Accompany Da Vinci's Super God Day

Early the next morning, Heidi went to Leonardo to discuss the matter.

What she wants to do is a bit cumbersome and needs help.

Da Vinci was spreading jam on the bread at the dining table. Seeing that an old friend came to him, he waved his hand and said, "Would you like some bread?"

"No need, I want to talk to you about one thing." When Heidi saw him, she subconsciously thought of those abandoned city plans and chariot designs.

This is an opportunity to help both of them get more opportunities.

"Mr. Medici will celebrate his birthday on January 1," she said while watching him, "I want to make a gift for him with you."

Da Vinci noticed the quantifier she used, raised his eyebrows and said, "What? A jeweled timekeeping bird?"

"No," Heidi laughed: "Do you still remember the 'player piano' I mentioned to you earlier?"

Da Vinci's eyes lit up instantly.

"I'll get you a pen and paper! Tell me about this thing!"

That kind of thing is mixed with too many memories of her.

Heidi grew up in a wealthy family. After a good education, she devoted herself to the career of film and television performances. In fact, she is not a scientist.

In the era before and after World War II, people were full of prejudice and harsh treatment of women, even if they had real talents, they might not be valued.

In a sense, she felt as frustrated as Da Vinci when she was young.

Heidi is naturally good at observing all kinds of things, and she can think divergently and connect many things together.

She has attracted many celebrities because of her beauty, so she has been able to come into contact with new things in many fields.

During World War II, a typical problem was the frequency band of the first signal——

The wireless frequency band itself is fixed. Once the signal is intercepted, the submarine can flexibly dodge and cause greater losses.

Due to the advanced signal interception system, the German army has won many battles and victories. The flames of war are everywhere, and people live in fear and despair.

At that time, Heidi was only 25 years old and did not have any military experience.

But she felt at the time that she should do something.

And so it really did.

The principle of this matter is very simple -

As long as the wireless communication technology can be used to allow the launch boat to be controlled more flexibly, it can gain an advantage in war.

The premise is that the enemy will not find this communication frequency band, and intercept or even cut it off.

Her first thought was the remote control.

The remote control of that era had just been invented, and as long as the round dial was turned, the channel of TV and radio programs could be changed.

If a piece of information is broadcast in sections on different channels, even if the enemy can intercept a small part of it, it will not affect the overall situation.

— This is not a well-executed idea.

It was also at that time that she met an excellent American composer at a friend's party.

The man played the jazz piano superbly, and he had an extraordinary conversation and quick thinking.

What's more, his younger brother died due to the German army.

—George Antair.

So Heidi wrote her phone number on his windshield with lipstick.

They jointly produced three inventions, drew a large number of drawings and wrote detailed and clear description documents without any engineering foundation.

The core component of this is the player piano.

As long as different holes are printed on the paper roll, so that the roll can be pushed and rotated by the bellows, the piano seems to be played by invisible fingers, and has coordination and resonance far greater than ten fingers.

If the launching boat and the boss have two identical piano miniature reels and start playing the pre-recorded information of the paper reel at the same time, they can achieve frequency hopping communication in 88 frequency bands——

Just as the black and white keys are pressed in different parts, the communication keeps jumping around in different frequency bands.

The relevant documents and ideas were eventually adopted by the American Institute of Inventors and forwarded to Caltech.

The professors created electronic devices based on these ideas and applied for a full patent for the entire technology.

But many years later, Heidi was accused by reporters of being a female spy who used her beauty to steal industry secrets.

——The reason was that her first husband was an arms dealer from Austria.

After all, they refused to believe that such a great design was actually related to a woman.

The media is naturally entangled, eager to dig out some dark insider like a hyena.

When she was interviewed for the last time, her tone was quite indifferent.

"I know what I did."

"I don't care what other people say."

Thinking of this, Heidi's pen tip paused.

Even after many years, when she recounted the operation principle of the piano roll again, her thinking was still smooth and clear.

Different parts and linkage structures are drawn with intuitive sketches. Although there are some grammatical and spelling mistakes in the Italian annotations, it is enough for people to understand these things further.

When she picked up the pen, she suddenly felt much calmer in her heart.

If it can be created again, it will be the mechanical design that makes the world exist.

It's more than just a flattering gift.

It is the key to knocking on the door of ideals.

Medicine, engineering, military, economics—

She has more power to speak, so as to transform Florence into a more stable and secure existence.

After the problem of survival is completely solved, then consider going to other countries for vacation and relaxation.

As long as the problem between Italy and France is not resolved, she will not be able to relax her vigilance.

The most amazing thing about Leonardo da Vinci is his unparalleled comprehension and associative ability.

Even if part of the explanatory text was grammatically confusing, he could roughly understand the overall idea after a few glances.

"You mean, we use one piano to make paper rolls, and then let the paper rolls control the keys on another piano?"

