"But...you just refused the invitation from other judges?"

"Hi! Isn't this because I originally wanted to go to Malada!!"

Li Wenyin waved his hand, jumped up from the bed, came to the piano case, and picked up a square blocky object.

"The rosin is almost used up. Anyway, the Canadian rosin is really good. I'll bring some goods to my classmate."

"Damn it?! Use...use it's all done?"

Xu Xinlei was shocked on the spot.

"You used up the rosin?"

"I was shocked!"

Xu Xinlei took the thin slice of rosin from Li Wenyin's hand and was stunned.

"I have seen rosin that I don't use after breaking, and also seen rosin that gets damp or becomes sticky when heated... But this kind of rosin that is used just about nothing... It's the first time I've seen it!!"

A string instrument, or a string instrument, requires friction between the bow and the string, so it is necessary to apply rosin.

Violins, erhus, horse-head fiddles, etc. Although the types of rosin are different, they will actually use similar methods to increase friction.

As modern industry becomes more and more developed, rosin has gradually formed specifications.

But there are still many types of rosin, and different instruments also require different types of rosin.

only......

For almost anyone who has learned this stringing instrument, he can apply a whole piece of rosin to a complete tm.

That's outrageous!!

Normally, you will definitely break it before you use it!!

As we all know, rosin is difficult to use up.

Because almost 55% of the money is lost, and 44.99% of the money is broken.

Only 0.01% is used up...

Even if it didn't break...

How long have you played the piano? The rosin has been fucked by you?

Xu Xinlei vaguely remembered that Li Wenyin’s rosin was given by herself.

It's only half a year?

Such a big piece!!

How much rosin has accompanied the violin majoring in college and is still strong in four years!!

And let alone scratching a hole, you're just wiping it out in all directions...

"Hi!"

Li Wenyin smiled.

"Mainly... I practiced a little ruthlessly in order to prepare for the competition. At that time, I almost used up most of the rosin..."

"so......"

"You just want to go to Canada just to buy a piece of rosin?"

Xu Xinlei was speechless and said to herself that she was a good guy.

"Are you going to be a judge or a purchasing agent?!"

"Isn't this a substitute!"

Li Wenyin smiled.

“…Okay!”

Sister Xu doesn't know how to complain.

Although I was fiddling with the computer, I was still thinking about a question repeatedly.

Such a large piece of rosin...

How did you do it almost run out in half a year?

You don't have pica!

Not supposed, impossible?

???

......

"This time I go to Canada, I have to carefully choose rosin and prepare a few more types. In addition to being used for your own use, I can also send them to my classmates."

Li Wenyin curled her lips and began to plan the types of rosin they wanted to buy.

"Hmm? How many other types? Are there different types of rosin?"

"certainly!"

Li Wenyin nodded very seriously.

"This thing can really affect the sound quality!"

“???Damn it true or false?”

"real......"

Li Wenyin picked up the rosin in her hand and explained to Xu Xinlei.

"Look, the piece of rosin you gave me... is light yellow..."

"What's the problem?"

"Um!"

Li Wenyin glanced at Xu Xinlei.

"This rosin is harder, suitable for pitch violins and humid climates, and is not very sticky..."

"But if it's the north where I often stay, in that dry climate...the dark rosin is actually better..."

"color?"

Xu Xinlei was a little confused.

"I always thought that rosin was different colors just because it looked good..."

"Of course not!"

Li Wenyin smiled.

"The color mainly depends on the season of collection. For example, the rosin in late winter is golden or amber, and the rosin in summer and autumn is dark, and the fineness of the particles is also different. The materials added are different, and the suitable people are also different."

"For example... you have added copper powder, and the powder is not delicate enough. Such rosin is easier to make sound, suitable for beginners... but for performers, it is actually not very suitable..."

"Rosin is a medium attached to the bow scales that increase the friction coefficient with the strings to produce vibration, so the choice mainly requires consideration of the player's own feel and sound quality."

.........

"Then you still use it..."

Xu Xinlei's old face turned red.

When I bought it, I bought it casually at the musical instrument store. How could I notice so many twists and turns?

"Hi! This thing!"

Li Wenyin waved her hand.

"I'm more NB, you can have it, but there is no need..."

"Then why do you want to buy it now?"

"Are you stupid? Why not buy better ones?"

“…I was speechless…”

Xu Xinlei felt that she had gained knowledge and couldn't help but ask curiously.

"You said...copper powder? Is there any other powder?"

"certainly!"

Li Wenyin said.

"Gold powder will be suitable for most string music, the sound quality will be more warm and clear, while lead powder's rosin has a soft texture but is not sticky, and the pronunciation will be gentle and soft, which is more suitable for viola in the mid-range area, or violin playing some mid-bass songs."

"The sound quality of silver powder will be very concentrated and bright, which is more suitable for my style."

"If conditions permit, if you pursue the ultimate performance, it is best to prepare a few bows with different rosin, and choose bows with different rosin when encountering any type of music or specific climatic conditions."

"You can't mix this thing?"

Xu Xinlei scratched her head.
