Timing Exercise #1 – Sixteenth Notes in Groups of Three – Bass Practice Diary 120

Timing Exercise on Bass Guitar – 16th Notes in Groups of 3 – Bass Practice Diary – 11th August 2020

The concept of this timing exercise is very simple. You take any sequence of three notes, and play the sequence as continuous 16th notes in 4/4. So, you subdivide the beats into four, but you play a pattern of three, which creates a simple polyrhythm. Each time you play the sequence, it will start on a different 16th note. After three bars, you will have played all of the different permutations of where that sequence can start in a bar of 4/4. So, if you play the sequence correctly for three bars, the sequence should begin again on beat one of bar 4.

The Exercise and Variations

This would be a simple version of the exercise. It’s a “one finger per fret” exercise, but each note is played three times.

Timing Exercise - 16ths in three note groupings - One finger per fret
Timing Exercise – 16ths in three note groupings – One finger per fret

I would more commonly play the exercise using triads, as I have here.

Timing Exercise - 16ths in three note groupings - Fmaj and Em triads
Timing Exercise – 16ths in three note groupings – Fmaj and Em triads

You could also apply the same idea to practicing scales. Here is a C major scale played in three note groupings. First ascending and then descending.

Timing Exercise - 16ths in three note groupings - C major scale ascending
Timing Exercise – 16ths in three note groupings – C major/A natural minor scale ascending
Timing Exercise - 16ths in three note groupings - C major/A natural minor scale descending
C major/A natural minor scale descending

Naima Chords on 6-String Bass – Bass Practice Diary 117

Naima by John Coltrane: Chords on 6-String Bass – Bass Practice Diary – 21st July 2020

Naima is one of my favourite jazz compositions (I have a lot of favourite jazz compositions). I know that a lot of other musicians feel the same way about Naima, because it has an incredibly beautiful and unusual chord progression. It comes from the John Coltrane’s Giant Steps album, which I’ve featured before in my Bass Practice Diary. It was recorded in 1959, the same year as Kind of Blue, and it stands alongside that album as one of the iconic jazz albums of the 20th century.

However, Naima is not the type of composition that most people would associate with that album. Giant Steps tends to be remembered for it’s burning fast bop tunes with furiously fast key changes like the title track and Countdown. Naima is a slow ballad that Coltrane played many times, and I think many people forget that it originally featured on the Giant Steps album. However, Naima does have something in common with those other tunes I mentioned, it has an incredibly innovative chord progression.

Naima Chords

A long time ago I set myself the challenge of arranging these incredible chords on my 6-string bass. I quickly realised that I needed to change the key to get the chords in the B section to work well. The reason being, that there’s a chord in the B section with the melody note Db. The highest fretted note on a 24 fret 6-string bass is C, one semi-tone too low. So, to voice the chord accurately, you need to play the top note way down on the 13th fret of the 1st string. It isn’t wrong to do that, but it just doesn’t sound very good.

So, to make it sound better, I transposed everything down a semi-tone. I played that top note as a C on the 24th fret of the first string. An extra advantage of transposing was that I could use the open A string as the bass note, instead of the Bb in the original key. When I play Naima I also tune my E-string down to a D. I use the open string to play the peddled bass note in the A section. If you want to transpose my arrangement into the original key, then you could tune your bass up a semi-tone.

When you see Naima written in books, you normally see the chord progression in the A section written something like this.

||: Bm7/Eb | Em7 | Amaj7+5/Eb – Gmaj7+5/Eb | Abmaj7/Eb :||

Then the B section is usually written like this.

Bmaj7/Bb | Bb7b9 | Bmaj7/Bb | Bb7b9 |

Bm maj7/Bb | Bmaj7/Bb | Abmaj7/Bb | Emaj7#11/Bb

Changes similar to these feature in the jazz Real Books and the Coltrane Omnibook. I even found them on Naima’s wikipedia page (which I thought was unusual!)

The Major 7th Chords Trick

I’ve never found these Real Book chords helpful. I worked out by ear that you could create the sound of Naima by moving major 7th chords around over the pedalled bass notes. I do understand that when you change the bass note, you change the chord. So, a lot of these chords don’t function as major 7th chords. I gave the example in the video that when you play an Fmaj7 chord over a D bass note, you get the sound of Dm9.

