Chord Progression on 6-String Bass with Chord Diagrams – Bass Practice Diary – 2nd February 2021
This week I’ve been coming up with chord progressions on my new Sandberg Superlight 6-string bass. I thought this chord progression was quite nice, so I made a video of it. It uses mostly simple chord voicings, triads and the occasional 7th chord. Simple chord voicings tend to work well on bass. Too many notes in the lower register can sound like a mess.
I started out trying to play something in C major, and as you can hear, I ended up in Bb major. I wasn’t necessarily planning that when I came up with this. But that was where my instinct took me, and when I listened back, I liked it. I did think about including bass tablature in the video. But in the end I decided that chord diagrams worked better.
However, if you’re looking for a note for note transcription, here it is with tablature for 6-string bass.

6-String Fretless Bass Modal Improvisation – Bass Practice Diary – 29th December 2020
This is a modal improvisation on my Warwick Thumb SC 6-string fretless bass. What do I practice in the week between Christmas and New Year? Inevitably I’ve practiced less at Christmas than I usually would. Normally I would have been visiting various family members. But all my plans were cancelled at the last minute due to a COVID lockdown announced by the UK government on December 19th. However, despite that, I still have a wife and son at home, so my usual practice time got devoted to trying to make Christmas special for them despite the restrictions.
So, what should you practice at a time when you haven’t done much practice? For me, the answer is, just play! Play for fun, improvise, play for the love of playing music. Don’t worry about whether it’s good or not. Just get the feeling of the strings back under your fingers. So, with that in mind, here’s a video of me improvising on a short modal chord sequence that I’ve been playing around with this week.
I’ve called this a modal improvisation. But how can it be called modal if I’m improvising over a chord sequence? The reason I’m calling it modal is because the chords are not connected by diatonic harmony. So I’m thinking of each chord as being a different scale or mode to improvise on. There is no key that connects the chords. They are simply connected by a bass note, each chord is played over an E bass note.
The chord progression in the video is very simple. It starts on an Eb major chord over an E natural bass note. That chord resolves upwards onto an Emaj7 chord. Then I raise the 5th and make that chord an Emaj7#5 before dropping back onto the Emaj7. These might sound like really small changes, and they are. But each chord change creates the sound of a new mode.
I think it’s an interesting way to think about chord progressions. Rather than thinking about chord changes. Think about changing just one note in a chord and see how that one note changes the overall sound.
Improvisation Strategies on 6-String Bass – Part 2: Naima on Fretless Bass- Bass Practice Diary – 14th July 2020
Naima by John Coltrane has a beautiful but challenging chord progression. Last week, I featured a video demonstrating how I play the chords. But the story isn’t complete without looking at how to improvise over those chords. So, this week I’m demonstrating an improvisation strategy for playing over the part that I find hardest to improvise on.
Modal Chord Progression
Most improvisers think of Naima as being a modal composition. Meaning that they think of each chord as representing the sound of a scale or mode. This is different to the diatonic approach that I looked at in my Improvisation Strategies: Part 1 video. In that video I looked at a I-VI-II-V sequence of chords where each chord represented a different degree in the key of Bb major.
When you hear improvisers analysing how to play Naima, usually you’ll hear them say something like, ” play this scale or mode on that chord, and this scale or mode on that chord etc”. And it’s not wrong to think about the progression as a sequence of modes. If you listen to Coltane playing Naima, you can definitely hear that he is playing complete modes quite often.
However, when I’m coming up with an improvisation strategy, I prefer to think in a more economical way. I want to start with something small that I can expand upon. I want to zero in on the notes that I feel best spell out the sound of the harmony. Remember that you can come up with multiple strategies for playing on the same progression. So when you zero in on just a few notes, you’re not limiting yourself, you’re actually creating the potential for much more variation. Because if you start by using all of the notes from the implied scale or mode, then it doesn’t leave as much scope for expanding and using different harmonic ideas.
Naima Improvisation Strategy
Last week I wrote about how I think of all of the chords as being major 7th chord voicings over a pedalled bass note. I won’t repeat myself, so if you’re interested in the chords check out last week’s post.
This four bar section of the harmony comes from the second half of the B section. The chord symbols that I’ve written are different from the Real Book changes, (even when you allow for the change of key). But I think that my changes reflect the harmony that Coltrane was using fairly closely. I wouldn’t recommend getting bogged down in what the chord symbols are. When I was working out how to play this piece, I wasn’t thinking about chord symbols, I was just trying to recreate the sounds that I was hearing and I put the chord symbols on afterwards. So, here is my improvisation strategy for this short four-bar sequence, I’ve picked out five notes to use on each chord.
