Autumn Leaves – Bass Duet – Double Bass & 6-String Electric Bass – Bass Practice Diary – 11 May 2021
I always thought it would be fun to make a jazz trio with double bass, electric bass and drums. In my head it would be something like this. However, my double bass skills are not the best. So ideally in this trio I would play the electric bass and the double bass would be played by someone who can solo, play with a bow and express themselves musically on the instrument.
I shot this video by recording the double bass part first. It was done in just one continuous take. At the point when I played the upright bass part, I hadn’t worked out any of the electric bass part. Having recorded the upright bass I then had a few goes at playing along with it with my Overwater Hollowbody 6-string bass. Once I was happy with what I was doing, I shot the bass guitar part. If you saw my video from two weeks ago featuring three jazz lines on 4-string bass, you might notice that I used one of the lines at the end of the first solo chorus.
I was basically just practicing improvising on a standard. It’s something I do quite regularly, although I rarely go as far as recording a bass line on the upright. Normally I’ll record the bass line on bass guitar and play over that. However, I feel like the double bass adds an extra layer of jazz authenticity, even with my limited double bass skills.
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.
The Chords
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.
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!
The Altered Scale – Bass Practice Diary – 16th April 2019
Jazz musicians love to play on dominant 7th chords. And the altered scale is a really important scale to practice if you want to create a jazz sound when playing on these 7th chords. I think that using the altered scale is often perceived as “advanced” harmony. But, as with most things, it’s easy when you understand it. So, here’s my very quick guide to using the altered scale on bass.
What is the altered scale?
The altered scale is a mode of the melodic minor scale. Meaning that it contains all of the same intervals as a melodic minor scale. The altered scale is essentially what you get when you play a melodic minor scale starting finishing on the 7th note of the scale.
So, what’s a melodic minor scale? It’s basically only one note different from a major scale. If you take a major scale and change the major 3rd to a minor 3rd, you have a melodic minor scale.
Here’s the notes of an F major scale.
F major scale
And here are the notes of an F melodic minor scale.
F melodic minor scale
Notice that the only difference is the third note. It’s an A natural in the major scale and an Ab in the melodic minor.
If you play the notes of an F melodic minor scale but use E (the 7th note) as the root note. You would be playing an E altered scale.
When you think about the notes of the F melodic minor with an E as the root note, it creates these interval relationships to the root note.
E altered scale
The 3rd of E7 would, of course, be written as G# not Ab. But the altered scale creates some interesting theoretical anomalies like that. Because the major 3rd note (Ab/G#) is actually the 4th note of the scale.
How do you use the altered scale?
As I mentioned at the start, the altered scale works really well on dominant 7th chords. You can think of the altered scale as being a kind of extended dominant 7th arpeggio with lots of chromatic alterations.
The scale includes the root, major 3rd and dominant 7th notes which are the fundamental ingredients of a dominant 7th arpeggio. But the other four notes are all chromatic alterations of some kind. Hence why it’s called the altered scale.
You can alter chord tones and extensions by moving them one semi-tone up or down. The 5th of E7 is B natural, but in the altered scale the 5th has been flattened to Bb. So the altered scale could be used on an E7b5 chord.
The 9th can be altered by sharpening or flattening it. The altered scale uses both alterations. So you could use it on an E7b9 or an E7#9 chord. The final alteration is a b13.
So you can use the altered scale to play on any of these altered dominant chord types. And you will sometimes see the chord symbol E7alt. Which implies a chord that could include any or all of these alterations.
So if you want to start using this altered dominant sound on your dominant 7th chords. Then start to think about using a melodic minor scale that starts one semi-tone above the root of the chord. So, if you’re playing on a D7 chord, think Eb melodic minor. For A7, thing Bb melodic minor, for G7 think Ab melodic minor, for B7 think C melodic minor etc.
Having said that, I don’t think that soloing on Giant Steps needs to be very difficult. As long as you start slowly and focus on internalising the sound of the chords before you increase the tempo.
