The Altered Scale – Bass Practice Diary – 16th April 2019

Jazz musicians love to play on dominant 7th chords. And the altered scale is a really important scale to practice if you want to create a jazz sound when playing on these 7th chords. I think that using the altered scale is often perceived as “advanced” harmony. But, as with most things, it’s easy when you understand it. So, here’s my very quick guide to using the altered scale on bass.

What is the altered scale?

The altered scale is a mode of the melodic minor scale. Meaning that it contains all of the same intervals as a melodic minor scale. The altered scale is essentially what you get when you play a melodic minor scale starting finishing on the 7th note of the scale.

So, what’s a melodic minor scale? It’s basically only one note different from a major scale. If you take a major scale and change the major 3rd to a minor 3rd, you have a melodic minor scale.

Here’s the notes of an F major scale.

And here are the notes of an F melodic minor scale.

F melodic minor scale
F melodic minor scale

Notice that the only difference is the third note. It’s an A natural in the major scale and an Ab in the melodic minor.

If you play the notes of an F melodic minor scale but use E (the 7th note) as the root note. You would be playing an E altered scale.

When you think about the notes of the F melodic minor with an E as the root note, it creates these interval relationships to the root note.

E altered scale
E altered scale

The 3rd of E7 would, of course, be written as G# not Ab. But the altered scale creates some interesting theoretical anomalies like that. Because the major 3rd note (Ab/G#) is actually the 4th note of the scale.

How do you use the altered scale?

As I mentioned at the start, the altered scale works really well on dominant 7th chords. You can think of the altered scale as being a kind of extended dominant 7th arpeggio with lots of chromatic alterations.

The scale includes the root, major 3rd and dominant 7th notes which are the fundamental ingredients of a dominant 7th arpeggio. But the other four notes are all chromatic alterations of some kind. Hence why it’s called the altered scale.

You can alter chord tones and extensions by moving them one semi-tone up or down. The 5th of E7 is B natural, but in the altered scale the 5th has been flattened to Bb. So the altered scale could be used on an E7b5 chord.

The 9th can be altered by sharpening or flattening it. The altered scale uses both alterations. So you could use it on an E7b9 or an E7#9 chord. The final alteration is a b13.

So you can use the altered scale to play on any of these altered dominant chord types. And you will sometimes see the chord symbol E7alt. Which implies a chord that could include any or all of these alterations.

So if you want to start using this altered dominant sound on your dominant 7th chords. Then start to think about using a melodic minor scale that starts one semi-tone above the root of the chord. So, if you’re playing on a D7 chord, think Eb melodic minor. For A7, thing Bb melodic minor, for G7 think Ab melodic minor, for B7 think C melodic minor etc.

Use the Diminished Scale to Play Jazz – Bass Practice Diary – 6th November 2018

This week I’ve been practising using diminished sounds to play on dominant 7th chords in jazz. If you want to bring a more jazz sound to your playing, using the diminished scale is a great way to do it. Because it creates an interesting series of inside and outside notes when played on dominant chords.

What is the diminished scale?

The diminished scale is what I would call a symmetrical scale. It sounds like it should be something very complicated but it’s actually very simple. In many ways it’s even more simple than a major scale.

Symmetrical scales are scales that use the same intervals repeatedly. In the case of a diminished scale the intervals are a half tone (semi tone) and a whole tone. Symmetrical scales are also called modes of limited transposition or fixed transposition, which sounds even more complicated. But it still isn’t. It simply means that there are a very limited number of different ways you can transpose the scale. For example, because of the repeating intervals a G diminished scale is the same as a Bb diminished scale and Db and E diminished scales. So the idea of playing in 12 keys is a bit redundant. Another example of a mode of limited transposition is the whole tone scale. You can also use the whole tone scale to play on dominant 7th chords, but that’s another video for another day.

There are only two different ways you can play a diminished scale, you can either start with a half tone or you can start with a whole tone. After that it just repeats the same patterns over and over. Which makes it quite easy to play, as I said before, in many ways easier to play than a major scale.

Here is an example of an arpeggiated diminished scale pattern that I featured in the video.

"Arpeggiated

How to practise a diminished scale

In the video I’ve used the example of a Bb7 chord. Here is a diminished scale starting on a Bb and beginning with a half tone.

