Passion Dance by McCoy Tyner on fretless 6-string bass – Bass Practice Diary 99

Passion Dance by McCoy Tyner on fretless 6-string bass – Bass Practice Diary – 10th March 2020

One of the most memorable musical moments in my life was seeing McCoy Tyner play live at the Jazz Cafe in London in 2003. I was 19 years old and I had recently got very into the John Coltrane Quartet. My parents had given me A Love Supreme on CD as a 19th birthday present. The thought that I was going to watch the pianist from that album play live, was almost too exciting!

I arrived when the doors opened (about 3 hours before the gig started) to get myself a position with the best view. I literally sat about a metre from McCoy Tyner’s right hand as he played an absolutely burning set with his trio, which at that time included the unbelievably talented Charnett Moffett on bass and Eric Harland on drums. It’s a memory I will never forget. At that point in my life I had never heard music played with that level of intensity by a small acoustic jazz band.

I’ve heard many musicians imitate McCoy Tyner’s style over the years. But I’ve never heard anyone who could do it like him. I saw him live many more times after that, always in concert halls rather than jazz clubs. I even met him on one occasion. But it’s that first gig in a jazz club in London that will always stick in my memory as one of my happiest musical memories. It was one of the first times that I’d seen “the real thing” up close and it had a huge impact on me.

It was with great sadness that I heard about McCoy Tyner’s passing this week at the age of 81. He was a truly unique musician, and his influence on modern jazz is enourmous.

Quartal Harmony

McCoy Tyner is best known for the sound of quartal harmony. That’s when you arrange chord voicings in fourth intervals. It’s a very distinctive sound, and instantly recognisable in modern jazz. Passion Dance uses that quartal sound, and is a great example of McCoy Tyner’s signature sound. My rendition certainly doesn’t capture the intensity with which McCoy Tyner used to play it. But I wanted to put my own tribute out for a great musician who influenced me massively.

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.
