How I Approach Improvising on Dominant 7th Chords – Bass Practice Diary 163

How I Approach Improvising on Dominant 7th Chords – Bass Practice Diary – 22nd June 2021

I’ve mentioned many times in previous videos that jazz musicians love dominant chords. They love them because there’s so many different ways you can play on them. Depending on the context, you can get away with playing any note on a dominant chord. But it doesn’t help you learn how to improvise if you think “play anything”. It helps if you think about strategies for improvisation. I think everyone who improvises has at least some kind of strategy. And a more experienced improviser probably has many strategies to draw upon. So when you’re practicing improvisation, don’t just pick your favourite strategy. Practice as many strategies as you can think of. And then you never know what you might discover.

Strategies for Improvising on Dominant 7th Chords

In this video I’ve tried to include many of the common strategies for playing on dominant 7th chords. And this is by no means an exhaustive list. Some of these ideas I’ve featured in videos before. Click here to find my video about chromatic approach notes. This video is about the altered scale. And this one is about combining diminished and blues scale sounds.

To me, every scale is a sound. Or it creates a particular sound against a specific chord. So, when I’m improvising, I’m thinking about sounds, not scales. But, having said that, all of these scales form those sounds, so that’s why we think about scales when we study improvisation strategies. The important thing to remember, is that when you’re learning any of these scales. You are not just learning a fingering or a pattern on the fretboard. You are trying to learn the sound that it creates against a dominant chord. Here are the scales.

The Modes of the Melodic Minor Scale – Bass Practice Diary 54

The Modes of the Melodic Minor Scale – Bass Practice Diary – 30th April 2019

Recently I did a video about the altered scale, which is one of seven modes that come from the melodic minor scale. You can find it here. That got me thinking about the other modes of the melodic minor scale. There are a few that I use quite a lot, but there are others that I almost never use. So this week I set myself the task of practicing all of them, and thinking about what harmonic context I can use them in.

If you’ve seen my altered scale video, you’ll already know that melodic minor scale is only one note different from a major scale. If you take out the major 3rd from a major scale and replace it with a minor 3rd, then you have a melodic minor scale.

This small alteration creates the potential for seven modes, that are each different and distinct from the seven major scale modes. (Ionian, dorian, phrygian, lydian, mixolydian, aeolian and locrian). Modes are extracted from scales by changing the root note to a different degree of the scale. For example, if you play the notes of a C major scale but change the root note to D, then you have a dorian mode.

What are the melodic minor modes?

These are the seven modes of the melodic minor scale. Each has been written out in one octave and I’ve written the implied chord symbol above each mode. I’ve chosen to use D melodic minor for this exercise.

The first mode is the melodic minor scale itself. I use the melodic minor to play on minor 6th chords and it can also be used on minor/major chords (meaning minor 3rd with a major 7th.

The second mode is like a dorian mode with a flattened 2nd. It implies a minor 7th chord. But the flattened 2nd is a strange note to play on a minor 7th chord. Hence, this is one of the modes that isn’t commonly used.

The third mode is like a lydian scale with a raised 5th. The implied harmony is a major 7th chord with a #5. I don’t currently use this scale a lot. But I’ll try and use it more in future, because it sounds cool.

The fourth mode is usually called lydian dominant because it has a raised 4th, like the lydian mode. But it also has a dominant (flattened) 7th. It’s a scale that I like to use on dominant 7th chords. It’s essentially a mixolydian scale with a raised 4th. Which makes it sound more interesting than a mixolydian scale when played on an un-altered dominant 7th chord.

The fifth mode is basically a mixolydian scale with a flattened 6th. I don’t use it very much but you could use it on a dominant 7th chord with a b13.

The sixth mode works well on half diminished chords (m7b5). It has a minor 3rd and 7th and a flattened fifth. But unlike the locrian scale, it has a natural 9th rather than a flattened 9th.

The seventh mode is the altered scale, which I’ve already covered in my previous video. It’s an extremely useful scale for playing on altered dominant chords.