HalfWhole Diminished Scale Starting on Bb
Half/Whole Diminished Scale Starting on Bb

I don’t always think about the scale starting on the root note. Often I will use the major third (D natural in this case) as a jumping off point. And in that case I will think of the scale as starting with a whole tone.

Another approach that I use is to start on the #9 or minor third. In this case Db. In this case the first two notes of the scale will be the minor 3rd (an outside note) resolving to the major third (a chord tone). This is a real signifier of the blues and it will help give your diminished licks a bluesy flavour.

How to apply the diminished scale in jazz

As I’ve previously mentioned, the diminished scale most commonly gets applied to dominant 7th chords in jazz. Here is the same Bb half/whole scale written out with the intervalic relationships to a Bb7 chord written over each note.

"Bb7

As you can see, the scale gives you all of the standard chord tones in a Bb7 chord. Root, major third, 5th and dominant 7th. However, it also includes one unaltered chord extension, the 13th, and three altered chord voicing, b9, #9 and #11. It’s these altered extensions that give the diminished scale a jazz flavour when you play them on a dominant 7th chord.

The best way to demonstrate this is by playing a jazz blues, because the blues uses dominant 7th chords a lot. I’ve transcribed a chorus of blues solo that I improvised in which I was using both the diminished sounds and the more traditional blues sound of the blues scale.

Playing Jazz With Three Different Basses – Bass Practice Diary 27

Jazz on Three Basses – Fretless Bass, Double Bass & Acoustic Bass Guitar – Bass Practice Diary – 23rd October 2018

This week I’ve made a very quick video to demonstrate the bass as an instrument. Specifically, it’s potential to play more than just bass lines. So, I’ve played a jazz standard on three different basses. Two of them are fretless, two of them are acoustic, two of them have six strings and only two of them are bass guitars! Read on to find out more!

If you’ve followed my previous posts, you’ve probably realised by now that I don’t feel that bass guitars should be restricted to playing only bass lines. My instrument is the bass guitar. And the irony is not lost on me that in this video, all of the harmony is played on bass guitars except the bass line. Which I’ve played on an upright acoustic bass.

The Bass Line played on Double Bass (Upright Bass)

The reason that I’ve done this is not because I think I’m a good upright bass player. I don’t think that. I don’t have time to practice the upright nearly enough. My upright bass skills will never be better than average at best. The reason is because it’s the traditional role in jazz for the acoustic upright bass to take the bass line. And I know from years of experience, that if you try and play jazz gigs on bass guitar, acoustic bass guitar or even electric upright bass, you will very often be treated as the guy who is standing in because the band couldn’t book an acoustic double bass player.

I started to study upright bass when I was already at music college, and I did it with the aim of getting more jazz gigs. And it worked! For a while I was playing a lot of jazz gigs in London with my upright bass. But I very quickly stopped enjoying it. It’s a very difficult instrument to transport, especially when it’s impossible to park in Central London. The gigs didn’t tend to pay very much and the practice that I was having to put into the upright bass was taking away from time spent with my first instrument, the bass guitar.

So I gave up doing gigs on upright bass and I started telling people who were calling me for jazz gigs that I could do gigs on Electric Upright Bass (much smaller and more portable), but not acoustic. Needless to say, the jazz gigs dried up almost instantly.

I really enjoy playing acoustic upright bass at home, for fun. Although, I get precious little time to do it and I’m very rusty and out of practice. I’ve kept my upright bass all these years to play at home, even thought I almost never do gigs with it anymore. (I sold my electric upright).

Bass Guitars in Jazz

Do I regret my decision to stop taking gigs on acoustic upright bass? Not for a single solitary second. The upright bass is undoubtedly a beautiful instrument, but it isn’t my instrument. I’m a bass guitar player and I got to the point where I really didn’t look forward to doing gigs on upright bass. I found them to be a lot more hassle than they were worth financially.

But all this underlines the point, that as bass guitar players, we shouldn’t be aiming to take on the role of the upright bass in jazz. It’s not what jazz bands are looking for. Jazz bands that are progressive enough to want a bass guitar in the band are clearly looking for something different. Hence, the reason why I’ve played all of the harmony on bass guitars in the video apart from the bass line.

