Se explica cómo utilizar la 'circunferencia de quintos' para comprender mejor las escalas y cómo aplicar fórmulas para convertir escalas mayores en escalas menores naturales, armónicas y melódicas. El video también destaca la importancia de la práctica y la memorización para dominar la teoría musical, sugiriendo que con el tiempo, los músicos pueden 'visualizar' las escalas en su mente, lo que facilita la interpretación y el aprendizaje de nuevas piezas.
Takeaways
- 🎼 **Identificar P signatures**: El círculo de quintas ayuda a identificar las firmas de las escalas principales y a escribir tus escalas mayores.
- ⏱️ **Mejor método**: Se prefiere el método del círculo de quintas sobre el uso de pasos enteros y semitonos para aprender las escalas.
- 🔠 **Escalares principales**: Las escalas principales se aprenden fácilmente con el círculo de quintas, empezando por la escala de C que tiene cero sostenidos ni bemoles.
- 🔄 **Movimiento armónico**: Se prefiere ir en la dirección de los bemoles porque implica bajar en quintas perfectas, un movimiento armónico fundamental.
- 📝 **Construir escalas**: Las escalas se construyen siguiendo la secuencia de letras del alfabeto y aplicando los bemoles o sostenidos correspondientes.
- 🔄 **Patrones en escalas**: Se destacan los patrones en la construcción de escalas, especialmente cómo se añaden los nuevos bemoles o sostenidos.
- 🧠 **Memorización**: Es fundamental memorizar las escalas principales rápidamente, para lo cual se sugiere escribirlas diariamente hasta que queden grabadas.
- 🔄 **Círculo de quintas**: El círculo de quintas se puede construir en ambas direcciones, aumentando o disminuyendo los sostenidos o bemoles según se va moviendo.
- 🎶 **Aplicación a escalas menores**: Las escalas menores se pueden derivar de las escalas mayores aplicando fórmulas específicas para cada tipo de escala menor.
- 📉 **Escalas menores**: Se explican tres tipos de escalas menores: natural, armónica y melódica, cada una con su propia fórmula de conversión desde la escala mayor.
Q & A
¿Qué herramienta se utiliza para identificar las firmas de escalas mayores y menores?
-Se utiliza el círculo de quintos para identificar las firmas de escalas mayores y menores, lo que ayuda a comprender y memorizar las escalas de manera eficiente.
¿Cómo se determina la escala mayor de C?
-La escala mayor de C se determina sin sostenidos ni bemoles, y se sigue el orden de las letras del alfabeto sin repetir ninguna letra consecutivamente.
¿Cuál es la forma más eficiente de aprender las escalas mayores según el guion?
-La forma más eficiente de aprender las escalas mayores es a través del círculo de quintos, en lugar de memorizar el patrón de sostenidos y bemoles.
¿Cómo se añade el primer bemol en la escala mayor de F?
-El primer bemol se añade como el cuarto sonido en la escala mayor de F, que es B♭, siguiendo el principio de que el nuevo bemol siempre es el cuarto sonido de la escala.
¿Cuál es la relación entre los sostenidos y bemoles en el círculo de quintos?
-En el círculo de quintos, los sostenidos y bemoles se introducen en un patrón específico, donde los sostenidos se agregan al ir hacia la derecha y los bemoles se agregan al ir hacia la izquierda.
¿Cómo se determina la quinta nota en la escala mayor de D♭?
-La quinta nota en la escala mayor de D♭ es A♭, ya que sigue el patrón de sostenidos y bemoles determinado por el círculo de quintos.
¿Qué es la forma de menor natural y cómo se obtiene a partir de una escala mayor?
-La forma de menor natural se obtiene al bajar la tercera, sexta y séptima notas de una escala mayor media semitone.
¿Cuál es la diferencia entre la escala menor natural y la escala menor armónica?
-La escala menor armónica difiere de la natural en que también requiere bajar la sexta nota, pero no la séptima.
¿Cómo se determina la escala menor melódica ascendente y descendente?
