I VI II V Chord Progressions on 6-String Bass – Bass Practice Diary 84

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.

Chord substitutions

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.

G7 chord on 6-string bass. Root, 3rd and 7th.

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.

Six String Fretless Bass Arrangement – I Know You – Bass Practice Diary 83

Six String Fretless Bass Arrangement – I Know You – Bass Practice Diary – 19th November 2019

Multi-tracking fretless bass is a big challenge. It’s hard enough to get any fretless instrument to sound in tune on even a single bass line. But to try and get multiple tracks of the same instrument to sound in tune with itself is really hard. Because if any one note is slightly out of tune, then the whole thing sounds bad. So, I set myself a challenge this week to see if I could arrange a tune using only my Warwick Thumb SC 6-string fretless bass.

I Know You by Mike Stern

The tune that I chose was I Know You which comes from a collaboration between Richard Bona and Mike Stern on the album These Times. It’s a beautiful tune and I highly recommend checking out the original version. Richard Bona’s vocals and bass playing are just sublime.

My version probably doesn’t do justice to the original, but it kind of works in it’s own way. The intonation certainly isn’t perfect, but I include it in my Bass Practice Diary as a demonstration of the kind of ideas that I like to use to help me improve my intonation on fretless bass. If you have a loop pedal and a fretless bass, try multi-tracking some of your own fretless lines. It’s hard to get it to sound good!

Chord Scales on Six String Bass – Bass Practice Diary 79

Chord Scales on Six String Bass – Bass Practice Diary – 22nd October 2019

I’ve done a few videos recently about chord voicings and progressions for six string bass. So, I felt that I really needed to do a video about chord scales. Because chord scales might be the best way to practice playing chords on bass. If you really want to explore the full potential of every chord voicing that you play. As well as learn how to use them all over the fretboard. Then practising chord scales is the way to achieve that.

What is a chord scale?

You can turn just about any chord voicing into a chord scale. The idea is, that every chord implies a particular scale. There may be more than one scale option for a particular chord. For example, for an E7 chord you could us E mixolydian. But you could also use plenty of other scales, like an E lydian dominant scale. In that case you could come up more than one chord scale.

Once you have a chord voicing and a scale, you simply create a chord scale by moving all of the notes in your chord voicing up one scale step at a time.

So, I’ll use the C major chord scale that I used in the video as an example. The C major scale goes C, D, E, F, G, A, B, C. And the notes of the C major chord are C, E and G. So, to make the second chord in the scale, the C becomes D, E becomes F and G becomes A. D, F and A is D minor. And when you continue moving up the chord scale you get seven different chords. One chord starting on each of the seven notes of the C major scale.

More Chord Scale Examples

Here are some more examples from the video. This first one is in F major and uses a basic triads voicing.

F Major Chord Scale - triads
F Major Chord Scale – triads

Here is the same key using seventh chords.

F Major Chord Scale - 7ths
F Major Chord Scale – 7ths

This next one is in the key of A major, and it uses inverted triads. Meaning that the root note is not the lowest note in the chord voicing.

These are all fairly simple chord scales. If you’d like to find a slightly more advanced application of this idea. Then check out this video. It’s a voicing that I learned from Oteil Burbridge, that I then turned into a chord scale.

Half Rounds on Acoustic Bass Guitar – Bass Practice Diary 78

Half Rounds Bass Strings on 6 String Acoustic Bass Guitar – Bass Practice Diary – 15th October 2019

I get a lot of questions on social media about bass strings. What strings do you use? What do you think of these strings? etc. One question that I’ve never been able to answer is, what do you think of half rounds? Because I’ve never tried them, until now. So, I’ve just put a set of D’addario ENF71 Half Rounds on my Warwick Alien Deluxe 6 string acoustic bass guitar. The string gauges are 30-45-65-80-100-130.

Why Half Rounds?

There was a reason why I wanted to try half rounds on my acoustic bass guitar beyond just curiosity. I normally use bronze round wound strings on my Warwick Alien Deluxe. In fact, I use round wounds on all my basses. The Warwick Red Label Bronze Strings that I normally use sound great. And they are amazing value for money. But there is one issue with using round wound strings on acoustic instruments (it’s the same with steel string acoustic guitars) which is, that the strings can make annoying squeaking noises when you shift position.

An obvious solution to this issue is to use flat wound strings. I’ve tried this, and the problem is, that I don’t like the sound of flats on bass guitar. To me they sound very dull and dead, and I need the brightness of a round wound string to create the sound I’m trying to achieve.

