The construction of the conference center, because of Zhou Nan's forward-looking idea at the beginning, was built in strict accordance with the anti-echo design of the music center from the beginning of the design.

The auditorium in this hall is set up on three floors, and a large number of silencing devices are used to ensure that the first row at the bottom and the last row at the top can enjoy the pure sound quality without disturbance.

Reverb and echo are the most important configuration in a concert hall, and many concert halls can adjust the timing of reverb and echo with a simple device.

Too short a reverberation time will dry out the sound, and too long will make the music lose its clear lines, both of which are not conducive to music appreciation. Practice has shown that in a concert hall suitable for orchestra playing, the reverberation time should be between 1.5 and 2 seconds.

Of course, the best time to reverb is not the only one, it depends on the listener's preferences, the type of music, the size of the band, and many other factors. For example, listeners who value acoustics want longer reverberation times, and listeners who value musical details want shorter reverberation times.

Symphony can be played in a concert hall with a long reverberation time, while the reverberation time in an opera house must be controlled to less than 2 seconds, otherwise the singer will not be able to hear his voice clearly. Smaller bands want to perform in concert halls with long reverberation times to increase their sound, and too long reverberation times can sometimes be detrimental to larger bands.

Zhou Nan's Bamboo Flute Concerto pays great attention to the length of reverberation, the tone of the bamboo flute is not high, it is long and long, and the requirements for musical details are very high.

For Zhou Nan's one-hour special concert, the organizing committee of the conference center specially added a layer of sound-absorbing cotton on the roof of the conference center using hinges to reduce the reverberation time to less than one second.

Therefore, the 1,400 people who bought tickets and came in enjoyed a high-quality music feast, and even the top and corner audiences did not regret the high ticket prices they spent today.

Zhou Nan's performance was one of the most popular shows at the festival, and the hall, which was supposed to hold only 1,200 people, sold 1,400 tickets because of the large number of ticket buyers.

It's only an hour, but it's 40 Swiss francs, which is almost 10 dollars a ticket. However, Zhou Nan didn't get a penny, and he wasn't alone, he was all the world-class performers who participated in the performance, and they didn't get a penny of remuneration.

The Lucerne Summer Music Festival, from the day of its birth, is not a profitable project, nor does it do any judging, but only provides a platform for all music lovers to communicate.

The organizing committee only bears the round-trip expenses and catering and accommodation expenses of everyone, but the ticket money collected, after removing the cost, is all used to support the development of new musicians and sponsor related music projects.

It's a kind of killing the rich and helping the poor, but everyone volunteers. Celebrity concerts are popular, but many newcomers to music have a problem even eating, and using the income brought by celebrities to help the development of those newcomers can get praise in the industry, so they know that there is no penny of remuneration, but the star performers who are invited have almost no refusal.

In previous years, concerts were almost always run at a loss, because the performance venues were few and scattered, and many newcomers' concerts were held in the open air.

But this year, there are five concert halls at the convention centre, two cinemas and a concert hall in Lucerne's downtown area, and hundreds of star performers are invited to perform special concerts during the month-long festival.

With the venue, there is more money for tickets, and this year, it seems that there is no need for the Lucerne City Hall to allocate any more funds to the organizing committee.

In addition, there are hundreds of folk music groups from all over the world, or recommended music groups, and if the outdoor concert on the lawn is well received, a special music session will be arranged.

Zhou Nan's performance was warmly received, and many people who could not buy tickets strongly requested that a few more special concerts of Zhou Nan be arranged. But the performance schedule is already full, and no matter how popular Zhou Nan is, he can't squeeze out other people's performances.

In the end, under the strong pressure of public opinion, the organizing committee could only negotiate with Zhou Nan to arrange a special concert for Zhou Nan at the end of the festival.

His performance was strongly welcomed, and it also made Zhou Nan a little nervous, and he was almost excited, and he was ready to take Liang Zhu out.

However, Liang Zhu's performance time is nearly half an hour, and just arranging instruments and rehearsing cannot be completed in a short period of time.

After being excited, he quickly calmed down. The influence of this work in the East is definitely greater than that in the West, so it is most appropriate to premiere it in the East in the future.

Moreover, Liang Zhu will be more suitable to play on the violin than on the bamboo flute, but his violin level does not seem to be enough to show off.

However, in this music festival, there are at least ten world-class violinists alone, and sitting in front of Zhou Nan at the moment is a world-renowned violinist.

At the age of five, Oistrikh won first prize in the junior category of Soviet violin performance, and since then has won numerous international awards, giving his first solo recital at the age of sixteen.

