Triads Exercise on Six String Bass – Bass Practice Diary – 11th June 2019
This is a triads exercise that I’ve adapted onto bass guitar from something that I saw the guitarist Pat Metheny play. The original version of the exercise came from this video.
He doesn’t start playing the triads until about 3 minutes into the video. And it isn’t clear if he’s improvising or playing an exercise that he’s previously practiced. But I thought it sounded great and it looked like a great way to practice triads and their inversions. So I adapted a short section of what he played onto my six string bass and I’ve turned it into an exercise.
Triads and their inversions
A triad is a three note chord. The obvious way to arrange a triad in root position is root, third, fifth. Then you can play two inversions, third, fifth, root and fifth, root, third.
But that’s not necessarily the best way to play them on fretted instruments like guitars and basses. In this exercise, when Metheny plays a root position triad, he skips the third and goes straight to the fifth. Then he plays the third up an octave, a tenth above the root note. So using this arrangement, the three inversions of the triads are root, fifth, third. Then third, root, fifth and finally fifth, third, root.
Below is an Ab major triad and a Bb minor triad arranged in this way on four string bass.
There are two other common types of triad, diminished and augmented. These are actually much simpler to play because they’re symmetrical. Meaning that they use the same interval over and over. Diminished arpeggios divide the octave up into four minor third intervals and augmented arpeggios divide the octave into three major third intervals. Which is why there are four inversions of the diminished triad below but only three of the augmented triad.
This is the exercise. It mostly uses the major triads and the inversions. But there are a few minor and diminished triads. There are no augmented triads in this exercise. I’ve written the chords on top to help you keep track of which chord you’re playing.
Chord Extensions on 4, 5 & 6 String Bass Guitars – Bass Practice Diary – 25th September 2018
I’ve done a few videos in the past about playing chords on the bass. This week I’m demonstrating a fairly simple approach you can use to playing jazz chord extensions. The system involves using two different voicings of 7th chords. Each using three notes, root, 3rd and 7th. Then adding chord extensions like 9ths, 11ths and 13ths as well as common alterations.
A Very Quick Guide to Jazz Harmony – 7th Chords
Chord extensions and alterations are synonymous with jazz harmony. 7th chords form the foundation of most jazz chords and I’m going to look at the three most common types of 7th chord. They are Major 7th, Minor 7th and Dominant 7th.
7th chords are four note chords, all of the chord types mentioned above contain root, 3rd, 5th and 7th. The root and 5th are the same in all three chord types, so the 7th chords are defined by the thirds and sevenths. Major 7th chords have a major 3rds and 7ths. Minor 7th chords have minor 3rds and 7ths and dominant 7th chords have major thirds and minor 7ths.
There are other types of 7th chords, but in this post I’m only going to look at these three types because they’re the most common.
When voicing extended chords it’s extremely important to know which notes to leave out. Regardless of whether you play 4, 5 or 6 string basses, you only have a finite number of strings. I recommend that you don’t try to cram every note from an extended chord into a chord voicing. It’s rarely a useful or practical approach.
The first note to leave out is the 5th, because it’s the same in each chord type. It doesn’t tell you anything about the chord. So, when I voice 7th chords, I voice them as three note chords, root, 3rd and 7th.
Assuming that you keep the root as the lowest note, that means you can voice a 7th chord in two different ways. The first way is with the 7th on top, as demonstrated in the three diagrams below.
The reason that I’ve voiced these chords on the 2nd, 3rd and 4th strings is so that I can use the first string to add a chord extension. These voicings work well for 9th chords. The 9th above my root note A is the note B played on the 16th fret of the first string. You can add this note to each of the chord types and you get these chord voicings.
There are two alterations you can make to the 9th in the dominant 9th chord. You can sharpen it to make an A7#9 chord or you can flatten it to make an A7b9 chord.
Voicing 7th Chords With the Third on Top
I stated previously that there were two ways I was going to voice the 7th chords. The first was with the 7th on top. Now I’m going to make the 3rd the highest note. I’ll play the root and 7th in the same place, but I’ll move the third up an octave, from the third string onto the first string.
In these voicings the 3rd string is not being used. So I can add a chord extension to the 3rd string. An obvious one to use is an 11th, because it sits comfortably in these chord shapes.
The natural 11th sounds good in a minor 7th chord. But, it doesn’t work so well on chords with major 3rds. So, for the major 7th chord I’ll add a sharpened 11th, which creates a lydian sound.
The sharpened 11th also works well on the dominant and minor 7th chords, and in these cases the sharpened 11th can also be described as a flattened 5th. So, I can create four new voicings by adding either a sharp or natural 11th to the 3rd string.
Chord Voicings for 5 String and 6 String Bass
All the voicings I’ve played so far can be played on 4 string bass. However, more strings means more potential chord voicings so I’m going to look at some voicings that will only work on 5 and 6 string basses.
First I’m going to take a couple of the 11th chords from the previous examples, and move the 11th up one octave. So, in the following voicings the 11th is the top note above the 3rd.
Finally I’m going to look at some voicings for 13th chords. The 13th is basically the same as a major 6th which is a note that can work on major, minor and dominant chords.