So, the question in my head was, can half rounds provide me some of the brightness of a round wound string but with less friction (squeak), like a flat wound string? And I have to say that my early response is very good. They seem to do exactly that. The next test will be, how long will they stay bright for? That may have to be the subject of a future video.

Jazz Chord Progressions – Part 2 – I III7 IV V – Bass Practice Diary 77

Jazz Chord Progressions on 6 String Bass – Part 2 – Bass Practice Diary – 8th October 2019

Here’s Part 2 of the video I started last week about playing jazz chord progressions on six string bass. Last week I was looking at the chord progression I III IV V. And I came up with some diatonic voicings on my six string bass to take me through that progression in a few different keys. This week I’m including some common and simple chord alterations that you can add, to make that chord progression sound more interesting.

I – III7 – IV – V

I mentioned last week that there are two common ways to play through the I III IV V progression. The first is with a minor 7th chord on chord III. Which is the correct voicing if you harmonise all the chords according to the major scale of the key you’re in (diatonic harmony). But there is a common jazz alteration, which is to play the III chord as a dominant 7th chord. Listen to the opening chords on the melody of the jazz standard Someday My Prince Will Come and you’ll recognise that sound.

Here is how I would play that chord progression in the key of E on a six string bass.

I III7 IV V Chord Progression on Six String Bass
I III7 IV V Chord Progression on Six String Bass

You’ll notice that I’ve included either extensions or alterations on each voicing except the very first one. The first chord is E major 7th, which I’ve voiced like this.

There is one obvious alteration that I could make to this chord, which would be a sharpened 4th (commonly referred to as 11th). That chord alteration would change the sound of Chord I to a Lydian sound. The chord would look like this.

Chord III7 and IV

In the example in the video I’ve played the III chord as G#7b13, like this.

But it’s important to understand that it isn’t the b13 note which is the outside note in this key. The G#7 chord is already a chord substitution because the major 3rd, C (or B#) isn’t in the key of E major. The b13 note is actually the note E, which obviously is in the key of E major.

The IV chord I’ve played like this.

The inclusion of the #11 here is a normal diatonic note to play on a IV chord in a major key. A simple chord substitution here would be to play F# minor 7th instead of A major.

Chords V and I

The V chord is where you can really have some fun with extensions and alterations. In my example I’ve used a B7b13 voicing.

But you can also alter the 9th by sharpening or flattening it.

And you can even alter the 5th by flattening it as well. These kind of altered dominant sounds would often be used as chord V in a minor key. Chord V in a major key would be more conventionally played without alterations, such as B9 or B13.

But I really like the use of the b13 in this case, especially because I’ve voiced the final I chord as E major 9th with the ninth at the top.

So those two chords, B7b13 – Emaj9, create a little chromatic melodic movement. The b13 on the B chord is the note G, which drops onto the F# which is the 9th of the E major chord. It could also go chromatically up onto G# which would be the major 3rd of the E major chord. These are chromatic approach notes which are a common melodic device used in jazz.

Jazz Chord Progressions – Part 1 – I III IV V – Bass Practice Diary 76

Jazz Chord Progressions on Six String Bass – Part 1 – I III IV V – Bass Practice Diary – 1st October 2019

I’ve done a few videos by now about playing jazz chord voicings on the bass. So, this week I wanted to start a series of videos about playing jazz chord progressions. The idea is to take some of the chord voicings that you hopefully already know, and apply them to simple popular chord progressions. It’s the logical next step once you’ve started to incorporate chord voicings into your bass practice regime.

The I-III-IV-V or I-III-IV-V-I Chord Progression

The chord progression I’ve chosen this week is I-III-IV-V. And I’ve resolved all my examples back to the I chord at the end, so it’s actually I-III-IV-V-I. But that often doesn’t happen in real jazz situations. So, in the key of C major, the diatonic chords would be C major, E minor, F major and G dominant. However, in jazz the III chord can also be played as a dominant 7th chord. So, it could be E7 instead of E minor.

Many of these examples were inspired by the jazz guitarist Ted Greene and his book Modern Chord Progressions. The book is obviously written for guitar not bass but I’ve still managed to adapt some of his ideas onto my 6 string bass. I’ve included four examples in the video. Each one is in a different key, and here they are.

Jazz Chord Voicings on Bass Guitar

If you’d like to have a look at some chord voicings before you start trying to play these progressions. Then please check out any of the following videos. This is a video I made about playing jazz chord extensions on bass guitar. And here is a video about playing quartal chord voicings which are great for jazz. This one is a video about adding chord extensions using a right hand tapping technique.

