This song uses a unique expression technique to express the majestic, deep, solemn and noble charm of the mountains in the alpine part. The second half of the flowing water part vividly expresses the artistic conception of the murmuring water and the majestic mountains. The flowing water changes in nature, there are the murmuring of small streams, the majestic east of the big river, the rushing of the inclined waterfall, and several clear and transparent overtones, which remind people of the scene of the splashing of the mountain spring Ding Dong. The whole song is grandiose and profound, showing a beautiful and soft Jiangnan mood.

Abu, who doesn't often appreciate guqin music, was deeply moved by Yelu Ziye's piano skills. He closed his eyes and quietly listened to the beautiful sound of Yelu Ziye, and the guitar made by Lu Xiaoyu in his hand unconsciously played to echo Yelu Ziye's music.

Speaking of this guitar, it can be regarded as Abu to learn and sell, when Lu Xiaoyu was still in the Flying Tiger Army, he invented a lot of things that seemed unbelievable in the era of Nanchu, such as explosives, cloth armor, etc., but Lu Xiaoyu not only made achievements in military equipment, but also was a person who pursued high quality in art, so that when he was bored, he often taught everyone to sing the military song "What is the difference between us soldiers and soldiers......".

Later, he realized that singing alone was not enough, so he "invented" the guitar. After having a guitar, the Flying Tiger Army did not become so boring in his spare time, but everyone followed Lu Xiaoyu to learn folk songs together, singing those easy-to-understand lyrics, and it seemed that the whole person was relaxed. It was at that time that Yingbu became a hobby of singing and playing the guitar.

Lu Xiaoyu himself is not a person who sings very well, and even has some incomplete five notes, but he still dares to sing in front of everyone. The soldiers of the Flying Tiger Army clapped their hands "against their will" after listening to the singing of a superstar every time they listened to it. When he heard that Yingbu wanted to learn to sing and play the guitar with him, Lu Xiaoyu originally thought that he was just saying it casually, but after listening to Yingbu learn to sing the songs he sang, he was instantly impressed with him. If Yingbu were to be brought to modern times, he would definitely be a big star in singing. The song that was originally out of tune was rejuvenated with a beautiful melody under his interpretation. After listening to the song sung by Abu, everyone knew that the song Lu Xiaoyu sang before could be so good.

Lu Xiaoyu then taught Yingbu how to play the guitar, he learned very quickly, and he could play and sing by himself in a few months.

The guitar is also known as the six-stringed instrument. The top and back are flat, the waist is generally concave without horns, and the classical guitar is generally not recessed. The neck is wide and long, with string rests on the fretboard and a number of narrow, slightly upwardly raised metal grids called "frets", which divide the strings into many semitones.

As a member of the family of stringed instruments, the guitar is a stringed instrument that produces sound by plucking the strings on top of it. The strings are plucked with one hand and the fingers of the other hand are resting on the fretboard, which is a small strip of metal that covers the neck. The sound of the strumming is enhanced by the guitar's resonance box.

Lu Xiaoyu taught Yingbu the guitar playing techniques he had learned, such as glissando, string pinching, hooking, pointing, pushing, kneading, plucking, and playing strings. Yingbu is really a genius in learning music, and he quickly practiced the guitar well.

Because of its elegant timbre, easy to learn, the guitar has a very individual timbre and expression, which can not only express the euphemistic and moving murmur, but also express the majestic heroic spirit, so that many people are haunted by their dreams; A hollow acoustic guitar, plucked the six golden strings, can be filled with a youthful light melody, play a soothing musical space, can express joy, anger and sorrow, can also cultivate a solemn and elegant temperament charm, beautiful timbre and chic playing can add its personal charm.

In terms of performance, the guitar has a beautiful tone and rich expressiveness, and can play pieces from various musical periods, including solo, ensemble, concerto and accompaniment. Compared to the piano, the performance of the guitar is even better. The only thing is that the volume of the guitar is not as small as that of the piano, but for modern people living in densely populated environments, the low volume of the instrument will not disturb the people during practice, so there are more choices in the practice time. It is one of the main instruments of today's pop music and enjoys the reputation of the "Prince of Musical Instruments". The classical guitar, along with the violin and piano, is one of the world's three most famous musical instruments. Therefore, it is also very popular in the barracks, and Abu Da can sit alone on the hill in the dead of night and play the guitar and hum his own songs.

Yelu Ziye thought that he was already very good at the piano, but he did not expect Abu to play a tune that was refreshing to him. Different from the ancient music of alpine and flowing water, it makes full use of fingering techniques such as "overtones, rolling, whisking, squeezing, notes, up, and down", depicting various dynamics of flowing water, and expressing the meaning of aiming for flowing water and the wise man enjoying water.

First paragraph: Introductory part. The melody is constantly jumping and changing the pitch in a wide vocal range, and the faint finger shift and the real tone are alternated, and the melody is hidden and appearing. I still see the top of the high mountain, the clouds and mist are shrouded and uncertain.

The second and third sections: clear overtones, lively rhythms, like "the murmuring and the cold current; Clear and cold, the trickle of pine roots. "Listen quietly, and the feeling of pleasure arises spontaneously. The third segment is a repetition of an octave of the second segment, which omits the tail of the second segment.

The fourth and fifth paragraphs: like the melody of the song, "its rhyme is melodious, like flowing water." ”

Sixth section: First of all, the melody rises and falls, and the large upward and downward movements. Then the continuous "rolling, slow whisking" as the sound of running water, and above it played a rising and descending tone, the two cleverly combined, really like "the extremely boiling and surging view, with the image of the dragon's roar." Listen quietly, as if sitting on a dangerous boat across the Wu Gorge, dizzy, thrilling, several suspects that this body has been running in the mountains, when thousands of ravines are contending. ”

The seventh paragraph: In the high-pitched area, the overtones are clustered, first descending and then rising, and the sound momentum is greatly reduced, just like "the light boat has passed, the momentum is like a feint, sometimes the aftermath is a rock, and sometimes the swirl is slightly wet." ”

Section 8: The variation reproduces the previous song-like melody and adds new musical material. Slightly fast and powerful, the music is full of enthusiasm. The sound of flowing water at the end of the paragraph is recalled, which is evocative.

Section 9: The carol-like melody is triggered from low to upward, full of passion. At the end of the paragraph, the seed material from the fourth paragraph appears again, and finally ends on the palace tone. The eighth and ninth sections belong to the "revival" part of the guqin music structure.

The overtones of the epilogue make people immersed in the thoughts of "Yangyang, the hope of the ancient tune".
