6-String Bass Duet – Fretless & Fretted – Bass Practice Diary 154

6-String Bass Duet – Fretless & Fretted – Warwick & Overwater – Bass Practice Diary – 20 April 2021

It seems that I’m in a contemplative mood after more than a year of lockdowns. There have been virtually no opportunities to play with other musicians. So, I’ve been recording on my own a lot. Recently, I’ve been trying to arrange material for these two basses, probably my favourite two basses. A fretted Overwater Hollowbody 6-string and a fretless Warwick Thumb SC 6-string bass. This arrangement came out of some Keith Jarrett improvisations that I was transcribing.

The Chord Progression

I’ve always felt that Keith Jarrett is a wonderful improviser. He regularly improvises entire solo piano concerts and he seems to effortlessly incorporate both jazz and classical influences. What I’ve played here is not exactly a transcription, but my own arrangement based on some of the harmonic ideas that I transcribed.

Here are diagrams for the chords I’m using. The diagrams are all written for 6-string bass in standard tuning. Don’t take the chord names too seriously. I considered not including any names above the chords, but I thought they might be helpful for locating the correct positions on the neck.

It’s hard to find accurate names for some chord shapes. For example, look at the last chord. It includes two D’s, an Ab and an Eb. It’s like an Ab Lydian triad (root, #4th & 5th) in the first inversion. So, I’ve called it Abmaj7(#11)/D. However, it doesn’t have a major third, C. The major 7th G is not in the chord either, but it is played by the fretless bass as a melody note. So, the chord symbol isn’t very helpful.

So, some of the chord symbols are helpful and others aren’t, don’t take them too seriously. I’m fairly certain that Keith Jarrett doesn’t think about chord symbols when he plays and I certainly didn’t think about chord symbols when I played this. I didn’t put the names on the chords until after I shot this.

In the performance, I played the chord sequence through twice in its entirety. Also, I used the first two chords played repeatedly as both an intro and an outro.

Improvisation Strategies on 6-String Bass – Part 2: Naima – Bass Practice Diary 118

Improvisation Strategies on 6-String Bass – Part 2: Naima on Fretless Bass- Bass Practice Diary – 14th July 2020

Naima by John Coltrane has a beautiful but challenging chord progression. Last week, I featured a video demonstrating how I play the chords. But the story isn’t complete without looking at how to improvise over those chords. So, this week I’m demonstrating an improvisation strategy for playing over the part that I find hardest to improvise on.

Modal Chord Progression

Most improvisers think of Naima as being a modal composition. Meaning that they think of each chord as representing the sound of a scale or mode. This is different to the diatonic approach that I looked at in my Improvisation Strategies: Part 1 video. In that video I looked at a I-VI-II-V sequence of chords where each chord represented a different degree in the key of Bb major.

When you hear improvisers analysing how to play Naima, usually you’ll hear them say something like, ” play this scale or mode on that chord, and this scale or mode on that chord etc”. And it’s not wrong to think about the progression as a sequence of modes. If you listen to Coltane playing Naima, you can definitely hear that he is playing complete modes quite often.

However, when I’m coming up with an improvisation strategy, I prefer to think in a more economical way. I want to start with something small that I can expand upon. I want to zero in on the notes that I feel best spell out the sound of the harmony. Remember that you can come up with multiple strategies for playing on the same progression. So when you zero in on just a few notes, you’re not limiting yourself, you’re actually creating the potential for much more variation. Because if you start by using all of the notes from the implied scale or mode, then it doesn’t leave as much scope for expanding and using different harmonic ideas.

Naima Improvisation Strategy

Last week I wrote about how I think of all of the chords as being major 7th chord voicings over a pedalled bass note. I won’t repeat myself, so if you’re interested in the chords check out last week’s post.

This four bar section of the harmony comes from the second half of the B section. The chord symbols that I’ve written are different from the Real Book changes, (even when you allow for the change of key). But I think that my changes reflect the harmony that Coltrane was using fairly closely. I wouldn’t recommend getting bogged down in what the chord symbols are. When I was working out how to play this piece, I wasn’t thinking about chord symbols, I was just trying to recreate the sounds that I was hearing and I put the chord symbols on afterwards. So, here is my improvisation strategy for this short four-bar sequence, I’ve picked out five notes to use on each chord.