Heidi nodded in response, lowered her head and marked another paragraph of text.

"The first thing to make is the strumming device."

Medieval pianos were divided into two types, one was clacked and the other was plucked.

The clavichords of this era have heavy keystrokes but weak treble, which is indeed not as pleasant as those of later generations.

The roll itself will be divided into dozens of columns, each with different holes.

Wind passing through those gaps triggers the air valves, which drive the corresponding wooden fingers to strike the strings.

As long as this device can be done well, the follow-up will not be a problem.

Da Vinci chatted with her for about two hours, and then closed the door with a stack of drawings.

"Come back to you later—I'll think about it first!"

Then this farewell disappeared for nearly ten days.

Heidi understood this quite well.

After all, to do this thing, not only must you have a good understanding of the mechanical structure of the piano, but you must also understand how to design the air valve.

She only needs to bring forward the core ideas, and the rest is up to nature.

On the other side, Lorenzo looked at the bill brought by his subordinates, his brows were tightly furrowed and he didn't speak for a long time.

He originally thought that the girl's idea was a bit absurd, but he still sent someone to check it out.

According to his previous understanding, as a banking family, the Medici should have a mature and reassuring operating system, and occasionally poor management is not a big deal.

The information that Kexima gathered from several other investigators... was very irascible.

He was an ordinary property manager that day. Not only did he fill his own pockets, but he also secretly transferred many properties under his own name.

Vaffanculo!

That bastard!

As the heir to a huge amount of wealth, he is busy with official duties on weekdays, and he has no time to liquidate hundreds of real estate investments and movable funds one by one, let alone those huge and complicated businesses.

These things were originally handed over to someone he trusted, or an old buddy arranged by his grandfather.

But the facts have proved that if this loophole is discovered later, the foundation of such a huge industry may be hollowed out by moths.

He resisted the urge to smash things, and his anger was constantly restrained by reason.

"—Vaffanculo!!"

Keshima pretended not to hear anything.

Lord Lord, it has been a long time since he cursed anyone, and this time the matter is really hard to deal with.

So before some people had a fulfilling and relaxing Christmas, they were all brought to court.

The indictment that should be sued, the indictment that should be indicted, one--one should not be let go!

Those who can solve the problem with justice will directly sue for bankruptcy, and get back the property that should be compensated with interest.

If it cannot be resolved by the judiciary, it can only be resolved by private law.

This incident was so loud that it alarmed many people inside and outside the city.

——The poor management of the Medici family is actually an internal problem? !

——I heard that several principal criminals went directly to the gallows!

—This is blasphemy against God!He deserves to go to the [-]th floor of hell!

Some were flogged, others were taken from their newly purchased estates and farms, and others spent the rest of their lives in prison.

Various rumors and news also began to ferment, but it was as if bells were ringing in the surrounding city-states.

Not only many people in the banking industry have become cautious and responsible, but many potential customers who intend to cooperate have finally breathed a sigh of relief.

Looks like it's finally being fixed.

Overnight, all kinds of managers from inside to outside began to accept investigations and assessments.

Lorenzo didn't ask Heidi to participate in this matter, but as long as it was something he personally handled, he would always do it to the extreme.

In recent years, his main work has been on signing treaties and establishing alliances, and he really did not take into account the operating conditions of the family business.

——However, the lord who can manage the relations of more than a dozen city-states will not know how to handle the old business of the family?

As a result, dozens of unqualified managers, large and small, were kicked out, and even the banks opened by many Medicis from abroad were completely renewed, with much higher efficiency.

Although Lorenzo did not ask Heidi for his opinion, the latter submitted a reference document in a timely manner.

It talks about the performance appraisal system, the year-end report system, and the quarterly review system that is useful enough.

With just a few strokes, he directly built a sufficiently stable structure that allowed him to manage the most affairs in the shortest time.

The lord accepted the suggestion silently, and then ordered his subordinates to write a new file.

Things are starting to change in Florence.

-2-

It wasn't until Christmas began that Da Vinci finally reappeared.

He knocked on Heidi's door with a square box, and he felt elated.

"I made the air valve—and also worked out that recording piano you mentioned."

Heidi moved away from the door in surprise, watching him go in and put down a lot of things by the table.

Da Vinci originally wanted to discuss with her after making the air valve, but unexpectedly, he was fascinated by it as soon as he started it, and even started to complete various subsequent processes involuntarily.

When he came back to his senses, he had successfully made three copies of the paper rolls for performance, and he was sitting by the piano listening to the song.

Heidi helped him unwrap the long paper tape, and subconsciously gave a sigh of admiration.

He really is a genius.

These things were actually born after 1910, and there are many abstract designs in them.

But Da Vinci really made clear enough mechanical drawings, and asked the craftsmen to copy them.

