英译汉并保留换行符：Another tricky section is bar number four.
We have octaves in the left hand and broken octaves in the right hand.
So what I like to do here is to practice my left hand octave separately.
I practice the thumb only.
I practice my fifth and fourth finger only, so upper voice and lower voice of the octaves.
I do the same in my right hand and then I focus on with my eyes on following the two thumbs.
So to not go like that, but that is actually the main rule for octaves is to follow the inner voices, the thumbs and let the outer fingers do their own thing.
They will follow automatically, basically.
The next exercise that I do is I practice in the same sections only.
I practice one section slowly and one section fast.
So we have four slow notes and four fast notes and I alternate that without taking any breaks.
So I will start out with four fast notes leading up to the first beat and then from the first beat I have four slow notes and then the next group is going to be four fast notes, the next group four slow notes and so on.
And what this exercise does, it challenges you a bit more compared to the sections because you don't have that break where you can just bounce off the note and relax and take your time.
You have to keep going, but you have a break, so to speak, because you have the four slow notes coming in.
So that is a very effective exercise in my opinion.
And once I go through the entire passage, I then turn it around and if I start it with four fast notes, I will now start with four slow notes, so that each note has gone through every possibility.
The next thing that I do is I practice the left hand separately and I'm saying left hand, but I actually mean left and right, basically the accompanying hand.
So let's say the easier hand.
This is so, so important because yes, the hand is not that challenging.
We only have a couple of staccato thirds and some chords, but still you have to make sure that that hand is completely secure, that you can play blindly, that it doesn't take anything away from your focus when you then add in the very challenging, technically demanding right hand or left hand, depending on the bar that we're playing.
So I really make sure that my accompanying hand is very secure, that there is no thought that I have to waste on it when I put both hands together.
The next exercise that I do is I practice the passage in half bar sections.
So basically now the sections are doubling in length compared to the sections that we had before.
And the other difference is I'm not just playing the one hand, but I'm putting both hands together.
So this really makes it feel different because you suddenly have the accompaniment in there as well.
But I find it important to include the accompaniment so that you already get a feeling of what it's going to be like when you're playing through it.
Now, if this doesn't feel quite right to you just yet, I would suggest that you start out by playing those half bar sections in the right and left hand only in the hand that has the fast notes.
And then do the same thing by adding the other hand in as well.
So just take one step in between.
But I do find it important that you do practice it with both hands in those sections already.
And if you need it to be a little bit slower, that's totally fine.
Then you do it a little bit slower.
Keep in mind the important thing is doing the exercises.
The speed is not what's important.
You can start at the slowest tempo that you can imagine and then gradually increase.
Because by repeating those exercises, you will be able to increase the speed eventually.
And once you've gotten to that point, you can basically just make the sections larger and larger and larger.
So you can do, we just did half bar sections.
You can do one bar sections, two bar sections.
And once you've gotten to two bar sections, you can start playing through it.
Now, just one quick comment again about the tempo.
When I learned it, I used to have a different tempo for the little tiny section that I talked about in the beginning, the four notes.
A different tempo for half bar, a different tempo for a bar, a different tempo for two bar.
Because my teacher really said it's good to start out with all of these exercises early and better start out at the slower tempo.
So yes, my two bar sections were very slow compared to my tiny four sixteenth note section, but I was practicing them.
So bear in mind that it's possible to have different tempi in the different exercises.
The important thing is just that you do them.
And don't expect too much too quickly.
My experience with these studies has been that it takes a long time, but it's very, very rewarding.
Because if you let it develop over time, because if you let it develop over time, you will develop a very secure feeling in playing them.
And it will improve your technique a lot and you will develop confidence in being able to play them at the end.
