Shell Voicings on Piano: Why C7 and F#7 Are the Same Two Keys (Tritone Substitution)
Watch on YouTubeVideo summary
Bu ders, piyano armonjisinde kullanılan "shell voicings" (kabuk seslendirmeler) tekniğini ve özellikle dominant yedili akorların triton altı yerine kullanımı üzerine odaklanmaktadır. Konu, tüm akor notlarını çalmak yerine sadece akorun en önemli tonlarını seçerek daha az nota ile zengin bir tını elde etmeyi hedefler. Bu yöntemde genellikle akorun üçüncüsü ve yedinci notası öne çıkarılır; bu iki nota arası triton (tritone) intervalı oluşturur ve piyanistlere hem farklı inversions arasında geçiş yapmayı kolaylaştırır hem de solmaktan gelen melodik hatları destekler. Dersin temel argümanı, bir dominant yedili akorun üçüncüsü ve yedincisi ile beşinci notasını çalmak yerine sadece üçüncü ve yedinci notaları kullanarak daha esnek bir yapı kurmak ve bu yapı üzerinden besteleme veya ritim kalıpları oluşturmak üzerine kuruludur.
Örnek olarak C7 akoru incelenirken, sol el kök nota (C) çalarken sağ elde sadece E ve Bb notalarının çalınması gösterilir; burada beşinci nota (G) opsiyonel hale gelir. Bu iki nota arasındaki triton ilişkisi, aynı seslendirmenin hem C7 hem de F#7 (veya Gb7) akorları temsil edebileceği fikrini doğurur. Bu durum, müzikte kullanılan on iki dominant yedili akordan altısının birbirinin triton altı yerine kullanılabileceği anlamına gelir; yani piyanist sadece altı farklı akor çiftini ezberleyerek tüm tonaliteyi kapsayan bir sistem kurabilir. Böylece F#7 akoru çalmak istendiğinde, C7 akorunun aynı nota yapısını (E ve Bb) basmak suretiyle kullanmak mümkündür; bu sayede solmaktan gelen kök notası değişse bile sağ eldeki seslendirme şekli korunarak akılda kalıcılık sağlanır.
Dersin ikinci yarısında, bu shell yapıları üzerine ritmik çeşitlilik katılarak Charleston ritmi ve el bağımsızlığı egzersizleri uygulanır. Sol elde kök ve beşinci notaları Charleston ritmiyle çalarken, sağ elde shell yapısı üzerinde farklı zamanlamalarla (örneğin iki ve dört vuruşlarında) veya yarı nota değerlerinde çalışılır. Ayrıca bu yapılar üzerinden dokuzuncu, düz on birli gibi uzantı notaları eklenerek akor rengi değiştirilebilir; örneğin C7 akoru üzerine bir dokuzuncu eklendiğinde el tutuşu neredeyse aynı kalır ancak armoni zenginleşir. Bu teknikler gitaristler ve diğer çalgıçılar tarafından da benzer şekilde "kabuk" üzerine ekstra notalar ekleyerek kullanılırken, piyanoda ise pedal kullanarak bu kısa melodik dökümleri (cascade) sürebilirsiniz.
Sonuç olarak, bu ders hem armonik teorideki triton altı yerine mantığını hem de pratikte shell voicings ile ritim ve besteleme becerilerini birleştirerek sunar. Öğrencilerden tüm beşler çemberi boyunca bu akor çiftlerini ve ritmik kalıpları çalışarak el koordinasyonunu geliştirmeleri istenir. Ders, sadece teknik bir egzersiz değil aynı zamanda caz ve blues müziğinde besteleme serbestliği kazandıran bir altyapı sunar; çünkü shell yapıları sayesinde besteci veya solist, temel akor yapısını korurken melodik özgürlük içinde hareket edebilir. Tüm bu içerikler Patreon sayfasında bulunan uygulama ve çalışma kılavuzlarıyla desteklenerek, öğrencilerin her tonalitede bu teknikleri uygulamasına olanak tanır.