-La escala menor melódica ascendente se determina al bajar solo la tercera nota de la escala mayor, mientras que la descendente sigue el mismo patrón que la menor natural, bajando la tercera, sexta y séptima notas.
¿Por qué es importante memorizar las escalas de manera correcta?
-Es importante memorizar las escalas de manera correcta para evitar la formación de malas hábitos y para que el cerebro pueda asociar rápidamente las notas con las escalas, mejorando la capacidad de leer y tocar música.
Outlines
🎼 Introducción a las escalas mayores y la circunferencia de quintos
El primer párrafo introduce la importancia de las escalas mayores y cómo la circunferencia de quintos puede ayudar a identificar las firmas de las escalas y a escribir estas escalas. Se enfatiza en la eficiencia del método y se compara con la técnica tradicional de pasos enteros y semitonos. Se explica que la escala mayor de C, que no tiene sostenidos ni bemoles, se puede escribir simplemente siguiendo el abecedario sin repetir letras. Además, se introduce el concepto de cómo se añaden los nuevos accidentales en las escalas, siempre como el cuarto tono de la escala, como en el caso de la escala de F mayor que introduce un bemol en la cuarta posición.
🎹 Escalas mayores y su identificación de accidentales
Este párrafo profundiza en cómo se identifican las escalas mayores a través de los accidentales, mostrando ejemplos como la escala de B flat mayor con dos bemoles y la de E flat mayor con tres. Se destaca la importancia de reconocer patrones y seguidamente se explica cómo se añaden los nuevos bemoles en la cuarta posición de la escala. Se menciona la relación entre las escalas y cómo el nuevo bemol en una escala da lugar al siguiente bemol en la siguiente escala, como el D flat mayor que introduce un G flat.
🎶 Expansión de la circunferencia de quintos y su influencia en las escalas
El tercer párrafo continúa explorando la circunferencia de quintos, esta vez en la dirección de los sostenidos. Se describe cómo se añaden los sostenidos a las escalas, siguiendo siempre la fórmula del nuevo sostenido que es una letra antes de la nota de la escala. Se mencionan ejemplos como la escala de G mayor con un sostenido y la de D mayor con dos. Además, se discute la utilidad de la circunferencia de quintos para memorizar y entender la relación entre las escalas y los accidentales, y se sugiere prácticas para internalizar esta información.
📜 Memorización de escalas mayores y su importancia
Este párrafo aboga por la práctica de escribir las escalas mayores repetidamente para que se conviertan en un reflejo instintivo. Se comparte una anécdota personal sobre cómo la escritura diaria de escalas en clase ayudó a memorizarlas. Se enfatiza la importancia de la memorización para el aprendizaje de la música y cómo la capacidad de visualizar mentalmente las escalas mejora con la práctica. Además, se introduce la idea de que la escritura correcta es fundamental para evitar la formación de hábitos incorrectos.
🛠 Conversión de escalas mayores a escalas menores
El quinto párrafo introduce el concepto de las escalas menores y cómo se derivan de las escalas mayores utilizando fórmulas específicas. Se explican los tres tipos de escalas menores: natural, armónica y melódica, y se proporcionan las fórmulas correspondientes para cada una. Se resalta la importancia de recordar desde qué escala se parte y a cuál se llega para aplicar correctamente las fórmulas. Se ejemplifica la conversión de la escala mayor de D a la escala menor natural, cambiando la tercera, sexta y séptima notas.
🎵 Detalles sobre las escalas menores armónicas y melódicas
Este párrafo profundiza en las escalas menores armónica y melódica. Para la armónica, se menciona que solo se baja la tercera nota, mientras que para la melódica, la versión ascendente solo requiere bajar la tercera nota, y la descendente sigue la misma fórmula que la natural menor. Se discuten las implicaciones de la notación musical y la historia de la impresión musical en la formación de estas escalas y se advierte sobre no confundir las fórmulas al convertir escalas. Se ejemplifica la escala de G flat mayor y su conversión a la escala melódica ascendente y descendente.

Highlights
Circle of fifths is a tool for identifying key signatures and writing major scales.
The most efficient way to learn major scales is by mastering the circle of fifths.
