Chromatic Jazz Lines – Bass Practice Diary 7

Chromatic Jazz Lines – Bass Practice Diary – 5th June 2018

This week I’m working on chromatic jazz lines and exercises. I’m using a book called 240 Chromatic Exercises + 1165 Jazz Lines. I’m using the edition for bass clef instruments. 

About the Book

The title of the book tells you exactly what to expect. There’s very little text in the book, only in the introduction. So, the main part of the book contains page after page of chromatic jazz lines and exercises all written out in the bass clef. There isn’t any bass TAB so it’s a book for readers or for anyone wanting to work on bass clef sight reading. There’s a lot of information and it would take a really long time to play through the entire book. 

Olegario Diaz

It was written by the jazz pianist Olegario Diaz. If you’re not familiar with him I would highly recommend checking out some of his albums such as The Skyline Session, Basquiat by Night/Day and Aleph in Chromatic. They’re all available on Spotify and they feature some heavy weights of modern jazz such as Randy Brecker, Bill Stewart, Jeff Tain Watts, James Genus, Nate Smith, Bob Franceschini and Alex Sipiagin.

The Exercises

As mentioned previously, the book has lots of musical examples and exercises and not very much in the way of text and description. What you get is a chord symbol with alterations, such as C-7b5+11, and a very brief description, such as, ARPEGGIOS ROOT, b3, b5,♮7. The rest you’re left to work out for yourself from the notated exercise.

At the end of the video I demonstrated five examples. I choose them more or less at random from a page I was working on in the book. The first two examples that I played were both altered scale patterns in the key of C. Then, the third one I played is probably my favourite of the five. It’s the one I referenced in the paragraph above. It involves playing five note arpeggios over a minor/major chord with a flattened fifth (minor third and a major seventh). The arpeggios start on the root, then on the minor third and then on the flattened fifth.

The fourth and fifth examples uses four note major and minor seventh arpeggios with chromatic approach notes. The fourth exercise is played over a major seventh chord, creating a lydian sound and then the fifth exercise is played over a minor seventh chord.

I’m playing all these examples on my Custom Shop  Warwick Thumb SC 6 string fretless. I prefer to use fretless for jazz and melodic playing but I do have to be careful to get the intonation right. So, check out this post if you’re interested in learning more about the instrument.
