Bass Practice Diary is One Year Old – 23rd April 2019

A year ago I decided to start documenting my bass practice by picking one thing that I was working each week and making a short video about it.

As a music teacher, I believe that if you want to keep improving your musicianship, then it’s essential that you keep finding new things to practice. It seems to me that a lot of people get stuck in the same practice routines, practicing the same things. And then they wonder why their playing isn’t progressing in the way that they want it to.

What I’m trying to show, is that there is an almost unlimited number of different things to practice. And many different ways that you can practice them.

I release the videos every Tuesday. And I haven’t missed a week in the whole year. So there are currently over 50 videos. All available for free without subscription.

If you would like to follow my free videos each week then you can always find them here on JohnnyCoxMusic.com. And if you subscribe to my Youtube channel and click on the bell icon, then you should be alerted each week when my videos are uploaded. You can also follow me on my Facebook page Johnny Cox Music. And you can find me on Instagram @johnny.cox.music

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.

How to Improvise on Giant Steps – Bass Practice Diary – 9th April 2019

Last week I posted a video of me practicing improvising on Giant Steps chord changes on fretless and fretted bass. So this week I want to talk a bit about my approach to playing on what are some of the most notoriously difficult chords changes in jazz.

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.

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.

Giant Steps Improvisation on Fretless & Fretted 6 String Bass – Bass Practice Diary – 2nd April 2019

Some jazz tunes are so iconic that every jazz musician and enthusiast should know them. John Coltrane’s Giant Steps definitely falls into that category. The chord changes have made it iconic, because they’re notoriously difficult to improvise on. Over the years it’s become a kind of rite of passage for aspiring jazz musicians to learn to play on those changes.

I’ll do a more complete analysis of how I approach playing on Giant Steps next week. But the purpose of this video is to show how I approach practising any tricky piece like this. The first and most important thing when approaching any difficult repertoire is to start slow. If you want to be able to play fast, then practice slow.

Start Slow and Vary the Feel

When I’m approaching any chord progression, I’m trying to internalise the sound of the changes. It’s much harder to do this if the changes are flying past at 300bpm. Coltrane may have played Giant Steps blisteringly fast, but I’d be willing to bet that he practiced it slowly first.

I love practicing playing over slow changes. You can really enjoy playing over each chord and having loads of time to hear the changes go past. And this will really help you to get the sound of the changes into your ears.

Another piece of advice I would offer, is to practice playing the changes over as many different feels as you can. As you can hear in my video I start by using a slow straight 1/16th note feel, and then move on to a faster swing feel. But that only scratches the surface, there are so many different tempos and feels that you can use.

It always amazes me that some jazz musicians seem to only practice improvising in a swing feel. You can always tell who these people are because they instantly sound very uncomfortable playing in anything that doesn’t have a swing feel.

John Coltrane and Giant Steps

Giant Steps was recorded and released in 1959, which was a watershed year in jazz for many reasons. It came from the album which was also called Giant Steps, and that album is seen by many as a masterpiece of jazz Bop style improvisation and composition. In fact it’s seen by many as the ultimate recording in that style of jazz.

You can find my bass TAB and analysis of a John Coltrane lick from that album here. It comes from a composition called Countdown which features similar chord movement to Giant Steps.

It’s certainly possible to believe that Coltrane himself believed that he couldn’t improve upon Giant Steps. Because from that point on in his career he went on to explore other aspects of jazz improvisation such as modal jazz and free jazz. And he never returned to the Bop style vocabulary of the Giant Steps album.