Hi everyone, this is Jason Zach from
Nathaniel School of Music. In this
lesson, we are going to focus on chords,
but not the regular way we play chords
with, you know, inversions to help you
go from, let's say, C to F major or C7th
to F major or something else, you know,
which involves good voice leading, but
with the same number of notes for the
chord. So, if it's a triad, it'll have
three. If it's a seventh chord, it would
have four notes. So example C major has
three notes.
C7th has four notes. C, E, G, B flat.
[music] Now when we use it, we can
either play C major like this. Root
position, first inversion, second
inversion. While C7th, root position,
first inversion, second inversion, and
third inversion. In this lesson, we're
going to just focus on the idea of
voicing using shells. Shells are
basically smaller note choices. You will
not play all the notes of the chord 1 3
5 7 9 level. Instead, you figure out the
notes that matter and the notes that are
maybe spicy or important and also the
notes that provide better voice leading
and actually glide well from chord to
chord or from harmony to harmony. The
other advantage of learning shell
voicings is so that you can improvise.
You can kind of stay on a shell.
[music]
you kind of stay on that shell and then
play within the vicinity of that shell.
So in this lesson we are going to just
look at a voicing which has two notes
namely the third and the seventh and
we'll pick just one chord for the lesson
the dominant seventh chord. A dominant
seventh chord will be the one the three
the five [music] and the seven flat or
the minor 7th. So it's basically a major
chord [music] with a minor 7th interval
added to it. So why that helps is if you
say major chord plus B flat, you can go
to the same major chord in any inversion
[music]
E G C and then add the B flat and then G
[music] C E and then add the same old B
flat and then C E G and you play the B
flat either upstairs or
downstairs [music]
below the triad. Okay, so that was about
playing the entire chord with all the
four notes. So now over to shell voicing
or you know the pick and choose kind of
voicings where we take the important
notes, keep that as a shell and then
improvise, build rhythm patterns, build
licks, build more advanced chords like
the nines, sharp nines, 11s and so on
and learn a lot of other rhythmic
principles along the way. That's exactly
what we are going to do in this entire
lesson from start to finish. It's going
to be about harmony. It's going to be
about improvisation. It's going to be
about basic rhythm patterns that you'll
need for blues and jazz. A few fun
exercises that you can do with your body
like clapping and snapping at certain
beats and a good workout in general. And
to supplement this lesson, you'll have a
practice study guide waiting for you on
our Patreon with all the exercises and
the notations. You'll also have my
handwritten notes. And you'll also have
an app in our Patreon page itself for
exclusive Patreon subscribers to play
this same exercise and do all the
variations, not just on the key I'm
teaching you in this lesson, on every
single key. Okay? So in this lesson,
we'll probably pick C and then move
forward from there. But we are going to
cover almost every movement. We'll move
around the entire circle of fifths. So
it won't really matter much. Okay. So
before we get started, do get your
keyboards out, play along with me, and
stay tuned till the very end. You'll
learn a lot. And there's also a
subscribe button somewhere there. If you
like what we do, do consider hitting the
subscribe button and turn on the bell
for regular notifications. Okay, so
let's get cracking. So let's start with
the C7th chord. You can start off by
playing the root in the left hand,
[music] the C. And in the right hand,
you don't need to play C again because
it's already in the left, right? So play
C here. [music] And what's left? You
have E, G, B flat. These are the
remaining notes. So you already see a
voicing of a dominant seventh chord
being any root, upper major third.
[music] and you play a diminished chord.
This could free up your mind. So C
diminished could be looked at as in E
diminished/ C. [music]
So that E diminished can be voiced in
three shapes.
Root position, first inversion, and
second inversion.
However, an even more simpler shell to
practice would be to knock off the fifth
as well. [music]
Play the fifth in the left hand if you
want later or anyway it becomes optional
and in the right hand you play the third
[music] as well as the seventh.