There’s also the Oteil Burbridge video which I referred to in the video. And I’ve also done a four part guide to playing chords on the bass. Which is very old and needs to be updated, but it still contains some useful information.

Applying Jazz Vocabulary to Jazz Standards – Bass Practice Diary 70

Jazz Vocabulary on Jazz Standards with Six String Bass – Bass Practice Diary – 20th August 2019

Last week I was writing out and practicing 16th note jazz lines on II-V-I’s. When you’re practicing jazz vocabulary like that, the next logical step is to try to apply the vocabulary to the chord changes of a tune or jazz standard. And that’s what I’ve been doing this week.

Why do jazz musicians practice playing II-V-I’s?

When I first came across the idea of practicing II-V-I’s, I couldn’t understand why jazz musicians were so obsessed with this one very simple chord progression. But now I get it. Because once you can play lines on II-V-I’s, you can then use those lines in such a huge number of musical situations. Even when there isn’t a II-V-I written in the music, you can superimpose the II-V-I harmony with your lines over it.

Here are just a few examples of what I’m talking about. If you are playing on a minor 7th chord. You can treat that chord as a chord II and play II-V lines over it. Or, if you’re playing on a dominant 7th chord, you can treat it as a V chord and do the same thing. The most obvious place to superimpose a II-V-I is on a major chord or major 7th chord. Using these kind of ideas, jazz musicians have become masters of turning just about any harmonic progression into a sequence of II-V’s or II-V-I’s.

So if you can get good at improvising on II-V-I’s, then you can improvise on so many different chord progressions and harmonies.

Applying jazz vocabulary to standards

Practicing jazz vocabulary in this case just means playing lines that work over common jazz chord changes. Most commonly II-V-I’s. It’s essentially like learning licks. The vocabulary could be lines that you’ve worked out yourself or they could be lines played by someone else. If you’re going to learn to improvise in a jazz style, I think it’s essential to practice some jazz vocabulary. And that’s basically what I was doing last week.

When you practice jazz vocabulary it’s a good idea to transpose it into different keys. It’s an even better idea to apply it to the changes of a real jazz standard. Because then you have to think about how and where you can use the lines. As well as changing the key to follow the harmonic movement of the standard.

I’ve written out two examples. This first one is on the first eight bars of In Your Own Sweet Way.

In Your Own Sweet Way - Jazz Vocabulary Exercise
In Your Own Sweet Way – Jazz Vocabulary Exercise

As you can see, there are lots of II-V’s in this tune. Both major and minor. So, it works really well for applying this kind of jazz vocabulary. My next example was on Miles Davis’ tune Solar.

Solar - Jazz Vocabulary Exercise
Solar – Jazz Vocabulary Exercise

Why practice jazz vocabulary?

Now I should point out, as I did in the video, that this is just an exercise. I wouldn’t choose to improvise like this. Because I don’t use licks or preprepared vocabulary when I improvise. I know that a lot of jazz musicians do use licks in their solos. And there’s nothing wrong with doing that. But it doesn’t work for me. Because I see improvisation as spontaneously creating something in the moment. And that’s what I love about it. If I were to apply a preprepared idea into an improvisation it would feel incongruous to me, and so I don’t do it.

The reason that I practice licks and vocabulary is so that I can hopefully absorb the sounds and melodic ideas. So that hopefully when I want to improvise a jazz solo, I can come up with similar ideas of my own.

16th Note Jazz Lines – Bass Practice Diary 69

16th Note Jazz Lines on 6 String Bass with Bass TAB – Bass Practice Diary – 13th August 2019

This week I’ve written out some 1/16th note jazz lines on a II-V-I chord progression in C major. If you’ve read my book Electric Bass: Improve Your Groove, then you’ll know that I love to practise subdivisions. In fact, I believe it’s probably the most important thing that every bass player should practice. And this week I’ve been working on a tricky little subdivisions exercise. Playing 1/16th notes on a jazz swing feel!

Why is it hard to play 16th notes on a swing feel?

A 1/16th note feel can be described as a straight feel. Straight, in this case means anything with a subdivision that is divisible by two. 1/8th notes, 1/16th notes etc. But a swing feel is a triplet feel. Meaning the subdivision is three not two. So playing 1/16th notes over a triplet (swing) feel requires playing a different subdivision to the rest of the band. And that requires really good time keeping discipline.

You’ll also notice that the 1/16th notes feel fast, even on a quite moderate tempo swing feel. So there are technical challenges in playing these lines accurately. As well as the challenge of getting the timing right. Here are the lines that I wrote out for the video. If you try playing these, I would recommend counting the 1/16th notes using the Konnakol syllables Ta-Ka-Di-Mi as I did in the video.

