Video summary
The video introduces a fundamental perspective on building musical rhythm by breaking it down into its most basic components: sound versus silence, or playing versus resting. This binary approach simplifies complex rhythms into a form of arithmetic where every beat within a measure is treated as a slot that can be filled with either a note or a rest. The presenter explains that while Western music notation uses specific symbols like whole notes, quarter notes, and eighth notes to represent these values, the underlying logic remains consistent regardless of the subdivision level, whether it is divided by two, three, four, or even more complex numbers. By focusing on this "play or don't play" mechanic, musicians can construct any rhythm piece by piece, effectively treating music as a series of binary choices that form the foundation of all rhythmic patterns found in songs.
To facilitate this learning process, the presenter showcases a custom web application called Rhythm Arithmetic, which serves as an interactive tool for practicing and internalizing these concepts. The app operates on the philosophy of "see it, hear it, become it," allowing users to tap cells to instantly generate notation while simultaneously hearing the corresponding sounds from various percussion instruments like congas, bongos, and claves. Users can customize their practice by selecting different time signatures, choosing between standard notation or binary 0/1 representations, and utilizing features like looping, metronome integration, and rhythm dictation. This digital environment removes the need to strictly follow a physical book, offering instead a dynamic space where users can experiment with merging phrases, creating poetic rhythmic structures, and adjusting complexity bridges to build unique patterns that they might not encounter in traditional rhythm books.
Beyond simple beat divisions, the application demonstrates its versatility by handling complex polyrhythms and shifting time signatures seamlessly, such as moving from common 4/4 time to more challenging meters like 5/8 or 7/8 without losing musical accuracy. The tool includes a vast library of famous rhythmic patterns, including various clave rhythms, habaneras, and funk grooves, which users can mix and match to create original compositions. Furthermore, the app is evolving to include melodic capabilities, allowing musicians to layer chords and melodies over their rhythmic foundations, effectively turning the software into a comprehensive rhythm book that provides sound, visual feedback, and creative freedom for pianists, drummers, and percussionists of all skill levels to improve their reading and internalization skills.

Hi everyone, this is Jason Zach from
Nathaniel School of Music. In this
lesson, I'm here to offer you a
perspective on how you can build musical
rhythms literally piece by piece or beat
by beat or in a you know computer or a
binary arithmetic term bit by bit so to
speak. So what we are going to first of
all look at at the very top level is
when you have music there's either sound
or no sound note or rest play or don't
play it's about it I've run out of
opposites but anyway so the logic here
is if you have a beat in a bar of four
let's say 1 2 3 4 1 2 3 4 and what just
happened I did not play at the two. So
there's a rest. 2 3 4. So we notate the
rest with the rest symbols. We notate
the notes with the note symbols. Usually
starting with the oval the the egg shade
the egg or no don't shade the egg. Egg
with the tail becoming a minim. And then
shade it becomes a crotchet or a quarter
note. Put a tail again there and becomes
a quaver and so on. So note
[clears throat] values have shapes.
rests have symbols and all that. So this
is about kind of also understanding the
western notation equivalent
for every single rhythm that music has
to offer. We might not have time to get
into topuplets and all the complex poly
rhythms out there. But yeah stay tuned
in another one we most likely will. So
just to recap to play or not to play
that is the question. So that's all we
are going to work on in this lecture.
And what can I play is governed by the
time field of the song or what I call as
the beat division system of the song
which could be divide by two, divide by
3 or divide by four, divide by five,
divide by anything. But for 90 plus% of
music, I would imagine people just
divide either by two, by three or by
four or maybe don't divide at all. uh
which is for maybe simpler songs like
nursery rhymes or chants or things like
that. Anyway, so let's assume that we
are going to divide minim 2 3 and four
and we are going to learn rhythm
notation and also we are going to look
at an app that we've built called rhythm
arithmetic.
We leave you a link in the description.
