Top 10 Quotes from Vocal Coach Reactions to Dimash Kudaibergen Vocal Performances
I know Dimash was spam-voted on this site, and this didn't do him a favor. I don't like spam voting either, and knowing that Dimash was spam-voted here postponed my willingness to give him a listen. I thought he was just the next talentless local star who got spam-voted. Now I know I was wrong, but spam voting was the reason I avoided giving him a try.That changed in March 2019. One day, I was bored and decided to have some fun by listening to a cringy singer. Oh, how wrong my expectations were! He was so good that my jaw dropped, literally. At this point, there aren't many things in music that can impress me, but Dimash did. Yes, Dimash is an extraordinary singer, and his vocal skills are mind-blowing.
Dimash probably doesn't have many fans among the users of this site, but I wanted to make this list because I have a point to make. I've noticed that Dimash has been getting some unjustified hate on this site, maybe due to bandwagoning. Perhaps the majority of his haters have never heard a single song by him. Or, if they have, and still claim Dimash is a bad singer, then those individuals completely lack basic music judgment, especially vocal judgment. There was even a comment saying he's off-pitch. No, Dimash's pitch is unbelievably perfect, and vocal coaches emphasize this as well. Off-pitch singers are probably the favorites of the people who claim Dimash is off-pitch.
If you don't like his music or his voice, that's OK. But to say he's a bad singer, or even the worst singer of all time, makes you look musically ignorant and mean.
Spoiler alert: All the vocal coaches I checked out (over 15) highly appreciate his vocal abilities. This list focuses on videos where vocal coaches react to Dimash's vocal performances. In my original Top 10, I included only reactions to his live vocal performances because if a singer is absolutely awesome live, that singer might be even better in the studio. Also, in a live performance, the singer can't change or replace a bad "blue" note.

D8 is an insane whistle note he hit live in the third part of the song Unforgettable Day, Gakku concert 2017.
It sounds like a whistling kettle. He held the note for a whole five seconds and even added vibrato to it! Adding vibrato means he had full control over the madness that D8 is - its frequencies are ~4,700Hz, and he was able to modulate them! Oh, and the note matches the key of the song as well as the notes the band was playing when he did the whistle. Also, one second after that note, he continued singing, and because he was on his knees, he was getting up at the same time. He made it look like nothing.

Tara Simon is one of the vocal coaches on YouTube who provides the best explanations of what's going on vocally, and her reactions are also very spontaneous. I recommend watching this entire video - you'll learn a lot from Tara. If you've never heard of Dimash, this is also the video I think is good to start with.

Dr. Marc Reynolds isn't a medical doctor - Dr. is his academic degree, Doctor of Musical Arts (he was the teacher of some singers and vocal coaches on this list). He's an expert in opera singing and opera stage directing. He's a professor at the School of Music faculty and Director of Opera Studies at the College of Fine Arts and Communication (Texas State University).
This quote, coming from a person like Dr. Marc Reynolds, is a HUGE, HUGE compliment.

I'm trying to help you do that. Hahaha! - Christi Bovee]
That was her spontaneous reaction after watching him for the first time (live performance). She admitted that training and practice can't help people do everything Dimash does, "hahaha." She added that he is "freakishly talented." However, the vocal coach who admitted this after a deeper analysis is Dr. Marc Reynolds, who pointed out that Dimash's vocal instrument has an extension that is "just his genes."

Dimash's range is 6 octaves and 3 notes! Vocal coach Adam Mishan wondered whether there was some digital effect in a section of the song, but he eventually decided that there wasn't, and that Dimash most likely achieved that with his voice. Yes, that's correct - there was no digital effect. Dimash accomplished it with his voice, using a singing technique and style common in Middle Eastern folk music (Asian Middle East).

It was funny how Ken Tamplin was trying to find that note on his guitar, only to discover he didn't have a fret for it, LOL.

Wow! Effortless for him. Wow! Oh my gosh! Wonderful! All right. Wow! - Valerie White Williams]
This wasn't the first time she saw Dimash perform live. Valerie White Williams is from Vocal Splendor Studios.
This comment is about Dimash's live version of "Diva Dance" from The Fifth Element movie. What he did effortlessly in 2017 (Bastau Concert) is one of the hardest things in a soprano repertoire. The climax is only one minute long (Dimash sang that part), but it's a true headache even for the best sopranos. The soprano who did the original version never attempted it live. Dimash sings it only live and nails it.
This part of the OST was digitally processed, and the voice was modified to sound like alien talk and singing. Dimash imitates alien talk with his voice. LIVE.

