What is the concept of playing this minus seven arpeggio at a speed of 140?

One hundred and forty beats per minute, about 2.3 beats per second.

Each hand plays a set of sixteenth notes "4", which is about 9.2 notes per second per hand.

Meter: Touch the key 9 times.

Then the hands are 18 strokes.

Eighteen touches of the keys with both hands in one second don't seem to be exaggerated to the point of being outrageous, and some very powerful children seem to be able to do it.

Indeed, of all the seventh chord arpeggios, the minus seventh chord is the shortest distance between the fourth notes of the chord, and the same goes for moving to the keyboard, and the distance between each key is also the shortest.

Therefore, for children and adults with smaller hands, it is still relatively easy to play.

But if it's just an ordinary minus seventh chord arpeggio, even if it's 140 beats, Qin Jian won't be as sweaty as he is now.

"Octave – minus seventh chord arpeggio. ”

Shen Qingci said so just now.

To put it simply, the requirement to add an octave is to multiply the original 18 touches per second by 2.

Answer: 36 touches.

The main problem is that with the addition of octaves, the difficulty of these two arpeggios simply becomes heaven and earth.

The former is still stuck in the arpeggio technique in the piano children's examination, while the latter goes directly to the octave technique in the later stage of piano performance.

Natsuki Aso didn't dare to blink her eyes as she looked at the pair of big hands covered with green tendons on the piano, and for the first time she found that Qin Jian's hands were completely open and so big.

There was a loud banging of the strings, and there was a buzz in the adjacent piano board.

His wrist moved extremely fast, and every moment he lifted and fell, four notes were struck at the same time.

Four identical scales span four octaves.

But none of them made their presence undetectable, even if they were fast.

Natsuki Aso's heart is extremely shocking.

She knew that Qin Jian's fingers were very powerful, and when she first saw the other party stepping on the weak sound pedal in the video to play the revolution, he knew that this person's fingers were definitely not comparable to herself.

Later, various facts verified that this boy was far stronger than he imagined, but at this moment, Aso Natsuki's three views were refreshed again.

"Pyridine yin~"

An ear-piercing sound breaks the octave rhythm of the chord.

"Stop. ”

Fourteen seconds after Qin Jian started playing, Shen Qingci stopped.

The sound of the piano in the room stopped instantly.

β€œhuβ€”β€”hu————”

Qin Jian held the piano and panted frantically, he felt that his arms were almost out of his body

Shen Qingci's face was also quite complicated, and he admitted that he just wanted to express it, 'minus seven arpeggios', but casually added an octave in front of it.

Recently he was working on a set of arpeggiated scale practice materials for piano learners of all levels, and he was still thinking about how to describe the practice of this technique, and he finally gave up.

But he didn't expect Qin Jian to surprise him early in the morning.

The speed of 140 beats can last for more than ten seconds, and every note is clearly visible.

Shen Qingci's eyes flashed with admiration, and he walked to the piano, seeing that Qin Jian had nothing but sweat.

"Need a break?" he asked.

Qin Jian was stunned for a moment and then raised his head, "No problem, no need to rest." ”

Shen Qingci nodded, "Then let's start with the third movement." ”

Qin Jian said, and finally glanced at the new items he had just obtained in his backpack, and he would study it after class.

Then the space was closed and the third movement of La 3 began.

Like Qin Jian, Natsuki Aso also listened and studied while Qin Jian was in class, and sometimes Shen Qingci would ask her if she understood.

An hour passed quickly.

After the third movement has been completed, Qin Jian's today's lesson is over.

After class, Shen Qingci briefly told the two about the trip to the Tchaikovsky Conservatory in half a month.

The tour is divided into three parts.

The first part is the visit exchange.

In the name of Rachmaninoff's Symposium, the Tchaikovsky Conservatory has invited not only a large number of professional pianists and orchestra conductors, but also teachers and students from the piano and keyboard departments of many top music schools around the world.

It is said that it is an exchange, but in fact, the team of each college holds a concert, and every few years the big guys get together and compare and compare to see whose fist is bigger and whose fist is smaller.

According to the convention, generally the more internationally renowned colleges are eligible to complete one on their own, and the less famous colleges are allowed to complete one together.

"So is our Huayuan a little more famous?" Qin Jian interjected and asked.

Shen Qingci sank, and his expression became serious: "This year, we will have a full concert. ”

Qin Jian blinked his eyes, and he could hear the implication in his words, presumably this time Huaguo Yuan had this treatment because of the return of the other party.

"So for this concert, you both have to be fully prepared. Shen Qingci admonished.

Seeing Xia Shu nodding, Qin Jian also nodded slightly.

However, he knew that Xia Shu was not from Huaguo, so he didn't expect the other party to have any special sense of honor in this matter.

But it does sound like a battle of honor.

"Don't worry, Mr. Shen. ”

Looking at Qin Jian's serious appearance, Shen Qingci raised the corners of his eyebrows, and lit a cigarette with a click.

For a moment, "I have something to worry about, even if you mess up on stage, you are the ones who are embarrassed." ”

"Uh..."

Qin Jian felt that this was indeed the case, and in order to alleviate the embarrassment at this time, "When was the last time such an event was held?"

He digressed and asked, "Where?"

"In 2009 at the Juilliard Conservatory, the last time we talked about it was teaching Gershwin's works. Shen Qing replied

"Gershwin?" Qin Jian said subconsciously, "Jazz theme?"

Shen Qingci nodded, "At that time, all the internationally famous jazz players came. ”

"Tsk. ”

Qin Jian sounded inexplicably cool, "What about the result?

There was a brief silence in the office.

...

This second part of the itinerary is the official theme – a discussion of Rachmaninoff's work.

The last time he was in Haishi, Qin Jian heard Caisong mention that this seminar would not only discuss keyboard works, but also his symphonic works.

Shen Qingci didn't say much about the content of this discussion.

The focus of the piano work is his twenty-four preludes and five piano concertos. ”

Shen Qingci said and his gaze fell on Qin Jian's face.

Pull one, pull two, pull three Qin keys know.

It's just that even in the piano world, there are very few people who mention it.

As for this pull five.

Long.

"Pull five.... Yes?" Qin Jian turned to Natsuki.

Xia Shu also thought for a while with his brows furrowed, and replied to Qin Jian with his eyes seriously.

β€œsimimasanο½žβ€

...

"What's the stop?"
