The Bass Clef Real Book – Bass Practice Diary 62

Using the Bass Clef Real Book – Melody and Bass – Bass Practice Diary – 25th June 2019

Jazz musicians love to practice with Real Books. And most Real Books are now available in bass clef editions. I have several different editions of bass clef Real Books, such as this one. And in this video I’m demonstrating a system of practicing with the Bass Clef Real Book that combines playing melodies with bass notes. I’ve seen guitarists using this system but it’s not often used by bass players.

What are Real Books?

Real Books are big books filled with hundreds of jazz tunes and standards. The arrangements are mostly written very simply as just a single melody line with chord symbols written above. Some of the tunes have little bits of additional arrangement written in, such as a bass line or harmony. But mostly they just distill each tune down to the simplest structure of melody and chords. The concept was created so that jazz musicians could use a standardised melody and chord progression for each tune when playing them at jam sessions.

How can you use Real Books when you practice?

There are a few different ways that you can use Real Books when you practice. The obvious one is for learning the melody and chords of famous jazz tunes. And they’re also good for sight reading practice. There are a wide range of jazz tunes in most Real Books, everything from slow simple ones to fast complicated Bebop lines. So there should be something to practice, no matter what your reading level is. You could also practice improvising on the tunes with the addition of play along backing tracks.

But this week I’ve been trying something different with my Real Books. Instead of just reading the melodies alone, I’ve been trying to include the root notes of the chords, to make a simple solo arrangement of each tune. This is a concept that I’ve heard jazz guitarists like Julian Lage and Martin Taylor talk about.

The idea is that it helps you to learn the tunes by boiling them down to the fundamentals of melody and bass. So rather than thinking about chord changes (which jazz musicians do a lot) you are thinking more about how does the melody interact with the simple bass line root movement.

I’ve only recently started doing this, but here is a transcription of one of my early attempts. The tune is All of You by Cole Porter.

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.