It's a web app so you just get it
practice and very soon it'll be on the
iOS store and Android as well. So, if
you'd like to practice it along with you
on your phones, why not? But right now,
it's a web app, a fully functional one,
and it's great for practicing rhythm. We
have huge books like the the
Encyclopedia of Reading Rhythms by Gary
Hess, which is one of my favorite rhythm
books. In fact, it's inspired me to make
this app because his book has literally
everything. You have the rhythm bible.
You have so many books that really push
the boundary of rhythm and all written
by great percussionists and drummers.
But if you think about it,
[clears throat] if you break it down to
a beat level or a two beat level or a
bar of four or a bar of three or a two
bar level, two bars of four or two bars
of three, it just boils down to binary
arithmetic, doesn't it? Zeros and ones,
play or don't play. So what we have in
this app is exactly that and we've
categorized it in such a way that you
can find rhythms that are very simple or
trivial for the want of a better word
and also different ways to match rhythms
together creatively. It's not just going
to be random roll the dice kind of stuff
which also exists by the way and it's
not going to be you know preached out in
a book form where you have to literally
look at the book and follow the book.
This goes completely beyond that. It's
completely up to you and what the app
thinks it should do at the time. Right?
So the approach of composing rhythm or
piecing together rhythm there are
multiple. So stay tuned till the very
end. Also get a book out. You can draw
the symbols along, practice some
notation along the way. We're also going
to train our ears. We're also going to
improve as a pianist or any instrument.
So stay tuned and yeah, before we get
started, it'll be nice if you can
consider hitting that subscribe button,
turn on the bell for regular
notifications and let's get cracking. So
this is how our app looks as it says,
see it, hear it, become it. That is the
philosophy. So most of rhythm is beat
divisions. Divide the beat by two, three
or four. Choose sound or silence for
every slot and two race to end rhythms
appear as as real notation. You can
hear, read and internalize. Okay. And
what you do is you tap a cell, it
notates instantly. Keep tapping, it adds
more. Then loop it, sing it, shape it,
and do whatever you want. So off the
top, this is where you view everything.
This is where you loop the rhythm. For
instance, now if I loop it, you'll hear
what what's being played in the
percussion cliff.
Ta ta ta.
And you have two views. Either you want
to do it with rests or with holes or you
visualize it with both, right? Uh you
can loop the rhythm, you have the
meters. Also, this app supports melody.
So you'll have a melodic mode as well as
the rhythmic mode. The rhythmic mode if
I go here has all these samples. You
have hand drums, kahon, conga, bongo,
frame drum, wood blocks and of course
claves. So if I check the clave out
basically sticks, right? So in the
bottom you'll also have rhythm dictation
where we are working out how you can tap
the rhythm, sing the rhythm, sing with
metronome and uh it'll calibrate the
room you're in and then you check how
good you are at rhythm with without any
teacher. You just have the app telling
you if you're right or wrong. So do
consider the rhythm dictation mode which
I might not have time to go over but all
the principles of the app can be
practiced with the rhythm dictation
mode. Okay. So let's start from the very
beginning. You have this option. Pick a
cell. It becomes the next beat. So first
off, I need to choose a grid. Let me
pick one bar. So in one bar, what do I
have? Right now it's given me something
at random. Let me customize it a bit
further. So I go down here
and I can pick what I want. What should
be at beat one? If you think about it,
the options that we have are only four
either 1 1
0
1 or 0 0 which is a rest. So what more
can you do if you divide by two and if
you have one beat to fill right if I
have two beats then you can kind of use
dotted notes and you can play around a
bit more but it's these same
ingredients. However, when I go to
triplets, you have the trivial triplets,
which is just play all, swing, this one,
or don't play at all. The rest, you have
the groovy options. Ta ta da ta da. You
you'll have all these the ones with the
rests. Then you have two beats trivial
and two beats groovy. Okay. To add the
quarter note triplets to the equation as
well. And semiquavers, you have a lot of
options. You have two raised to four.
That's 16 rhythmic options. So the way
we've put it in is all in all out, two
in, two out, three in, one out, and one
in, three out. Basically, right? Uh you
can also build a merged phrase using the
complexity bridge. For example, like
writing a poetic structure, poetic
rhyming structure. A b a abba or uh a a
a b maybe so or a a a c. So it gives you
something and then you can pick and
choose what rhythm you want or if you
want a rest or whatever basically.