Improvisation Strategies on 6-String Bass – Part 1: I VI II V – Bass Practice Diary – 14th July 2020
I often get asked questions about how to improvise. I’ve noticed that people are usually looking for a simple answer, like “you just need to know the right scale.” However, if you’re reading this, you probably already know that it isn’t that simple. To become a fluent improviser, you should work on lots of different improvisation strategies. As part of my own practice, I regularly try to find new and different ways to play through chord progressions that I’ve played on many times. To help demonstrate what I do, I’m presenting one improvisation strategy that I’ve come up with on a I-VI-II-V chord progression.
Before we get into the specifics of this particular strategy, I should say that my end goal is the same for any improvisation strategy. That goal is to be able to improvise all over the fretboard. So, when I practice a strategy, I’ll practice it in multiple positions until I can connect up the notes all over the entire fretboard.
In this particular strategy, I’m looking at jazz improvisation on a I VI II V progression in Bb major. Although I would recommend practicing any strategy in multiple keys. The chords in the key of Bb major are Bb – G7 – Cm7 – F7. Notice that Chord VI is played as a dominant chord rather than a minor 7th chord. This is so that it leads nicely to the II chord. It is a very common chord substitution in jazz (and other styles).
A very simple approach to improvising on a I VI II V progression would be to just play a Bb major or major pentatonic scale. The problem with that as a strategy, is that it ignores the B natural in the G7 chord. So most jazz musicians will prefer to play something different for every chord. This is often referred to as “spelling out the harmony”. So what I’ve done is chosen four different notes for each chord. Each set of four notes is specific and unique to each chord.
Why Play Four Notes for Each Chord?
Normally when a I VI II V is played in the context of a jazz standard, the entire progression is played over two bars. Meaning that each chord lasts for just two beats. With just two beats on each chord, four notes provide more than enough options to fill up the space. If you’re strategy was to use an entire scale, even a pentatonic scale, it would be more notes than you need. It would make improvising on the progression harder than it needs to be.
In choosing the four notes for this strategy, I used arpeggios. You don’t have to use arpeggios, you can use any four notes that you like the sound of. But I think that arpeggios are fundamental to the sound to jazz improvisation, so that’s why I’m using them. I could have simply used a Bb major arpeggio for the Bb major chord and a G7 arpeggio for the G7 chord etc. That would certainly have spelled out the harmony, but it would also probably have sounded a bit predictable. Instead, I opted to play a Dm7 arpeggio on the Bb major chord. The notes of the Dm7 arpeggio played over a Bb major chord create the sound of a Bb major 9 arpeggio without the root note.
By making this substitution, I was thinking of the progression as III-VI-II-V, Dm7 – G7 – Cm7 – F7. This actually simplifies things a lot because it leaves me with two minor 7 chords and two dominant 7 chords. I can use the same strategy for both minor 7 chords and the same strategy for both dominant 7 chords. So I used minor 7 arpeggios on chords III and II and on chords VI and V, I used diminished 7 arpeggios starting on the third of each chord. Bo7 on the G7 chord and Ao7 on the F7 chord. (o in this case means diminished).
Putting the Strategy Into Practice
The best way to put any improvisation strategy into practice is with a backing track. You can find free I VI II V backing tracks on the internet. It’s always a good idea to start slowly, and you can start by just playing the notes you’ve prepared over the chords as an exercise. As you get comfortable doing that you can start to improvise lines that connect up the chords by adding passing notes. Here are three examples that I’ve written out to demonstrate.
The passing notes could be chromatic notes or scale tones. Or to put it another way, they could be literally any note that helps to connect the lines. If you use the four note patterns that you’ve prepared as the structure for your lines, then adding passing notes here and there, won’t interfere with the musical sense of the lines.
There are so many ways that you can vary this one simple idea. You can (and should) practice it in multiple positions on the neck. Here is another position to get you started.
Then try to improvise by connecting up the different positions that you’ve practiced.
Then you could try practicing the same ideas in different keys. You could then try using the same chords, but changing the four note patterns. And finally you could try playing similar patterns on different chord progressions. When you get into practicing these kind of ideas, there really is a lot of different ways you could be doing it. And the more different strategies that you practice, the more fluent your improvising will become.
I VI II V Chord Progressions on 6-string Bass – Part 2 – Bass Practice Diary – 17th December 2019
This week I’m revisiting my introduction to I VI II V chord progressions on 6-string bass video. There are so many ways that you can alter and substitute chords in a I VI II V sequence. Jazz musicians will often alter and add to the progression so much, that it’s almost impossible to tell that it was ever a I-VI-II V progression in the first place.
There really aren’t any rules when it comes to substituting chords. There are certain standard substitutions that are very common, such as the tritone substitution, which I looked at in my last video. But, honestly, you can substitute any chord for any other one that you like the sound of. A lot of it depends on the musical context that you’re playing the substitution in, but also it comes down to opinion. What sounds interesting to some people, will sound odd to others.
