Kreutzer 13 is a rather lengthy
étude with only one real difficulty.
That is, of course, the string crossings.
Now, the étude would be easy to play in
many different ways if it were shorter.
But because it's so long,
you must develop the most efficient
technique to play these string crossings.
Otherwise, you will not be able to
Your arm will simply wanna fall off.
So this also builds endurance, as well.
[COUGH] Let's look at how to achieve these
Bares a certain
resemblance to a certain piece for
cello that goes like.
But we'll ignore that for now.
There are two different types of string
crossings we're looking at here.
There's the larger one [COUGH] that's
accomplished with the arm.
And then these small ones.
So the arm takes us from the G string
level to a level between the D and A
The arm must move to accomplish them.
Now, these little and
fast rapid crossings are done with the
The upper arm stays basically in the same
place for those, then it moves back for
the next measure.
So it would be a mistake either to try and
do all this with the wrist.
That's gonna move your wrist into some not
very healthy positions, and you won't get
the clarity of sound.
It would also be a mistake to try and do
it with the arm.
As I've already said, it's gonna wanna
fall off after eight measures.
Or two measures, as the case may be.
So you can start with this one slowly,
But before too long, I'd like you to try
it closer to tempo because
the left hand doesn't have to move too
So it's an easy one to play at a quick
That's gonna force you to find that
efficient way of doing things.