After winning first place in the 37 Brussels Violin Competitions with 68 players from 21 countries, he became the most prestigious violin virtuoso in Europe.

Although he is only 39 years old this year, because of his active participation in politics, he has become a representative of the Soviet violin school and has a wide influence in the Soviet Union and even in the world.

He was the leader of the Soviet delegation and dedicated his own concert on the first day of the festival.

Although he loved the violin, he preferred the rich, thick bass, and he always regretted that the violin could not play notes below the open note of the G string.

But Zhou Nan's bamboo flute is one of the best instruments for bass performance, and the bass expressiveness of the bamboo flute, that kind of ethereal distance, is also something that many musical instruments can't express at all, so he is full of interest in bamboo flute.

As the head of the Soviet delegation, he also brought greetings from Comrade Iron Man. With an antique jade flute from the East that was delivered to Comrade Tieren, he also carefully inquired with Zhou Nan about some of the bamboo flute's playing techniques.

The origin of this jade flute is not clear to Zhou Nan, but just by the material of this jade flute, it can already be regarded as extremely valuable.

Zhou Nan rarely receives such valuable gifts, and under normal circumstances, he will not accept them. But this is a gift from the iron man, and Zhou Nan can only accept it without embarrassment.

Although bamboo flutes and jade flutes are both flutes, their expressiveness is slightly different due to the different materials. In front of a group of Soviet musicians, Zhou Nan played a song "The Original Scenery of Hometown".

After listening to this, Oistrich frowned and said: "Although the sound of the jade flute is more accurate in details than that of the bamboo flute, it seems to lack a kind of vicissitudes of ethereal inspiration. ”

Zhou Nan nodded and said, "The voice of the bamboo flute is deeper, and the loose material is more expressive in terms of vibrato." However, the sound of the jade flute is accurate, and the expressiveness of the bass is also more accurate, so it is difficult to distinguish between the two. ”

He shook his head and said, "Personally, I still like the expressiveness of bamboo flute......"

He is a world-class violinist who is a guest, of course Zhou Nan has to ask for advice, and let Audrey, who was listening to it next to him, take out her performance-level violin.

"Mr. Oisstrach, there are many similarities between the timbre of the bamboo flute and the violin, although I have reached a professional level in the performance of the bamboo flute, but in the violin, I still need to learn more. I happen to have this opportunity today, and I hope to get your advice. ”

He laughed and said, "I'll learn bamboo flute with you, you learn violin from me, and we'll learn from each other." You play a song first, and I'll listen to it......"

Caroline put her arm around Ali's shoulders and watched Zhou Nan discuss playing techniques with a world-class maestro with pride in her heart. Zhou Nan's music theory, including violin and piano, was taught by her.

Originally, she thought that with Zhou Nan's talent for super long fingers, his musical talent should be the easiest breakthrough in piano. But the life of exile made Zhou Nan practice in a quiet environment when he was a teenager.

She always believed that Zhou Nan's musical talent had been delayed.

But he didn't expect that the bamboo flute he learned from folk artists in Tianhou Temple when he was a child turned out to be his most expressive skill in music.

This made her a little angry, and she taught him violin and piano, and he behaved very averagely. On the contrary, he couldn't climb the bamboo flute of the elegant hall, but he practiced perfectly.

Doesn't that mean that I can't teach well!

Of course, this was only an occasional thought, and she couldn't ask for more for the way she looked.

Now that she was willing to ask the master for some tips, she was relieved enough.

Audrey was very excited and said excitedly: "Jonas, play Liang Zhu ......"

Zhou Nan smiled at her and nodded.

Audrey's favorite is Liang Zhu's part of the butterfly, and she thinks that the music level of the butterfly part is definitely world-class music.

Even though she is accustomed to Zhou Nan's world-class music, she still believes that Liang Zhu is the highest artistic level in Zhou Nan's "works".

Placing the violin on his collarbone, he clamped the bow to the base of his right thumb and forefinger, and felt the bow flutter gently with the tips of his index finger.

Zhou Nan started playing directly from the superb part of Liang Zhu, and when the music sounded, everyone's faces showed a look of shock, of course, they were not surprised by Zhou Nan's performance level, but shocked by such beautiful music.

They have all neglected Zhou Nan's playing skills and reveled in this beautiful music.

Zhou Nan stopped playing, and Oistrach couldn't wait to open his eyes and stand up. "Jonas, I need you to write me a score now, such beautiful music should be enjoyed by the whole world!"
