Jazz Chord Extensions for Bass Guitar – Bass Practice Diary 23

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.

Example 1 Chord Extensions
7th Chords: Root, 3rd & 7th

9th Chords

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.

Example 2 Chord Extensions
9th Chords: Root, 3rd, 7th & 9th

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.

Example 3 Chord Extensions
Altered 9th Chords

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.

Example 4 Chord Extensions
7th Chords: Root, 7th & 3rd

11th Chords

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.

Example 5 Chord Extensions
11th Chord Voicings: Root, 11th, 7th, 3rd

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.

Example 6 Chord Extensions
11th Chords: Root, 7th, 3rd & 11th

13th Chords

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.

Example 7 Chord Extensions
Dominant Chord Voicings with 13ths

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.

 

 

 

 

Playing Jazz on Fretless Bass and Acoustic Bass Guitar – Bass Practice Diary 20

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 Basses

The video features two of my favourite basses. The acoustic bass is an Alien Deluxe 6 string acoustic bass guitar. If you’d like to learn more about this bass you can check out my solo arrangement of the jazz standard Autumn Leaves. Or you can check out this demo that I made a few years ago when I first owned the bass.

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 15

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.

If you’re interested in that kind of melodic improvising with fretless bass then check out these two recent posts. Use Fretless Bass to Play Jazz Solos and Melodies and Charlie Parker Tunes on Fretless Bass Guitar.

What Are Suspended Chords?

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

Suspended and Major Chord Voicings Opening Sequence
Suspended and Major Chord Voicings Opening 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.

 

 

Oteil Burbridge Chord Voicings – Bass Practice Diary 3

Oteil Burbridge Chord Voicings – Bass Practice Diary – 8th May 2018

This week I’ve been working on chord voicings based on a chord that I heard Oteil Burbridge play. Check out this video and the chords are written out at the bottom of the page.

Oteil Burbridge is a wonderful bass player. A fellow 6-string player with an incredible grasp of melody and harmony. If you’re not familiar with his playing I would highly recommend checking him out. When I heard him play the chord I demonstrated in the video I thought it had a really interesting and modern sound.

Intervals and Keys

When I’ve found a really cool voicing like this one, I like to try and find every possible permutation of it. A great place to start is with major keys.

Every chord is a sequence of intervals. See my video on intervals here. There are four  notes in this particular chord voicing which creates three intervals. Starting at the lowest note you go up a fifth to the next note. Then a second to the third note and then another fifth to the fourth and final note.

So I started by working out every permutation of these three intervals within a major key. Each key gives you seven chords. I’ve demonstrated these in the video in the key of F major. So I’m using only the notes F, G, A, Bb, C, D, E.

If you want to take this a step further you could apply the same process to other scales, such as harmonic minor, melodic minor or diminished.

You could also work out every possible mathematical permutation of a fifth, a second and a fifth. A fifth could be a perfect fifth or a flat fifth and a second could be a major second or a minor second. Arguably you could include a sharp fifth and a sharp second as well which would dramatically increase the number of possible permutations. However, I would prefer to think of a sharp second as a minor third and a sharp fifth as a flat thirteenth.

They may not all sound great and some of them might be quite tough to play. However, it would be a great exercise in working out harmony.

Here are the seven chords I worked out in the key of F major using the Oteil Burbridge chord voicing.

Playing Chords on the Bass – Part 4 – Chord Extensions

In Part 4 we’re going to look at chord extensions.

In this video lesson you’re going to learn how to play chords with chord extensions on the bass.  I’ll also explain what notes you can leave out and why, in order to make your chords sound more interesting.

What are chord extensions?

Extended harmony is where chords get a lot more interesting sounding but it’s also where the theory gets more complicated. Chord extensions are notes that we can add to basic chords like triads. Having established how to play triads in Part 3, we can now look at adding chord extensions to them.