The key of C has zero sharps and flats, making it a straightforward starting point.
Major scales are built by following the pattern of whole and half steps.
The fourth note in a major scale determines the flat or sharp in the key signature.
Patterns in the circle of fifths can help quickly identify key signatures.
The circle of fifths can be used to find both sharp and flat key signatures.
Writing out major scales repeatedly helps to memorize them effectively.
Memorizing scales can lead to a 'photographic memory' for music theory.
The circle of fifths can be used to derive minor scales from major scales.
There are three types of minor scales: natural, harmonic, and melodic.
Natural minor scales are derived from major scales by lowering the third, sixth, and seventh notes.
Harmonic minor scales are derived by lowering the third and sixth notes of a major scale.
Melodic minor scales have different formulas for ascending and descending.
Enharmonic spellings are important for understanding the structure of scales.
The circle of fifths can be used to understand the relationship between sharps and flats.
Memorizing scales using the circle of fifths can improve sight-reading and music theory understanding.
The circle of fifths can be visualized as a tattoo for easy reference, highlighting its importance.
The Guidonian hand is another historical method for teaching music theory.
Double flats and double sharps simplify music notation and printing.

all right so starting with the circle of
this this is going to help you with
identifying P signatures and writing
your major scales and using the major
scale is probably the most efficient way
to to figure out just about everything
so one of the goals is to get it so that
you can name all your major scales like
like lightning and you got it down paack
so this is one one way there's another
different methods you can use and this
is the method that I think is the most
efficient one of the methods that I
don't think is the most efficient is
that whole the idea of using whole step
whole step half step whole step whole
step whole step half step it works it's
just really slow and what I'm trying to
do is give you guys the the most
efficient quickest way that's going to
help you learn this stuff so in the
circle of fits when we talk about the
key of C this is we're all talking only
major scales right here the key of C has
zero Sharps zero
Flats so the way it works for when we're
going to always have the letters in
order for a scale so if we have a C
scale you start on a c and then you go
through the alphabet d e f g a b and
then you loop around to C and you then
say well I know I have these letters
because it's always going to have the
letters you never have the same letter
more than once consecutively you'll have
it at the beginning at the end but
you'll never have like c d d g you'll
never have that you'll have all the
letters in order and then you say well
it's got zero Sharps zero Flats I'm done
that's your C major scale because that's
zero sharp zero Flats now when we go and
and some some people will do the the
sharp Direction going this way and it'll
be inverted I like this way because this
is down in perfect fifths and since
going down a fifth is a fundamental
harmonic motion I like to do it in this
direction this major scale the F major
scale has one accidental and this is the
flat Direction so we're going in the
direction of
flats right
Flats one flat so in the F major scale
we've got one flat now we know we can
the letters and we know an F major scale
is going to have an f g a b c d e f and
one of the notes is going to have a
flat the flat that gets
added is
always the fourth note in the
scale so if you write out the letters
like this the fourth one is always the
new flat so in this case this
is the
flat so I add the flat we're good to go
that is your F major
scale so our next major scale is a B
flat major scale so we know we have b c
d e f g a b we know that the B is flat
and here we got to make sure we do the
the beginning note and the ending note
right CU they're the same and we have
the new
flat and as I said the new flat is
always the fourth note of the scale 1 2
3
4 means it's E flat so E
flat so the the key signature of B flat
major has two Flats E flat is our new
flat now you're going to notice patterns
here so keep your eyes open for patterns
right and for for those of you that know
this sometimes having a methodology like
this will help you if you're going to
try to teach someone else you want to
have a way that you can explain it
that's really clear you want a principle
a method that allows you to think about
it so when we go to our EF flat major
scale it's going to have three
Flats you can see again one two three
guess how many in a flat four right and
if we write out e f g a b c d e we know
that we have our our first flat again
the flats that we introduced they don't
go away so we have our B flat we have
our E flat we add it both for the top
and the bottom of the scale and our new
flat is the fourth not 1 2 3 4 e f g a
it's a flat now you'll notice that the
new flat is always the next scale as
