Absolutely correct anatomy in your photo, with the thumbs of each hand facing outward from one another.

However, the illustration has the thumbs of each hand facing inward towards one another.

That cannot be physically correct, unless the person holding it is reaching way over the top of the console while standing in front of it!

Thumbs on each hand need to be reversed to the other side of the hand.

Or, maybe it's just an illusion drawn by M.C. Escher?

pv88, everything is correct.



Thumbs marked with red lines

Just lousy copywork on the part of graphic artist, d00ds.

If person "A" is standing behind the piano, his/her thumbs would have to be facing outwards to hold the bottom of the console:

Yes, or, no?

Extra note:

You have correctly marked the thumbs of each hand, I see.

But both persons are standing on the sides and this is the source of the whole misunderstanding
Left and right, not front and back.

Aha, it does appear as if you are right, depending on how you view it.

The illustration intends to indicate that each person is holding the console from the sides and not the front and back.

It's all about one's perspective then, isn't it?

Thanks for the clarification.

Correct, just like in the photo I posted above.



Indeed, it is all about one's sense of perspective...

And, here is a different bit of perspective:



Now, why am I not getting anywhere?

It seems Piano World has become Anatomy World.

I took a quick read through the NU1 brochure,

http://download.yamaha.com/api/asset/file/?language=sv&site=se.yamaha.com&asset_id=53677

and I see that the NU1 has the new CFX samples!

So CLP 480 VS NU1

NU1
CFX samples
a "real" piano keyboard action
5 years warranty (2 standard + 3 extra years, an Yamaha campaign, at least where I live, right now)

CLP 480
more sounds
more amplifiers
more speakers

Allow me to continue on that thought and add a musical touch
