This music video is so clever, so pleasing, so simple, so elegant ... it makes us smile, laugh, and grateful to hear such mastery.

No instruments + no words = Grammy (2nd). This is a masterpiece! Great reaction! ☺️

Laughter from joy is a wonderful reaction and much appreciated. PTX brings joy.

You don't need to apologize, your reaction was perfect! The music industry said you can't do an a cappella version of an instrumental music piece. PTX said WATCH THIS!!

Your laughter indicates joy.

"God rest ye Merry gentlemen" is very similar and great. I recommend it to you.

An instrumental with no words…performed by a group with no instruments! Your reaction was PERFECT!!!

It’s funny because it’s so full of surprises. I enjoyed watching your delight.

Laughter and disbelief was my first reaction, too! Followed immediately by shock, awe and stunned silence. What creativity and raw talent are capable of astounds me. Great reaction...keep sharing the joy!

This video definitely shows off Avi’s classical singing training.

Hey Lex! The very idea of an a cappella cover of an instrumental classic confounded me until I saw this. Only PTX could conceive the idea, let alone pull off the execution so impressively. Thanks for posting.

I love this song... as a PTX fan once said, it is a song without words sung by a group with no instruments. I love how Pentatonix are willing to take any music apart and re-think it. I also hope you are not offended by their irreverent treatment of your iconic composer, Tchaikovsky. They have made him fun, and introduced his genius to many that may never have heard him otherwise. Great reaction, as always.

You laugh because it makes you happy and we like watching PTX make people happy 😁

the first time I ever watched the video, I also giggled in joy!

Please do not apologize, it just means they make you happy and joyous!! Like some one crying when they feel that kind of emotion in a song. It's your reaction, glad to see the honesty you give us!!!

You keep laughing because you are overflowing with pure joy! I ❤ your reactions!!

They surprise you with something every time. I enjoy your reactions.

Pentatonix love to make you laugh sometimes at their videos

This is one of my favorites. Your laughing is just a reaction of joy and surprise in my opinion. So i love seeing that. Great reaction.

Laugh away - it's the wonder and delight!

Don’t apologize for being delighted by their mastery. I think this video is hilarious. Wonderful to see you enjoying it!

After reading the comments I know that one of the reasons it hit your funny bone was because there were no words. Secondly, they have a great sense of humor and without losing a drop of their artistry, they can be intentionally comedic.

this won them their 2nd grammy

I love new reactors who listen to this......Grammy number 2. Not bad with out singing a note....great job as always...Judy D from NY State

Your delight is a delight to watch!

This song is perfection

Another Grammy winner!

This got them their 2nd Grammy ❤️

Watch their live performance in Singapore "Aha ". Avi goes so deep he shakes the sound system and mitch just goes freaky high

It is fun anticipating your laughs. It makes it fun to watch it once again. Please I'd love to see your raction to "Run to You"

Those coordinated side-to-side head movements also remind me of another Tchaikovsky piece - the Dance of the Little Swans from Swan Lake.

I really loved your reaction. I had to watch this video several times myself, the first time I watched it as also. Personally, I think this was why they were invited to perform the Star Wars Theme at the AMA'S. You should check it out.

It’s fun editing. We all laughed. 🤗

It takes alot to take an all instrumental song and turn it into a Cappello! Is fun and funny! glad you enjoyed it!

Enjoyed your reaction to the max!

Great reaction, I always love the harmonie parts where if you try you can pick out each if their voices, but it still sounds absolutely beautiful all together.

Hello! Thank you for sharing so nice a reaction ;=)

This tune is from the Ballet "The Nutcracker" It is normally performed by an orchestra.

Hey when it makes you happy that's NEVER a bad thing!! They are just scary talented!

The amazing part of this is that it is an instrumental piece, with no words. So, they just sang the parts of the instruments! But keep in mind. They had to sing their part individually in a studio. Then they had to 'sing' (really pretend to sing) it again in a darkened studio for the video. Then hundreds of hours were required to edit the entire thing together.

Avi (bass) has had training with opera, Kirstin has sung on Broadway, Kevin (beatboxer) has classical training with cello.. just a few tid bits..

