Introduction to Triad Pairs on Bass Guitar – Bass Practice Diary – 7th January 2020
This week I want to introduce some basic triad pairs exercises. The basic concept of playing triad pairs on bass is that you take two triads (three note chords) that don’t have any notes in common. Meaning that you have six different notes. And then you use those triads to makes lines and exercises.
Why use triad pairs?
Triad pairs are now a really common concept in jazz improvisation. But it’s not only jazz musicians that use them. You can apply triad pairs to almost any genre of music. They work particularly well for improvisation, but you can also use them to write bass lines.
This week, I’m only going to introduce the most basic form of triad pairs. Which is when you take two major triads that are spaced a tone apart. The reason for spacing them a tone apart, is because the triads function like chords IV and V in a major key. So you can use these kind of lines in any major key by transposing the two triads to the notes of chords IV and V in the key.
All of these exercises are played using the triads C major and D major. Which are chords IV and V in the key of G major. But that doesn’t mean that you can only use these in the key of G major. There are all kinds of interesting and creative applications of triad pairs which I’ll try and cover in my future videos.
There are three obvious ways to voice a triad (inversions). You can put the root at the bottom, the 3rd at the bottom or the 5th at the bottom. This first exercise demonstrates those three different inversions, which you need to learn really well if you’re going to get good at playing these exercises. Bar 1 uses the root position triads for both C and D and then bar 2 uses the 1st inversion and bar 3 uses the second inversion.
This next exercise uses a similar idea, but with triplets. So, you play three notes on each triad rather than four.
Finally, here is a pattern that plays four notes on C and then three on D.
The purpose of playing patterns like this one in exercise 3, is that it helps to make the exercise sound less like a pattern. If you’re playing triad pairs in an improvised solo, and you play three notes up and three notes down, like exercise 2. It will very quickly sound like you’re playing a repeating pattern. That’s ok if it’s the sound you want. But, if you want to make it sound less like a pattern, then a pattern with an odd number sequence (three then four) will create a less predictable feel when played as part of a solo.
Happy New Year – New Year’s Eve Bass Practice Diary – 31st December 2019
Happy New Year! It’s New Year’s Eve and I want to thank everyone who has followed Johnny Cox Music in 2019. I have big plans moving forward into 2020, including a lot more free original bass content, so stay tuned! My second book is almost ready for publication and I’m planning to launch a dedicated teaching website for bass players in 2020.
Here’s a video that I shot last year to help you usher in the new year with a bit of solo 6-string bass. I would have shot a new video this year, but unfortunately I don’t know any other New Year’s Eve song apart from Auld Lang Syne. So this is one of the very rare occasions where I’m recycling an old video. I hope you enjoy it!
Auld Lang Syne
There are a number of ways you can approach harmonising this tune, and I didn’t spend very long coming up with this arrangement. I didn’t write the arrangement down, I just worked out a few things by ear before I hit record.
The loose structure of the arrangement is as follows. I played the first half of the song solo, using simple I, IV, V harmony. I intentionally set it in a key where I could utilise the open strings as bass notes. Then I added some jazz chords and alterations in the second half and immediately overdubbed the melody for the second half of the tune.
This was actually one of the quickest videos I’ve done. The shooting of it didn’t take more than five minutes. But I’m happy with the results. Sometimes playing something “off the cuff” is the best way rather than overthinking it.
I hope you enjoy this bit of bassy mellowness, whether your New Year’s Eve is mellow like mine or a bit more exciting. And I hope that the coming year gives you many opportunities to play the bass!
Carol of the Bells – Christmas Bass Practice Diary – 24th December 2019
Happy Christmas and thanks to everyone that’s been following my Bass Practice Diary videos this year. Here is my new Christmas bass video for 2019. I wanted to find something that I could arrange with a loop pedal and my 6-string bass. I immediately thought of Carol of the Bells. The arrangement of the song immediately lends itself to looping.
The way that I’ve arranged it makes it possible to perform live with two loop pedals, one going into the other. However, I shot this video in two parts with one loop pedal. It’s much easier doing it that way rather than as one continuous take.
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!
TC Electronic Vibraclone Rotary with 6-String Bass Guitar – Bass Practice Diary – 10th December 2019
This week I discovered the Vibraclone Rotary pedal from TC Electronic. They call it a Rotary Speaker Emulator, which to me means it sounds like playing through a Leslie speaker. I’ve never been particularly interested in effects pedals. I very rarely take any with me on gigs. But I do use them occasionally. And if I come across a pedal that sounds good for an affordable price, then I’ll definitely snap it up. The Vibraclone ticks all the boxes of being cheap, interesting and sounding good.
How I use the Vibraclone
The Vibraclone definitely has a retro sound. The Leslie speaker was invented in the 1940’s as an addition to the hammond organ. But it was used as an effect by guitarists such as Jimi Hendrix in the 1960s. The terms Chorale and Tremolo are used on a switch on the Vibraclone to differentiate the slow and fast speed settings. These terms came from the Leslie speaker, which used the same terms for it’s slow and fast settings.