Recently, I was playing Naima with a Saxophonist, and we were using the Real Book chord changes. I mentioned to him that I’ve always thought of the tune as being entirely made up of major 7th chords over pedalled bass notes. He told me that a scrap of paper had been discovered with John Coltrane’s handwritten chords for Naima. They were written out for Tommy Flanagan, the pianist on the original recording. Coltrane had written every chord as a major seventh chord.

I wasn’t sure I believed that this piece of paper really existed. I wanted to believe it, because it tied my way of thinking about the tune to Coltrane’s way of thinking about the tune. But, if such a piece of paper existed, then why do all the books and publications still stick with this unnecessarily complicated way of writing out the harmony? So, today I did some research to see if there was any legitimacy to the story. This is what I found.

It just goes to show the power that the jazz Real Books have had in defining how we think about jazz standards. Once a tune is written in the Real Book. The Real Book chord changes become the definitive chord changes that everyone uses. But often, the changes in the Real Books are very different to actual chord changes.

How I Play the Chords on 6-String Bass

This is how I’ve arranged the chords on my 6-string bass. I can’t pretend that this is 100% like either the Real Book changes or the Coltrane changes. It’s simply the best way that I’ve found to recreate the sound of Naima on a bass guitar.

Fretless Bass Line with Bass TAB – Bass Practice Diary 114

Fretless Bass Line with Bass TAB – Bass Practice Diary – 30th June 2020

This is a fretless bass line that I wrote recently as part of a piece I’m working on. During the lockdown I’ve been trying to keep my creativity going by writing some music. The drums are provided by my good friend Lewis Davies who has appeared on my channel before.

The Bass Line

Fretless Bass Line
Fretless Bass Line

The bass line has a triplet feel. I’ve written it in 4/4 but I could have written it in 12/8. If you’ve read my book Electric Bass: Improve Your Groove then you’ll know that I like to count triplets with the syllables ta-ki-ta. Using those syllables, the two ta’s become the beat and off beat in a shuffle or swing feel. But I think it’s how and when you use the other syllable, ki, that can make a triplet feel really pop. Notice that I’ve placed a note on this subdivision after the second beat in every bar of this bass line. To my ears, that is what defines the character of this line.

Carol of the Bells – Christmas Bass Practice Diary 88

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 hope you enjoy the video, please check out my previous Christmas bass videos if you haven’t already. This one is from last Christmas and it’s Let it Snow, Let it Snow, Let it Snow. And this on is The Christmas Song aka Chestnuts Roasting on an Open Fire. Stay tuned to Johnny Cox Music in 2020 for loads of new bass videos. I’ve completed 52 brand new and original bass videos in 2019 and I’ve got lots more planned for the future.

Rhythm Changes with Tim Pettingale – Bass Practice Diary 71

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.

Tim Pettingale

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.

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.

Jazz Licks Bass Clef Version – Bass Practice Diary 67

Jazz Licks Bass Clef Version – Bass Practice Diary – 30th July 2019

This week I’m practising jazz licks from a book called Jazz Licks Bass Clef Version. I wanted to feature it this week because it ties in nicely with last week’s Bass Practice Diary Video. Which featured some of my own jazz licks written over the harmony of a short section of Herbie Hancock’s composition Dolphin Dance.

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.

Dolphin Dance on Three Basses – Bass Practice Diary 65

Dolphin Dance on Three Basses – Bass Practice Diary – 16th July 2019

This week I’ve been studying transcriptions of Herbie Hancock’s classic 1965 recording of Dolphin Dance from the Maiden Voyage album. I’ve always loved it as a piece of music and I think it perfectly captures what Herbie Hancock was about at that time and why he’s a genius. I’ve been attempting to transfer what I’ve studied onto three basses. 6 string fretted and fretless electric basses as well as upright bass.

Dolphin Dance

The harmony is highly complex and jazz musicians have argued for decades over what are the correct chords to play. So, my main interest in analysing the transcriptions was to find out how Herbie Hancock himself voiced the chords, not only for the melody but also behind his own solo.

In spite of the complex jazz harmony, Dolphin Dance is first and foremost, a beautiful tune. And therein lies the genius of the composer. I’d compare it to tunes like Monk’s Round Midnight, Mingus’ Goodbye PorkPie Hat and Coltrane’s Naima. All beautiful melodies that are elevated by unusual and challenging harmonic structures.