This week I’m just going to take you through some familiar chord substitutions and additions to I VI II V’s. These examples go quite a bit further than the examples in my previous video. But, believe me, you can take these ideas much further out than this.
The I VI II V examples
I created this first example by taking the III-VI-II-V example from my previous video and turning all the chords into dominant 7th chords. I then applied tritone substitutions to the VI and II chords. Then I added whatever extensions and alterations that I liked the sound of.
Once you have four dominant 7th chords like this, you can come up with so many variations just by applying tritone substitutions.
My next example derives from the first example. I’ve simply turned the E7, Eb7 and G7 chords into II-V’s. Meaning that I’ve added minor 7th chords before each dominant 7th chord. Each minor 7th has a root note that is a 4th below (or a fifth above) the root note of the dominant 7th chord. I’ve altered the VI chord to make it a major 7th instead of a dominant 7th chord. This completes a II-V-I in the key of Ab major, which is a strange thing to find in a chord progression in C major, but it works!
An Introduction to I VI II V – Chords on 6-String Bass – Bass Practice Diary – 26th November 2019
I VI II V is possibly the most commonly used chord sequence in jazz. So, I think it’s time I started to look at how you can approach playing this simple but versatile chord progression on a 6-string bass. It’s been a few weeks since my last video about playing chords on 6-string bass. So, I’m bringing the series back this week with an important one.
Why is I VI II V so common in jazz?
That’s a question I used to ask myself a lot when I was younger. When you listen to the progression played in it’s simplest form, it’s not particularly interesting. It’s quite practical, because it has a nice cycle of fifths movement, with the VI leading to the II to the V and back to the one. So it can just go around and around, with the V always leading back to the I. It’s a nice cyclical chord movement that takes you back to chord I. And as such it’s very often played on the turnaround of a jazz progression.
In the standard chord progression, chord I is a major 7th chord, chord VI is usually played as a dominant 7th chord. Although if you harmonise the chords using the diatonic major scale it would be a minor 7th chord. The reason it’s usually played as a dominant 7th chord is because it acts as a chord V leading to the minor 7th chord II. And the real chord V is also a dominant 7th chord.
Here is my version of a standard I VI II V chord progression in the key of E.
But to really understand why I VI II V is so popular, I think you need to understand a bit about how and when jazz musicians like to use it.
The first thing that you need to know about how most jazz musicians will use the I VI II V progression, is that they will try to find as many ways as they can to avoid playing the obvious chord progression. They do this by finding chord substitutions and adding extensions and alterations to the standard chords.
I often get people asking me to explain the concept of chord substitutions. But it’s a very difficult thing to do. Because the truth is, that you can substitute any chord with any other chord. The only restriction is what your ear will accept is a valid substitution. And that is a matter of taste and opinion. How much dissonance are you willing to accept?
However, if I was going to sum up the concept of chord substitutions in one short paragraph. I would say that you are looking for chords that have important notes in common with each other. Which brings me neatly on to the most common chord substitution in jazz, the tritone substitution.
Substituting dominant chords
Tritone substitutions can be performed on any dominant 7th chord. The principle is, that any dominant 7th chord shares two notes in common with another dominant 7th chord. Those notes are the 3rd and the 7th. In order to find the substitute dominant chord you need to find a root note that is an interval of three tones away from the root note of the original chord. If you’re not sure what I mean, check out my guide to playing intervals on the bass.
Take the example of the G7 chord. The root is G, there 3rd is B and the 7th is F. You can play it like this.
The tritone substitution would be Db7. The root is Db, the 7th is B (Cb) and the 3rd is F.
Here is the I VI II V chord progression played in C major using tritone substitutions on the two dominant 7th chords. I’ve also substituted chord III for chord one in the first bar.
Michael Brecker Jazz Lick on Bass Guitar – Bass Practice Diary – 3rd September 2019
This week I’ve been working out some jazz lines that Michael Brecker played on Charlie Parker’s tune Confirmation. And this week I’m featuring one particular lick that comes from that tune.
The recording that I was working from comes from a Chick Corea album called Three Quartets. And it features Michael Brecker performing a duet with Chick Corea who is playing the drums rather than his more familiar role as a pianist. The performance is notable for Michael Brecker’s brilliant solo. Which features a number of brilliant jazz lines. And I’ve picked out this particular lick, because I think it fit’s nicely onto a four string bass guitar. Although I should point out that I’m playing the lick one octave below where Michael Brecker plays it. Here’s the lick.
The lick happens in the middle 8, and it’s played on a II-V-I in Db major. I recently wrote about the importance of practicing II-V-I’s in my post about applying jazz vocabulary to jazz standards. This lick is a really useful piece of jazz vocabulary. And when you practice these kind of lines, I would strongly recommend practising transposing them into different keys. Here’s the same lick played in Ab major to get you started.
