All four of them are Geoff, and all of the voices are his combined in layers. Many of his videos have him as multiple characters, usually with the different versions singing different ranges.

It’s called a Geoffquake 😂❤ All guys/voices are him, even the high harmonies.

The backing vocals are the Geoff Choir. It's all him, layered at different pitches.

In one of the tutorial videos on his channel, " What's My Natural Range", Geoff casually rips off a 4 octave span and says, "That's about my range without really straining." 4 octaves. Without even trying. For a professional singer's reaction to Geoff, check out Peter Barber's channel. Peter is a professional bass opera singer, so he knows a little bit about singing low. His reaction to one of Geoff's low chest notes: "That's stupid low!"

He also did a cover from the second Hobbit movie. Got the same dwarf's back together for "I See Fire".There is nothing better than four Geoffs.

Geoff is just unique. Usually he sings all the parts in his songs and then he multiplies himself on screen to show us that he is doing all the voices. And of course he is just super talented.😊

The very first note you heard, sung by the Geoff on the very left, was a subharmonic note. And so was the first super deep drop he did. Everything else was sung in pure chest voice. Even that very last note was a chest note, he just pushed a lot of air out through it. Geoff has been working on his voice for 25+ years, and his subharmonics for about 7-8 years now. But he's a low bass, and can do F1's in pure chest on a good day. That's not really something you can just learn to do if you're not born with the anatomy of a low bass. Most basses stay in the second octave and up.

I have subscribed to see more Geoff Castellucci reactions. He also is the bass for VoicePlay. He is singing all the parts and he has a 5 octave range. Welcome to the rabbit hole of Geoff & VoicePlay. I recommend watching Geoff sing: I see Fire; Jack's Lament; Ain't No Sunshine; Wicked Game; 16 Tons. My favorite VoicePlay song is Valhalla Calling. A few of their songs are: Seven Nation Army; Nothing Else Matters; Dream On; The Lion Sleeps Tonight; Hoist the Colors; Drunken Sailor; Sleeping In the Cold; Creep just to name a few.

Ah, another case of Geoff giggles!! He works on lowering and raising his voice. He could easily hit G1 in chest, recently lowered to F1, everything below that is subharmonic. If you check the notes it says Arranged, produced, filmed, performed, and edited by Geoff Castellucci. Final mix is done by Ed Boyer who does the same thing for Voiceplay as well as Home Free and maybe Pentatonix. Those three lowest notes were actually the same note, just done in different styles. One reactor played that last note 10 time before he could get a word out. His second Hobbit number, I See Fire is wonderful. I also always recommend his version of Shenandoah.

The rumble. Yes. His arrangement in this is so sensitive to setting the mood and feature his range beautifully.

The four voices, the four images, are all Geoff! He has about a 5 octave range, and great makeup! It is his idea of "solo"! Try his cover of Blackbird. It shows his range and his multiple images well.

The backup singers are also Geoff, he is very talented and has an amazing vocal range, they are all him layered on the track

My introduction to Geoff because I loved LOTR and the Hobbit. He is incredibly talented doing 1) the arrangement, 2) having an insane range, 3) great vision for his videos. He has practiced over the year - he has videos on it which you might find interesting?! He does not mind sharing etc. 🌹🕊. PS: some of his lowest notes are in his a cappella group, Voiceplay's, songs - and those are on other vowels. If you listen to the follow-up to this, I see Fire, you will be able to see what he does on a terrible word! (i.e. "Durin"). Geoff is in fact, special!

Aha! The Geoff-tones/Geoffettes/Geoff-clones strike again! Take heart, you're not the only reactor who didn't realize everyone you see is Geoff, as well as everyone you hear. That's standard for a Geoff solo video, where he sings all of the harmony parts himself, as well as the lead vocals. And he also creates all of the instrument sounds, usually using plug-ins for his keyboards - he's been playing piano since he was a boy, and several of his videos show him playing. Geoff layering all of the vocal tracks is actually how he arranges songs for VoicePlay - he'll send each performer a track of all of the vocals, with their part highlighted so they can hear it and learn their part. On the really high tenors, he says that he sometimes has to take the track down an octave, but everything else he can just sing in their register.

He did a series of three videos on his channel about how to sing low, if you're interested in the technique(s) involved you can take a look there. And he's actually sung that low on some pretty crazy words/vowels, which you'll see if you continue working your way through his catalog.

Geoff's range is A0-A#5 and he can easily do tenor harmonies layered in.

He can do low notes on all vowel sounds, even an E. He did a low E sound in House Of The Rising Sun for instance. He has said that E's are difficult though, but he can do them.