well
right so without even counting you will
know that in your a flat scale the new
flat is d flat and in your d flat major
scale the new flat will be g
flat so let's kind of erase
this and just do those scales right so a
flat major scale we know we write the
letters first a b c d e f G A it's got
four flats the first flat is B the
second flat right first flat is B second
flat is e second flat second
flat uh is our a flat we add two because
it's the beginning and the end and our
new flat 1 2 3 4 is the d flat and now
we have our D our our a flat major scale
spelled
out we go on to d flat same principle d
d e f g a b c
d so three
flat
there we know that a d flat major scale
has five
flats the new flat is the g flat and if
we just going to fill it in five flats
right so B flat second flat E
flat a flat
d
flat and the new one is a g
flat and you want to get to the point
where you know these
scales off the top of your head so I can
say d flat major scale and you go d flat
E flat F G flat A flat B flat c d flat
got
it and then I can ask you things like
what's the fifth note in the D flat
major scale and you go well it's a flat
because I know my scale and I could say
who that's great what is the third note
in an E flat major scale G you know it
that
quickly that comes in part by writing
out your major scales just
until until you have like a photograph
in your mind so
I'm I'll tell a quick little story here
11th grade I had a friend played guitar
and he knew all his scales and I did we
were an American history class together
and
we looked like we were taking
notes all class what we were really
doing were writing notes and he was
teaching me the scales and I would write
out my major scales every day in
American history class and then
afterwards I go to the band room and I
play it on my saxophone and I close my
eyes now and I see staff paper and I can
see the scales in my mind and then I
work out Triads and then seventh courts
and it's now it's the only thing I have
a photographic memory for but it's
because I wrote it out for an entire
year every day and now it's it's just in
my
head it's pretty pretty
cool now my my knowledge of American
history for a long time was totally
embarrassing like if you go on those
late night shows where they interviewed
people on the street they said wanted to
say something really stupid and you're
like oh my goodness that would have been
me i' I've tried to fix that a little
bit at least but write out your major
scales over and over until you start
feeling like they're like locked in your
brain so we're going to we're going to
go the other direction now for a little
bit I know we didn't finish with g flat
yet okay
um but we go in this direction we're
going the sharp Direction so this is
Sharps so a G Major scale has one Sharp
so we do the same thing we write out our
letters g a b c d e f g and again we're
just using our alphabet right A B C D E
F G but starting on whichever one and
we're just using those
letters so we got one sharp what sharp
is it what's the principle what's the
formula the formula is always the new
sharp is one letter before the note of
the scale so if we're talking about a G
Major
scale what's the letter that comes
before g f so F
sharp we could also say 1 2 3 4 five six
7even the seventh note but instead of
counting 1 2 3 4 5 6 7even it's always
easier to go one back so the new sharp
is FP D major
is going to have two sharps a major
three Sharps E major four sharps B major
five Sharps F sharp six
Sharps we're get I'm explain this this
inharmonic P right here in a
second so when we come for a D major
scale d e f g a b c d we have our first
chart and our new sharp our second sharp
which is always one back from d d one
back
C the other aspect of that helps you
with this whole circle of fif is trying
to figure out memorize how this this
circle this
little this little works I always
thought like I don't I don't have any
any tattoos but there's two tattoos that
I thought would be cool to get as a
musician one is the circle of fifths
just like oh yeah I got my scales
down the other was um the guidonian hand
which if you take to study music music
history or oral skills there was a a
method of sight singing of like soulfish
Doras latio and it was used to like
teach singers like if you didn't know
the music the the choir director would
just point to like a certain part of his
hand and be like that's the note you
should be singing and like you could do
the whole Melody just on your hand
I thought that would be cool just be
like tell people to Melody so circle of
fifths we're going this way we're just I
call it down in fifths right so if we go
count backwards from from C right we're
going c b a g f
so let me write it this way C backwards
b a g f
down to fifth 1 2 3 4
5 and when we going down to fifth again
we're always going down a perfect fifth
which means we have to include that flat
that got
introduced so we're going always going
down five but we're we're including the
flat that we added in each
scale this direction we're going up in
fifths so if you're going
counterclockwise you can just go C d e f