The voicings below are all dominant 13th chords. In each voicing the 13th is played as the highest note on the 1st string. It can be altered by flattening it as I’ve done in the second voicing. And, it can also be combined with the 9th, as I’ve done in the final voicing.
One big benefit of playing chord voicings on a 6 string bass is that you can play multiple chord extensions as I have in the final A13 voicing.
In a Sentimental Mood by Duke Ellington – Jazz Arranged for Fretless Bass and Acoustic Bass Guitar – Bass Practice Diary – 4th September 2018
I love to play jazz on my basses at home when I get the chance. I usually make my own backing tracks and practice by playing along with them. In this video I’ve laid down the chords of Duke Ellington’s In a Sentimental Mood on my acoustic bass guitar and played over the chords on my fretless Warwick Thumb SC.
In a Sentimental Mood
In a Sentimental Mood is one of those great jazz tunes that’s both simple and beautiful. It has a very lyrical melody and some simple but effective chord changes. It was written by Duke Ellington in 1935 and originally performed by his orchestra. But the version that I’ve been listening to was recorded by Duke Ellington with John Coltrane in 1963. I also like Ella Fitzgerald’s vocal rendition of the song, where she sings the melody with just a guitar backing her. I’ve tried to get some of the flavour of both versions in my video. In a Sentimental Mood is also a staple standard of Sonny Rollins sets. He seems to play it a lot and he’s done some wonderful versions of it.
The Warwick Thumb SC is not only the best fretless bass I’ve ever played, it’s the best bass I’ve ever played. If you’ve seen many of my other videos you’re probably quite familiar with this bass by now. But if you’d like more info, you can find it here.
Suspended and Major Chord Voicings – Bass Practice Diary – 31st July 2018
This week I’ve been looking for new and interesting chord voicings on my 6-string bass. Suspended chords tend to create a modern sound and I’ve demonstrated one particular voicing that I like and has proved to be quite versatile.
When I found this particular voicing I started moving it around to different positions and playing it over open strings, which created other chords, mostly major chords. What you see in the video is me improvising using this chord voicing.
It isn’t particularly structured practice, but that’s ok, because sometimes when you’re practising an impulse takes over and you just play for fun. That’s what’s happening in this video. And as soon as I’d shot the video, I pulled out my fretless Warwick Thumb SC to play a bit of melodic improvisation over the top.
Suspended chords or sus chords are chords that omit a third in favour of using either the second or fourth or both. The absence of a third makes the chords neither major or minor. It’s the third that defines whether a chord is major or minor. And sus chords have a neutral sound as a result of not having a third. Listen to Herbie Hancock’s Maiden Voyage for an example of the suspended chord sound being used in jazz.
The chord symbol for a C suspended chord can be written as Csus. I sometimes see it written as C11. I don’t like the 11 chord symbol because, although a 4th is the same as an 11th, the 11 chord symbol implies to me the presence of a third, dominant seventh and a ninth. So the sus symbol is more accurate.
Csus2 is C, D and G (root, 2nd, 5th), Csus4 is C, F and G (root, 4th, 5th). You can think of C7sus as Bb/C. The Bb, D and F from the Bb major triad function as the dominant 7th, 2nd and 4th and create a suspended sound when you play them over a C root note. You could also call the same chord C9sus because the 2nd and 9th are interchangeable in the same way that the 4th and 11th are.
The Opening Chord Sequence
The opening sequence in the video is played over an open A string until the final chord which is played over an open E. All of the voicings are built by playing an interval of a sixth between the D and G strings, and an interval of a second between the G and C strings. Try making your own chords using the same voicings. You can adapt them onto four and five string basses by playing over the open E string and voicing the chords on the A, D and G strings.
Due to the improvised nature of my performance in the video, many of these chords are no longer sus chords. Many of them are major chords. What started off as an exercise in finding suspended chord voicings became an improvisation using the same chord voicing against open strings.
The Chord Theory
The first chord in the opening sequence is a suspended chord, but the second has a major sound. It contains a C#. Which is the major 3rd of A. If you listen carefully in the video I don’t play the top note on the second chord. It would have been a D. I was improvising and I’ve no idea what I was thinking in the moment. But I may have thought that C# and D would clash, being a semi-tone apart. In hindsight I slightly regret this. Conventional jazz theory says don’t include a major 3rd and natural 11th in the same chord voicing. But I think it works in this context. So I’ve included the note in the TAB even though it’s not in the video.
The third chord creates a lydian sound with the sharp 11th D# and major 3rd C#. You can check out my video on lydian sounds by clicking here. The fourth chord creates a straightforward A major sound with an added 9th. And the final chord creates an E major/Esus sound. Again, I’ve included the major 3rd and natural 11th, which I think sounds cool. Even though the two notes clash if you play them simultaneously. Notice that I’ve finger picked each note individually to cut down on the impact of such clashes. The final note that I’ve included is tapped with my right hand index finger.
The Closing Sequence
The closing sequence simply uses the last two chords of the opening sequence and repeats them. I hope you have some fun with these chord voicings and you’re able to come up with some original chords.