As others already pointed out, in all Geoff's videos ALL the people you see are him, and all voices you hear are his. The ONLY video of his where he sings with other singers is a Christmas song called "Mele Kalikimaka", which features the American Sirens 🙂. Don't worry though, you're not the first reactor who didn't spot them being all Geoff 😅. On his channel he has a few videos where he teaches "how to sing REALLY LOW", they're incredibly interesting and give the watcher the measure of his dedication. He still studies and practices a lot, and keeps pushing his limits beyond what they are on both sides of his range... Which, BTW, if I remember correctly spans from a B0 to an A#5 😁. Now that you watched this one, the natural follow up is the OTHER song from the Hobbit saga, "I see fire", where you'll find again the same characters (four of the Dwarves involved in that journey), with same makeups and costumes but on a very different set and in a different situation and mood. Those two songs go together, and I can't think of the one without the other. Of course, I'm hoping for a third Hobbit song from the last movie of the trilogy 😇. See you next time!

Those are all Geoff - he is astounding. His range is 5+ octaves: A0 (growl), B0 (subharmonics), F1 (full chest), B4 (some mix, not always), Bb5 (falsetto highest). Hear his cover of Chris Isaak's Wicked Games, or Sounds of Silence, or Jack's Lament. VoicePlay is the group that he has been with since 1997. Listen to their latest Sleeping in the Cold Below (Warframe video game).

It's all geoff.....all 4 guys and his sick vocals ranges

Yes, Geoff will do that to you. He has a wonderful quality to his voice. It's not just the range, it's the tone. And of course, his arrangements. He's very special. Also he is creating all the musical background, on his keyboard, using plugins. And he is singing all the parts, and it's all him, with different beards etc. He records and films all the parts then edits it all together into a harmonious whole. He uses subharmonics to get that low and has made videos about How To Sing Low. It's down to a lot of hard work and time. If you watch VoicePlay's civer if The DragonBorn Comes, you'll hear it start of with Geoff doing a low O or OO sound.

Geoffs chest range is down to F1 currently. He can and does hit full solid G1's in chest. Here, he hits the same note 3 times, but his it differently each time. The first is a subharmonic. The second is chest and the last is a growl technique. His lowest sustained note to date is a B0 subharmonic. All the "male vocalists" in this video are just Geoff in different costumes and make up. The backing vocals are also all Geoff. He records the separate parts then layers them together. He has a couple videos where he demonstrates "How to Sing Low" on his page. Those show us how he does some of this stuff. They'd probably make more sense to you since you teach music, but he's good at dumbing it down for us folks that don't really know much about it. ❤

What a lovely response - I giggled all of the way through. Part is technique - the subharmonics - but part is genuinely very low. As a fan, I've been watching as he keeps pushing lower. He's 42-43 now, so it is probably stabilizing, but he's still pushing, still training. He has videos on his channel teaching people how to do it. (And he most often sings with his mouth small, almost closed. In an interview he said that is what he was taught in high school, and it works for him so he's continued.)

Geoff does tutorials on his channel. He works extremely hard and does everything in the videos himself with his wife Kathy. She's also the production for Voiceplay. Wonderful people ❤️

Yes, the depths below hell. Looking forward to seeing you react to I See Fire from Geoff where all four Geoff's return as dwarves. Thank you!

Well since you already have your questions answered here, I'll just say.....please more Geoff. 😁

Florgasms and Geoffquakes. Put them together and the Apocalypse happens.... Check out Peter Barber, an opera singer and member of the Bass Gang. He does great explanations of Geoff's bass and the technicalities. Whoops - did not see Mrkraemer77722's comment.

Regards your questions, check out his cover of 16 Tons. The reason for that is because there isn't a single subharmonic in the whole song (his words). So that'll give you a wider appreciation to his regular range.

One of my favorites of his. He has a great range.

Geoff has amazing solo videos. He is also part of my favorite accapella group, Voiceplay. I highly encourage you to dive into both rabbit holes. It's a journey worth taking. I have subscribed to your channel in anticipation of seeing your journey! Enjoy!!!

Great Reaction to a phenomenal Bass singer.

All voices Geoff.

You might want to check out Ain't No Sunshine and House of the Rising Sun by Geoff, or his cover of the Beatle's song Blackbird.

Geoff and Layne have done a few interviews about composing and singing with reactors, you should reach out

Looking forward to seeing more of your solo Geoff and VP reactions!