g up a fifth g a b c d up a fifth and
again we're going to include whatever
Sharps get introduced but but you don't
really start getting that until you go
from B to F sharp because you go b c d e
f but we've introduced F long ago and
you can't forget about
it so that's how you can kind of
reconstruct the circle of this so as
you're like do working on this at home
practice writing the circle of fist then
practice writing out the scales you do
that enough times it'll it'll become a
photograph in your head got to do it
correctly though you can't do it wrong
because then you get a wrong photograph
in your head and then you know it's like
habits right there's good habits there's
bad habits how do you make a habit you
do it over and over so you do the wrong
thing over and over bad habit you do the
good the good thing over and over good
habit so you want to write it out
correctly every time so that your brain
starts being like photograph I got it
the
correct so with
that we're basically figuring out how
we're doing all our major
scales you'll notice here that I put a
slash here and we actually have one more
C
flat if I were to go the sharp Direction
e v FP
if I go one
more it's C so C is going to
have seven Sharps and we have major
scales up to seven flats and up to seven
Sharps
so all the scales we can have we can
have a C major scale g
d a e b f and c Shar and this is
zero sharps or flats one sharp 2 3 4 5 6
seven and when we have go the flat
direction we got one
flat Two Flats three Flats four flats
five flats six
Flats seven Flats right so C and I'll
and I'll even move this over here so C
I'll put C in the middle it's the one
that has zero and then number of
accidentals this is the sharp
side this is the flat
side and you got all of those so that's
why we have these slashes here and and
harmonic and when I say write out all
your major
scales there's 15 of them you it's not
like oh there's 12 notes on the piano
well yeah but we we have these other we
go up to 7 Sharps and flat so we
actually have to know the N harmonics as
well okay so that's how we work the
major
scales you want to get comfort with that
now as if your brain isn't already like
filled with that minor scales and what I
like to do is I like to use major scales
to give me my minor scales I like to
apply a formula to a major scale to
convert it into a minor scale there's
other
methods and that's okay this is just the
one that I think is the the fastest the
most
efficient now there's three different
types of minor scales okay there is
natural
minor there is harmonic
minor and there is
melodic minor so there's three different
forms
or types of minor scales and each one
requires a different formula and again
it's really important to remember what
you're going from and what you're going
to because if you mix that up and apply
the formula to the wrong thing you'll
come up with the wrong answer which is
no surprise so I'm always assuming I'm
starting with a major scale so with
natural Miner if I
start with a major scale
and I want to convert it into natural
minor I
lower the third note of the
scale the sixth note and the seventh
note by a half step I'll say that again
I'll take a major scale I lower the
third note the sixth note and the
seventh note and Presto I've got myself
a natural minor scale so let's start
let's start relatively simple let's take
our D major
scale we look at our circle of fist D
major scale has two sharps they are F
and CP so I write out my D major scale d
e f g a b c
d I lower the third note I'm going to
number it here so you can see
it I lower the third note a half step so
the fshp becomes an F
natural I lower the six
note so the B becomes a B
flat and I lower the seventh note a half
step so the
C becomes a c
natural taada we now have our natural
minor scale by applying this formula
lower the third the sixth and the
seventh we can convert a major scale to
a natural minor
scale I'm going to tell you a little bit
about some of the other things later but
right now I don't want to overwhelm you
I'm going just want to do one step at a
time so we're just going to worry about
this method
now for harmonic minor it's a different
formula again we're going to start with
the major scale but for this one we only
need to lower the Third
and lower the
six and we will get our scale now this
method will have some problems when we
start dealing with the key signatures
you'll notice that I'm writing
everything here as separate pitches
without a key signature and I would
that's how I recommend you start doing
it so you can just memorize the names so
major scales tie them to a key signature
minor scales let's just think of them as
derivatives from a major scale for
now harmonic let's pick another one
let's pick a a flat one let's go with E
flat major so E flat major we've got
three Flats they are B flat E flat and a
flat so I will write my E flat major
scale E flat F G A flat B flat C D
I write the octave of E flat there and
then I follow the formula the third Note
1 2 3 gets lower to half
step so G becomes G flat and the sixth
note E flat F now g flat k flat B flat C
