The IIm7b5- V7b9- Im Progression

The IIm7b5- V7b9- Im Progression

My previous articles entitled “Guide Tones” and “The Double Chromatic Approach” introduced the concept of playing melodic ideas over chord changes that follow a system. The name of the game was to create a library of phrases that resolve from one chord to the next using guide tones. It’s very important for you to write down your ideas in a transcription book. If the phrases are not written down and committed to memory through repetition, there is a chance they will be forgotten. 

The minor version of the II V I progression consists of the chords IIm7b5, V7b9, and Im. This minor cadence is used in hundreds of Real Book tunes such as “Blue Bossa,” “Black Orpheus,” and “How Insensitive.”  This specific chord progression follows the same principles of guide tone resolution that are used with the major  II V I progression. The example below illustrates this concept.

You can also resolve guide tones from b9 degree of the V7b9 by a half step down to the 5th degree of the Im chord. 

The 5th degree of the V7b9 chord also resolves up a half step up to the flat 3rd degree of the Im chord.

If we were to analyze the scales to use over Dm7b5- G7b9- Cm, the general tonality would be Eb major (C natural minor). The G7b9 contains a B natural which is non-diatonic to the key. This chord would use the C harmonic minor scale. 

The following examples connect scales, arpeggios, and guide tones to create melodic ideas over the Dm7b5- G7b9- Cm progression.

The next example uses the double chromatic approach. The 3rd degrees of both the G7b9 and the C minor chord are being approached by two notes below in a chromatic fashion. 

Review the previous articles mentioned above in sequence before moving on to these minor progressions. Remember to write out all of your ideas and commit them to memory. Good luck!

BASS LINES: Triads & Inversions Part II

Hello bass players and bass fans! In this issue, we are going to study the triads and their inversions.

In the last lesson, we were studying triads in their fundamental position. This time, we are going to study what is known as the first inversion of the triads.

The first inversion consists of the third going on the bass in the triad, as we will see below:

C Major Triad (1st inversion)
E – G – B
C Minor Triad (1st inversion)
Eb – G – B
C Diminished Triad (1st inversion)
Eb – Gb – C
C Augmented Triad (1st inversion)
E – G# – C

See you next month for Part III… GROOVE ON!!!

Approach Notes – Part 6

Approach Notes – Part 6 

As we move into lesson six of approach notes applied to chord tones, it’s important to go back and review the previous approaches. The constant review and application of these concepts will add a layer of chromaticism to both your bass lines and solos. The approaches need to be burned into your long term/ permanent memory for them to come out in your playing. 

This first example approaches a third inversion of a G major 7th arpeggio. 

A single chromatic approach from below and a double chromatic approach from above approaches the 7th, continue to the root, 3rd, 5th, single from below and double chromatic from above to the 7th, continue to the root, 3rd, and back down. 

The next example approaches the G major arpeggio in root position.

The next example approaches the root of a G major 7th arpeggio as a single chromatic from below and a double chromatic approach from above -before continuing to the third, fifth, seventh, single chromatic from below/ double from above to the root, continue to the third, fifth, and come back down. 

The next example approaches the first inversion of G major 7th arpeggio. 

A single chromatic from below/ double from above approaches the third, continue to the fifth, seventh, root, single chromatic from below/ double from above to the third, continue up to the fifth and seventh, and back down. 

The third example approaches a second inversion of a G major arpeggio

A single chromatic from below/ double from above approaches the fifth, continue to the 7th, root, 3rd, single from above/ double from below to the 5th, continue to the 7th, root, and back down.

After studying these various approach notes, you will begin to recognize the concepts utilized in your favorite solos. Continue the journey and good luck!

Triads & Inversions Part I

Hello bass players and bass fans! In this issue, we are going to study the triads and their inversions.

It is very important for all bassists to understand and master the triads, but it is even more important to understand their different inversions.

In Part I, we are going to learn what the triad is in fundamental position.

The Formula consists of root, third and fifth.

Degrees of the Triad

Major Triad: 1 – 3 – 5
Minor Triad: 1 – b3 – 5
Diminished Triad: 1 – b3 – b5
Augmented Triad: 1 – 3 – #5

Premiere! Bass Playthrough With Foetal Juice's Bassist Lewis Bridges - From the Album, Grotesque

Premiere! Bass Playthrough With Foetal Juice’s Bassist Lewis Bridges – From the Album, Grotesque

Bassist Lewis Bridges Shares…

“Gruesome’s sparse intro marks a stark contrast from the intensity of the rest of the album.  The original intention was to keep the bass simple but colourful, however as I worked on it, the lines grew more expressive and the more striking flourishes began to emerge.  The intensity builds into a harmonic minor passage that takes us into the drop — a signature death grind cacophony.  This is where Foetal Juice thrives.  You’re getting a full-on right-hand barrage to in the face to take you into a groove-laden mulch-fest.

I owe my throbbing bass tone to the Darkglass Alpha Omega pedal borrowed from our sound engineer, Chris Fielding (ex-Conan), mixed with the clarity of the tried and true Ampeg SVT CL.

As mentioned earlier, colourful basslines are important, especially in a one-guitar band. Chucking some funny intervals and odd flourishes here and there brings life into the brutality. There’s no point sounding brutal if it’s not gonna be fucking evil too!

Recording this playthrough was hard work. This was not the fault of James Goodwin (Necronautical), who was kindly filming and is ace to work with, but because in true Foetal fashion, we had stinking hangovers — and that jam room was hot!”

Bass Lines: The Circle

Bass Lines: The Circle…

Hello bass players and fans of bass! This month we’re going to study “The Circle.”

The Circle of Fourths can also be called “The Circle of Fifths or just The Circle.

Practicing the scales, chords, and ideas in general via the circle has been a common practice routine for jazz musicians and highly recommended.

It is a disciplined way of working through all twelve keys.

Plus, many bass root movements to jazz and pop songs move through sections of the circle.

Fig. 1 – “The Circle”

See you next month for more full bass attack!