I’ve always believed that what we should strive to play is music, not just bass lines. Bass lines are an important part of music, they’re the foundation of most music. But there’s so much more music that we can also explore. And I don’t see any good reason why I shouldn’t explore all music, just because I choose to play an instrument that has the word bass in it’s name.

With that in mind, I decided to make a very short and quick demo of three basses playing a jazz tune (Solar by Miles Davis). Each bass showing a different facet of what a basses is capable of. As I’ve already described, the double bass (upright bass) is playing the bass line, the roll traditionally reserved for double bass players in jazz music.

The Acoustic Bass Guitar

The acoustic bass guitar is doing what jazz musicians term comping. Comping is basically when you use chord voicings to fill out the harmony. It’s a roll traditionally taken by piano or guitar. I’ve featured my acoustic bass guitar in a couple of recent posts. I’ve talked about how I use it as a harmonic accompanying instrument. So, rather than repeating myself, I’ll just leave these links for you to explore.

The Fretless Electric Bass

In the video the fretless electric bass is taking the rolls of melody and soloist. I suppose you could see this roll as being traditionally taken by vocalists and horn players. But, there’s actually quite a rich history of melodic bass playing in jazz. So it’s actually not that unusual to hear a bass take this role. In jazz usually everyone in the group gets a solo eventually!

Learn a Jazz Lick on Fretless Bass – Bass Practice Diary 25

Video

Learn a Jazz Lick on Fretless Bass – Bass Practice Diary – 9th October 2018

The best way to use “licks” in jazz is a subject that divides opinion amongst musicians. I’ve written a melodic jazz lick in the key of F major over a II-V-I chord progression. In this post I’ll explain the lick and also share some of my thoughts on the use of licks in jazz.

What is a Jazz Lick?

In this context, a jazz lick is a melodic phrase, like a musical sentence.  It’s a small fragment of melody that can comprise part of a longer jazz solo.

The debate amongst musicians tends to centre around whether or not it’s appropriate to use pre-learned licks as part of improvised jazz solos.  It’s something that a lot of musicians do, including really good musicians, and the argument in favour of using licks is as follows. By learning licks, you are effectively learning jazz vocabulary. And the more jazz vocabulary you learn, the greater your range will be as an improviser.

This is why I practice jazz licks or phrases. Sometimes I work out my own ones, as I’ve done in this video and at other times I play licks written by other musicians, as I have in this video.

Personally, I don’t like to use pre-prepared licks when I’m performing or playing with a band. Improvising is the thing I love to do most in music. And I like to not know for sure where the music will go. Sometimes the music can suffer as a result of this approach, and if you’re looking for more consistency in your soloing, then learning licks is a good place to start. But, I wouldn’t choose to sacrifice the process of improving by using pre-learned licks. I’ve tried it and I just don’t enjoy it. To me it feels like trying to introduce a pre prepared sentence into a conversation. It might be a great sentence, but there’s every chance it won’t make sense depending on where the conversation goes.

However, using licks is something that probably all improvisers do either consciously or unconsciously. We all fall into patterns of playing, often without realising it. I’m fairly certain that even musicians who are very against the idea of using licks, often unknowingly fall back on melodic phrases that they’ve played many times before.

Fretless Bass Jazz Lick

If you follow my Bass Practice Diary you’ll know that I like to play jazz melodies on fretless bass. So, when I do this kind of practice, I’ll always use my fretless. Having said that, the lick will also work on a fretted bass.

Jazz Lick Ex 1
II – V – I Jazz Lick for Bass Guitar

I’ve TAB’d it for 4 string bass so everyone can play it. I sold my 4 string fretless bass after I got the 6 string Warwick Thumb SC in the video. That’s the only reason that I’m playing a 6 string bass in the video.

The lick is meant to be played over a II – V – I chord progression in the key of F major. Gm7 – C7 – Fmaj7. The II – V – I chord progression is the most common chord sequence in jazz. I won’t go into the theory of it because there are so many articles in existence about II – V – I’s, like this one. I’ll just explain what I’m playing on each chord.

