How do you get those hip-sounding “outside” tones that make jazz sound like jazz? If you’ll allow me to be egregiously reductive for a moment, modern jazz has educated us in a vocabulary of improvised melodies that begin diatonically, move briefly away from the key, and then resolve back in, producing a very familiar “in-in-in-in / out-out-out-out / in-in-in-in” sort of sound.
This is true for a standard ii-V-I progression at least, and the first place beginners should start searching out those hip, “outside”, or “colour” tones is the V chord. He's the chap who’ll tolerate the most alterations and outside notes being played on top of him.
An “alteration” is a note that’s been changed in the original chord which, when superimposed back onto the original chord, sounds outside. There are only four altered notes – a flat 9, a sharp 9, a flat 5, and a sharp 5 – and what we need to do is find interesting ways to generate some or all of them over a V chord.
Here’s a list of ten possible approaches to playing over a V, starting with the most “inside” sounds, and moving gradually out. All these examples are in the key of F. In a ii-V-I progression in F, the V chord is a C7. The top line shows the notes you play, the bottom shows how those notes relate to the unaltered notes of a C7 chord.
1. V7 Arpeggio. Plays the unaltered notes of the V chord.
C E G Bb
1st 3rd 5 b7
This is basically an arpeggio of notes diatonic to the key of F. Therefore no outside tones here. It’s still perfectly respectable, though, and should not be thought of as uncool.
2. Mixolydian Scale. Plays the unaltered notes of the V chord, plus extensions.
C D E F G A Bb
1st 2 3rd 4 5 6 b7
In essence, C Mixolydian is F Major played from C to C rather than F to F. In other words, it’s another way of arranging the notes of F Major, and therefore contains no outside notes. Sounds good, though.
3. Bebop scale, descending.
C B Bb A G F E D
1 2 b7 6 5 4 3 2
For beginners, the Bebop scale is best thought of as a descending scale, played high to low. It’s basically a Mixolydian scale with an added major (or natural 7th), or you could also think of it as C Major with an added flat 7th. Although it contains no altered tones, the addition of an extra note gives a fluid chromaticism that is a familiar part of the jazz vocabulary. Always start the Bebop scale on a downbeat (the 1 or 2, etc., as opposed to the “and”), as that way the strong chord tones will always fall on strong beats. Try this little experiment: starting on any chord tone C7 (C-E-G-F), play the Bebop scale in eighth notes while counting “1 & 2 & 3 & 4 &.” Notice how the chord tones always fall on the numbers? Cool, eh?
4. Diminished Arpeggio starting a step up from the root of the V chord.
C# E G Bb
b9 3 5 b7
By playing a diminished arpeggio whose root is a step up from the root of the V chord, you’re basically playing a C7b9 arpeggio with no root. As the flat 9 is one of the most obvious and familiar outside notes in jazz, try and find them all over the neck in all 12 keys. A well-timed and tasteful flat nine is well-hip, man, and easy to add without having to get strung out learning tons of new scales. Very Django-ey too. Sweet.
5. Playing a Major 7th arpeggio beginning a whole step down from the V chord.
Bb D F A
b7 9 11 13
This idea is nicked from Robert Conti’s "Source Code" book, The Jazz Lines. By playing a Major 7th arpeggio whose root is a whole step down from the root of the V chord, you hit all the unaltered extensions of the original chord. Over C7 play Bbmaj7, and while you won’t get any outside tones, you will get some interesting ones.
6. A Major 7th arpeggio starting a half-step up from the root of the V chord. Over C7 play, C#maj7.
C# F Ab C
b9 11 #5 1
Another idea pinched from Robert Conti (cheers Bob! Buy Bob’s books!) Play a Major 7th arpeggio whose root is a half-step up from the root of the V chord. This generates two altered tones – that sweet b9 and a cheeky #5 - as well as an 11th and the root note of V.
7. More Robert Conti: play the tritone substitution arpeggio of the Major 7th arpeggio.
Your starting note lies a flat five up from the root of the V chord, and you it doesn't matter whether you play either a Dominant or a Major arpeggio. Over C7, then, play either an Ab7 arpeggio (first example) or Abmaj7 arpeggio (second example).
Ab C Eb G
#5 1 #9 5
Ab C Eb Gb
#5 1 #9 b5
No flat nines here, but what do you want? The moon on a stick?
8. A Melodic Minor scale starting a whole step below the root of the V chord.
Bb C Db Eb F G A
7 1 b9 #9 11 5 13
The Melodic Minor is basically a major scale with a flat 3rd, providing a nicely ambiguous major/minor that reminds me of Boulez. Playing it a whole step lower than the root of the V chord generates b9/#9 alterations.
9. Melodic Minor starting a half step up from the root of the V chord.
C# D# E F# G# A# C
b9 9 #9 b5 #5 b7 1
Same as above, but a bit more dramatic. Twice as dramatic in fact, as over a V chords this will generate all four alterations: b9-#9-b5-#5. Tres hip, mon dudes, which is why playing the Meldoic Minor a half step up from the root of V is one of the most popular and oft-used V chord sounds. For a fantastically enlightening lesson on this topic, check out the John Stowell podcast provided by those community-minded citizens of the Pacific Northwest, Portland Jazz Jams. I just wish I didn't find Melodic Minor so darn hard to remember.
10. The Altered Scale.
C Db Eb E Gb Ab Bb B
1 b9 #9 3rd b5 #5 b7 7
Finally – the motherlode. The Altered scale, as you can see, contains all the possible alterations as well as the natural 7 passing tone and a natural third. Here’s a neat trick to finding the fingering for the Altered scale: play a Dorian pattern beginning on the second note – C# Dorian = Altered scale minus the initial C natural. As C# Dorian is the second mode of B Major, that means you're actually playing in the key of B Major. So, by playing a B Major scale over C7, you are in effect playing the Altered scale.
***This Just In -- New Item*** The Harmonic Minor Scale from the root of the Parent Key's Relative Minor.
Walter just showed me this one, his favourite. Play the Harmonic Minor scale (1,2,b3,4,5,b6,7) starting from the root of the relative minor for the key you're in. In other words, in the key of G, play E Harmonic Minor over D7; in F play D Harmonic Minor over C7; in C play A Harmonic Minor over G7 -- another way to think about it is to start the Harmonic Minor a whole step up from the root of the V chord. But wait, there's more: make sure you play both the natural seven and the flat seven passing tone (I don't know whether this approach is well-known, or whether it's just one of Walt's idiosyncracies). Voila, in the key of F:
D E F G A Bb C (b7 passing tone) Db
2 3 11 5 13 7 1 b9
Lots of extensions, and a flat nine.
To conclude: there are tons of options for playing over the V chord, and all you have to do is decide what sounds you like and how “in” or “out” you want to be. For beginners, it’s not really practical to try and play an entire scale over a V. For a start, even at a moderate tempo of 120 bpm, four beats goes by too quickly to play an entire scale. Second, if you play a scale, that’s exactly what it sounds like – a scale. Try arpeggios instead, or just locating a couple of your favourite colour tones within a scale position that you’re already comfortable with. Also, play a combination of inside and outside sounds, as too much of anything sounds drab and predicable after a while (as in Le Massif’s version of “Autumn Leaves,” where I religiously play Eb every time D7 comes around [Eb = b9 of D7]). Finally, have a look at this free lesson from Jimmy Bruno that explains it all much better than I’ll ever be able to. He suggests simplifying your thinking by concentrating on playing in the Major scale and just adding choice colour tones at appropriate moments. Remember, there are many, many ways to skin this particular cat. Drop me a line if you notice any mistakes.
