Jazz Guitar – Bebop Scales

jazz guitar scales

Bebop scales are certainly very valuable scales to add to your repertoire, especially if jazz is your bag. If you already know how to play the major scale and all of it’s modes, then you will find playing bebop scales a breeze. The reason being, these scales are essentially the same as the major scale’s modes, with the addition of an extra passing note in each of them. There are also bebop scales derived from the modes of the melodic minor, and the modes of the harmonic minor scale (guide on those coming soon!), but for the purpose of this guide I will only be dealing with the three most used bebop scales, and all three originate from the major scale.

Above is a terrific example of the dominant bebop scale (key of Bb) being played. Wes Montgomery is on fire as always, listen and take note! The bebop scales are frequently used in jazz, and deservedly got their name from their extensive use in the Bebop era (1940s-60s) by such jazz musicians as Charlie Christian, Wes Montgomery, Charlie Parker and Dizzie Gillespie, to name a few. Each scale presented is based on a mode of the major scale, with the addition of an extra passing note which gives it it’s characteristic chromatic run – you always hear the jazz giants flowing through their scales like this.

The bebop scale’s intention was to open up the major scale and give it more of a jazz flavour, and also to introduce a new ‘technique’ for playing over chord changes. Thanks to the added passing tone, if you begin the scale on the root chord tone (1) of the chord playing, and on the downbeat, all other chord tones (3, 5, 7) will also fall on downbeats, while the remaining tones in the scale will occur on the upbeat. This, of course, is assuming the scale is played either ascending or descending, without skipping an interval. These sort of scale runs, peppered occasionally with sequencing, are very common techniques in the world of jazz, as they colour the chords which are being played. Another advantage of the bebop scales is the additional note allows more soloing opportunities, which make it playable over more chords, thus eliminating the need to change scales as frequently as you would with the original major scale modes.

Mother of All Music Theory – The Major Scale

john scofieldI’m not sure why I took so long to write a guide on the major scale, considering it’s easily the most important bit of music theory that you can learn, and knowing it is essential in order to learn other scales and chord theory. I even wrote my guide on modes of the major scale first! But don’t fret, it’s finally here – a guide to the major scale, the mother of all scales. It’s the scale which all other scales are compared to, and from where chords and their progressions derive from; it literally gives birth to music theory. The major scale is the first of the diatonic scales, which is just a fancy word for a seven-note octave repeating scale, which consists of five whole steps and two half steps between each octave. Don’t understand any of that? Don’t worry, you will very soon.

Natural, Harmonic and Melodic Minor Scales

wes montgomeryThis post we’re going to be discussing three minor scales: the Natural Minor scale (Aeolian mode), the Harmonic Minor Scale, and the Melodic Minor Scale.

As you probably know already from my guide on the Modes of the Major Scale, the 6th mode of the major scale is always the natural minor scale, or the Aeolian mode. In the Key of C major, the Aeolian mode is A minor; therefore A minor is the relative minor of C major: every major chord has a relative minor. When you play an A Aeolian as part of the C major scale then they both share the same notes; for example, the pattern for the major scale is: (W = whole step – 2 frets), H = half step – 1 fret)

W – W – H – W – W – W – H
1    2    3    4     5    6    7

Which in C would = C D E F G A B (then back to C again, but at a higher octave.)

Frank Gambale: Modes No More Mystery

The above clip is taken from Frank Gambale’s excellent instructional DVD on guitar modes. You can download it here. The download includes all the booklets and mode diagrams. The video taught me pretty much everything I know about modes and it is absolute essential viewing for any guitarist aspriring to further their knowledge of music theory. Frank Gambale is an Australian Jazz Fusion guitarist and the inventor of the ‘sweep picking’ technique. His understanding of the entire fretboard is second to none and he is undoubtedly one of the most talented guitarists on the map. The video covers modal chord progressions, what they are and how to construct them, and also of course the guitar modes them self. Frank Gambale also gives great examples of how each of the modes sound in the key of C so you can hear the differences between them all.

Guitar Modes: Melodic Minor Scale

Music Theory

This is a continuation from my previous guide: Modes of the Major Scale Explained!

The main difference between the major scale and the melodic minor is its flat 3rd as opposed to the major scales regular third. Therefore the seven modes of the melodic minor scale share only one note difference to the modes of the major scale. This scale is used extensively in jazz!

The seven modes of the melodic minor scale are as follows:

  1. The Melodic Minor (similar to ionian mode, but with a flattened 3rd)
    1 2 b3 4 5 6 7
  2. Dorian b2 (similar to dorian mode, but with a flattened 2nd)
    1 b2 b3 4 5 6 b7
  3. Lydian Augmented (similar to lydian mode, but with a raised 5th)
    1 2 3 #4 #5 6 7
  4. Lydian Dominant: (Lydian b7) (similar to lydian mode, but with a flattened 7th)
    1 2 3 #4 5 6 b7
  5. Mixolydian b6 (similar to mixolydian mode, but with a flattened 6th)
    1 2 3 4 5 b6 b7
  6. Locrian #2 (Aeolian b5) (similar to the locrian mode, but with a raised 2nd)
    1 2 b3 4 b5 b6 b7
  7. Altered (Super Locrian) (similar to the locrian mode, but with a flattened 4th)
    1 b2 b3 b4 b5 b6 b7

You construct these modes in the exact same way as you construct the modes of the major scale, you simply change the root note and you have different sounding mode. i made a diagram to illustrate this (again, in C – click image to make it bigger!):

Modes of the Major Scale Explained!