The most common chord extension by far is the seventh. In Part 3 we looked at how triads are made up of a root, a third and a fifth. And there is an interval of a third between each of these notes. In order to make a triad into a seventh chord we just continue this pattern of stacking intervals of a third. We add a note that is a third above the fifth and we call this note the seventh. Seventh chords have four notes in them root, third, fifth and seventh.

Four types of seventh chords

If you watched my video about “Intervals” then you’ll know that there are two types of sevenths, major and minor just like there are major and minor thirds. Fifths however are not major or minor and so the fifth is the same in both major and minor chords. For this reason, it’s the third and seventh notes of each chord that define what type of chord it is.

For example if you have a chord with a major third and a major seventh in it, it’s called a major seventh chord and a chord with a minor third and a minor seventh is called a minor seventh chord. The word used to describe a chord that has a major third and a minor seventh in it is “dominant” and dominant seventh chords are very common.

The chord symbol for a dominant seventh chord is just the number 7 (eg. G7, A7, C7 etc.) minor seventh chords are written m7 (eg. Gm7, Am7, Cm7 etc.) and major seventh chords can be written a number of ways such as with a small triangle or sometimes with an upper case M, but most commonly they are written maj7 (eg. Gmaj7, Amaj7, Cmaj7 etc.)

These three types of seventh chords are by far the most common but there are others that I’ve also listed at the end of Example 1. For example, a chord with a minor third and a major seventh is called minor with a major seventh (min/maj7).

What notes can you leave out?

When we play extended chords we usually can’t play all the notes within the chord because we only have a finite number of strings on the bass. The more chord extensions we have means the more options we have, but it also means the more decisions we have to make in terms of what notes to leave out. In the case of seventh chords the decision is simple, I’ve already mentioned that the fifth is the same for major and minor chords so the fifth doesn’t fulfill a very important function in the chord (unless we alter it as in diminished and augmented chords). So if we leave out the fifth we have three notes left, the root, third and seventh.

Example 1 demonstrates two different ways of voicing major seventh, dominant seventh, minor seventh and minor with a major seventh chords. The first way is to play the root on the A string, the third on the D string and the seventh on the G string. The second way is to play the root on the E string, leave out the A string and play the seventh on the D string and the third up an octave on the G string.

Video 4 Example 1 Chord extensionsAltering the fifth

Just because the fifth is the same for both major and minor chords doesn’t mean we can’t alter it. You can flatten the fifth (lower by a semi-tone) to give you a diminished chord or sharpen it (raise it by a semi-tone) to give you an augmented chord. In order to play a diminished or augmented chord you need to include the fifth because the fact that it’s been altered makes it a key element in the chord. That is why I have included all four notes in the augmented and diminished examples in Example 1.

Sixths

Another common chord extension that we can use instead of a seventh is a major sixth. We can add a major sixth to a major triad or a minor triad. The chord symbol for a major chord with a major sixth is just the number 6 (eg. G6, A6, C6 etc.) and the chord symbol for a minor chord with a major sixth is m6 (eg. Gm6, Am6, Cm6 etc.) Example 2 demonstrates how to play these two types of chords. Again, I’ve left out the fifth in both cases.

Video 4 Example 2 Chord extensions

Harmonising D major in seventh chords

If we harmonise any major scale into seventh chords we get seven different chords, two major seventh chords (chords I & IV, three minor seventh chords (chords II,III & VI), one dominant seventh chord (chord V) and one half-diminished chord (a chord with a minor third, a minor seventh and a flattened fifth) (chord VII). In example 3 I’ve harmonised a D major scale into seventh chords.

Video 4 Example 3 Chord extensions

Ninths

After the seventh, the next extension we can add to a chord if we keep stacking intervals of a third is a ninth. A full ninth chord has five notes in it, root, third, fifth, seventh and ninth. Example 4, demonstrates how to play a few common ninth chords by adding a ninth to a major seventh chord, a dominant seventh chord, a minor seventh chord and even a major sixth chord. As before I’m leaving out the fifth in each chord.

