This is Tsu, a voice trainer. How are you all doing? This video is Number_i’s Romeo and Juliet, and I would like to listen to it and analyze the singing voice . Tsuru’s vocal room. Well , this time, Number_i’s Romeo and Juliet was released on the Number_i official YouTube channel on May 19, 2025. I really wondered what I was doing for these two months. However, since I noticed it , I would like to release the singing voice analysis videos of Number_i’s songs as a top priority, so I hope all of you will look forward to it. So, with this Romeo and Juliet as a trigger, I will be releasing the singing voice analysis videos of the other three stations, Idog, Frisco, and Psycho, one by one . If possible, I would like to release all of them within the next week, so I hope you will check them out. And this time, I analyzed the singing voice of Romeo and Juliet , but Number_i is the best after all. I thought the evolution of the voice was terrible . There were parts where I was surprised that she had such expressiveness , and there were also parts where I was surprised that she had such a singing voice , and I was really moved by being able to feel the background of Number Eye’s efforts this time as well . I have analyzed the singing voice more carefully and in detail than anywhere else , so please stay with me until the end of the video. And if you are watching this video for the first time, in the description, there is a URL for a playlist that compiles all the singing voice analysis videos of Number Eye that have been released so far in Number Eye’s vocal analysis video . If you are interested in the singing voice analysis videos of other songs in this video, please click on the URL of the playlist and check out the singing voice analysis videos of other songs. Tsu’s Vocal Room, this channel, is a channel where I, Tsu, mainly publish reaction videos and singing voice analysis videos that convey the charm of artists that I am currently interested in from the perspective of a voice trainer . If you are interested in what I have said, please subscribe to the channel and give it a high rating. Let’s start with the analysis of the number Aromijuri. Yes. It’s cool. Wow, this atmosphere is irresistible. The atmosphere with a very comfortable beat is the best . As expected from a song produced by Jinguji-san, I think it has some funk elements in terms of the musical genre . That daddy -like sound of the guitar. That is, you know, an effector that changes the sound of the guitar is used. It’s a little complicated, but it’s a tone that goes ” wah.” As the name suggests, it’s an effector that changes the sound of the guitar to a “wah-wah” sound , and I love this sound. Let’s continue. Here we go. Wow. This hand-clap feeling. Wow. Did you hear the rhythm just now? There was a point where he beat out some very complicated rhythm , but Jinguji-san’s musical knowledge is amazing, producing such technical rhythm patterns . Sorry. I stopped before the song . Well, this is an atmosphere that is quite intriguing for people who know music, even at the intro stage . Let’s move on to the next part. You see, this part. Ah, ah, sorry. I got too excited and had to stop again, but so far, there was a complex rhythm pattern . So, I guess Hirano starts the opening. Let’s go. Ah, as always, it’s a cool low voice. And the beat of the whole song is like this, isn’t it? It’s a rap that is very faithful to the rhythm, as if the rap rhythm is precisely applied here . And the way he produces his voice, Hirano’s low voice is a very special way of producing his voice. He mainly uses the thick voice called air resonance, or the point that expresses the thickness of the voice, to make the voice resonate , and he puts that voice in his nose. By putting it in his nose, the low part is further emphasized and it becomes a very cool voice, and Hirano produces the low voice in this way. And if you produce your voice in this way, you can produce a very low voice . For example, if you produce your voice in the normal way, it’s aaaaah. This is the limit , but if I change the way I said earlier to resonate my chest and put the voice in my nose, I can produce a very low sound like “uh” . Hirano uses this. Let’s listen to it again. It has a comfortable sense of rhythm. And, to go even further, he also uses the technique of cutting each sound subtly throughout , staccato. I think that using staccato is what leads to a singing voice where the off-kilter rhythm is further emphasized . Let’s go next. Yes. So, I think the part now is Jinguji. Jinguji uses the chest resonance that I mentioned