So the third and seventh form a trionee
interval. A tritone is basically perfect
fifth minus one or a perfect fourth +
one. And tritones work in pairs. So E to
B flat could also be inverted and you
end up generating [music] the other
trionee which is B flat to E
B flat B flat E
B flat B flat E. So this can help you
with the inversions or two shells for
basically the same chord. And we later
on look at the concept of tritones and
tritone substitutions where the same
shell could be used for two chords, two
dominant seventh chords. So again to
recap, in the left hand you play C,
[music] the right hand you play E and B
flat. And optionally in the left hand
you can add on with a G.
Start off [music] with this.
1 2 3 4 1 [music] 2 3 4 1 2 3 4 1 So,
semi briefs in the right hand, [music]
minim. [clears throat]
You can also then consider the inversion
[music]
1 2 a 3 4 1 2 a 3 4. [music] So the two
shells are 3 seven flat for the dominant
7th and [music]
7 flat 3.
Repeat 3 7 flat
and then [music] seven flat three.
So keeping this shell
[music]
you can improvise.
[music]
You can also [music] groove or add some
rhythm to the shell
or [music] maybe some slides.
>> [music]
[music]
>> Okay. And the thing about the C7 shell,
C's [music] third is E. C7 flat is B
flat. But if you take C tritone, the
chord itself, what is C tritone? G flat
also known as F sharp. So if you go to
the trionee either C going to F sharp or
G flat you can retain the same shell
three and seven flat it's just going to
be called F sharp 7th [music] because F
sharp or G flat 7th is in the bass. So
C7th is also F sharp 7th if you keep the
same shell and if you invert the shell
7 flat 3
it still holds [music] good for F sharp
because it's the same notes C's third is
F sharp 7 flat or C is seven flat is F
sharp's third or major third right so
just so you know with one shell you get
two dominant seventh chords so using
this principle with 12 dominant seventh
chords, you're going to have two tritone
pairs each, right? So, you'll just have
to study six dominant seventh chords, so
to speak, cuz each one would be a tronee
substitution of each other. So, C to
[music] F sharp.
Then you'll have F to B. [music]
Then you'll have B flat to its trionee
[music] E B flat E B flat E. Then what
[music] else? So you'll have E flat its
trionee A
E A E flat A E flat 7th A. Right? So E
flat 7 trionee is A or A's trionee is E
flat 7th and then you'll have a flat 7th
[music] whose tritone would be D7
A flat 7th. [music]
So you'll get six trionee pairs.
Let's drift [music] forward to the D
flat.
Its trionee sub will be G7th. [music]
And after D flat comes F sharp. And
what's F sharp 7 trione? You guessed it,
C7th. [music]
So all you have to learn is basically
the pairs and then learn six of them.
And the shell in the right hand will
either be 3 7 or 73. So let's give this
a spin by actually moving in the circle.
The circle of what? The circle of
fifths. The most famous circle of music
arguably. So you move the circle of
fifths ideally counterclockwise because
the chords resolve to each other. You
can get 5:1 cadences also known as
authentic or perfect cadences. You would
also get two 51 progressions which are
used a lot in jazz. All of this will be
circle of fifths counterclockwise. So
you'll have a D minor 7th, G7th, and C
moving counterclockwise. But in this
case, we'll just do it with dominant 7th
chords. So you take C at the 12:00,
[music]
you go down a step counterclockwise,
[music] you get F7th,
and then you go down a step, [music]
you'll get B flat 7th. You go down a
step, you'll get a [music] E flat 7th.
Then you go down a step, you'll get A
flat, D flat, F sharp, [music] B, E, A,
D, G, C. If you start with maybe a seven
flat three voicing of C, you're just
going to practice moving chromatically
[music]
like this
to get those tronee pairs or trionee
intervals.
[music]
And the left hand will just go around
the circle of fifths with those roots.