I prefer playing with the slower mode for most situations. I find it a bit more subtle. Although I feel like maybe the faster setting sounds more authentically like a Leslie.
Using effects pedals with bass
Generally I don’t use effects when I’m playing the bass and I’m certainly not an expert on pedals. But the times when I find them useful are when I’m playing a lot of solos. If I’m doing a duo gig for example, I know I’ll be called on to play lots of solos. Having something that can change and add variety to my tonal palette can really add something. If you’re playing your third or fourth solo of the night then you usually need something to help you change it a bit.
When I’m using effects pedals, I prefer to put them through an effects loop rather than directly into the front of an amplifier. I want my pure bass tone to be as undiluted as possible, so I don’t want anything in my signal chain between my bass and the amp.
How the effects loop works does depend on the individual amplifier. On my Ampeg GVT guitar amp I can activate and deactivate the effects loop with a foot switch. That is by far my favourite method of using an effects loop, because it means that when the effects loop is disabled I’m getting no potential discolouring of my sound from playing through a long chain of inactive pedals and patch cables. It’s a great system and I wish that I had a bass amp that worked like that.
The effects loop on the back of the Markbass Little Mark III works slightly differently. It mixes the sound of the effects loop with the clean sound of your bass going into the front of the amp. So the impact of the effects is slightly more subtle as it isn’t impacting on all of the sound coming out the amp. I used a volume pedal on the effects loop to gradually bring in and fade out the effect.
You could use the foot switch on the pedal to turn the effect on and off, but that would still leave the sound of your bass going through the pedal chain in the mix. Anything in your chain will colour your bass tone. Even a true bypass pedal must have some effect on your tone and all the extra cables will as well. Which is why I think it’s very important to use an effects loop, so you can only play through the pedals when you want to. One other major advantage of using the volume pedal is if you’re using multiple pedals that you want to turn on simultaneously.
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.
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!
Truss Rod Adjustment & Setup on fretless Sire Marcus Miller M7 – Bass Practice Diary – 12th November 2019
One of the most useful skills that you can learn as a bass player is to set up your own bass. It’s easy. Two weeks ago I released my review of the Sire Marcus Miller M7 fretless 5-string bass. It’s a good bass, but the setup was a mess when it arrived. So, on the same day that I shot the review, I also made a video about how I set the bass up, and here it is.
Why you should set up your own bass
When I was younger, I always paid a professional luthier to set my instruments up. I thought that a really good instrument needs a professional set up, and if I tried to do it myself I might ruin it. But there was one incident that completely changed my perspective, and I’m very glad that it did.
I was in my mid twenties and I’d been playing professional gigs for a few years. And I always took my basses to the same bass shop to have them set up. A very good shop where they make their own high end custom basses. So they know what they’re doing. I had just spent a lot of money on buying what was, at that time, the most expensive bass I’d ever owned.
The setup was almost perfect on my new bass, but there was a small issue on the first string, with the action being a bit too low. And so, on a few frets, the first string wasn’t ringing clearly. Naturally I took it straight to my usual bass shop where I knew and trusted them. And I paid them to give it a full setup. I didn’t mention the issue on the first string, I thought I didn’t need to. I assumed that as professional luthiers, they would make the setup perfect.
You’ve probably guessed by now, that when I came to pick up the bass two or three days later. The bass was in exactly the same condition that I had left it. Same issue on the first string. And while I was trying the bass out, I over heard the luthier say to his colleague in another room, that he hadn’t known what to do with my bass because the setup had been perfect from the start.
Only you know how you want your bass to be set up
Naturally I was dismayed to have wasted my time and money on a setup that had made no difference to my bass. I asked the luthier to make some extra adjustments, which he did, and they also made no difference. Then I left with my bass, not knowing what I should do. I didn’t complain, because I didn’t want to humiliate the guy, he had done his best.
When I got home, all I could do was try and sort out the issue myself, which I did in less than 10 minutes and I got the bass playing perfectly. And this was a revelation to me. I had always assumed that I couldn’t possibly set an instrument up as well as a professional. But I had fixed a problem in a few minutes that a professional had failed to even identify in three days.
Now, I assure you that I’m not trying to say that luthiers are incompetent or a sham. There is a reason why the luthier couldn’t get my bass setup right and I could. And that reason is because I’m a musician and he isn’t. I’ve heard all of the luthiers in that shop playing basses before, and their bass playing is very rudimentary and basic. Their skills are in making instruments, not playing them. So, when they set up an instrument, their approach is to make very detailed accurate measurements.