One of the reasons that John Coltrane’s Giant Steps has it’s fearsome reputation is because of the chord changes in the first two bars. The first bar starts on a Bmaj7 chord for two beats and immediately changes to a D7 chord on beat three. Which is a key change to G major. The second bar starts with a resolution to a Gmaj7 chord. Then it changes key again. This time to Bb7 on beat three which is the fifth of Eb major.
So the tune starts with three different keys in two bars. Needless to say, if you’re not prepared for it, it will catch you out. And many Giant Steps solos have failed before they’ve begun because musicians can’t negotiate these quick key changes quickly enough.
This chord movement in bars 1 and 2 repeats itself in bars 5 and 6 but transposed so that the progression starts on Gmaj7. And it’s this chord progression that defines Giant Steps. So if you want to improvise on Giant Steps you need to spend some time really working on this two bar chord progression.
Use the Chord Tones
My first piece of advice would be to come up with lines over this two bar progression using chord tones. The progression itself is already complex enough on it’s own that you don’t need to add lots of chromaticism or substitutions to make your lines sound interesting. It’s amazing how many interesting sounding jazz lines you can come up with on Giant Steps using nothing but roots, 3rds, 5ths and 7ths.
Here are three different lines that I came up with which use nothing but chord tones.
Giant Steps Licks for Bass Bars 1-3
You can transpose each of these to work over bars 5 and 6. But here’s another one that I wrote specifically to be played over bars 5-7.
Giant Steps Lick for Bass Bars 5-7
I don’t work out these licks so that I can play them in a solo. I do it to help me get the sound of the chord changes into my ears. And the more lines like this that I work out, the more likely I’ll be to be able to improvise something like this in a solo. So feel free to play through my licks and practice them, but also come up with some of your own.
I honestly feel that this two-bar chord progression is the key to unlocking Giant Steps. Once you can improvise over this tricky chord sequence, the rest of the progression is easy, dare I say it. It’s just a sequence of II – V – I’s in three different keys. Eb major, G major and B major.
Playing on II – V – I’s is a jazz musicians bread and butter. There are hundreds of lessons and videos out there about playing on them.
Learn a Jazz Bass Lick by Jeff Andrews – Bass Practice Diary – 19th March 2019
I heard the news a couple of days ago that Jeff Andrews had passed away. He really deserves to be remembered as one of the great jazz electric bass players. I know him best from his work with Mike Stern. He played on albums such as Time in Place and Between the Lines which have been among my favourites for a long time. As well as his work with Mike Stern, he’s also played with jazz and fusion greats like Michael Brecker, Bob Berg, Vital Information and Steps Ahead.
After hearing the news, I immediately started listening to some of those albums again. And I also found a really cool compilation of his solos on Youtube. It really struck me what a great musician and improviser Jeff Andrews is. And predictably I started trying to work out what he was playing. What I found was a goldmine of incredible jazz lines improvised on electric bass.
Using Inside and Outside Lines
What struck me about his style was his brilliant use of inside and outside lines. It’s a commonly used technique of many jazz improvisers. Incorporating lines that are both inside the harmony and outside the harmony as a way of creating tension and resolution. Jeff Andrews is an absolute master of this. He improvises lines at high speed that outline the harmony, but then take you way outside the harmony before bringing you back in for the resolution.
Jazz Blues Bass Lick
The lines he creates are so cool, and I could have picked any one of his lines as a demonstration. But I choose this one which is from a Mike Stern tune called Bait Tone Blues.
Jeff Andrews Jazz Bass Lick
This line takes place over the last four bars of blues in F. And it starts by clearly outlining a ii – v in the key of F. But then follows a sequence which starts on a B natural and ends with a sort of chromatic run featuring the notes A, Bb, Ab, E and G. That’s an uncomfortable sounding sequence of notes when you play it over a standard blues turnaround in the key of F. But then having played that outside sequence, he immediately brings it back inside the harmony by outlining a C major triad at the end. With the C7 functioning as the V chord in the last bar of the blues.