Bass Solo Transcription

I’ve transcribed one whole chorus of my bass solo. I’ve written the chord symbols in above the stave for reference. But I would advise you not to take them too seriously. I took the chord symbols from a book, but I wasn’t following them when I played my solo or when I recorded the chords. I was trying to follow the notes that Herbie Hancock actually played, and the chord symbols don’t necessarily represent a completely accurate picture of that.

Augmented/Whole Tone Symmetrical Jazz Bass Exercise – Bass Practice Diary 64

Augmented & Whole Tone Symmetrical Jazz Bass Exercises – Bass Practice Diary – 9th July 2019

This week I’ve been practising symmetrical jazz bass exercises. Symmetrical means anything that uses the same repeating intervals over and over. For example diminished chords are symmetrical because they use only intervals of a minor 3rd. And in this video I’m using augmented triads (major 3rds) and the whole tone scale (major 2nds).

Why practice symmetrical exercises?

I was first turned onto the idea of practicing symmetrical exercises years ago when I first ready Ray Brown’s Bass Method. For those of you who don’t know, Ray Brown was a pioneering jazz upright bass player. And he is famed as an innovator of using the upright bass for playing bop style bass solos. So his book gives a great insight into how he thinks.

But he doesn’t use a lot of words, it’s mostly just exercises and there are many of them. There are pages and pages of symmetrical exercises and all he tells us is that we should practice them alongside scales because they’re extremely useful for playing jazz vocabulary. But he doesn’t explain why, and it took me a while to fully appreciate just how useful these exercises are.

First of all, the fact that these exercises are symmetrical means that they work over a number of different chords, not just one. In the video I’m using dominant 7th chords as an example. If you use an exercise to harmonise a dominant 7th chord. And every interval in the exercise is the same. Then logically you can use the same exercise to harmonise different dominant 7th chords starting with a root note on every single note in the exercise.

The augmented/whole tone exercise

The exercise in the video is built around the whole tone scale starting and finishing on C. It has six notes in it, C, D, E, F#, Ab and Bb. And the six notes are harmonised into two augmented triads, C, E & Ab and D, F# & Bb. These notes can be used to harmonise the following dominant 7th chords. C7, D7, E7, F#7/Gb7, G#7/Ab7 and A#7/Bb7. The scale will create the intervals root, 9th, maj 3rd, #11th, b13th and dominant 7th. Three chord tones (R, 3rd, 7th), one unaltered extension (9th) and two altered extensions (#11, b13).

Using Open Strings for Position Shifts – Bass Practice Diary 58

Fretless Jazz Lines – Using Open Strings for Position Shifts – Bass Practice Diary – 28th May 2019

This week I’ve been coming up with jazz lines on my fretless bass. But specifically I’ve been trying to use open strings to help me make fast accurate position shifts in these jazz lines. I’ve been inspired to try this after I transcribed a blues solo played by the phenomenal bassist Tom Kennedy in last week’s practice diary video.

I think that one of the best ways to improve as a musician is to work out passages played by great musicians. I often use transcriptions and books written by other people, which are useful tools to use. But I feel that I learn the most when I work it out for myself.

Use open strings to make position shifts

The next challenge, after you’ve worked out a piece of music, is to see what you can take from it and incorporate into your own playing. And the thing that struck me most about Tom Kennedy’s blues solo was the way he was organising his left hand and his use of the open strings.

Can I take some of that and apply it to my own playing? In order to find out, I started writing out jazz lines for my fretless bass that use open strings and position shifts in the way that I’ve seen Tom Kennedy do it.

The theory behind it, is that if you play an open string before you shift position, then that gives you a little bit of extra time to make the shift. And it also gives you a reference note to help you hear if your position shift is accurately in tune. Which is extremely important on fretless bass. It’s a technique that I believe Tom Kennedy has adapted from playing upright bass. But he applies it onto fretted electric bass and he plays jazz lines at ferocious speed.

The fretless jazz lines

My fretless bass is a 6 string. I don’t have another fretless bass because I sold my four string fretless when I bought my 6 string. However, I usually write my TAB’s out for 4 string so that all bass players can use them. So, these three examples are all written for 4 string bass. Even though they’re played on 6 string in the video.

The first one that I played, at the start of the video, is written on the middle eight section of Rhythm Changes. It’s the second most popular chord progression in jazz after Blues changes.

The next line that I shared in the video is meant to be played over the first four bars of Stella By Starlight.

And the final example is over the changes for the first four bars of John Coltrane’s classic composition Moment’s Notice.