There we go. So the so you hit build
merged phrase and this is how it uh
populates basically. So, right now I'm
on AA C. And if you hit build merge
phrase, it's hopefully going to do A B A
C. And that's exactly what happened. And
if we play this back, da da da da da da
da da da da da da da da da da da da da
da. You also have a metronome to allow
you to kind of uh count it better or you
can just adjust the volume here or turn
it all the way off. You can even do a
count off. What that means is it gives
you one bar to practice
and now you go
and so on. If you would like to
customize uh the B rhythm to be maybe
uh
this one ta da da da da da da da. Let's
see how that sounds. Let's loop it. 2 3
4 da da da da da da da da da da da da
da. What if we want to rest at the third
beat? This is where now that you've used
the complexity bridge, you can also use
it or use it in this way. You can say,
hey, in the third beat, I'd like to just
jumble it. Oh yeah, I like that. So
let's see how this sounds. 2 3 4 D.
And now I would like to change this and
see this ecosystem is divide by four,
right? I can even do divide by three and
then roll the dice on dividing by three
and maybe have a clearcut triplet there.
2 3 4 D.
And if you don't read sheet music and if
you're just a binary person, here you
go. You can just do 0 and one and the
notation adjusts itself automatically.
You can even drag the notation here. We
are we'll be working on more features to
even add melody to the equation. So do
check that out too. And it's basically
the app. It has a lot of options and lot
of ways to build a rhythm pattern. and a
lot. Once you build it, your job then
would be to count it and you can go
fully random by maybe just mixing it
with all the beat division permutations.
See, it's just giving you all sorts of
rhythms and you can pick the ones you
like. Let's say you want to you
[clears throat] want to practice or you
start like this and keep one and jumble
the rests. I I like to do that because
the first one I enjoy that rhythm and
then I [snorts] want to piece it
together with this.
That's about it really.
Let's see how it goes.
Triplets.
Look at the visualizer if you wish.
You can adjust the pulse which is the
crotchet pulse. And uh yeah, we have
support for 3x4. What's really cool is
how the app adjusts from 4x4 to 3x4 and
it's always musically accurate. See, it
moved to 5x4. Uh it moved to 68, moves
itself to 78 and moves itself to 58,
which are more complicated time
signatures. And if you don't like that,
you can hit a clear all and build your
own [clears throat] uh 58 composition
using uh whatever grid that you wish to
to use. Maybe this one can divide by
four, roll the dice
and so on. So, and then yeah, you can
build each of the beats or each of the
phrases and roll the dice uh as you
wish. 54 44 34 are there and uh we are
constantly building the app to make it
sound a bit better. We're bringing in
some famous rhythm patterns like the
song clav which you can immediately hear
and it'll sound good. Ta
ta
or the roomba clave which is tak ta
or the three against four pol uh kind of
poly rhythm or the charleston or the
sinquilo or the habanera or the thresio
or the uptown funk as it's called. So
we'll add more rhythms. But yeah, I mean
I don't think you need that many
rhythms. You need to practice rhythm. So
think of it as basically a rhythm book
in the form of an app which has sound.
That's basically it. But unlike the
books, it's giving you every single
rhythm. You can practice at your own
pace. You have support for all forms of
notation, all time signatures. You can
do your practice length. You can adjust
it however you want. It's also a melodic
app. So, uh very soon we are going to
perfect I I'll show you uh another video
maybe where we are going to show you the
playback with chords and with melodies
and it'll also allow you to arpeggiate,
jumble them and play around in a more
creative way melodically. As you can
see, we've now gone to melodic mode and
you'll hear a melody in that rhythm.
3 4.
So that's a nice melody over one bar
that you can play around with over a
chord progression. So there are a lot of
future features. Also try out the rhythm
dictation feature to see how good your
ears are. And we'll be building a mobile
app soon, but this web app is already
mobile friendly. So you could consider
uh using this and let us know what you
think in the comments or any of our
platforms. If you'd like a proper