Video 4 Example 4 Chord extensions

More chord extensions

If we keep up this idea of stacking intervals of a third we end up with an eleventh and then a thirteenth. By the time you reach the thirteenth you have seven notes. Most scales have seven notes. So a seven note chord would effectively be equivalent to playing all the notes from a scale simultaneously. Which is usually a bad idea. Also, you can alter (either sharpen or flatten) the upper extensions (ninth, eleventh and thirteenth). Just like I altered the fifth earlier. This gives you a huge amount of options in terms of extending chords.

So, we have to exercise some judgement over which chord extensions we can add to which chords. And that all comes down to what we think sounds good. For example, you normally wouldn’t want to add an eleventh to a chord with a major third in it (major or dominant). Because the eleventh clashes with the third but you can add a sharpened eleventh. If you want to add an eleventh to a major chord then you would normally leave out the third. That would change the chord to what we call a “sus” chord. A sus chord is a chord that omits the third and usually replaces it with the fourth. The fourth is the same note as the eleventh. Check out my video on “intervals” if you don’t understand why the fourth and the eleventh are the same note.

Example 5 demonstrates some common chord extensions that we can play over major or minor chords on the bass.

Video 4 Example 5 Chord extensions

Chord extensions on 5 and 6 string basses

For Example 6 I’ve had to switch onto my six string bass to play some of these extensions. The ability to play more extended harmony is one of the main reasons I choose to play six string basses. If you don’t have a six string bass, many of these chords can be adapted onto a five string bass.

Playing Chords on the Bass – Part 3 – Triads

Learn to Play Chords on the Bass – Part 3 – Triads

In this video lesson you’ll learn how to play triads on bass guitar. There are four different types of triad. I’ll explain what they are and then how to play them.

Triads, what are they and how do you play them?

In part 3 we’re going to look at how to play triads on the bass. They are simple three note chords that form a foundation for a lot of extended harmony. Before we can go on to explore chord extensions it’s really important to understand triads.

There are essentially four types of triad. Major, minor, diminished and augmented. So, example 1 contains an example of each triad. In this example they all have the root note C.

Video 3 Example 1 TriadsOf these four, major and minor are by far the most common and will be the ones we use the most.

Harmonising scales using triads

We can harmonise scales into triads. In part one we harmonised scales into intervals of a third. A triad is two intervals of a third stacked together. By which I mean, you take a root note, find a note that is a third above it and then another note which is a third above again. The three notes of a triad are often referred to as the root, the third(an interval of a third above the root) and the fifth (an interval of a third above the third and an interval of a fifth above the root).

You’ll find that when you harmonise a major scale into triads you’ll get seven chords, three major (chords I, IV & V), three minor (chords II, III and VI) and one diminished triad (chord VII). In example 2 there’s a G major scale harmonised into triads played in root position. Meaning that the root note is the lowest of the three notes.

Video 3 Example 2 TriadsIn the previous example we refer to these chords as root position because we’ve arranged each triad in a neatly stacked order with the root at the bottom and the third and the fifth stacked on top of it. If we change the order of these notes to make either the third or the fifth the lowest note then we have what we call an “Inversion”. There are only two possible ways to invert a triad. First of all put the third at the bottom as in Example 3.

Video 3 Example 3 Triads

Triad inversions

Then put the fifth at the bottom as in Example 4.

Video 3 Example 4 TriadsExample 5 is an E major scale harmonised in first inversion triads.

Video 3 Example 5 TriadsFinally example 6 is a D major scale harmonised using the second inversion.

Video 3 Example 6 Triads

Harmonising minor scales

If you harmonise a melodic minor scale into triads you get two minor chords, two major chords, two diminished chords and one augmented triad. So, in example 7 there’s a G melodic minor scale harmonised using root position triads.

Video 3 Example 7 Triads

Now move on to Playing Chords on the Bass – Part 4 – Chord Extensions. You’ll learn how we can add extensions to the triads so you can make more interesting sounding chords.