earlier with Hirano, but I think that the space in his nose that adjusts the tone of his voice, the tail-air resonance, is stronger . But he also uses his chest firmly, so it’s a great voice with a sweetness that also expresses masculine coolness . Let’s listen to it again. Yes. It’s cool. There’s a bit of a shout-voice-like rumble in there, isn’t there? Shout-voice is a voice with a rumble like “ra”, but he uses this period called the “temporary ecology” to make his voice. To explain it in simple terms, he sings rap with this throat-clearing voice, and I think Jinguji uses that technique. Let’s move on to the next one. I don’t know this “might” either. I don’t know it at all. Yeah. As expected. I think it’s a way of making a voice that’s mainly nose-based. It’s the Misora ​​resonance I mentioned earlier. Singers who mainly use their nose tend to have unique voices . He’s really good at using his nose. And he has great pronunciation . His singing ability is amazing, even though he sings such fast phrases and the words are so easy to hear. Let’s listen to it again. I don’t know this “might” either, it’s so amazing that it makes me laugh. And at this point, he sings in one breath without any stops. His breath control is also outstanding. No, really, I think his singing skills are at an incredible level. I guess he does a tremendous amount of training on a daily basis. Wonderful. Let’s move on to the next one. Morning to night is good after all. Yeah. Hirano’s singing here, the staccato I mentioned earlier is used with great emphasis. It’s the part where he steps on the ins and says things like “breaking through space” and “rain from the morning”, but he emphasizes the staccato here . And he says “holding a ‘goppa’ at night” , but what does this “goppa” mean? It’s a type of microphone. I think it’s probably the most famous microphone in the world, but there’s a microphone called 58 made by a manufacturer called Shure, and it’s commonly called a ‘goppa’ . So I think he’s saying that he sings with a microphone at night . Let’s listen to it again . Yeah. Right, the part where he says “holding a ‘goppa’ at night is a microphone. No, the way he cuts this sound is intense. It’s really cool. So, what kind of action should I take in terms of singing to cut off the sound so cleanly ? I hold my breath. I put in a little figure. This is the accent in music, but the sound after this accent is a strong sound called an accent, so this part is emphasized and sounds really cool . It’s the best. Let’s go next. I like Jinguji’s singing voice, but I feel like it’s become more powerful, but am I the only one who thinks so? There’s a great sense of beat, but the voice expresses a very fluffy atmosphere. I think Jinguji hasn’t used this expression before. I’m very sorry if I’m not well-informed. Let’s listen to it again. I see. His voice is very soft, but the strength of his words, the staccato, and the staccato. He sings with a lot of emphasis on how he uses them. So that’s why he creates a voice that’s a mix of gentle and powerful. I see. It’s a wonderful expression. Let’s move on. Eh, well. Yes. Well, I think the biggest point of the evolution of Jinguji-san’s singing, as I mentioned earlier, is the use of the staccato and the staccato. It’s really cool, isn’t it? This kind of rhythmic singing technique is not something that can be easily acquired through voice training, so I think Jinguji-san must have practiced singing a lot . Well, Number Eye is the best. Let’s move on. Here we go . Good. The knight’s voice has a charm that makes people smile when they listen to it. I feel like he can convey messages and feelings through his songs. Let’s listen to it again. Good. And this voice has more nasal components than the knight part. I use this vocal technique, where I put my voice in my nose until the nasal elements come out , but if I make the voice too nasal, I lose control of the voice . Generally, it’s a way of using the voice that makes it easy to tense up the body, but I think this is a wonderful voice with perfect control. Let’s go next. Wow, stylish. Here we go. Yes. It’s cool. Chorus. There is a part here where Hirano sings the same melody an octave below the main melody . An octave is the relationship between the notes above and below Do Re Mi Fa So La Si Do, and when the phrase that uses this part division comes in, the atmosphere of the voice becomes very transparent and the sense of style is doubled. I think the stylish feel of this melody of the mysterious rust and the octave match really well, which is a beautiful point. Let’s listen