out it is a misnomer, and I think it corresponds to the motion you described when not playing legato.