Rhythm Changes (Oleo) with Tim Pettingale – Bass Practice Diary – 27th August 2019
I’ve written before about the importance of practicing with other musicians. And it was an absolute pleasure this week to welcome jazz guitarist Tim Pettingale to my studio in East London. Tim’s latest book, which I’ve been reading recently, is called Rhythm Changes for Jazz Guitar. So it seemed like a great opportunity to ask Tim to put me through my paces on a Rhythm Changes tune. We choose Sonny Rollins’ tune Oleo, because Tim refers to it in his book.
What is Rhythm Changes?
Rhythm Changes is a 32 bar chord progression which is loosely based on Gershwin’s tune I’ve Got Rhythm. Many famous jazz tunes have been written on the Rhythm Changes. And it’s the second most commonly used progression in jazz after the 12 bar blues. However, just like the blues progression, there are hundreds of variations that you can play for Rhythm Changes. And you rarely hear it played exactly the same way twice. Tim’s book features explanation and solo examples for many of these variations.
In the video, we’ve tried to feature a few cool variations and chord substitutions from the book in our very short rendition of Oleo. I’ll try and explain them very briefly here.
Rhythm Changes chord theory
Rhythm Changes has an AABA structure. Each A and B section is eight bars long. For the first two A sections we played Sonny Rollins’ melody. Then Tim’s solo started on the middle 8, which is the B section. We used the standard Rhythm Changes middle 8, which is four dominant 7th chords each played for two bars, D7 – G7 – C7 – F7.
The A section usually starts with a I-VI-II-V chord progression in Bb major. The VI chord is often played as G7 rather than Gm7. Having played the I-VI-II-V twice, we then played a cycle of II-V’s starting in Eb major. And then going through the keys Db major and C major before resolving back into Bb major. So bars 5-8 of the A section, as we played it, went like this, Fm7 – Bb7 – Ebm7 – Ab7 – Dm7 – G7 – Cm7 – F7 with two beats on each chord.
The next A section took us back to the start of the AABA form. And we started to introduce some chord substitutions. Instead of the usual I-VI-II-V’s, we played Dm7 – Db7b5 – Cm7 – B7b5. It’s a clever substitution for a I-VI-II-V because it creates a root movement descending in semi-tones. The Dm7 is chord III in Bb major. Chord III is a common substitution for Chord I because the notes in a Dm7 chord are the same as the 3rd, 5th, 7th and 9th of a Bbmaj9 chord. The Db7b5 is a tritone substitution for the G7 (chord VI) and the B7b5 is a tritone substitution for the F7 (chord V). The Cm7 is chord II and it’s the only one of the four chords that isn’t substituted.
We played one more A section, during which we played more or less the standard changes. And then we went into another B section. This time we played tritone substitutions on the D7 and C7 chords. So the progression as we played it was Ab7 – G7 – Gb7 – F7.
All of these substitutions and many others are featured in Tim’s book. I would highly recommend it for anyone who plays guitar and wants to learn about jazz. Tim is the author of Jazz Bebop Blues Guitar as well as the Rhythm Changes book. His books are great, because they don’t assume any prior knowledge of jazz. So they very clearly explain the fundamental principles before going on to deliver simple guides to playing and improvising. All his books have an informal and easy to read style. And they contain multiple short examples written in standard notation and guitar TAB, all with accompanying audio Mp3’s.
During Tim’s visit we also shot another video of one of Tim’s original compositions, which was a jazz waltz. Keep checking both mine and Tim’s social media because we’ll be posting that video in the next few weeks.
The book features thousands of licks mostly about 4 bars long. And most of the licks are written over the opening bars of jazz standards. There are 16 standards featured in the book including Invitation, All the Things You Are, Autumn Leaves and the standard I featured in the video The Days of Wine and Roses.
What makes the book so good is that it takes a very comprehensive approach to learning these short sections of harmony. Each standard has 91 different licks in 13 different key signatures. 7 licks are written for each key, from one flat to six flats and six sharps to one sharp, as well as C major/A minor which has no sharps or flats.
The book also features licks written over II-V-I’s and jazz turnarounds. So, there are a lot of licks. All written in bass clef without any bass TAB. So, it’s good for learning the language of jazz improvisation, and it’s also really useful sight reading practice.
Last week I described how I practice playing on jazz standards by breaking the harmony down into sections. And writing out and improvising lines that work over the short sections. That’s the same concept that this book works on. My advice for using this book would be to play the licks in the book and then write out some of your own lines on the same standards. And try to come up with lines that go over all parts of the chord progressions, not just the beginnings.
