Even if you fail, you will not let the knowledgeable audience get out of the show.

"Mr. Li, you have two hours of trial time!"

The consul smiled at Li Wenyin.

"If you have any dissatisfaction with the piano or any adjustments required, please tell me directly!"

Li Wenyin nodded.

Piano trial is the preparatory preparation that must be made for such international piano competitions.

In fact, it looks the same as the piano, but there is actually a gap.

The sizes of vertical pianos and grand pianos are also completely different.

As a high-end grand piano for performers, there will be a size gap.

Five-foot triangle, seven-foot triangle, nine-foot triangle!

It is suitable for completely different occasions.

Small grand pianos are usually used for home use, or auditoriums or small concert halls.

Medium-sized grand pianos are common in various music academies, or in ordinary-scale concert halls and theaters.

Large-scale grand pianos, also known as concert-specific grand pianos, are used in collad theaters, gymnasiums, etc., have very strict indicators and extremely high standards!

And advanced performers can feel the difference in pianos very sensitively.

Small grand pianos have a length of within 1.7 meters, while large grand pianos are basically above 2.4!

Although the width difference on the keys is very subtle, the principle of hitting the string is different. The deeper keys of the grand piano will produce the illusion that they are wider when playing, and will be slightly confused in muscle memory.

Especially for skills such as playing big jumps and octaves, you need to try the piano even more!

Of course, for many performers and high-level piano practitioners, they are used to playing grand pianos, and they can control grand pianos with deeper keys perfectly.

But testing the piano is still essential!

Is it possible for anyone who just came to the competition to be academic and home-based player who is used to upright pianos?

......

After playing the piano, Li Wenyin felt that the touch was quite good.

The rebound strength is moderate and the resistance is also very comfortable.

The pedal is silky and the sound is light.

But Li Wenyin still frowned slightly.

"This piano is a little bit scattered!"

After finding the consul, he frowned slightly and nodded seriously.

After a while, the tuner rushed over with the guys.

After hearing Li Wenyin's narration, the tuner nodded seriously and took out the electronic side sound equipment.

The triangle bracket has been set up long ago, and the dense strings inside are arranged in an orderly manner.

"Here, the three groups of small characters are not correct! The one on the left side should be tuned, and the overtone sounds not right."

Li Wenyin gestured at the master.

The master couldn't help rolling his eyes inside.

The principle of piano pronunciation is to tap the keyboard, then the keyboard controls the hammer and smashes it on the string to make sound.

But 88 keys have more than 88 strings!

In the midrange and treble areas of the piano, each key will hit three thin strings!

In the mid-bass zone, each key is to hit two slightly thick strings wrapped by copper wire!

In the bass area, each key hits a super thick string wrapped in copper wire!

Therefore, tuning the piano is a very cumbersome and complicated matter.

Especially in the treble area, three strings need to be kept at the same frequency so as not to feel discord!

For the same piano, even if the three strings in the high pitch area are actually completely different.

Generally, for household pianos, this double-string triple string is actually installed by folding a string into a U-shaped shape.

Therefore, the sound of running will be easy to hear.

For this top international competition, the pianos are all hand-made and most expensive pianos.

There is a mine at home.

You can fold a string into a U-shaped shape.

But I have to make three different strings for stability and sound quality!

The trouble level can be said to be doubled.

But the sound quality, stability, etc. have also been greatly improved!!

"The string on the far left is too different!"

Li Wenyin complained.

"At least, it's 10 to 15 Hz different from the two next to it!"

“???”

The master looked at Li Wenyin with a suspicious look on his face.

50 Hz is a semitone.

Are you teasing me at 10 to 15 Hz?

Can the ears of that thing be separated?

The master didn't say anything, and put the soundmeter on the wooden board beside the strings in a sceptical manner, and then took out a small wooden hammer.

Tap the three strings that are homophonic.

"Kangbeng! Shet!!"

The master was shocked.

There is a 14 Hz gap!!

Although you know that you who play classical piano can practice your vision, singing, and ears and relative pitch...

But you are so outrageous!!

Although I tapped three strings, the sound made sounds like a sound to people!!

Then you tell me, you heard the three strings in this note, where is the problem with the three strings?

Human?

"Sir, how did you find out?"

The consul also widened his eyes.

This kind of person... hasn't met him before!!

"I'm blind!"

Li Wenyin rolled her eyes and pointed to another string next to her.

"There are also problems with this small word group of so-sounds!"

"This is this...and this is this!"

Li Wenyin pointed out several strings in turn.

"Be careful and adjust it accurately for me! Although you can't hear it, I feel a little uncomfortable!"

"this?"

The tuner's eyebrows twitched.

I just have the idea of ​​giving up.

Li Wenyin shrugged.

"Calling it, I'm not in a hurry, you can take your time!"

The consul covered his forehead.

This is my dereliction of duty.

Although such a small error does not matter at all, it does not even affect the performance...

But if you don’t do the best, you really don’t care enough.

Who would have thought that this guy was a monster?

What else can I do?