If her thoughts were the long train, his presence was like the boiler and the charcoal fire, allowing all thoughts to shuttle away, creating profound tracks out of thin air.

The first roll was completely blank as a comparison sample.

The second is the roll of recording paper that needs to be placed on the windpipe of a special recording piano.

When the player presses the keys, the strings drive the air valves, which in turn trigger the small hammers.

There are small pits of different shades on the long paper tape, which are the marks left by the small hammer.

He even made a hole puncher, which only takes 10 minutes to complete a song.

Heidi looked at the linkage device in the box and vaguely understood it.

Compared with Da Vinci's physical installation, her design concept draft has a very different difference.

Medieval pianos did not have standing cabinets, nor could the automatic playing device be placed above the score.

Da Vinci made a strumming mechanism directly behind the body, also equipped with a bellows.

"So... are you planning to let someone lie on the piano to press the bellows?" Heidi looked at the delicate gears and air valves, then turned to look at him and said, "Or do you have other ideas?"

"Clockwork." Da Vinci smiled and said, "I found inspiration from Giotto's clock tower and the clockmaker."

Heidi was stunned for a moment, but also laughed dumbly: "Good idea."

They went to the recital hall near the Palais Ducale and conducted an experiment next to the piano.

It was exactly as she expected——

The plucked string device was blowing out the roll of paper above the strings, while the keys in front of it fluctuated smoothly as if being pressed by an invisible hand, and the sound of the music was smooth and pleasant.

Heidi could vaguely imagine this kind of picture——

Leonardo probably hasn't slept in the past ten days. After finishing the air valve and the music score, he even lay down next to the piano for a whole day.

He is pure in heart and always has a kind of attachment to things.

Just like when I was young.

"I always feel that these tunes are too tacky." Da Vinci took off the paper roll, looked at her and said, "Mr. Medici may have heard it many times-what is there in the Holy Roman Empire?" Is it a tune?"

He has exhausted too much energy recently, instead of writing a new song temporarily, he just wants to have a good sleep.

Heidi suddenly thought of something, and motioned him to put the paper tape for 'recording' on the designated position.

After Da Vinci indicated that she was ready, she took a deep breath and began to play an ancient tune.

The song was supposed to appear 200 years later and was hailed as Austria's second national anthem.

Since the strings were blocked by the paper, they didn't make much sound at the moment, only a vague and dull sound.

Heidi played at a leisurely pace, but her expression was gentle and nostalgic.

What she played was "The Blue Danube" from her hometown.

You are sentimental, you are young, you are beautiful, you are good-natured, and you shine like gold in a mine.

There the truth awakens, beside the Danube, the beautiful blue Danube.

At that time, the Austrian Empire suffered a disastrous defeat in the Austro-Prussian War, and the people of Vienna were depressed and bored.

But this song is like a soothing and warm spring breeze, which can awaken many long-sleeping feelings.

A hundred years later, it's a New Year's Eve repertoire.

When midnight passes, this waltz will be played in Vienna's Golden Hall.

It is so cheerful and gentle, as if it can melt the snow in everyone's heart.

Heidi recalled many pictures from the past, and suddenly remembered this wonderful coincidence.

After midnight, it is the first day of the new year.

It also happened to be Mr. Lorenzo de' Medici's birthday.

——This time difference has traveled through a hundred years, but it is so appropriate.

After she finished playing, Da Vinci took off the paper roll and began to punch holes on the spot.

Heidi went back to Ducale Palace, brought him some cheese and fruit like afternoon tea, and poured him a glass of wine.

Da Vinci put back the paper scroll like a password scroll, wound up the clockwork, and raised his glass to her.

In the next second, a beautiful and soothing melody flowed out.

Heidi was leaning against the piano, listening a little ecstatically.

She did not expect that after a long old age, she would have such a new life.

Medicine, chemistry, art, and music.

She wandered in the noisy and ancient city of Florence, bringing strange and brand-new medicines to people, and even listening to the music 200 years later with a morning star in history.

This is not the renaissance of her old soul.

The word Renaissance means resurrection.

Such vocabulary was used by historians of later generations to summarize this era, endowed with a sufficiently appropriate extended meaning.

Resurrect, in such a corrupt and dark world.

The year 1480 has finally arrived.

The lord of Florence ushered in his 31st birthday, and grand balls and celebrations were held in the court.

Not only the aristocrats and artists in the city attended the meeting on time, but also many dignitaries from foreign countries also came in carriages to present him with generous gifts.

Heidi and Da Vinci presented the automatic playing device together and saluted neatly together.

When the guests saw the strange ironware they presented, some of them laughed disdainfully.

But according to Da Vinci's explanation, the attendant moved the clumsy and weird guy to the piano, and set up the position carefully.

The clockwork was wound up, and there was no one in front of the piano bench.