the C becomes a C
flat and I have that scale right so
let's let me just play here was my E
flat major scale
now my E flat harmonic
[Music]
minor and that's what it would sound
like but Dr Brock C flat is the same
thing as B natural why can't I just
write B
natural because you can only have one of
the letter you have to have all the
letters in a row remember how we were
developing the whole scales we wrote the
letters and then applied it you can't
have a B flat and a be natural side by
side in the scale you have to have each
letter represented which is why it's
important that we know about these
enharmonic
spellings and when you first start
learning music it might seem like wow
it's just more complicated by they
having you know F flat and e sharp and
why would they do that it's just doesn't
make any sense it does it's actually
easier because when you start dealing
with the
scales you then have a unit you have
this formula and structure so when
you're memorizing music and learning
music if you can just be like apply
formula in your head you're going to
learn music faster you're going to site
music
better again like learning an an entire
memorizing a conero it's not easy what
makes it easy is by knowing these
formulas so when I'm memorizing a piece
on my saxophone I I often will analyze
it theoretically and say ah so this is a
a flat major scale going down and then
this madic minor scale going up and I
don't need to memorize all the different
individual notes I'm just memorizing
this scale followed by this scale and so
instead of learning all the little
pieces I'm learning by chunks and the
human mind works a lot faster when you
learn in chunks so that's why it's
important to be clear on the enharmonic
spellings all right lastly we get to
melodic minor now melodic minor is the
trickiest because it has two versions it
has an
[Music]
ascending which means as you go up the
scale and a
descending which means as you go down
the scale it's a different scale so it's
one scale going up and another scale
going
down so for the ascending
version again we'll start with our major
scale we apply a formula the formula is
lower the third a half step that's it so
you can kind of see like what makes all
of them minor what makes minor minor the
lower third that's what does it
everything else is just different
variant right so as you're memorizing
this you'll always just say again you're
looking for principles and commonalities
here all of them lower the third and
then you say oh harmonic I also have to
lower the six and natural it's that six
and the seven so we're only just adding
one one thing if we're going this way as
we're looking at it so let's take
another
scale um let's let's make it a
challenging one let's go with our g flat
major scale g flat major has
six six Flats right here so we will
write out g a b c d e f g we'll apply
our Flats first flat b e a d our
G's and our C flat that's a lot of flats
right everything except
F and we lower the third a half step so
g flat A flat B flat well guess what
they call that b double flat so we have
double flats and double sharps and those
are going to help us again you're you
might say Dr Relic why would they do
that it makes it makes it so much more
complicated be double flat it's just the
same thing as an a natural why not just
it's
because now we have to have two a's in a
row and it's not only for the how you're
going to think it conceptually but if we
go back historically and think about how
music was being
printed it's a lot easier to say here's
a here's a a key signature and we're
just going to put them all in order as
opposed to if you have a one's an A flat
and one's an a natural you're going to
have to add accidentals into the actual
music and originally music is being
printed by wood block
carving so the less you need to carve
wood the better right and then if you
need to change it it's like oh got to
carve another wood block here right
so the ease of music notation and
printing is another reason why we have
these because it
allows things to be adjusted like you
might say all these notes are flat and
if I add one I'll just have to add that
one flat and if i' have all these notes
in the same row I have to change them
back what kind of a it is and I have to
add lots of aent as opposed to just
one so there we have it now we got our
ascending molic
minor
descending is the same exact formula as
natural minor
so you take the major scale you apply
the lowered third lowered six lowered
seven and you then have the descending
natural minor word of warning you don't
take your ascending melodic minor lower
the third the sixth and the seventh
because if you were to do that your b
double flat now would be a b triple flat
and that does not exist there are no
triple Flats there are triple Sharps so
again your formula is always from a
major scale to convert so you go up G
flat A flat B flat C flat d flat E flat
F G flat and on the way down it would be
F
flat e double
flat because again this is my seven and
six d flat C flat the bble flat stays on
the way up and down again that's what's
fun to minor a flat and G flat all right