It’s really hard to analyse some of these outside lines other than to say that when you play the lick through, it just sounds really cool. And it shows that Jeff Andrews had incredible musical instincts as an improviser. He had the ability to throw in outside passages and make them sound like they fit with the inside harmony. He will be missed.
Play Bass on Sus Chords (Suspended Chords) – Bass Practice Diary – 12th March 2019
Sus chords or suspended chords create a really cool modern sound. Last week I put out a video of a bassline I’d written on four sus chords. This week I want to explain a little bit of the theory behind my approach to playing on these types of chords.
What is a suspended chord?
I think there is often confusion over what the term suspended actually means when it relates to music. A suspended chord is simply a chord that doesn’t contain a third. A basic musical triad (three note chord) usually contains a root, a third and a fifth. And it’s the third that defines the chord as being either major or minor.
Suspended chords don’t use the third. The third is usually replaced by a fourth (sus4) or a second (sus2). Therefore they’re not major or minor chords. They need a different name, and that name is suspended. The name itself doesn’t really tell you anything important about the nature of the chords or how to play on them, so most musicians usually abbreviate and call them sus chords.
How do you play on sus chords?
Personally, I take a jazz approach to playing on sus chords. A basic sus4 or sus2 chord (like the kind you might find in a pop song) is all very well. But for me these chords get really interesting when you start extending them, creating richer fuller harmonies and chord voicings.
When I’m playing bass on sus chords, I like use the notes of a major 9th chord or arpeggio. But I think of the root note of the sus chord as being the 9th of the major arpeggio.
So, for example, G is the 9th of F major. So I can think of a Gsus chord as being an inverted Fmaj9 chord with the 9th becoming the root.
F major 9th arpeggio on G sus chord
If you think of the notes of an Fmaj9 chord with the root G, then the chord tones are root, 2nd (9th), 4th, 6th (13th) and b7th (dominant 7th). So you can think of my Gsus chord as being a G7sus4 chord with a 9th and a 13th added as chord extensions. However, I would simply think of it as Gsus and the chord extensions are there at the discretion of the musicians voicing the chords.
More sus chord arpeggios
These kind of extended sus chords create a really cool modern jazz sound. I think they’re cool because they aren’t major or minor, so the sound of them is always a bit of a question mark. Almost like you’re not really sure when you hear them, how they’re supposed to make you feel.
In the bassline I played in last week’s video, I used four sus chords Gsus, Bbsus, Dbsus and Esus. In each case I thought of the root note as being the ninth of a major 9th arpeggio.
Ab major 9th arpeggio on a Bbsus chord Cb major 9th arpeggio on a Dbsus chordD major 9th arpeggio on a Esus chord
Quartal Chord Voicings on Bass Guitar – Bass Practice Diary – 26th February 2019
I haven’t done a video about bass chord voicings for a while. So, this week I’ve decided to practice some of my favourite jazz chords, quartal chord voicings. Quartal harmony is a jazz term which means harmonising chords in intervals of a fourth.
4th Intervals
I did a video recently about playing modern jazz lines using 4th intervals. But I thought after making that video that I wasn’t telling the full story about using 4ths in modern jazz. The quartal chord voicings themselves create a very distinctive modern jazz sound. It’s instantly recognisable once you become familiar with the sound.
Chords are traditionally voiced in intervals of a third. Using quartal voicings in jazz became popular in the 1960’s after Miles Davis made quartal chord voicings a feature of his composition So What from the 1959 album Kind of Blue.
Quartal harmony was a sound that then became associated with the great John Coltrane Quartet of the early to mid 1960’s. The chords were supplied by pianist McCoy Tyner, who is synonymous with quartal harmony, and one of my all time favourite jazz pianists.