Music Theory

A lot of guitarists have trouble coming to understand the modes of the major scale, I know it took me many moons to come to grips with it, but once I finally unravelled its mysteries, I realised how simple it really is. The word mode sounds so ambiguous and lame, I prefer to use the word mood, as this word accurately describes what modes really are. Now, describing modes is easy, but using them musically is a bit trickier, however, knowing what they are is the first step. First of all, before you even read this, make sure you know how to play the major scale. It isn’t called the mother of all music theory for nothing. At the very end of this article is a quick little primer on the major scale that might be of some help. Also, for convenience sake, I will be referring to the C major scale, as it is the only major scale that contains no sharps or flats. Also, remember that the chromatic scale is the scale which contains every single note, the word chromatic coming from the word chroma (meaning colour), so the chromatic scale contains every single colour. Scales are simply notes, or colours taken from the chromatic scale, and added to a musical palette. There are literally hundreds of scales, and musicians like Allan Holdsworth have even made up their own. But I am getting off track here. Now before you begin, make sure you know the major scale! I have written a guide on the major scale which you can use as a resource.

This guide is in no way trying to be thorough or extensive, instead I am explaining the concept of modes in its simplest and rawest form. Because, after all, it is very simple, and the last thing I want to do is scare you off with encyclopedic jargon and walls of text. Alright, here we go..!

There are 7 modes (moods) to the major scale, in order they are:

  1. Ionian (the major scale)
  2. Dorian (minor bluesy sounding mode, characteristic note is the maj 6th)
  3. Phrygian (minor spanish sounding mode, characteristic note is the flat 2nd)
  4. Lydian (major sounding mode, characteristic note is the augmented 4th)
  5. Mixylodian (major bluesy sounding mode, characteristic note is the flat 7th)
  6. Aeolian (the (natural) minor scale – flat 3rd, flat 6th, flat 7th)
  7. Locrian (very unstable sounding mode, it’s characteristic notes are the flat 2nd and flat 5th)

A cheesy mnemonic to help you remember the order is:

I Don’t Particularly Like Modes A Lot

Let’s take a look at the C major scale (Ionian), the notes in this scale are CDEFGABC, if we play the C major scale and instead of focusing the tonality on C (the root note) we focus on the second note of the scale (D) then we have a completely different sounding scale – the D Dorian scale – which looks like this: DEFGABCD, we are still playing the same notes of the C major scale but we are getting a completely different sound by concentrating on the D as the root note instead of the C. This is how modes are constructed; if we concentrate on the 3rd note of the C major scale (E) then we have an E Phrygian scale – EFGABCDE – and so on… in this sense it’s best to think of the modes as an anagram of the major scale (change the letters around and the word has a completely different meaning, in this case, change the root note around and the sound/mood changes radically) A good analogy to describe how modes work can be found in conversation, by emphasizing certain words in a sentence the meaning behind the sentence is changed. The best example of this i can think of is found in an episode of Seinfeld ‘The Mom And Pop Store’:

  • ELAINE: Well, I talked to Tim Whatley…
  • JERRY: Yeah…
  • ELAINE: And I asked him, “Should Jerry bring anything?”
  • JERRY: So…?
  • ELAINE: Mmmm…and he said, “Why would Jerry bring anything?”
  • JERRY: Alright, but let me ask you this question.
  • ELAINE: What?
  • JERRY: Which word did he emphasize? Did he say, “Why would Jerry bring anything?” or, “Why would Jerry bring anything?” Did he emphasize “Jerry” or “bring?”
  • ELAINE: I think he emphasized “would.”

I know this sounds confusing, so i made some diagrams to make the learning process a whole lot easier (VISUALISATION IS KEY!)

Modes of the C Major Scale

‘Colours’ of the C Major ‘Palette’

cmajorscaleallmodes

Now putting modes into practice is a different beast altogether, it is a tool used by jazz guitarists mainly to colour their solos based on the chord progression. For example, in a typical jazz chord progression of II V I in the key of C major the chord progression would be Dm7 G7 Cmaj7.

Seeing as how the key of the progression is C major a guitarist could choose to simply play the C major scale (C Ionian Mode) over the entire progression, but if you decide to emphasis the D note instead of the C note whilst the Dm7 chord is playing and the G note while the G7 chord is playing and finally the C note while the Cmaj7 chord is playing, you would be playing the exact same C major scale throughout but you will be using three different modes of the same scale (D Dorian, G Mixolydian and C Ionian) over their respective chords in the progression.

This would mean that you have endless soloing moods to tap into, both major and minor by using the same scale. Here’s a good video to showcase an excellent (Australian!) guitarist using modes of the C major scale to create different moods.

Notice how Frank Gambale is playing the C major throughout the song, but by emphasizing different notes of the scale he creates different moods? The intro sounds triumphant (Lydian), the chorus is very major sounding (Ionian), and the solo is very minor and bluesy (Dorian)!
