Create Chromatic Jazz Lines by Using Passing Notes – Bass Practice Diary – 19th January 2021

When you improvise a jazz line, you can put a chromatic passing note anywhere, right? That’s true up to a point. But your lines will be significantly improved if you think about where you place them. Chromatic passing notes can be used to connect scale notes and chord notes. In this video I’m looking mostly at scales, but you still need to think about where you play the chord tones. Otherwise your chromatic jazz lines can sound like you’re just playing a chromatic scale.

Chromatic Passing Notes

The idea behind chromatic passing notes is very simple. You simply move between two notes chromatically (in half steps). Major scales consist of five whole step intervals (whole tones) and two half step intervals (semitones). That means that there are five places in a major scale (or any of it’s modes) where you could place a chromatic passing note. Between any of the five whole tone intervals.

If you place a chromatic passing note in all five places, you have a chromatic scale. We don’t want our lines to sound like we’re playing a chromatic scale. We want them to sound like they belong with the harmony of the music. So, to make a chromatic jazz line sound like it fits the harmony, you need to think about what the chords are. And where are the chord tones in your line.

My Chromatic Jazz Line

Chromatic Jazz Line on a II V I in D Major

This is the line I featured in the video. I’ve used a chromatic passing note on the V chord A7. I’m thinking of the whole line as being in D major, so I’m using the notes of the D major scale. I’m also thinking about the chord tones for each chord. So, on the A7 I’m thinking about A, C#, E & G. The one chromatic passing note that I’ve included on the second bar is placed between the root note, A and the 7th, G. I’ve done that to ensure that both notes land on the beats, while the chromatic passing note (G#) lands on the off-beat.

The rest of the notes in that bar are taken from the D major scale (or A mixolydian mode). The addition of that one passing note between the root and 7th ensures that a chord note lands on every beat. The notes on the off-beats act as passing notes (either scale notes or that one chromatic note). This basically gives us what is known as a bebop scale.

Bebop Scales and Beyond

A bebop scale on a dominant 7th chord is just the notes of the mixolydian mode with the addition of that one chromatic passing note between the root and 7th. It’s a useful scale because if you start by playing a chord tone on beat one, as I did. You can play the scale either descending or ascending. If you play 8th notes starting on beat one, you will hit a chord tone on every beat.

That’s not the only bebop scale. There is one for major chords as well that involves adding a chromatic passing note between the fifth and sixth notes of a major scale. There are three other bebop scales which I might cover in a future video. The dominant 7th version that I’ve used here is the one I use most often.

But what if you want to go beyond bebop scales and play more than one chromatic passing note in a line? I’ve given one example in the video of playing a chromatic line that goes from 3rd down to 7th chromatically.

It’s essentially just a sequence from the chromatic scale. But it works as a jazz line because I’ve planned where the chord tones land. The 3rd lands on beat one, the 9th on beat two. The 9th is a chord extension, but it can be treated as a chord tone for the purposes of making jazz lines. Then the root note is on beat three and the 7th on beat four. When you listen to it played against an A7 chord, you can hear the sound of the chord coming from this chromatic line.

Tapping Jazz Lines – Can You Play Jazz Solos With Two-Hand Tapping? – Bass Practice Diary – 8th December 2020

I’ve witnessed a couple of musicians in the UK playing improvised jazz solos with a two-hand tapping technique. However, I’ve never heard anyone talk about this idea. It seems to me that there is an obvious advantage to using two-hand tapping to play jazz lines. The advantage is that you can easily make big interval jumps in your lines. That is quite hard to do with a conventional playing technique. For a long time, I’ve wanted to explore the idea myself. So, when one of my advanced bass students brought up the subject of tapping in a lesson, I jumped at the opportunity to work through some ideas with him.

How I arranged the lines

We started by coming up with a jazz line on a II-V-I in Bb. This is a very typical exercise for learning to play jazz. The line we came up with was this.

We then tried to rearrange the line by moving some of the notes up one octave to be tapped with the right-hand. The remaining notes would be hammered-on by the left hand. This is the finished line.

We went through the same process again and came up with another line, which goes like this.

If you’d like to learn more about my two-hand tapping techniques, then check out my previous videos on the subject. This video looks at the basic two-hand tapping technique of hammering and pulling notes with both hands. This video looks at arranging chords and chord progressions with two-hand tapping.

This idea of using two-hand tapping to make jazz lines is still very new for me. I hope I will revisit this subject in the future when I’ve had more time to work on it. At the moment, I’m still at the very early stage of working out lines and practicing them. I hope that as time goes by, I will develop the ability to improvise lines in this way.

How to Make a Major Scale Sound Like Jazz – Bass Practice Diary 134

How to Make a Major Scale Sound Like Jazz – Bass Practice Diary – 17th November 2020

If you study harmony, you begin to realise just how important the major scale is. Diatonic harmony in its entirety realties to the intervalic relationships of the major scale (also sometimes called the diatonic scale). So, it’s hardly surprising that a major scale is a popular choice for improvisation as well. But, how do you make a major scale sound like jazz?

Why use major scales in jazz improvisation?

I think that a lot of musicians learn to analyse diatonic chord progressions in jazz standards. They know the right key to play at every point in the progression. Each key is defined by the notes of the parent scale, which in the case of major keys, is a major scale. So, you can break a lot of jazz tunes down to playing different major scales at different points in the chord progression. But the problem is, that major scales on their own don’t sound very much like jazz. So, how do you use the major scale to make jazz lines?

I’ve noticed that a lot of people learning to improvise are looking for a scale or scales that will make them sound like jazz. I don’t think it works like that. I think there are a lot of different approaches to improvising in a jazz style. Today, I’m looking at two key concepts. One is approach notes, the other is outside notes. The concept of outside notes is simple to understand. There are seven notes in any key (the notes of the major scale) and there are twelve notes in the octave (the chromatic scale). Outside notes are the five other notes that are not in the major scale. If you want your lines to sound like jazz lines, you need to come up with some creative ways to use them.

A simple and great way to begin to incorporate some outside notes into a major scale, is with the use of chromatic approach notes. A chromatic approach note can be as simple as picking a target note from the parent scale, and playing a semi-tone (one fret) below or above that note before you play it. Of course, not all of these chromatic approach notes will be outside notes. If your target note is the major 7th, and you play a chromatic approach note above that note, you’re playing the root note. But some (most) of your chromatic approach notes will be outside notes. And that’s enough to bring a jazz flavour to your lines.

Play a major scale with chromatic approach notes

This is an exercise that I featured in the video.

Major Scale Jazz Exercise with Chromatic Approach Notes

I’m playing a C major scale in ascending thirds (root, 3rd, 2nd, 4th, 3rd, 5th etc). Each third interval is two notes. I’m then adding a chromatic approach note before and below the first, lower note. So, C, E (Root, 3rd) becomes B, C, E, a three note grouping. D, F (2nd, 4th) becomes C#, D, F.

It sounds good, but it sounds like an exercise. I want to make it sound less like an exercise and more like an improvised jazz line. Try mixing up the exercise by varying the chromatic approach notes either above or below the target notes. You can also vary whether you play your thirds ascending or descending. When you play a descending third you can play the approach note before the higher of the two notes.

Here’s an example that I played in the video.