There are multiple ways to initiate subharmonics. Throat singing, there's using vocal fry, I've also been able to intimate a harsher sounding sub by focusing sound through the sinus cavity in the throat. Geoff has a couple of videos on his channel on how he sings low. Great resource for it actually. Obviously, it helps to have that innate depth to begin with. For example, I can sing down to b1 in chest most days, might hit a G1 first thing in the morning on a good day, but I'd definitely say b1 is normally bottom of the barrel for me in chest voice as far as a reproducible daily tone, but it's in that soft tambor that doesn't have a resonate umph to it. But as far as a comfortable low note, D#2 is my normal "don't have to warm up, it sounds resonate" low note. And from that note I can usually pop a subharmonic to drop a full octave. So from there, depending on how I attack it, I can hit everything from a D#1 through probably an E2 in subharmonics, though obviously after that normal D2 it'd be best likely to sing in normal intonation. Subharmonics are fun and when practiced, an interesting way to extend your lower end. It takes a lot of practice to really make it blend with normal notes, and a very intrinsic knowledge on where your own voice settles. And obviously tons of practice.

Yes, he used the "bass"ment note on the word "Gold" initially and "Day" at the end. I can't remember the middle word. But, he does have a tutorial on how he sings low on his channel kzfaq.info/get/bejne/jrF8lLx4rbDTeoE.html Enjoy!

As others have noted, he does have tutorials available online, and he uses 'subharmonics' to achieve those super low notes. The first time someone described harmonics to me, it was along the lines of: "He isn't singing that note, you're just hearing it as that note." And that didn't make sense to me, because pitch is still dependent upon a certain wavelength being produced. With future explanations sought, I guess what makes sense to me is that the technique involves engaging his 'false vocal cords', or the tissue that is in front of the vocal cord folds, and the vibration produces the lower note. So, yes, his larynx and vocal cords are in a sense in the position that they would normally be to produce an E2 when the engagement of the false vocal comes into play to 'turn it into' an E1. This, along with this version of "Sixteen Tons" have always been his most-viewed videos, but I have to say this song itself never did much for me, despite it being wonderfully arranged and sung. I MUCH prefer his other 'Hobbit Dwarf' song, 'I See Fire', and I hope you check that one out also. It is much more beautiful and emotional to me, and you really get to hear him stretch into the top of his range as well.

It is a visceral reaction, certainly.

He can sing every thing xd. All yr questions been answered now

Geoff does a cover of "House of the Rising Sun" and he hits super low on "Sun".

After this one, you will need to react to the second one from Geoff - I See Fire (Desolation of Smaug).

It's fun to sing the lows 😅

This gives me an A-I vibe.

the high one is him aswell :D i mean those all are geoff :D all 4 of em :D

Remember, Geoff goes high as well as low! All the vocals you hear on Geoff's videos will be his- if anyone else shows up they are always credited. But generally speaking (I can, in fact, only think of one instance on his solo channel with guest vocalists, and that's Mele Kalikimaka) it will always be him providing any BGVs. This video in particular fools people, because the makeup work and video editing is good enough that if you don't look closely you may not realize it's all Geoff in various degrees of hairiness. Geoff has a number of videos on his channel where he discusses his vocal techniques. The first shockingly deep note is a subharmonic (and that's a technique Geoff does talk about quite a bit in those tutorial videos), but the other two if I recall correctly are chest notes. Geoff claims to be a natural baritone 'with some bass notes' (*cue massive eyeroll*, lol), but he has definitely worked hard to develop his lower register. We've heard lots of different vowels at those depths; he has remarkable diction for someone singing as low as he does. He's also one of the most agile singers I've ever heard, being able to bounce all around his range with no obvious effort. Other than what Geoff himself has said in his videos, I just assume it's magic because it's easier to understand; I've never heard another voice like his. Other than that, some of what we hear does come down to compression and getting right up on his microphone during recordings, but that hardly takes away from how impressive it all is. And oddly enough, as impressive as this song is with its very, very bass-y notes, it's one of Geoff's least dynamic arrangements. You want to see something really impressive, in terms of arrangement, check out his cover of God Rest Ye Merry Gentlemen. He gave that old carol new life.

❤️

Geoff "was that an E1" Castellucci, lol. Course now he can go to a B0. But that E1 was his showpiece for quite awhile. He can do it not only on any vowel, he can do it on consonants

He has some teaching videos on his channel, if you are interested.

The other singers ARE Geoff different costumes

If your think the Pentatonix's Kiss From A Rose was good then you should listen to their o Holy Night. I can't choose between the 2 which is the best!