In the next second, there are black and white piano keys pressing down and bouncing, and the paper roll behind is getting longer and longer.

People finally showed a look of surprise.

Some of them are because they have never heard such a tune, and some are surprised that such a machine can make music unplayable.

This was not caused by ghosts, nor was it that a witch was casting spells in front of everyone.

The long paper roll kept coming and going, and the mechanical fingers struck the strings. The melody was so pleasant that the whole hall fell silent, occasionally mixed with exclamations from a few young people.

Lorenzo had just recovered from another gout bout for a few days, and still had slight pain in his knees and toes.

When he heard the smooth sound of the piano like a winding river, he looked up at the girl in the turquoise dress.

Her long hair hangs down her shoulders, her long eyebrows are like two crescent moons, and there is a smile in her light blue eyes. Her whole person is so beautiful that it is not real.

The singing that he heard faintly when he fell asleep that day seemed to be awakened in his mind again.

Hedwig Eva Maria Keesler.

Lorenzo looked away, and reached for the glass of wine beside him.

At this moment, he actually wanted to ask her some questions.

After preparing such a thoughtful gift, what kind of reward do you want?

Why did you mention...leaving Florence?

As if thinking of some advice, his movements suddenly paused, then stopped and retracted.

It doesn't matter if you don't drink it.

This public performance really earned enough gimmicks.

On the one hand, the tune was indeed extremely beautiful, not only the nobles in Florence had never heard such a melody, even the foreigners who came to celebrate were fresh.

On the other hand, it is the whole set of machinery that is amazing enough.

Before the music was finished, someone was eager to make an appointment with Leonardo Da Vinci, asking him to tailor such a piano for his own family, and the price was negotiable.

Because of this, Da Vinci was completely surrounded in the second half of the banquet.

Heidi danced several dances with her friends and laughed quite easily.

Botticelli's complexion improved a lot. I think he put down a lot of things and started to look forward.

Mr. Alessio also came to say goodbye, and I heard that he was going to take up a new job in the outer suburbs.

They danced with her, in unison admiring the way she looked tonight.

Such a young and beautiful face is really a gift from God.

The lord is really starting to quit drinking.

He consciously uses less, occasionally substituting orange juice for wine.

Beer has disappeared from the office, and red meat is far less on the dinner table.

He began to regularly control the intake of shellfish, and basically did not touch anchovies.

Lorenzo has lived a highly self-disciplined life since he was a child, and it doesn't seem to be very troublesome to adapt to these strange requirements now.

His health is indeed getting better gradually, and the frequency of gout attacks is gradually decreasing.

At the same time, a piano was added to the lord's bedroom.

When he is asleep, the sound of the piano will also flow out, like the quiet and winding blue Danube.

The author has something to say:

【January 2, manuscript deposit notes】

Source: unknown

The origin of automatic playing piano can be traced back to Europe at the end of the 19th century.At first, people tried to add a movable "player" (pyer) in front of the ordinary piano, which looked like a small harmonium.

A row of 65-88 "wooden fingers" are placed above the ordinary piano keyboard, replacing the pianist's hands.The musical instrument uses a perforated paper roll (the position of the punched hole is consistent with the piano score) to record the score, uses the pedal bellows as the power, and slowly rotates through the paper roll, and the hole position on the paper roll is linked with the driving mechanism. Fingers" hit the keys to play music.Since then, designers have installed the attached musical instruments directly inside the piano, and can also control the speed, strength, pedals, etc.

This type of automatic piano was widely popular in home entertainment in Europe in the 20s, and there was a record of producing 20 units within two years; it was gradually eliminated in the 50s due to the rise of radios and record players.

Since the number of punched paper rolls is not limited by the ten fingers of the human hand, the scale and range on the piano can be used as much as possible, so the automatic piano is still favored by innovative modern composers.Rachmaninoff, Debussy, Mahler, Gershwin, and Richard Strauss all wrote music for this instrument, and made paper tapes for automatic piano performance.

The pipeline of this automatic player is old and cannot be used. After repairing, it should still work. Paper tapes can be purchased abroad.

This Milton piano has a complete steel plate that is almost exactly the same as a modern piano. The strings are also not too old for a cable-stayed piano. The strings and other parts are well preserved and have not been refurbished and replaced. Due to the multi-piston and camshaft automatic playing of the engine, the original pedal is used as the driving force in use, and the pedal needs to be taken out to inflate before it can play automatically.

His cultural activities caused him to neglect the affairs of his merchant houses far and wide.His agents took advantage of his single-mindedness, wasted and defrauded.He gradually withdrew property from business and invested in urban real estate and large-scale agriculture, saving the family fortune.He enjoyed tending the farm and orchard himself, and was as familiar with fertilizers as he was with philosophy.Thanks to scientific irrigation and fertilization, the land near the villas of Garic and Gaiano became a model of agricultural economy.
