Foreword
I hope this ‘Introduction’ can become the introduction of everyone’s youth.
It was a constant reminder of the importance of close friends. To meet them is a miracle in itself.

The lyrics and melody of this song are full of youthfulness, so when I first heard it, I was already unforgettable about it. I am also grateful to have such a group of friends willing to cooperate with me to complete this work.

For the performance part, I initially wanted to use a score that was readily available on the Internet, but I found some differences between it and the original score when I actually played it, so I chose to create my own score for the keyboard part. This time, the keyboard consists of two main parts, one is the piano part, and the other is a sound similar to the synthesis of String+Saw. Not very difficult overall, but very distinctive! At the same time, I tried to play at the beach during this video recording. Although there were many people around, I didn’t feel any stage fright at all. It was also a self-improvement experience, wasn’t it ?

For the video production part, At the beginning of the production, I wanted to make an “ACG” style performance video. After searching the internet, I didn’t find any similar videos. I had no choice but to try to add the elements I had in mind. Many of these elements are hand-drawn, such as some small animations. It is also the first time to try this kind of frame-by-frame drawing, and the process is still very interesting. For this type of music performance video, I think the most important thing is to get the rhythm right. Let the video switch with the audio rhythm, so as to maintain a sense of consistency and enhance the audiovisual experience of the audience. Since the performance of my Macbook is not enough to support me to use Adobe Ae to create many effects, I have to use Adobe Pr with Apple Keynote to finish the animation of some scenes. Although the production is a little complicated, but the finished product is still satisfactory. All in all, it was a very good attempt!

This is the best video I’ve done so far~

And this is the first time I’ve done this type of band ensemble video. Thankfully, the finished product is quite respectable!

又三郎 (Matasaburou)

Foreword
This song is based on a fairy tale written by Japanese national author Kenji Miyazawa, “Kaze no matasaburo” .
Legend has it that around September 1st, Matasaburo, the “son of the wind god”, will come to earth, and on that day, a new student named Saburo actually appears in class. When the children were talking about him and the mountain breeze was blowing outside the window, everyone rightly suspected that he was the KazeNoMatasaburo.
After reading this fairy tale as a child, the author, n-buna, believed, like the child, that Saburo was the “son of the wind god”. But when he grew up and opened the fairy tale again, he found that Saburo seemed to be just an ordinary child from the city, and that he might just be out of place in the remote countryside.
“If Matasaburo could really summon the gale, maybe he could blow away the sense of isolation in our hearts.” With this thought in mind, n-buna wrote the song “Matasaburo”.

When I first heard this song, I was quite fond of his music and lyrics. Among them, for the guitar part of the arrangement, I have to say is fantastic, the melody is very dynamic. So I quickly adapted it to a piano version and played this piece.

For adapting the piano version, I needed to ensure not only the playability of the piece, but also to restore the style of the original as much as possible. Therefore, I gave serious thought to many areas, making the finished product very interesting.

For the post-production part of the video, I also added a lot of my own ideas and took a bold approach to these ideas. First of all, I need to think how to shoot the performance part, which needs to reflect the vividness of the performance, but also needs to ensure the neatness and usability of the picture. Secondly, since it was a music video, I also needed to think about how to combine the video with the rhythm of the audio when editing to make sure that the two didn’t feel strange. Then, I also added a lot of video clips that I shot to enhance the visual experience of the whole work, and experimented a lot with the color adjustment of the video.

In the audio post part, I focused on adjusting the piano tone to make it very distinctive and impressive.

This is my very favorite work

This arrangement also has a demo version of the score https://www.bilibili.com/video/BV1p44y187xB/

3 Pianos - Fight Song

“My power’s turned on
Starting right now I’ll be strong
I’ll play my fight song”

What is the Fight Song?

#

For me, this song has been with me through many difficult times. Whenever I hear it, I can always jump out of the doldrums and start to fight in my own way. Cause I’ve still got a lot of fight left in me.
The only way I can thank this song is by adapting it. And here is it~

In order to show the special atmosphere of the different parts of the song, I chose to use three sets and lighting to complete the work

At the beginning, I was using a normal upright piano without any digital functions. But to improve the audio quality, instead of using a recording, I used the AI audio transcription project to convert the performance to MIDI and used the same software Instrument on the computer as behind. It makes the overall listening experience very consistent without any abruptness.

For the main song and chorus, I chose to use the keyboard with the iPad’s drums for the performance. It can reflect both the production process of this music and the dynamics of the whole song.

In the interlude, I chose to use a reading light at night to create a quiet atmosphere and to better reflect the emotion of the piece.