to it again. Hmm. This rap-like phrase that comes in as a follow-up is cool, isn’t it? No, the arrangement is just amazing. It’s cool all the way through. It’s an arrangement that has been pursued . It’s stylish. No, I love songs with this kind of atmosphere. Let’s go next. Eh, does the knight take over the octave lower from the end of the B melody? I thought the low tone of his voice sounded like a knight. Sorry if I’m wrong. I ‘d like to ask everyone at Irie to follow up in the comments, but I think it’s common to harmonize when you sing this rusty , but I think this simple is best feeling of moving forward while keeping this octave is the coolest. And I feel like Hirano’s high temperature rust has amplified the sparkling and glittering components even more than before . And the way Hirano-san sings this point of sabi uses a lot of sounds such as nasal, head resonance, and head resonance. And as I said before, the flower is the point of adjusting the voice quality and creating the tone of the voice, and the head resonance in the head is called head voice in English, and this sound is the point of adding a sparkling component to the voice . It is extremely difficult to master this sound of head voice , but Hirano-san is perfect. He controls the sound of his head voice and sings sabi. I realized now that Number Eye really does a lot of practice. Let’s listen to it again. Look, look, it’s a really sparkling voice. Wow, it’s the best. Now that I think about it, I saw a clipping of Miyataku-kun’s live broadcast a while ago , and he said that the tobe artists practice a lot . And he said that the members of Number Eye in particular practice a lot . No, I’ve always thought that the members of Number One practiced a lot , but when I heard the evolution of their voices, I thought that they practiced much more than I imagined. It’s amazing. Let’s go to the next one. Continued. Wow , cool. Super cool. I guess Jinguji’s position or role this time is to express a manly, sexy look. Until recently, I had an image of Jinguji as being cool, stylish, and beautiful , but this time in Romeo and Juliet, I think that my image of Jinguji’s style has been completely destroyed in a good way . It’s so cool. Let’s listen to it again. It continues until. It’s amazing. As expected, the attack of the sea has become so strong. No, this is too amazing. It’s really cool. Let’s go to the next one. But if that’s the case here. Wow, that’s good. So it’s like going from Jinguji to Hirano again. So, Hirano-san is in a position to sing in a beautiful way this time. His singing voice is really beautiful. The use of Misora ​​and head voice that I mentioned earlier is an influence, but let’s listen to it again. If I were here, I would laugh at this point. Yeah. It’s the best. It’s so great that I can’t stop grinning. I’m sure there are many Iries who have had the same experience, but Romeo and Juliet is a really wonderful song. Let’s go next. Hide your complexes. Yeah. Yeah. Oh, maybe about the last two phrases. I think this is the point that leads to Hirano-san’s rap after Ki-san’s singing. No, I really think that even though Ki-san’s rap has such fast phrases, each word can be heard very clearly, which is an amazing technique . I don’t think you can hear it so clearly normally. I think he really studied each word carefully, pronouncing it, and this pronunciation is audible. I think he studied this pronunciation and created this rap by studying it in that way . Otherwise, I don’t think he would be able to complete a rap where the words are so clearly audible . Let’s listen to it again. Yeah. Yeah. Yeah. He changes the way he sings a little bit just at the top of the last verse . The cup part was centered on his nose, but the last part sounds like his nose plus his chest. He uses a voice that’s a little manly and sexy , but I think that the way he expresses sexiness just in this one verse is unique . Wonderful. Let’s go next. I do n’t want to go back to Nita Ai no Jikan. Right . Yeah. It’s cool to change parts so quickly, with a sense of speed. And Hirano-san used a very sparkling voice in the chorus, but when he raps, he changes to a low-pitched , extremely manly voice. There’s no gap. And the knight’s rap also uses a thicker voice in the second verse than in the first verse . It’s like he’s singing the rap in a way that’s similar to how he raps in the upper verse . No, this change in atmosphere is irresistible. Let’s ask Hirano-san about your connection again. Look, look, look, the nasal voice is emphasized just as much as in the first verse, but by adding to