What's up everybody my name is Jacob Collier and I'm a musician and I'm here to answer some of your questions from the internet.

This is a question from at Rachel Garza 1.

It is indeed the case that there are 88 keys in the piano.

Over the last few hundred years composers have sought an increasing amount of range to work with in their compositions.

So this note here the C8 this is 4186 hertz which is actually a very high note and this note here which is A0 is 27.5 hertz which is a very low note.

Human beings can hear from about 20 hertz to about 16 000 hertz which is a great deal of range so the piano covers like a hefty amount of that.

So yeah 88 keys and much discovery to be found.

They are annoying when things fall into them.

I've lost passport keys all sort of stuff and when I play a chord the whole body of this instrument is vibrating.

The best sound is actually kind of inside the instrument.

A hole in the guitar exists so that the sound can project.

Is it through science or from being haunted?

This in fact is a theremin and to rig this up I think I just need this which is one of two antenna that makes this work.

I'm going to put this into here ah and then powers on the back right okay so the way this instrument works is by generating two electromagnetic fields from two antennas.

So this is one antenna and this is the other down here.

This one controls volume so the further my hand gets away from this the louder the sound and this one controls pitch which is kind of neat.

I'm not a masterful theremin player but it's in that process that you generate notes and things which is beautiful.

What these antennae are measuring are essentially the electricity that our bodies are conducting.

So it's a kind of a beautiful process of measuring and proximity and things like that but anyway maybe they're also haunted.

At papa underscore gibby please what is treble?

And there's not even a question mark at the end of this question so it's really kind of quite candid.

Treble is the word that we give to the very high sounds of music.

You have bass like all those low sounds that that there's bass frequencies.

Lots of frequencies in the middle and up here this is the treble end of the sounds.

Okay here's a question from at peculiar yet real.

Do people know what a rhythm section does?

People do know what a rhythm section does.

A rhythm section is the part of the band or the part of the ensemble that plays the kind of the underlying rhythmic parts that create the body the bed of the sound over which other things can happen.

So say you're in a big band the rhythm section comprises of the drummer and the bass the guitar player and the piano player primarily and that provides the underbelly of all of those horns flutes trumpets trombones whatever you have in your big band.

The rhythm section is the part that like holds down the fort.

Here's a question that I endorse the asking of.

Explain to me dot dot dot the concept of microtones.

It does show up in popular music especially with instruments like the guitar you can bend notes on the guitar trumpets clarinets and flutes and things like this where you you have control over where you put your place the note.

An easy way to explain microtones is through a game that I often play just for fun I like playing games for fun.

How many notes can you fit between these two notes?