The problem with that approach is that it doesn’t take in to account the idiosyncrasies of each individual instrument. The luthier had performed all of the measurements on my bass, and found that everything was as it should be. That’s not really surprising, because it was an expensive bass, and I’m sure that the manufacturer had also made all the same measurements when it left the factory and decided it was perfect.
However, neither the factory nor the luthier in the shop had picked up on the issue that I was having, because they don’t play the bass like I do. And that is the key point. Only I know how I want my bass to be set up. Paying somebody else to do it doesn’t make any sense at all. They can only give me a generic set up based on what they think I want. But if I do it myself, I can make the bass play exactly how I want it to play.
How to set up a bass
There are only really five things that you need to learn how to do. And most of them are extremely easy. The most important, and possibly most difficult, is to set the relief in the neck by adjusting the truss rod. I’ve demonstrated in the video how a luthier adjusts the relief in the neck. But I tend to do everything by feel. I make small adjustments and then I try it out to see how it feels.
I think that is another really key point. Everything you do, just make tiny adjustments and keep trying it out. It might take ages to get it right, the first time that you do it. But it’s the best way, and it minimises the chances of you doing any damage to your bass.
Apart from the truss rod, the other four things that you can adjust are the saddles on the bridge for string height, the intonation on each string, the pickup height and the nut height.
As I mentioned in the video, most basses don’t come with adjustable nuts. I wish they did, check out Warwick’s Just-a-Nut III here. I don’t know why other companies can’t come up with a similar idea. If you don’t have an adjustable nut, you can lower a nut by filing it down. If you want to raise it, you need to replace it with a new nut. This is something that you probably should get a luthier to do, but most bass setup’s can be done without needing a new nut. I’ve only ever had to have a nut replaced twice in over 25 years of playing bass.
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.
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.
Keep following my weekly practice diary on Johnny Cox Music for many more videos about jazz chord progressions coming up soon.
Blues in A with a 10/8 Time Signature – Bass Practice Diary – 24th September 2019
Blues is at the root of so much of what I play. I started out by playing blues as a child. And the blues is also at the root of so much modern music, including jazz, rock, funk, soul… the list goes on. It’s actually incredible when you think about it, how the musical vocabulary of the blues has permeated so much music in the last 100 years or more. But, can you play a blues in an odd meter? That’s what I found myself wondering this week.
Where does blues end and modern jazz start?
Blues has its own rhythmic feels and distinctive harmony. Which have proved very adaptable to other genres of music. And it could be argued that once you break out of these structures, you’re no longer playing the blues. My own musical journey through my teen years took me from blues to modern jazz, simply by a process of trying to expand my harmonic language. It wasn’t a conscious decision on my part to leave the blues behind. I simply started to become interested in upper chord structures and alterations, and expanding my role as a bass player, and modern jazz is where I found myself.
So I’ve no doubt that some people could argue that an odd meter blues isn’t blues, it’s (blues influenced) modern jazz. But I would argue that if you can stay true to the rhythmic feeling, structure and harmony of the blues, while playing an odd meter. Then you can play an odd meter blues. And that’s what I’ve tried to do in this video.
The influence of John McLaughlin
It’s not a completely original idea, although I’ve never heard anyone try to do exactly what I’ve done here. However, I was partly inspired by the jazz guitarist John McLaughlin. There’s a tune called New Blues, Old Bruise on his album Industrial Zen. It’s in 15/8 and I think it’s a brilliantly original approach to playing blues harmonic language. That tune would undoubtedly be classed by most people as jazz fusion, but nevertheless, the blues influence is undoubtedly present.
The other influence of John McLaughlin came from his brilliant DVD called Gateway to Rhythm. In which, he briefly demonstrates a kind of subverted blues shuffle feel in 10/8. The rhythmic phrase he uses is Ta-Ki-Ta Ta-Ki-Ta Ta-Ka Ta-Ka, which is 3+3+2+2. When I heard it I thought it was genius. Because it seemed to capture the feel of a blues shuffle, but it wasn’t a shuffle. I think the phrase originally came from one of his old Mahavishnu Orchestra albums.
Hearing that made me think, if you can capture the feeling of a shuffle in 10/8 then maybe you can play an entire 12 bar blues in 10/8. I haven’t used that particular rhythmic phrase in my blues, because I didn’t want to copy John McLaughlin’s rhythmic phrase. But it did inspire me to come up with the blues in 10/8.
The bass line
The bass line was partly improvised and partly worked out in advance. It turns out that you have to concentrate really hard when you’re playing a 12 bar blues in 10/8. Especially when you don’t just stick to one rhythmic phrase. As I haven’t here, I’ve tried to mix up the rhythms as much as I could. But here is one chorus of transcribed blues bass line in 10/8.
The fretless bass solo
The fretless solo on top was just a bit of messing around. I added it to add some context to the bass line. I found while I was doing it that I had to concentrated really hard on where to start my lines. To make sure they came out in the right place harmonically. I’ve transcribed the solo too and here it is.