In the closing section, I deliberately highlighted the visual center in order to better reflect the unyielding feelings that I wanted to express in the song. To give the audience a feeling of never giving up.

Extra : I also added synthesizers, guitars, and bass to the whole piece, making it sound more unique and personal

Digital Piano Recording Tutorial

#

Since this is a Chinese video, I haven’t uploaded it to youtube yet, but I’m working on an English version of it, so stay tuned!

Foreword
Along with the development of information technology, the camera capacity of mobile devices such as cell phones has increased substantially, and more and more people are recording piano videos. However, in the process of browsing videos online, it is found that many people do not make good use of the characteristics of digital pianos to improve the audio quality of their videos, for example, many people use the microphone of their cell phones to record the sound emitted by the speakers of digital pianos, making the audio really bad. Therefore, I would like to share my recording methods to more people by summarizing my own recording experience in order to improve their audio quality.

It took quite a long time to design and prepare this video, almost six months. I took what I know about the excellent methods and took the viewer through the beginner’s perspective to learn these recording methods from the shallow to the deep.

In the beginning of the video, I first introduce the different types of digital pianos to help the novice to understand the characteristics of their instrument.

In the second part, I briefly introduce the meaning of related technical terms, such as MIDI and audio waveform, and introduce the corresponding recording methods according to the classification of the instrument’s interface and functions. I will provide pictures of each interface as examples to facilitate the user’s identification, while in some parts of the operation of the computer software, I will pay attention to the rhythm of the explanation and zoom in on the area I am operating in the video so that the user can do the correct operation with me.

In the third part, I introduce the different soft sources and how to use them to help users better grasp the characteristics of the corresponding sources to make better choices.

In making this video, I spent a considerable amount of time gathering information and preparing the corresponding read-aloud text and presentation slides. During this process, I kept thinking about how to better teach these knowledge and methods from a novice’s perspective, and I kept revising my material. I am quite satisfied with the final product, and I have gained a lot of support and love from people (this video has 22K+ views)

Out of my love for music, I often play many of the pieces I hear on the Internet on the piano. But the fact is that not all of them are found in sheet music. So I will try to make a score by listening to it. Since I am a novice, sometimes I can’t write the right notes exactly when I encounter a complicated piece. Then this is where the AI piano transcription project comes into its own.

It can accurately identify the notes. Whether it is a simple pop piece or a complex classical piece, it can handle it with ease.

It also accurately reproduces the pedals of the music. Its accuracy makes it infinitely closer to the original when playing back the transcribed music.

It has a fast transcription rate. With the help of CUDA acceleration, a 3-4 minute piece of music can be transcribed in less than half a minute. Even if it runs only with CPU, the speed is not too slow.

For this Video Tutorial

For this tutorial, I am also starting from a beginner’s point of view. It was tested at least three times with the complete process before recording the video. Each time, the virtual machine was uninstalled and reinstalled to ensure a pure system environment. I also invited my friends to follow my installation instructions and test them, and the feedback I got was no problem!

When I browsed other computer tutorial videos on the web, I found that when they entered the code, the interface was always small making it hard to see what I was typing. So when I was making this video, I enlarged each code entry for the viewer to see clearly, and added extra code captions to increase the visibility of the code.

Not only that, but I’ve noticed that in many courses on the web, the audio recorded by the instructor’s microphone is always terrible, either too low or very noisy. So for the Ubuntu video, I chose a quiet environment and used a high quality microphone for the recording to ensure the quality of my audio. Having good video and audio quality allows both the learner and the viewer to enjoy the video.

Also, I have prepared a text version of the tutorial for those viewers who find watching videos inefficient.

The reason for making this video is actually that many students came to ask me about this knowledge point during the final exam revision phase. After the exam, while the memory was clear, I made this video immediately, and at the same time, I also considered to consolidate this knowledge point better.

First of all, this is the age of short videos, and everyone likes concise, no-nonsense videos. Therefore, I try to make all the knowledge points as concise as possible when writing the script, so that the audience can understand and absorb the knowledge in the shortest time.

While crafting the presentation slides, I recognized the benefits of using slides: their capacity to animate content, which can vividly illustrate abstract concepts, thereby enhancing comprehension for the audience. Consequently, I incorporated numerous animated transitions between slides and included several hand-drawn illustrations to clarify complex ideas.

In terms of audio, I also try to ensure that the recording is as high quality as possible, so that the audience will not be affected by inaudible learning efficiency. Unlike other tutorial videos, I have also added background music to make the overall video less rigid and boring.