On the piano there are two notes between right what happens if we try and squeeze in more notes right right you go forever these are all microtones these are notes that you can't find on the piano here's a question from piss kink wow what a username bro why do people even play bass you can't even hear that shit laugh my ass off that's crazy to me okay well let's let's get let's get there's actually a bass here it's handy bass player is extremely important in music as a bass player you could you can be the drummer you can play melodies and you can also play chords so the bass is a beautiful and very important instrument in music and I'm a huge fan of the bass from at hexa chordal why do minor chords sound sad I would probably say that I think the reason why minor chords potentially sound sad is that a minor chord is actually an exact reflection of the relationships of a major chord so a major chord sounds like this this is e major one of my good friends and that is e minor another one of my good friends major chords exist in physics they exist in nature for example there's a harmonic series in your mouth if you go what you actually make here is really really quiet notes here in my mouth every note has these overtones if you yell in a chapel or a cathedral I'd recommend yelling in cathedrals in general it's just actually quite a fun thing to do but if you go in a massive room you will hear all those overtones shining back at you and you hear a major chord which is crazy a minor chord which you could say is derived from the undertone series as opposed to the overtone series it doesn't actually really exist in nature in that in that exact state in a nutshell I would say minor chords don't always sound sad but perhaps one of the reasons why they can inherently feel a little heavier the major chords is that they are the exact opposite in physics to what a major chord is it's actually not a question it's a it's a statement I think we're entering a post riff world all the riffs have been used up and there are no more riffs left to be written all new riffs are either bad or a copy of another riff I disagree personally yeah you think you can make up I think there are new riffs like let's make up one right now right I've definitely heard I've heard that before and I've heard like or something like that before perhaps no one has collided I mean let me know in the comments if you if this riff is taken and I wouldn't write a song with it but it's my ability as a riff maker to combine things that I like that maybe aren't normally put together that's what's cool that's interesting and that's what's worth doing so don't be afraid to take something you like like a riff or a chord or whatever and make it your own in an interesting way from at rod goels what makes a bass line funky that's in capital letters there what makes a bass line funky is also a little bit subjective but stable time right so just having something that's stable that you can move your body to repetition sit on this all day and then making variations on that it's not just the notes that you play or when you play the notes it's actually the duration of the notes like how long the notes are if I play all those notes long that is maybe less funky in my opinion so it's actually a mixture you see some of those notes are longer and and the control you have over the length of your notes you can go a huge distance here is another bass ready question from uh add comfortable 8467 do bassists always tune the octave down from the guitar the answer is fundamentally yes actually the bass is essentially tuned an octave down from an ordinary guitar not this five string tailor but this this is a six-string tailor that i have just stowed down here e a d g e and e these four notes here are the same as these on this bass guitar here okay this is a drum question so i'm going to answer it here at this drum kit what are your favorite tricks to keep your drum tracks interesting and or evolving well think about this all the time if you take an ordinary beat that's one of the most legendary beats of all time you can make that interesting without adding any notes or even changing any notes all i'm going to do is i'm going to nudge certain things forward and certain things backward say for example i move the snare drum backwards just a fraction this is what that sounds like and already i'm kind of like if i move the hi-hat forwards right so it's kind of sluggish falling all over itself one of the absolute pioneers of this was of course jay diller the legendary hip-hop producer from around 2000 he was just absolutely masterful at creating these kind of recipes sonic recipes for grooves that had gravity in them had grooves that have momentum in them so certain parts of the groove pulling back some parts of the groove pulling forwards all that stuff makes your drum tracks far more interesting without having to add a bunch of crazy fills this is from a core user what is four on the floor there are a few different elements here before me at the drums there's cymbals there are toms there's a snare drum but most importantly for four on the floor is a kick drum four on the floor every beat of a four four bar is filled or anchored by a kick so something like this as long as those four beats are going you'll find this you can call it up from the floor here's another question from wallow squeegee how the hell do you count odd time signatures in music in music we have we have these things called time signatures within every measure every bar you can divide that amount of space into a variety of different numbers so a lot of music is in four beats in a bar one two three four one two so if i go that's a grooving four if i were to go one two three four five six seven one two three four five six that is cool that's a bar in seven seven four you can basically divide time into any number of beats or subdivisions as you so please this is a fun question from at jp underscore bse and the question is hey music nerds i'm trying to understand the concept of polyrhythm aren't we all i've long been fascinated with the idea of polyrhythm polyrhythm just means many rhythms at once if i play three in my left hand and five in my right hand that sounds like this see so one two three four five one two three one when i was a teenager i set myself a challenge what if i could do five rhythms at the same time on the fingers of one hand so like a five-way here goes so one two three four five six one two three four five one two three four one two three one two one they happen at the same time it's funky it's fun it's cool this question comes from charles welcher how does a musical piece played with unweighted keys compare to it played with weighted keys this is a nord keyboard and this keyboard has what we call weighted keys in the sense that when i play a note the key is a little heavy it's actually it's mimicking a real piano and inside of a piano are hammers and a hammer will hit three strings per note many of us who play keyboard instruments we kind of seek that feeling there's just there's just more degrees of nuance that you can find it it's nice to be able to lean into the dimension of the sound now in this drawer here what have we here we have this lovely mini by arteria this keyboard is unweighted we say unweighted in the sense that the keys are light as a feather this can be really fun especially if you're playing like fast stuff you can whiz around it your fingers don't get so tired if i whiz around on here it just takes a bit more muscle power this is easier to fly around on but it's harder to maybe find some of the depth to maintain some of the nuance and performance with something like this here's the question what is the difference are all the notes of the c major scales the black notes are all the notes which are not in the key of c major so there are seven notes in c major and there are five notes that are not in c major they're in a completely different part of the musical key question here from vegetable oil underscore why do some chords sound better together in chord progressions than others it's a great question if i pick up this five string guitar here this is in the key of d so certain chords are when you're in d they sound nice oh you can say they sound constant in d because they have common notes so for example the chord of g major right does not sound too foreign in d major because both chords contain a d in fact this g major i played also contained an a because it had a little bit of color in it it's about the notes that carry over between chords okie doke that's everything we have time for today thanks for such amazing questions hope you learned something i sure did and i hope to see you out there very soon okay cheerio bye