C, [music] F, B flat, E flat, A flat, D
flat, [music]
F sharp, B, E, A, D, G, C. [music] And
if you started on B flat E, you would
end again on B [music] flat E. And you
have two drills to work on. You'll have
to do starting with the seven flat
[music] 3. You can also start with three
seven flat. Maybe I should have started
with that in the first place. But
anyway, so E B flat [music] and again
chromatically pretty much in the right
hand.
[music]
E flat A flat D flat F sharp B [music]
A
D G C 2 3 4 1 2 3. So shells are very
useful while doing a lot of things while
maybe improvising
[music]
on this you can build. So your hands are
already playing two very spicy or
authentic notes to the chord. And the
other nice thing about shells for
improvising and chord building is the
tensions or the exciting notes are just
or the extensions are just one step
away. If you play [music] C7th like
this, all you have to do to generate
maybe a ninth [music]
would be to play a C sharp there. Or
maybe I can widen it with the three
seven flat. Play the ninth either here.
[music]
It's a nine flat by the way. I can even
play a normal nine or I can even play a
sharp nine
and it's the same shell. So your hand
grip or your hand hold is almost the
same. So this is a technique actually
all instrumentalists which play chords
especially guitar players and other
stringed instruments follow. They
basically get onto a shell shape and
just add an extra note. And that extra
note could be either down or it could be
up, you know, and if it clashes, for
example, you don't want to play the
sharp nine like that cuz there's a
semmit tone clash here. But if you play
it there, it works. So the gaps between
the notes are very important for the
overall sound.
You can [music] even change the shell.
Instead of making the seven flat,
you can add a sharp five. [music]
It's still a C7th, but now it's becoming
a bit more like an altered chord, so to
speak. So, one note away, and you get a
very sophisticated sound with the
shells. And like I said, it's very easy
to improvise with them. And another
useful thing, of course, for shells
would be to play licks and short
phrases. Maybe I'll do another lesson on
this later, but just to give you a quick
idea,
you know where I stole this song from,
right?
[music]
So, you see where I'm going from there.
You take popular songs, phrases from
those songs and you can kind of make
them your own and just kind of get
multiple tiny ideas from different
pieces of music and the shells will keep
that harmony going. So now moving
forward, let's learn a few rhythm
patterns all based on a very simple
rhythm system which I've talked about a
few times in my blues lessons. Do check
out some of the other lessons as well.
You can access them in playlists. You
can also access them on our free
tutorials website which is basically an
archive of all the stuff that we've
covered on YouTube. So this rhythm is
the Charleston rhythm. The Charleston
rhythm will generally swing and it's a
two hit phrase and the distance between
the two hits is a dotted quarter note or
one and a half counts. So it'll be swung
1 and 2 and 3 and 4 and 1 and 2 and 1
and 2 and 3 and four and 1 and two. So,
so you could just take a C7th one and
two [music] and
and now go down the circle
[music] maybe with both hands where you
can play the root of the chord in the
left
and I'll give you more rhythm patterns
in the left for [music] sure.
So let's do the other Charleston which
is just displacing by one subbeat. So
it'll be 1 and 2 3 4 1 and 3 4 1 and 2 3
4 1 and 2 3 4 That's basically
4 1 and 2. And I'm only [music] playing
the shells in the right hand. 1 and 2
and 4 1 and 2 and 3 4 1 and 2 and
[music] 4 1 and 2. You can even combine
the two Charleston by going maybe the
off one
[music]
and then the on one one off on
off
on on or do on off
on [music]
off
but they are separated by that [music]
dotted half note, a quarter note.
[music]
So
you could do the same drill going down
the circle of fifths with basically the
Charleston A, Charleston B, which is at
the displaced one, and then combining
and then going down the circle of
fifths. So let's try and bring in
exercises for both of our hands. Now
what if the left hand holds the
Charleston and the right hand kind of
increments. So left hand can do maybe
root and fifth in Charleston
1 and 2 and the right hand can start
with semi briefs. 1 and 2 and 3 and
[music] four and 1 and two. One and two.
