Quartal Chord Voicings on Bass Guitar – Bass Practice Diary 45

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.

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.

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.

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.

Bass Guitar Chords – Right-Hand Tapping Chord Extensions – Bass Practice Diary – 29th January 2019

Tapping notes with your right hand is a great way to extend your bass chords. I’ve seen lots of bassists do this, particularly in solos. It’s not as difficult as it looks and it works really well for playing extended harmonies. Even on a 4 string bass where it’s often hard to voice extended chords with just your left hand.

Bass Guitar Chords

This isn’t my first video about playing chords on the bass. So, if you’re new to this, then I’d highly recommend checking out some of my previous videos. Like this one, which is the first of a four part video I did on bass guitar chords.

Playing Chords on Bass Guitar Part 1

More recently I made this video about playing chord extensions on bass guitar.

Right-Hand Tapping

This video features a different approach to playing jazz chord extensions. By tapping the extensions with your right hand. Using this technique, you can really open up your chord voicings by playing harmonies in a completely different register to the notes you’re playing with your left hand.

I should start by saying that my tapping technique is basic. I don’t use tapping techniques a lot. In fact, these types of chords are pretty much the only places where I will use my right hand to tap chords. But I think that’s also the case for most bass players. Right-hand tapping is rarely a first choice technique for bassists, it’s an added extra that you can use on solos.

Having said that. I know that there are musicians for whom tapping is there principle technique, and they have much more advanced techniques using four fingers on their right hand, just like their left. My basic tapping technique involves hammering on, sliding and pulling off notes with my index, middle and ring fingers on my right hand. It’s all I need for what I do.

Diatonic Triads

Diatonic triads are just basic major and minor chords that you find in every key. (You could also include diminished and augmented triads but I’m just using major and minor here). The first four chords, in the key of D major are D, Em, F#m and G. Here is how I have voiced those chords with my left hand in this video.

D major triad

E minor triad

F# minor triad
G major triad

These triads form the basic chords onto which I can add my chord extensions with my right hand. With each chord, I start by playing each triad, plucking the strings with my right hand, Thumb plays 4th string, index plays 3rd string, middle plays 2nd string and ring finger plays 1st string. Or p, i, m, a, to use classical guitar terminology. None of these notes are tapped, they are fretted with the left hand in traditional style.

Chord Extensions

Start by adding chord extensions on just one chord. In this example I’ve added a major 7th to the D major triad making it a Dmaj7. The 7th is the only note tapped by the right hand.

D major 7th

Make sure you tap the note onto the 18th fret. If you tap in between the 17th and 18th fret, it won’t sound as clear.

In this next example, I’ve tapped a 9th, E, and slid the note up to the major third F#.

D major with added 9th

In this third example I’ve included the major 7th and the 9th.

D major 9th

Right-Hand Tapping Exercise

Once you’ve got used to the technique, try playing this exercise.

There’s quite a lot going on here, so I won’t write an exhaustive analysis. But here’s a quick guide.

Over the D triad I’m tapping major 7th, 6th, #11th and 9th. On the E minor I’m adding minor 7th, 11th and 9th. On the F# minor I’ve used minor 6th, minor 7th and b9th and on the G major triad I’ve played similar extensions to the D major. Major 6th, 9th, major7th and #11th.