 

Playing Chords on the Bass – Part 2

Chords on the Bass – Part 2

In this second part in my series of videos about playing chords on the bass, we’re going to continue looking at how we can make chords by playing double stops (two notes played at the same time) over open strings. In Part 1 we harmonised scales into intervals of a third and in Part 2 we’re going to see how we can get a whole new set of sounds and chords by changing the interval we use to harmonise our scales.

Intervals

If you’re not sure what an interval is or how we play intervals on the bass then check out my video called Intervals which is also available on this site and it will explain everything.

In Example 1 I’m playing a C major scale harmonised into intervals of a fourth.

Part 2 Example 1 Chords on the Bass

In Example 2 I’m playing the same C major scale played in fourths. I’m playing it over an open A string. Then in the following examples I’m still playing a C major scale over an open A string. However, I’m changing the interval that I’m using to harmonise the scale. In Example 3 I’m harmonising the C major scale in fifths and in Example 4 I’m using sixths. You can hear that each different  interval gives us a different sound even though I’m harmonising the same scale over the same note.

Video 2 Examples 2, 3 & 4 Chords on the Bass* I’ve marked some chords * in the above examples because they don’t contain thirds. The Am7 and Am9 chords could also function as A7 and A9 because they don’t contain the note C. Which is the minor 3rd. I’ve labeled them as minor chords because if we were to add a third in this key it would be a minor third C. Not a major third C#. The G9/A chords in Examples 2 & 3 also don’t include the 3rd B but again I’ve labeled them according to what they would be if we added a 3rd in this key. The same is true for the chords marked in the examples below.

Fourths, Fifths and Sixths

The next examples are a similar idea. Only this time I’m harmonising a D major scale and playing it over an open E string. This gives us a Dorian sound. In Example 5 I’m harmonising the scale in fourths. In Example 6 I’m using fifths and in Example 7 I’m using sixths. 

Video 2 Examples 5,6 & 7 Chords on the BassNotice how in Example 7 using the open E string instead of the open A string gives us a different option for fingerings when we play the scale in sixths. We can now play the lower of the 2 notes on the A string. The higher note on the G string while we leave out the D string altogether.

These examples are just a small demonstration of some the sounds that you can come up with using this idea. It wouldn’t be impossible to list here all the possible variations you can achieve by harmonising scales over open strings. So, I really want to encourage you to experiment and come up with ideas of your own.

A melodic minor in sixths

Before I leave you, I’m going to share one more idea. Here’s what the A melodic minor scale that I introduced at the end of Part 1 sounds like when you harmonise it in sixths and play it over an open A string.

Video 2 Example 8 Chords on the BassNow move on to Playing Chords on the Bass – Part 3 – Triads. You’ll learn how we can add extensions to the triads so you can make more interesting sounding chords.

Playing Chords on the Bass – Part 1

Can You Play Chords on Bass Guitar?

I love the sound of chords played on a bass and I use chords a lot in my playing. Apart from just sounding great, practicing chords on the bass has many benefits. The main one is that it really helps you to learn harmony on the fretboard.

 

Start by Playing Two Notes at a Time

A good place to start is with double stops (playing 2 notes together). In this first example I play an A major scale two notes at a time using intervals of a third. This gives us the foundation of seven different chords.

Click on the examples to make them bigger.

Example 1 Chords on the BassIf you play through my written examples, I would encourage you to not just play them the way they are written, its a ok to start like that but once you feel comfortable with the notes I would recommend changing the order in which you play them as this will help you to experiment and come up with musical ideas of your own. In this second example I play the same notes I played in example 1. However, I also play an open A string with each chord.

Add Open Strings to Make Chords

Example 2 Chords on the BassAs you can see from the chord symbols written above the notes, adding this open A string changes some of our double stops into chords. I’ll explain below why I have used these chord symbols. If you don’t want to know the chord theory then please feel free to skip onto the next examples.

