“Sir Duke” is one of Stevie Wonder’s
most iconic songs. It’s an ode to the jazz great, Duke Ellington
and in 1977 it was a number one hit. Sir Duke is an R&B song through and through,
but if you dig into the music theory that defines it you’ll hear just how much jazz
actually inspired it. To understand the inner workings of this song,
I had to find someone who can break it down piece by piece.
Hi. My name is Job Collier. I'm Stevie Wonder's greatest fan and I’m here to explain the
magic of Stevie Wonder’s iconic tune, “Sir Duke." So let’s take a look at the song’s structure. There’s a verse, pre-chorus or bridge, chorus,
and a special instrumental section after the chorus which I’m very excited to get into. Before we do all that, let’s talk about
the drums in the intro. One of the intriguing things about this particular
song is Stevie's use of jazz inspired language and his melding of that with pop inspired
language The intro for example is based on this swing
feel and the drums go… Listen to Duke Ellington’s “Take the A
Train” and you’ll hear that same swung hi-hat pattern - a staple of big band jazz. The verse however is a more familiar back beat. This backbeat, with the snare on the 2 and
4 was a Motown staple, the record label that Stevie Wonder was signed to at just 11 years
old. And it’s this backbeat that leads us right into the first verse. Music is a world within itself.
With a language we all understand. Sir Duke, I suppose, is an extrapolation of
a very simple pop structure. So for example these might be four chords that
a pop song might be based around. Chord one, B major in this case. Chord six, A flat minor. Chord four, E major and chord five
F#Major. This specific progression is known as the
doo-wop chord progression because it was so ubiquitous in pop music during 1950s and early
1960s. In the movie Grease there’s actually a song
dedicated to it. What’s that playing on the radio? Why do I start swaying to and fro? Stevie Wonder, he's seeking to experiment
with jazz techniques and jazz harmonic movements within this structure and so what’s he’s
interested in primarily is this idea of chromaticism. Chromaticism, in simple terms, is when you
play notes that are right next to each other in a row. That's the chromatic scale rather than the major scale which sounds like
this. So what Stevie does in this song, which
is really cool, super interesting, and at the time quite unique, was, you've got chord one. You’ve got chord six - so far so good
sounds like a familiar pop song. And then you’ve got the surprising twist
a G7 chord. Which is sort of like a flat six dominant chord. And that's what leads you to chord five. And so he's replaced this chord four with this strange flat six dominant chord. And if you look at the bass movement - A flat,
G, F sharp - that is chromatic and that's what interested Stevie and that's what inspires
me and has inspired many other people about this particular song. Though it's traditional in structure, there are these weird moments when things feel jazzy. There’s just one little instance of chromaticism
in the verse, but in the bridge - where Stevie sings off a list of his Jazz heroes — including
Duke Ellington — his experiments with chromaticism really shine through. There's really only one chord in
this entire section. Now this chord just hops down 3 and hops up
3. This is a crystalline example of chromatic
movement, a chord moves up and down in half steps or semitones. If I were to play the same section diatonically,
which means that all the notes are taken from the major scale, it would sound a bit like
this. Now that is not quite as spicy, and certainly
not as chromatic as this version. This chromatic bridge leads us right into
the chorus of the song, and it’s here that we should probably talk about harmony. Something that has always thrilled me as a
lover of harmony is this idea that you can take a note that feels familiar in one key
or under one chord and that note can stay the same. But underneath it, the chord can change into
something quite bizarre and unfamiliar but it can feel coherent. For example, here’s the melody of the chorus
sung by Stevie Wonder. So all of those notes belong to B major and
Stevie could very easily just have B major under the whole chorus. Now that is very good but it's not quite Sir
Duke. Stevie made the harmony more interesting by calling
out two specific notes from the melody: A sharp and G sharp. Stevie does this very clever thing where
he takes these two notes, A sharp and G sharp. Now, these two notes do belong to B major. They also belong to F minor. And that's such a warm, surprising sound. Here's the melody of the chorus with that F minor added in. What he's done is take this very basic melody, and contextualize it harmonically in a way that keeps us interested, yet feels familiar to us. Wedged right between the chorus and verse
is Sir Duke’s most overt ode to jazz, the “shout chorus.” This is usually the moment towards the end
of a song where the horn section plays joyfully in unison. Now, to understand what that sounds like, here’s
the shout chorus in Duke Ellington’s “Cotton Tail." The cool thing about Sir Duke’s Shout Chorus
is that it’s not just an ode to jazz, it’s an ode to how universal music can be. Cultures around the world have developed their
own unique musical scales that all sound vastly different from each other. But there’s one scale that is found in nearly
every musical tradition across the globe - the Pentatonic scale. It’s just five notes, and it’s what “Sir
Duke” is built upon. So if we begin to make melodies using the
pentatonic scale, it’s extremely difficult to go wrong. Because any note in the scale sounds great. It's kind of like a miracle scale. Now Stevie Wonder approaches the pentatonic
scale in what has become one of the most iconic uses of the scale of all time in this beautiful
shout chorus to “Sir Duke” which goes something like this. So every note from that melody comes from
the B pentatonic scale. This is the B pentatonic scale. B. C sharp. D sharp. F sharp. And G sharp. Of course Stevie Wonder had to adjust it just
a little bit. There is one interesting juicy note that is
added to achieve a sense of jazzines, a sense of blues, and a sense of chromaticism, and
that is the very sneaky D natural here. So the D kind of bridges the gap between the D sharp and the C sharp. Now, those jazzers amongst you may recognize this scale as what's known as the Blues scale. And the blues scale occurs when you add this
kind of spicy note into a pentatonic scale. And what you end up with is something that
feels very reassuring in its simplicity and yet has the element of spice that introduces
the sort of chromaticism that makes jazz, jazz. Without it it would sound rather anodyne. But when we add this in, it's that jazziness has entered
the fray and that's what makes it very memorable to me and also very harmonically interesting. Sir Duke might be Stevie Wonder’s most overt
ode to jazz and the musicians that shaped his musical education, but listen closely
and you’ll hear those influences across his entire discography. Stevie Wonder is one of the greatest musicians
walking the face of the earth, nobody could possibly argue with that sentiment. I think the reason why is that he's capable
of disguising some extremely complex music information within structures that feel familiar
that feel likable, that feel danceable, and singable. But if you if you zoom into what's going on
harmonically, melodically, and rhythmically there's some pretty heavy stuff going on and
that is something that thrills me to no end.
As a musician, I appreciate how good Jacob is at explaining things like this. He actually even taught me something in this video I never even considered before. My revelation: The B pentatonic scale he mentions with the D added is the same scale as the G# Blues Scale. That relationship makes so much sense, but it had never even crossed my mind. I can't count the number of times I've used those two particular scales in my own improvisation without realizing until now how closely related they are. Fascinating.
I love these Earworm breakdowns. They can get me invested in songs or artists that I don't normally care about.
Ive been a fan of this guy ever since i saw his tiny desk performance..the dude is beyond talented
I'm not gonna pretend that I understood any of it, but I enjoyed it nonetheless.
This video made me go down the rabbit hole of Vox Earworm
Also just like stream any of Jacob's music. He's a complete genius
Crap
I forgot how much I loved listening to Jazz back in high school, guess its Rabbit hole time