The Bass Clef Real Book – Bass Practice Diary 62

Using the Bass Clef Real Book – Melody and Bass – Bass Practice Diary – 25th June 2019

Jazz musicians love to practice with Real Books. And most Real Books are now available in bass clef editions. I have several different editions of bass clef Real Books, such as this one. And in this video I’m demonstrating a system of practicing with the Bass Clef Real Book that combines playing melodies with bass notes. I’ve seen guitarists using this system but it’s not often used by bass players.

What are Real Books?

Real Books are big books filled with hundreds of jazz tunes and standards. The arrangements are mostly written very simply as just a single melody line with chord symbols written above. Some of the tunes have little bits of additional arrangement written in, such as a bass line or harmony. But mostly they just distill each tune down to the simplest structure of melody and chords. The concept was created so that jazz musicians could use a standardised melody and chord progression for each tune when playing them at jam sessions.

How can you use Real Books when you practice?

There are a few different ways that you can use Real Books when you practice. The obvious one is for learning the melody and chords of famous jazz tunes. And they’re also good for sight reading practice. There are a wide range of jazz tunes in most Real Books, everything from slow simple ones to fast complicated Bebop lines. So there should be something to practice, no matter what your reading level is. You could also practice improvising on the tunes with the addition of play along backing tracks.

But this week I’ve been trying something different with my Real Books. Instead of just reading the melodies alone, I’ve been trying to include the root notes of the chords, to make a simple solo arrangement of each tune. This is a concept that I’ve heard jazz guitarists like Julian Lage and Martin Taylor talk about.

The idea is that it helps you to learn the tunes by boiling them down to the fundamentals of melody and bass. So rather than thinking about chord changes (which jazz musicians do a lot) you are thinking more about how does the melody interact with the simple bass line root movement.

I’ve only recently started doing this, but here is a transcription of one of my early attempts. The tune is All of You by Cole Porter.

Searching, Finding on fretted and fretless 6 string bass – Bass Practice Diary 61

Practising John Patitucci’s Searching, Finding – Bass Practice Diary – 18th June 2019

Searching, Finding was written by John Patitucci and it featured on his self titled debut album. This week I was reading through a book of John Patitucci transcriptions. It’s an unusual bass book, from the point of view that most of it is written in the treble clef rather than the bass clef. But if you can cope with the treble clef reading, then there are great tunes in it, like this one.

I should point out that the only part of the transcription that I’m playing in the video is the melody. The solos are all improvised by me and I’ve written out one of the choruses of my solo in bass TAB.

How I practice tunes on bass

One of the reasons why I’m posting this video is because it gives an insight into the way that I practice learning tunes. When I say “learning tunes” I don’t just mean learning the melody, I mean melody, bass line, chord progression, structure etc. Everything that’s involved in learning a composition.

The first thing I’ll do is make myself a simple backing track, usually involving drums and chords. I’ll programme the drums in ProTools and add chords on either piano, guitar or six string bass. In this case I played the chords on piano.

When I have my simple backing track I’ll loop it and practice playing the melody, bass line and improvised solos on it. And that’s what you can see me doing in the video. I’m using my fretless six string bass to play a walking bass line and improvise on the modal section. While my fretted six string bass is used to play the bass figure in the modal section and the melody and solos during the choruses.

My solo chorus on Searching, Finding

When I study an artist’s transcription, like John Patitucci’s solo on Searching Finding. I don’t do it so that I can perform his solo or rip off his licks. I do it so that I can study the notes and the phrasing that he uses over the harmony. So that I can then use the information to assist my own improvisation. Before I start improvising I will often write out some lines that fit over some of the trickier harmonic sections. In the first solo chorus in the video, starting at 0:59, you can see me putting some of my ideas into practice. Here is the transcription of that chorus.

Six String Bass Solo on the changes of John Patitucci's Searching, Finding
Six String Bass Solo on the changes of John Patitucci’s Searching, Finding

Once I’ve analysed an artists solo and tried to assimilate what I can into my own ideas. I will then try to improvise in the purest sense of the word. Meaning that I will try not to think about any pre planned ideas and just improvise off the cuff. This is what you can see me doing in the second chorus of solo starting at 2:24 in the video.

Hopefully at this point I’ve started to internalise the melody, harmony and structure of the composition. And this information will come out in my improvisation without me having to consciously work it out in advance. The solo I played in the video partly demonstrates this, although it isn’t perfect yet.