Chord Harmony Explained Chords I, II and III

The first chord is still A major but the second chord becomes an inverted B minor 7 chord because the A is the minor 7th relative to the B while the D played on the 7th fret of the G string is the minor 3rd. The third chord is now A major where before it was C sharp minor. This is because the C sharp played on the 11th fret of the D string is the major 3rd relative to our open A string and the E played on the 9th fret of the G string is now functioning as the 5th. These three notes make a simple A major triad (A, C sharp and E) more commonly just written as A.
Chord IV

The fourth chord is now an inversion of a D major chord. It’s also a simple triad because there’s a D on the 12th fret of the D string and an F sharp on the 11th fret of the G string. F sharp is the major 3rd relative to D and the open A sting is the 5th relative to D. So these 3 notes make up a D major triad but it’s an inversion because D is not the lowest note.  A is the lowest note, so we call the chord D over A.

Chord V
I think of the fifth chord as A major seventh even though it doesn’t contain the major 3rd note, C sharp which is normally found in this chord. It does contain the 5th E and the major 7th G sharp. It’s OK to sometimes leave notes out of chords. On the bass, if we are dealing with extended chords (chords with lots of notes) we will have to leave some notes out so in this case the chord can still function as an A major seventh chord even without the C sharp.
Chords VI and VII
The sixth chord is still F sharp minor as it was in example 1. Only now we call it F sharp minor over A because the open A string is now the lowest note. The seventh chord I have called A major ninth because the G sharp played on the 18th fret of the D string is the major 7th relative to A. The B played on the 16th fret of the G string is the 9th. Normally in a full A major ninth chord you would have a C sharp (the 3rd) and an E (the 5th), but the chord can still be thought of as A major ninth.
If you are struggling to understand all this explanation of the chord symbols don t worry too much. The most important thing is that you learn what they sound like so you can be creative with them.

Change the Open String

In example 3 I still play the same notes as example 1 only now I play an open E string with each chord. This gives you a different sound to example 2 and changes the chords, they’re now mixolydian. This is basically what you get when you play an A major scale over an E note.

Example 3 Chords on the Bass

Change the Key

Now in the next examples I’ll change things slightly. I’m going to stop using the notes from the A major scale that we worked out in example 1. Instead, in the following examples I’ll use the notes from a G major scale (example 4), F major scale (example 5), E major scale (example 6) and C major scale (example 7), and play each of them with an open A string.

Examples 4, 5, 6 & 7 Chords on the BassThese examples are meant to demonstrate the different sounds you can achieve on your bass by harmonising different major scales over a single bass note. In this case the single note was our open A string. I’ve added the Greek names for the modes (Dorian, Phrygian, Lydian and Aeolian) to the examples above for your reference.

Learn the Sounds and Come up With Your Own Chords

The examples are certainly not a complete list of all the modes. I’ve simply presented them here so you can take the idea and experiment to come up with your own ideas. The most important thing, as with everything we practise, is to learn the sounds. Once the sounds are in your head and the notes are under your fingers then you’ve achieved the most important target. Learning the names of the chords and the modes is useful, but not nearly as important as learning the sounds they make.

I’ve added one last example here to give you an idea of something slightly different. All my previous examples have used a major scale. In this example I’m using a scale called the melodic minor scale. Try this out and see if you can come up with something interesting.

Example 8 Chords on the Bass* I’ve labeled the 5th and 7th chords here Amaj7 and Amaj9 because that’s what I’ve called the same chords in previous examples. As I mentioned before, neither chord includes a major 3rd but both chords include the note G sharp which is the major 7th relative to A and so they can both function as an A major chord. It is however important to note that the scale I’m harmonising in exercise 8 is an A melodic minor scale. So, if I add the 3rd to either chord then it’s a minor 3rd, not a major 3rd. Then the full chord would be called A minor with a major seventh.

Now move on to Playing Chords on the Bass – Part 2. You’ll learn how we can make chords by using intervals of 4ths, 5ths and 6ths.