that, the knight chooses a distinctive love room plus a manly voice by using chest resonance . He really controls every detail to create his singing voice. It’s really amazing. Kiss-san, let’s go next. Yes . Jinguji-san’s voice is also different from the first verse. The key to Jinguji-san’s voice here is the space in his mouth, the air, which is the main focus. It’s a point that makes the voice that you usually use when talking resonate, but if you use it mainly, the atmosphere of the voice you use in everyday conversation is emphasized. Plus , the words sound clearer, or so it has those characteristics, but it’s a little, but I use a voice nail that makes you feel like Jinguji-san’s phrases are talking to you . Then Hirano-san’s singing voice afterwards is a nasal voice plus chest that I explained earlier with Takeshi-san. He sings with this balance of voice resonance. Let’s listen to it again. It ‘s cool. Jinguji-san’s point. After listening to my explanation, It’s a rap, but didn’t you feel a nuance like a story? When this kind of atmosphere comes , I feel like the world view and message of the lyrics are really conveyed, and I love this kind of voice. And in the second half, Hirano’s manly but sweet voice closes the second verse. It’s a great flow. We’ll move on to the second verse. Yeah. Isn’t this bouncy feeling that’s like a tumble really cool? This bouncy feeling, the use of the little voices I explained in the first half, creates a bouncy feeling, but this voice and this beat are irresistible. Let’s move on. Yeah. Isn’t Ki’s voice amazing in the first half just now? It’s like a voice that explodes with individuality. And here, I wonder if he’s deliberately singing in a vague way. Up until now, every word was too clear in a good way, but in this part, he used a way of pronouncing that made me want to listen to his voice very closely . And then Jinguji-san’s beautiful and stylish voice, which is my favorite of Jinguji-san’s voices. This connection is also cool. Let’s listen to it again. No, it’s good. It’s too cool. Wow, Number is just too cool. The expression is like a treasure. I think I said this before in some video, but the expression of the singing voice is like opening a treasure box, and the moment you open it, a lot of sparkling things come flying up , and I feel that kind of atmosphere every time I listen to Number’s songs . The more the song progresses, the more different expressions and different voices overflow . I don’t think there are many artists who pack so much charm into their songs. That’s why I think Number Eye is amazing. Let’s go next. Riun . Is that voice Hirano-san? I think it’s Hirano-san, but again, you’re using a voice I’ve never heard before. Here, Hirano-san uses a voice that is centered on air resonance, but I think that he is using almost only the sound of air resonance . So, when you try to sing with your mouth as the main focus, like now, your chest and nose will naturally resonate a little, but Hirano-san’s voice right now is really almost entirely his mouth. This way of producing voice is amazing. He is controlling the natural sound of his voice and concentrating it in one place, so he is creating a natural flow of voice. No, this is amazing. Let’s listen to it again . Yeah. Super cool. This voice, this, in a good way, a languid atmosphere. This is cool, isn’t it? It feels really cool. No, it really feels like a feast. It’s too cool. Let’s go next. Yeah. Do you notice that I used a really stylish sound in the first half? And I think Hino’s sound is “gogo”, but the second sound of the lower part moved in a really stylish way. Sorry . I used to be a professional chorus singer, so I ‘m really interested in how this kind of “oshinaha” is pronounced. Let’s listen to it again. See, the second sound goes down like “gogo” . This part is also really stylish. And I don’t think they used this harmony in the first verse. This stylish harmony that you can only hear at this point in the second verse is the best. Sorry. I’ll stop it short and move on to the next one. Okay. Yeah. Did you all just hear Jinguji’s wild pronunciation of the words? I mean , I’m sure you’ve probably heard it many times , but Jinguji used a really cool way of pronouncing them. And by mixing that cool pronunciation with a nasal tone, he has created a voice that is cool but sweet . Let’s listen to it again. No, it’s too amazing. I mean, his range of expression has expanded tremendously. I thought he had great expressiveness a little while ago, but now he’s a number one who shows off even more expressiveness. It’s amazing. Let’s