Improvisation Strategies on 6-String Bass – Part 1: I VI II V – Bass Practice Diary 116

Improvisation Strategies on 6-String Bass – Part 1: I VI II V – Bass Practice Diary – 14th July 2020

I often get asked questions about how to improvise. I’ve noticed that people are usually looking for a simple answer, like “you just need to know the right scale.” However, if you’re reading this, you probably already know that it isn’t that simple. To become a fluent improviser, you should work on lots of different improvisation strategies. As part of my own practice, I regularly try to find new and different ways to play through chord progressions that I’ve played on many times. To help demonstrate what I do, I’m presenting one improvisation strategy that I’ve come up with on a I-VI-II-V chord progression.

Improvisation Strategies

Before we get into the specifics of this particular strategy, I should say that my end goal is the same for any improvisation strategy. That goal is to be able to improvise all over the fretboard. So, when I practice a strategy, I’ll practice it in multiple positions until I can connect up the notes all over the entire fretboard.

In this particular strategy, I’m looking at jazz improvisation on a I VI II V progression in Bb major. Although I would recommend practicing any strategy in multiple keys. The chords in the key of Bb major are Bb – G7 – Cm7 – F7. Notice that Chord VI is played as a dominant chord rather than a minor 7th chord. This is so that it leads nicely to the II chord. It is a very common chord substitution in jazz (and other styles).

A very simple approach to improvising on a I VI II V progression would be to just play a Bb major or major pentatonic scale. The problem with that as a strategy, is that it ignores the B natural in the G7 chord. So most jazz musicians will prefer to play something different for every chord. This is often referred to as “spelling out the harmony”. So what I’ve done is chosen four different notes for each chord. Each set of four notes is specific and unique to each chord.

Why Play Four Notes for Each Chord?

Normally when a I VI II V is played in the context of a jazz standard, the entire progression is played over two bars. Meaning that each chord lasts for just two beats. With just two beats on each chord, four notes provide more than enough options to fill up the space. If you’re strategy was to use an entire scale, even a pentatonic scale, it would be more notes than you need. It would make improvising on the progression harder than it needs to be.

In choosing the four notes for this strategy, I used arpeggios. You don’t have to use arpeggios, you can use any four notes that you like the sound of. But I think that arpeggios are fundamental to the sound to jazz improvisation, so that’s why I’m using them. I could have simply used a Bb major arpeggio for the Bb major chord and a G7 arpeggio for the G7 chord etc. That would certainly have spelled out the harmony, but it would also probably have sounded a bit predictable. Instead, I opted to play a Dm7 arpeggio on the Bb major chord. The notes of the Dm7 arpeggio played over a Bb major chord create the sound of a Bb major 9 arpeggio without the root note.

By making this substitution, I was thinking of the progression as III-VI-II-V, Dm7 – G7 – Cm7 – F7. This actually simplifies things a lot because it leaves me with two minor 7 chords and two dominant 7 chords. I can use the same strategy for both minor 7 chords and the same strategy for both dominant 7 chords. So I used minor 7 arpeggios on chords III and II and on chords VI and V, I used diminished 7 arpeggios starting on the third of each chord. Bo7 on the G7 chord and Ao7 on the F7 chord. (o in this case means diminished).

Putting the Strategy Into Practice

The best way to put any improvisation strategy into practice is with a backing track. You can find free I VI II V backing tracks on the internet. It’s always a good idea to start slowly, and you can start by just playing the notes you’ve prepared over the chords as an exercise. As you get comfortable doing that you can start to improvise lines that connect up the chords by adding passing notes. Here are three examples that I’ve written out to demonstrate.

The passing notes could be chromatic notes or scale tones. Or to put it another way, they could be literally any note that helps to connect the lines. If you use the four note patterns that you’ve prepared as the structure for your lines, then adding passing notes here and there, won’t interfere with the musical sense of the lines.

There are so many ways that you can vary this one simple idea. You can (and should) practice it in multiple positions on the neck. Here is another position to get you started.

Then try to improvise by connecting up the different positions that you’ve practiced.

Then you could try practicing the same ideas in different keys. You could then try using the same chords, but changing the four note patterns. And finally you could try playing similar patterns on different chord progressions. When you get into practicing these kind of ideas, there really is a lot of different ways you could be doing it. And the more different strategies that you practice, the more fluent your improvising will become.
