Use Intervals of a 4th To Create a Modern Jazz Sound – Bass Practice Diary 43

February 12, 2019 jccoxjazzbass 1 Comment

Playing lines in 4th intervals is a very popular sound modern jazz. It’s a very distinctive sound. And once you’ve incorporated it into your playing, you’ll start to recognise when you hear other musicians using it. This video features an exercise that I’ve written to help you incorporate this sound in your playing.

If you’re not sure what I mean by an interval of a 4th then check out my video guide to playing intervals on the bass.

How to Play 4ths on Bass Guitar

There are two obvious ways to play 4ths on bass guitar. I believe that if you’re going to be able to come up with basslines in 4ths, then you need to practice and use both ways.

The first way is the easy way. You go from any fretted note to the same fret on an adjacent string. The bass is tuned in 4ths. So, as long as you stick to the same fret, you’ll be playing a 4th. This is very simple and you can apply this to playing scales and harmonies. Here is a G major scale played in intervals of a 4th.

This way of playing 4ths is so simple, that it can lead to some bass players ignoring the slightly more complicated way of playing 4ths. Which is by shifting position up five frets on a single string. Like this.

I think that this element of shifting position, is essential if you’re going to create musical lines in 4ths. If you only use the first, easier technique, then you’ll very quickly find that you’re stuck in one position on the bass neck. And as a result, it will massively limit your ability to come up with musical lines.

The 4ths Exercise

So I’ve written this exercise, which is designed to help you practice playing 4ths in both ways.

I’ve written it in the key of A major. But, if you want to master it, please practice it in any and every key. The concept is simple. It starts with a position shift from the A on the 5th fret of the E string to the D on the 10th fret. Then you play a 4th interval from the B on the 7th fret to the E on the 7th fret of the A string.

So it immediately uses both ways of playing 4ths. Then it repeats the same pattern all the way up the neck until you can’t go any further. And then you play everything the same way in reverse.

Once you’ve got used to playing lines in 4ths, start to listen to listen out for the sound of 4ths in other musicians lines. Listen to players like Evan Marien, he’s a brilliant bass player that loves the sound of 4ths in his basslines.

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 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.