go next. Yes. Yes. Is this voice Kiss? Sorry if I’m wrong. I think it’s Kiss. ​​The sleepy tone of his nasal voice, and the fluffy stability of his voice. I guess it’s Kiss. ​​And, of course, his voice is wonderful, but the relaxed feeling of this rhythm is irresistible. I think it’s a voice that you can listen to at a leisurely pace, and that matches the relaxed beat of the song very well. Let ‘s listen to it again. Yes. Yes. It’s cool, isn’t it? It’s so stable that it’s like it’s wrapping the whole thing up, and it gives me a sense of security. Let’s go next. Cool. Like wow. Not wow, but like wow, he’s using a really fake. Now, this is the last point, let’s listen to it again. Look, look, look. The last part is very detailed. There’s an R&B-like fake, but I love this kind of thing. Super cool. Let’s go next. Hmm. Cool. Even when the sound goes up, he keeps the chest resonance firmly, so his voice is thick and he’s singing a high note. Now, it’s Hirano’s part, and it’s very difficult to keep a thick voice even in a high range. The way to do it is to not reduce the chest resonance, the air resonance, even when the sound goes up, and this is the most difficult thing in history, but for now, I’m singing using the voice that plays Hirano. No, it’s amazing. Let’s listen to it again. To be continued . To be continued. This is amazing. And in the first half, he uses a low, shouting voice. It was a great point that he keeps the strong, low, masculine voice from the first half and continues it all the way to the higher notes. Moving on. Continuing on lol. Yeah. I just thought when I heard Hirano’s voice, Ki’s voice has a boyish, naive feel to it. And Hirano’s voice is really thick and masculine, and I think the rust here expresses the difference in the ages of the characters. I’m sorry if I’m saying something off-topic, but the gap between the characters of Koesu is so big that I got that feeling , and I had a really good image in my head. No, it’s wonderful . Moving on. He becomes “I’ll bite your eyes.” And here he becomes Jinguji. Jinguji’s voice is really beautiful. I love this difference in elegance. But it’s not just beautiful, she uses a powerful voice, so her emotions reach your heart. Let ‘s listen to it again. It’s nice to see her catch your eye. It’s soothing. Jinguji-san’s voice is amazing. Let’s go next. Yes. There’s a saxophone or something in the background of Jinguji-san’s beautiful singing voice, and the interplay between the saxophone phrase and Jinguji-san’s singing voice is really cool. Let’s listen to it again. Yes. I think it’s not a saxophone, but a trumpet. It has a high-pitched sound. Maybe a trumpet. Sorry, I said saxophone. I think a saxophone would have a thicker sound and play a lower range, but she was playing a higher note just now, so it’s probably a trumpet. Let’s go next. Good. Yes. This voice, this voice. I thought that this voice was the one that Kiss-san was known for, and after all, Ki-san’s voice with the emphasis on the use of the nose, plus the overall cut sound. I think the staccato is quite strong, but when I first heard Number Eye’s song, I think it was Inazuma. I was blown away when I heard Kiss’s voice, and every time I hear this voice, I remember it. Let’s listen to it again . It’s good. No, it makes me happy. When I hear Kiss’s voice, the song that got me hooked on Number Eye is Inazuma, so every time, Kiss’s voice reminds me of that . No, it makes me happy. Let’s go next. Yes. It’s soft. It’s good. The sound cuts off like a sound. I was surprised by the atmosphere at the end of Sabi, but that’s Jinguji’s point now. The atmosphere when Jinguji’s voice suddenly changed to a falsetto for just a moment was really stylish. Let’s listen to it again. See, see. Yes. It’s cool. The feeling of this falsetto voice suddenly changing. Number Eye’s Romeo and Juliet was the coolest. This concludes the Number Eye Romeo and Juliet singing voice analysis. No, it was too amazing. The song is very interesting overall, but it expresses the emotional blessings of the singing voice throughout the entire song, and there are intense parts, gentle parts, and warm parts, and I think that it is a song that combines various elements, which is Romeo and Juliet . I will continue to release singing voice analysis videos for the other three stations, so I hope you will come and see them again . I would like to continue to follow Number Eye with all my might. That ‘s the end of this video. If you liked the content of the video, please subscribe to the channel and give it a high rating. Well, that was voice trainer Tsuru.