McCoy Tyner was using these voicings at a time when the Coltrane Quartet was playing a lot of modal jazz. Meaning that there weren’t lots of chord changes. And the emphasis was more on scalic improvisation over static harmony. So What is also a modal jazz piece. So, if you’re looking to apply some of these quartal chord voicings, then modal jazz tunes are a good place to start.
Quartal Harmony on Bass
The bass is setup for playing quartal chord voicings because the strings are tuned in intervals of a fourth. Which is why it amazes me that more bass players don’t use quartal chord voicings. Many of the chord voicings in the video can be played with just one finger. But despite this simplicity, they create a sophisticated jazz harmony sound.
Here is an A major scale harmonised in 4ths.
A major scale – quartal chord voicings
In the video, I’ve used the open A string as a root note underneath all of these voicings.
When you play this, it doesn’t sound like a typical major scale harmonisation. That’s what’s so great about quartal harmony. You can take simple harmony, like a major scale, and completely change it’s character, without needing to change or add any notes.
It works for all of the modes of the major scale. Here is the Dorian mode harmonised in 4ths.
A dorian – quartal chord voicings
Applying Quartal Harmony to Jazz
I’ve already mentioned that quartal chord voicings are extremely well suited to modal jazz. If, for example, you’re playing a modal jazz composition with long periods on a minor seventh chord. Like So What or John Coltrane’s Impressions. Then you’re faced with a challenge of how to make just one chord sound interesting.
One solution would be to apply the dorian chord voicings that I’ve written out in the example above. It gives you seven different options for voicings that you could play over a single minor seventh chord (Am7 in the example above). You could use any or all of these voicings to help create a feeling of movement in the otherwise static harmony.
You can apply quartal harmony to virtually any scale or mode. In this next example I’ve applied it to an A harmonic minor scale.
A harmonic minor – quartal chord voicings
The same chord voicings can also be applied to any of the modes of the harmonic minor scale, which includes the altered scale.
One of the fourth intervals in the harmonic minor scale actually comes out as a major third. So, some of the voicings in the example above are not strictly quartal. Because they mix fourths with a third. But it still creates some interesting sounds and you can do your own experimenting to decide which of the voicings are useful.
Auld Lang Syne on 6 String Bass – New Year Bass Practice Diary – 1st January 2019
Here’s my bass arrangement of Auld Lang Syne. This is my second New Year as a parent. Since becoming a parent my New Year’s celebrations have become much more mellow. I haven’t taken a New Year’s Eve gig these last two years because parental responsibility takes precedent.
It feels strange, because I’ve been playing somewhere on New Year’s Eve for at least 10 straight years prior to this. But these days I can’t think of a better way to ring in the New Year than with a nice mellow arrangement of Auld Lang Syne on my six string bass.
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 as I stated in the video, I hope that the coming year gives you many opportunities to play the bass!
Modal Jazz Improvisation on 3 Basses – Based on Flamenco Sketches – Bass Practice Diary – 20th November 2018
This week I was inspired by the chord changes of Miles Davis’ modal jazz masterpiece Flamenco Sketches. I used the chords as the basis to improvise using three basses, fretless electric, acoustic upright (double bass) and acoustic bass guitar.
This is the second video I’ve made playing jazz with these three basses. If you’d like to find out more about why I’m using them, then check out my previous video called Playing Jazz with Three Different Basses.
Miles Davis and his Compositions
Once again, I’ve featured a composition by the great jazz trumpeter and band leader Miles Davis. My previous video featured a composition called Solar. It wasn’t a conscious decision to feature the same composer twice. However, it does reflect the influence that Miles Davis’ music has had on me and my own jazz education.
The two compositions, Solar and Flamenco Sketches, actually have very little in common. Other than that they’re written by the same composer. Solar is what jazz musicians would refer to as a Bop tune. And Flamenco Sketches is an example of Modal Jazz. They represent very different stages of Miles Davis’ career even though they were only written about five years apart.
Also, in this video, I’m only using the chord progression for Flamenco Sketches as a basis for improvisation. Whereas, I played the melody of Solar as well as an improvised solo, which is more or less consistent with the Bop style.