Inside and Outside Notes

I think the reason that jazz musicians love to play over II – V – I chord progressions is because the V chord affords a great opportunity to use outside notes. Whereas the II and the I chord tend to favour the use of inside notes. So, you can create a feeling of starting inside the harmony and then moving outside on the V before coming back in on the I. This is a very jazz approach. The feeling of taking the harmony out and then bringing it back in, immediately sounds like jazz. And it’s that sound that I’ve tried to demonstrate with my jazz lick.

If you want to learn more about inside and outside notes and how to use them then check out this video.

Here’s what I’ve played on the II chord Gm7.

Jazz Lick Ex 2
II chord Gm7

As you can see, all of the notes are in the key of F major, creating an inside sound. Which is fine because we’re about to step outside of the harmony on the V chord.

There are several chromatic alterations in this bar. Playing a b9 on beat one is a very strong statement that I’m taking the melody outside of the key signature. I love this kind of bold harmonic statement. The other chromatic alterations (outside notes) are the #9 and the b13. The final note of the bar is also an outside note, but in this case it’s functioning as a passing note rather than an altered chord extension. It’s simply a semi tone above G natural to take us to an A natural on beat one of the next bar.

How much outside harmony you choose to use is a matter of personal taste. I mentioned in the video that you could play a similar phrase on the V chord but with a natural 9th instead of the #9 and a natural 13th instead of the b13. It would go like this.

Jazz Lick Inside
Alternative Line on the V Chord

Finally, on the I chord, F major 7, the lick resolves itself onto the major 3rd A. Which is about the most inside sounding note you can use at this point.

As I’ve said, I’m not planning to use this lick again any time soon. For me, this is simply an exercise in expanding my jazz vocabulary so I can improvise lines in a similar way in future. But if you’d like to learn  it, and use it in future, I would consider it an honour that anyone chooses to play one of my lines. I hope this has been helpful!

How to Use Outside Notes In Your Basslines – Bass Practice Diary 19

Inside and Outside Notes – Start Using More Outside Notes in Your Bass Lines – Bass Practice Diary – 28th August 2018

Recently I made a video called Everything You Need to Know About Harmony on Bass Guitar. You can check it out by clicking on the link. In the video I talked about using inside and outside notes. Well I thought it was time for a practical video about how you can practice playing inside and outside notes. Here it is!

Inside and Outside Notes

The simplest way to explain inside and outside notes is that inside notes are notes that belong in the key you are playing and outside notes don’t. Hopefully you know already that I don’t believe there is any such thing as “wrong” notes. Simply because outside notes can make your basslines more interesting when they’re used in a musical way. You can use them to create tension within music, which is very hard to achieve if you only play inside notes. And the resolution of those notes onto inside notes creates a resolution of the tension.

How Can You Practice Using Outside Notes

This video is a practical guide not a theory lesson so I’m going to jump straight in to the musical examples. If you’d like to learn more of the theory then jump to my previous video which is linked in the opening paragraph.

I started with two chords, G7 and C7. And I created a bassline using only chord tones. The notes are G, B, D and F for G7 and C, E, G and Bb for C7.

Inside and Outside Notes Example 1
A Bassline Made From Chord Tones – G7 & C7

The first variation I played was to add a note one fret above or below either of the root notes. In the following example I’ve added the note Db before the C root note and Ab before the G root note. Both Db and Ab are outside notes on both G7 and C7 chords.

Outside Notes Example 2 Part 1

Outside Notes Example 3
Outside Notes One Fret Above the Root Notes

Notice that these notes always resolve onto the root note. Meaning that the next note after the outside note is always the root note. It’s that resolution that keeps the outside notes from sounding “wrong”.

Resolving Outside Notes Onto Chord Tones

You can resolve outside notes onto any chord tone. It doesn’t have to be the root. The following example starts on a Bb, which is an outside note on G7. The Bb resolves up one fret onto B natural which is a chord tone. The next outside note is Db which resolves onto the root note of the next chord C7.

Chromatic Runs

The final technique for incorporating outside notes that I looked at in the video is chromatic runs. I usually use these when leading into a chord change.

Starting three frets either above or below the root note, simply play each fret either up or down to the root. It’s a simple technique, but it sounds cool if you don’t over use it. The following bassline demonstrates the technique.