Dimash doesn't need any autotune to sing well.

The Newcomers
Yes, Valerie used two words that I personally would use to describe his voice: beautiful and free. It really feels free because his voice is so fluid and seamless that it floats freely wherever Dimash wants to go.
I feel that freedom, and this is a great feeling. No cracks or strain in his voice. I've watched perhaps over 100 live performances by Dimash, and I have never heard him running out of breath, power, control, etc. Even that insane D8 was controlled.

She's an opera singer, and Dimash is singing opera in this song, so it's a great compliment.

Well, I can relate to this: his range of over 6 octaves and his perfect pitch have blown me away, too.

Besides that talent, there were 20 years of training and practicing - several hours a day, every day. That's why she also said, "When you see someone of THIS caliber giving a performance like that... this boy has sacrificed to get into the vocal shape that he is in."

She said that around 10:15. Emi Pellegrino is one of my favorite vocal coaches on YouTube because her explanations and demonstrations are very good, her reactions are very spontaneous, and she's also very entertaining because she has a sense of humor.
And yes, Dimash was very sick and was getting shots/injections in his throat.

Yup, ET detected, haha.

Perhaps that was the first time she listened to Dimash because, during the first several minutes, she was kinda speechless - if we don't count "wow," "oh my god," "what?," and "oh my gosh."
At the beginning, her facial and body expressions were more valuable.

It was a live performance, and Dimash mysteriously smiled before doing the next insane thing. That smile was like saying, "You think I can't go higher than I just did? Umm, watch me." And he sang the chorus even higher - and killed it.

Yup, from the top to the bottom of the whole 6 octaves and 3 notes!

Here's the entire quote: "The high notes didn't surprise me - I know he's got super high notes, so precise. But that low range is incredible. I've heard a lot of tenors that have these really awesome high notes and whistle up to the top of the piano, but not everybody has the low notes that he has." - Valerie White Williams from Vocal Splendor Studios

Definitely agree. He became known for his high notes, but his beefy baritone lows are awesome, too. Sometimes he even gets a bass-baritone-ish sound (for example, in the song Ogni Pietra).
because I'm the only vocal coach with perfect pitch, so they told me to analyze his range […] and Dimash's lowest note was A1, and his top note was D8 (so far) - fahimmuchi]
My previous comment got too long, but I want to add something: many internet sources use outdated info about his range - they didn't include his newer songs. Sources usually mention E2 or F2 as his lowest notes. That was true in 2017. But he later made a song with C2 (Sinful Passion) and in 2019 - with A1 (Love Is Like a Dream).
Also, some sources mention four and a half octaves or five octaves. This is old-school counting that doesn't include falsetto and whistle register - four and a half octaves is pretty impressive if you clarify that this is his range in the modal register only.

Actually, many coaches noticed that long before this performance on June 21, 2019. I also noticed he's owning the stage - it's undeniable.
The "authority" depends on the song. In some songs, his character is vulnerable, and he shows that. But he owns the stage again, thanks to his vulnerability. Incredible.

Yes! I thought the same after hearing his new song "Ogni Pietra." A duo involves 2 people, a quartet 4, a sextet 6, and an octet 8. Dimash certainly has at least 8 different sounds in his voice, both male and female. This new Dimash song is another thrill for vocal coaches. Dimash had never ventured into "full-on" opera before, but he did it 3 days ago, on June 21, 2019.

Gurrll, calm down! […] And that last note - perfect mix. Perfect.Even.Mix!!! - Emi Pellegrino]
Emi is young, but she's very competent and entertaining. She explained and demonstrated many things (vocal fry, vocal cry), and I particularly appreciate that she correctly identified what Dimash was doing in a section: it wasn't in falsetto like most people/teachers thought, it was a masterfully used breathy chest voice. Like Emi said, "It's very hard to do, and it just again proves how awesome he is. Yeah, I'm a Dimash cheerleader. I need to get a shirt."
Another plus is that she can tell what notes Dimash hits and with what vocal technique. I also liked many funny things she said and demonstrated, such as "talking on a normal basis like a normal person," how some "basic" girls talk, and more.