The album Kind of Blue, is one of the most famous jazz albums of all time. It was released in 1959 and it marked a complete change of direction in modern jazz. It’s debatable whether or not Miles Davis actually came up with the idea of Modal Jazz. Because there are earlier compositions by other composers, that could be described as modal jazz even though the term wasn’t used to describe them at the time. But Kind of Blue undoubtedly established modal jazz as a major movement in modern music, and it marked a sea-change in jazz.
What is Bop?
The concept of modal jazz is actually very simple. In order to understand it, you must first understand Bop, which had been the prevailing style in modern jazz up until the late 1950’s. Modern jazz really started with a style of music called Bebop, and particularly two gentlemen, Charlie Parker and Dizzy Gillespie.
Miles Davis began his career as a teenager, playing with Charlie Parker and Dizzy Gillespie in the late 1940’s and early 1950’s. So his background was in Bebop and he continued playing a style of Bop called Hard Bop throughout the 1950’s when he lead his own band. The composition Solar first featured on a Miles Davis album in 1954, and it is typical of a Bop style jazz melody.
The style of Bebop was all about complex melodies and fast moving chord progressions. In order to play it you needed both technical skill, to keep up with the pace, and also exceptional understanding of harmony and ability to navigate fast moving chord and key changes. The Hard Bop movement was a bit less high paced and a bit more soulful, but it still relied upon the melodic and harmonic style of it’s predecessor Bebop.
What is Modal Jazz?
Modal jazz, by contrast, doesn’t rely on chord progressions. Where Bop compositions tend to change chords in virtually every bar. Modal compositions tend to stay on just one chord for extended periods. The improvisers role in modal jazz is not to navigate continually shifting harmony as in Bebop. It’s to create melody from modes.
Modes are essentially scales. Each chord implies an accompanying scale which the improviser can use to create a tune. Flamenco Sketches is a classic example of a modal jazz composition, it is essentially just five chords, or five modes. Very simple in theory, but it’s also one of my favourite jazz compositions.
Flamenco Sketches Chords
Flamenco Sketches starts in C major, I would use a C lydian mode to improvise on this first section. Find my video about Lydian Sounds here. The second chord is Ab7sus4. The sus4 chord voicing is intentionally ambiguous, because it doesn’t define the chord as being either major or minor. Therefore there are a number of different ways you can approach it. Miles Davis uses a major triad starting on the fourth Db, which I’ve tried to emulate in my improvisation.
The third chord is a Bb major chord, and again you can use a lydian mode here. This precedes one of my favourite moments in any jazz composition. Which is a change from the Bb major to a D phrygian dominant mode. This has to be one of my favourite chord changes. I remember seeing Ron Carter’s band play this piece in London in about 2003. It was such a beautiful concert. One moment from the concert that I can still remember all these years later was when the band changed to the D chord in Flamenco Sketches. Ron Carter had an extended range on his fourth string so he could reach a low D on his bass. I’ve tuned the fourth string on my upright bass down to a D in the video to emulate this.
It’s the phrygian dominant mode that gives the piece it’s Spanish flavour. You can find my video about the phrygian dominant mode here. The Spanish sound is integral to the composition. For this reason, this section of the song lasts twice as long as the other four modes. The final chord is a Gm7 chord, you can play a dorian mode here.
Artificial Harmonics
The original idea for this video came because I was practicing a technique for artificial harmonics which I’ve adapted from the guitar. I’ve never done artificial harmonics like this on bass before. I use a different technique usually. I haven’t done a video about artificial harmonics yet, but I will do one soon. So stay tuned to my Bass Practice Diary if you want to learn this technique.
I was using this technique on a guitar and I started wondering if I could use it to play chords on my acoustic bass guitar. Once I found it worked I immediately had the idea of playing the chord changes for Flamenco Sketches using the technique. I recorded it and added the improvisation on double bass and fretless bass, and that’s the video!
