Inside/Outside Pentatonic Jazz Exercise for Bass Guitar – Bass Practice Diary – 5th May 2020
This week I’m featuring a pentatonic jazz exercise that I came up with. Since I released my pentatonic jazz lick video a few weeks ago, I’ve been coming up with exercises to help me play these inside/outside pentatonic ideas all over my bass and in different keys. I’m featuring the exercise for two reasons. One is because it’s a useful exercise to practice, but the other, more important reason, is to help you come up with exercises of your own by sharing my process with you. This is how I came up with the exercise.
A minor pentatonic exercise
An idea for an exercise usually starts with something very simple, and then I find ways to make it progressively more challenging. In this case, I started with the notes of an A minor triad. Then I took those three notes through the notes of an A minor pentatonic scale by moving each note one scale step downwards on each repetition. Like this.
Then I changed the feel from triplets to 16th notes. That created a three against four polyrhythmic feel. The pattern is three notes but each beat had four subdivisions.
Then I added the II-V-I inside/outside idea from my last pentatonic video. If you think of the Am triad as being chord II in a II-V-I in G major, then you would play two beats on A minor. Then two beats on D7 before resolving onto the one chord, G major, in the second bar.
The three scales used are A minor pentatonic on the A minor chord. The outside scale is Bb minor pentatonic on the D7 chord. And the exercise resolves onto B minor pentatonic on the G major chord. Three pentatonic scales separated by a semi-tone. Two of the scales contain entirely inside notes in the key of G and the other contains entirely outside notes.
6-String Bass Solo & Chords with Bass TAB & Chord Diagrams – Bass Practice Diary – 14th April 2020
This week I’ve transcribed a 6-string bass solo that I played in practice. It follows on from what I was doing last week, finding creative ways to use pentatonic scales in jazz solos. These days I often practice the same ideas on both guitar and bass. In this case I started by playing some pretty chords on the guitar. Then I came up with two pentatonic scales, a tone apart, that worked on each chord. So, each chord had a different pair of scales. I then tried to improvise lines on my 6-string bass using the two pentatonic scales plus a third outside scale that sits exactly between the two scales. Using this idea I was trying to create inside/outside jazz lines in the same way I did for my pentatonic jazz lick last week.
Having done this I then switched it around. So, I worked out how to play the chords on my 6-string bass and I improvised solo lines using the same system on the guitar. Here are the chords and scales that I used in the video.
The first chord is Emaj9, and the two inside scales are C# minor pentatonic and D# minor pentatonic. The reason I chose those two chords is that I was thinking of the Emaj9 chord as lydian, and those two scales spell out the E lydian sound very well. The outside scale would have been D minor pentatonic, but I didn’t use it on the solo I included in the video.
I then played a sequence of major chords over a peddled E bass note. D/E creates an Esus chord and I used the B & C# minor pentatonic scales and C minor pentatonic for the outside notes. Then on C/E I used A & B minor pentatonic and Bb for the outside notes and then A/E I used F# & G# minor pentatonic and G for the outside notes. In each one of these slash chords I was thinking of the major chord as being lydian.
Finally I played an Em9 chord which I treated like a II-V-I in D major, exactly as I did last week. In fact, I tried to used the lick from last weeks video on this chord. I didn’t execute it perfectly but the idea still came across.
These solos are a long way from being perfect, they represent what I’ve been working on this week, which is the point of my bass practice diary. I’m including the transcriptions here to help you see my thought processes as I tried to create these lines. But I’m sure that you can take these ideas and improve on what I’ve done, which is what I’m going to do as well. It’s actually a great exercise to transcribe your own solos, because you can immediately think about how you would do it better next time. Here is the bass solo I played in the video.
Pentatonic Modern Jazz Lick – Bass Practice Diary – 7th April 2020
This week I’ve written a pentatonic jazz lick to try and demonstrate how pentatonic scales can be applied to modern jazz. If you think that pentatonic scales are just easy scales for beginners then you need to read this. I think Google and YouTube probably need to read this as well, because when you search for pentatonic scales, you get a lot of content that is targeted at beginners.
The Pentatonic Scale
Pentatonic means five notes. So, you could technically have any number of different five note scales that could be labeled pentatonic. But there is one pentatonic scale which is “the” pentatonic scale. The same scale can be used for both major and minor and it goes like this.
It’s an incredibly useful scale because pentatonic melodies are universal. I can’t think of many styles of music that don’t use pentatonic melodies. They have a very distinctive character.
Many people associate pentatonic melodies with blues guitar playing. But the applications of pentatonic melodies go way beyond blues licks. Not that there’s anything wrong with playing blues lines. Blues melodies and phrasing are hugely important in jazz, and blues phrases played well can be both beautiful and sophisticated.
However, it’s possible to approach pentatonic melodies in a completely different way. And that’s what I’m looking at this week.
One of the great strengths of the pentatonic scale is it’s versatility. If you’re only using the scale one way, then you’ve missed part of the point of them. If you take any major key, then you always have three different pentatonic scales within that key. Using the key of D major as an example, you have B minor/D major, E minor/G major and F# minor/A major pentatonic scales all within the key. Each creates a different sound played against a D major chord.
Pentatonic Jazz Lick
My pentatonic jazz lick uses three pentatonic scales in the key of D, but none of them are D major pentatonic. I’ve used E minor pentatonic scale on the Em7 chord, which is chord II, and I’ve used the F# minor pentatonic scale on Dmaj7, chord I.
The other scale that I’ve used is F minor pentatonic. This is a scale which gives you all of the notes that are not in the key of D major. I’m using this scale on an A7 chord, chord V. Why play a scale that uses all theoutside notes? To create tension that can be resolved on the one chord (Dmaj7).
Of the five notes in an F minor pentatonic scale, F, Ab, Bb, C & Eb. Four of those notes are altered extensions on an A altered dominant chord, b9, #9, b5 & b13. The other note is Ab. That’s not a note you want to feature too prominently on an A7 chord, because it’s a major 7th on a dominant chord. You can use it, but you have to be careful how you use it. I’ve used the Ab once in my lick and it’s the last note before resolving to chord I. The Ab functions as a chromatic approach note leading to A natural, which is a chord tone in the Dmaj7 chord. Here’s the lick.
Superimposing II V I Licks
I’ve written the line above onto a II V I in D major. But I wouldn’t necessarily choose to play the lick in that context. When I came up with the lick, I was thinking about it more as a straight 1/16th note feel on a funky modal idea.
Jazz musicians love to superimpose II V I lines onto individual chords. You could play that entire lick on a single Em7 chord or Dmaj7 chord or A7 chord.
You could even play it on a G major chord and it would create an inside/outside lick with a lydian sound.