Just keep it simple. One and [music] two
and three and four and one and two and
four and one. Then we can perhaps go to
minmss [music]
1 and 2 and three. So you're striking at
the one and three while here you
continue on the one and the end of the
two.
[music] And 2 4 1 2 4 2 4 1 2 4 1 2.
[music]
You can also do crotchets in the right
hand.
maybe nice [music] and choppy
except for the last one where you can do
an accent. So, the last one could be 1 2
3 4 1 2 3 [music] 4 1 2 3 4 1 2 3 A 4 1
2 A 4 1 2 A 3 F 1 2 A 3 A 4 1 2 A
[music]
Okay, the actual goal I thought I'll
have for [music] you in this lesson is
the right hand plays at the two and the
four. So
1 and 2 and 3 and 4 and 1 and 2 [music]
and at this stage you might want to use
a metronome so that you get the exact
hit points or you know whether you're on
time or not. So it'll go 1 2 3 4 1 2 3 4
1 2 3 4 1 2 3 4 Left hand's not doing
[music]
it's doing Charleston. up.
[music]
>> [music]
>> 3 4 1 3 1 3 4 1
[music]
F sharp
B
E
A
D [music]
G
C.
So the left hand was pretty much holding
the Charleston. Now, another nice thing
for those of you arpeggio players out
there is we can develop a nice cascade
around the Charleston. So what I mean by
that is you play the root, then you play
the fifth, then you play the third or
the seventh,
and then you play the seventh [music] or
the third
or the third and the seventh
[music] and swing and play four
consecutive
eighth notes. and two and three and four
[music] and and so you're kind of
playing the Charleston
but in this cascading manner. [music]
4 1 2 3 You can use a [music] sustained
pedal to hold it. 1 2 3 4 1 2 3 [music]
4 1 2 3 4 1 2 4 1 2 3 [music] 4 1 2 3 4
1 2 3 4 1 3 4 1 and 2 and 3 and 4
[music] and 1 can hold that.
[music]
Okay. So you can also do the Charleston
in the right hand.
>> [music]
>> What I like to do to start off is to
snap at the 2 and 4. So 1 3 4 1 2 3 4 1
2 3 4 1 2 3 4 [music] 1 2 3 4 and so on.
Right. So once you've done with the
snapping
with the right hand playing the
Charleston
3 4 1 2 [music] 3 4 A one a two bring in
some left hand and imagine the snapping.
So 2 [music]
3 and 2. Let the left hand do it. One
and the three. That'll be nice. 1 and 2
4 [music] and 1 and 2 3 and 1 and 2 and
3. Of course, the left hand can also
upgrade by just playing slowly or
increment by playing semi briefs.
[music]
4 1 2. Then you can play quarter notes.
>> [music]
>> and then minims.
[music]
[snorts]
With the minimums, you can add the
fifths.
There [music] we go.
You can also add in a hand clap at the
four. Maybe both the hands start off and
then you clap at four.
shift.
So, it also makes it a bit tricky to
shift because you have to take your
hands away from the piano and then bring
them back.
Clap
clap
clap.
You can also kind of snap at the three
and four. A double double finger snap of
both hands. So,
it's tough to do because you have to
recover faster
clap and so on. So, it's a bit tricky
right now because even in this video, my
mic is literally on top of me. So, I
don't want to hit the mic. So I have to
move my hand back and then front. So
it's a good challenge maybe to practice
with a mic. Who knows? Okay. So in a
nutshell, what we've learned is we've
learned basically the dominant seventh
chord as six pairs. We practice them as
shells. So you don't have to learn them
as separate chords. Well, that's another
school of thought, but right now we've
learned it as shells. So you practice
those shells which are 3 seven or 7 flat
3 circle of fifths counterclockwise. and
then start off with the Charleston
rhythm in the regular one and the
displaced manner. And then we work at
hand independence, achieving hand
independence or different things in both
hands which make sense for a piano
player, you know, executing or playing
this genre. to practice this lesson a