I really enjoy your reactions and it is very fun watching you. Probably why I’m doing all your PTX videos again. Well that and to comment. This one makes me laugh also, how can you not.

I love this video! 💖

Not only was it written by a Russian composer, I think they sang it in Russian, too.

The creative video is, no-doubt, an effort to make an otherwise static, lyric-less rendition, visually interesting to go along with the amazing audio performance. I laugh whenever I watch this one too.

they didn't even sing one real word and it was still awesome!!!! more PTX please.

I wonder what Tchaikovsky would have thought of PTX's version?

Avi Kaplan, no longer with PTX, but greatest bass out there. His ancestors were originally from Russia before coming to the US.

Great reaction! I very much enjoyed your delight at this masterpiece. PTX said this was one of their fastest music video shoots. Avi said it took less than 30 minutes for his part to be done. I would never have guessed that. They did another Tchaikovsky song from the Nutcracker, Waltz of the Flowers, for their 2018 Christmas album. There's no music video, only the audio, if you want to check out another song without words mastered by PTX. 😁

I loved it that you were amused. I am certain that the humor was put in intentionally, so it's nice that you reacted as they would want you to! We get to enjoy the humor, they get the Grammy. Everyone wins!

Glad to see that they get a thumbs up from a Russian reactor to this piece. It is pretty wonderful.

Hey bro I have another suggestion for you… So you’re videos are already kinda short, which is fine. But when you said at the end of this video, that you’re going to watch it again, I really wanted to see your second reaction too! I’ve also seen other reactors, react twice. This guy Barry watches it first without commenting or pausing (reaction) and then watches again pausing and commenting on the video (review). But whatever you decide to do, I recommend watching it twice in a row right on camera for us! It would make the videos longer and give you more time to process the music and give us a reaction! Peace my Russian brother 🇷🇺✌️

PTX is presenting "Dance of the Sugarplum Fairy" in an "out-of-context" manner which provokes first smiles, then chuckles, then laughter because it makes one feel good.

PTX did a brilliant job on this. As always.

I LOVE YOU

Congratulations. You just got Mitch slapped, and an Avi gut kick.

Some people just tend to laugh at things they really enjoy. There’s nothing wrong with that. Just be yourself.

Don't forget about Scott and Mitchie's "Feelin Myself" (SuperFruit), Mister Russian still in Russia. Not so much xmas music please.

It DOES sound a bit funny for a Russian person, since we listen to this mesterpiece a lot. Music from 'Nutcracker' is hella famous here, so I totally get the laughter being Russian myself. It's just we are so used to the classic version, that smth out of the box is just unexpected. Having said that, I just LOOOOOVE this version! Well deserved Grammy and an unbelievable job done by PTX. They are crazy talents, each of them individually and as a group together. Спасибо за реакцию, подписалась на канал! Обожаю эту группу, вот уж не думала, что найду реакцию от соотечественника.=)) Удачи!

I love the russian accent ngl

Did anyone tell you yet that Avi Kaplan studied to be an opera singer? You can hear Avi by himself but the style is very different either jazz or a variety of choral or folk, country what is called Americana or Roots music. He writes his own music. His most famous one is "Change On the Rise" which has also been used in a TV program Resident Alien and as theme music for the Apple Podcast Relative Unknown. Like Pentatonix each song can be a very different style but it is with instruments now. Or another group like Pentatonix Homefree did a cover of Johnny Cash's Ring of Fire and brought Avi in to feature as the 2nd bass singer. 2 of them both very low 🙂 People like that and there are people who are fans of both Homefree and Pentatonix. The title is "Homefree Ring of Fire ft Avi Kaplan" if you want to hear it.

Lol

Tchaikovsky just for you!!

I wish Tchaikovsky had written it longer.

I loved your reaction. Do you think Tchaikovsky would approve?

Please try some Voice Play. Everything from comic to classical. Especially fine is "Dream On."

React to young drummer boy- act right!

Аааа PTX фандом в рашке жив!))))

One of you pauses was at a really important part of the video and you missed Mitch going sky high. If you pausing (which you have to do) try going back slightly so you don’t miss anything

Very late, but AVI !

It's supposed to elicit all those reactions. Don't be sorry 😁
