String Skipping Arpeggios – Another 6-String Bass Exercise – Bass Practice Diary – 18th May 2021
This is another 6-string bass exercise featuring string skipping. The last one involved playing scales and skipping strings after every three notes. This one is a bit more difficult. It involves playing arpeggios and string skipping on every note. I first came across this exercise years ago when I saw it featured on an instructional video by the great guitarist Frank Gambale. It’s a tricky exercise to play on guitar or bass, but it sounds great. When I was thinking of ways to take my string skipping on bass to another level, I remembered this exercise and I set about trying to adapt it onto 6-string bass.
I’ve played the exercise in the key of A minor, which is the same key Frank Gambale plays it in. The exercise uses notes from the A harmonic minor scale arranged into three arpeggios. Chord I, A minor, chord IV, D minor and chord V, E. The A minor arpeggio is played as a triad using just the notes A, C and E. But the IV chord includes the note B on a D minor chord, which makes it Dm6. The V chord is really E7, but the exercise only features the notes of the major triad, E, G# & B. It’s played like this.
Extended Arpeggios on 6-String Bass with Bass TAB – Bass Practice Diary – 3rd March 2020
Extended arpeggios are a great way to practice harmony on 6-string bass. All chords and arpeggios derive from scales, and an extended arpeggio is a brilliant way to present the sound of a scale or mode, without it sounding like you’re playing a scale. For that reason, they work brilliantly in solos.
How to work out an extended arpeggio
The extended arpeggio ideas that I’m using in the video are actually much easier to work out than they sound. You can work them out by taking a scale, in this case the C major scale, because I’m using a II-V-I chord progression in C major. And when you have your scale, you can play the extended arpeggios using alternate notes in the scale. There are seven notes in most major and minor scales, so when you’ve played seven consecutive alternate notes, you’ve played every note from the scale as an arpeggio.
Here’s how it works. The notes of a C major scale are C, D, E, F, G, A & B. Imagine you’re playing a two octave scale so each note happens twice, giving you fourteen notes across the two octaves. Take the 1st, 3rd, 5th, 7th, 9th, 11th and 13th notes of that two octave scale. These are notes C, E, G, B, D, F & A, which is your C major extended arpeggio.
NB. Jazz musicians often play a #11, in this case F# on a major 7th extended arpeggio.
Next you could take the 2nd, 4th, 6th, 8th, 10th, 12th & 14th notes of the two octave scale. This will give you a D minor 7th extended arpeggio. This is the arpeggio I featured in the video.
Arpeggios with a chord substitution
Here is the full example that I featured in the video.
I’ve explained how I created the extended arpeggios for the Dm7 and Cmaj7 chords. So, how did I create the arpeggio that I played on the G7 chord? I could have done it using all the notes of a C major scale. But I felt that would sound boring if all three arpeggios used the same set of notes.
Instead, I used the notes of a common chord substitution, the tritone substitution. It’s a harmonic device that jazz musicians love to use on dominant 7th chords. In this case, for the G7 chord, I’ve used an arpeggio for a chord with a root note that is three tones (a tritone) away from G, which is Db7. It works because the 3rd of the G chord, B, is the 7th of the Db chord. And the 3rd of the Db chord, F, is the 7th of the G chord.
So, I harmonised my extended Db7 arpeggio using notes from Gb major. Db7 is chord five in the key of Gb major. This creates a lot of dissonances, some notes in Gb major work in the key of C major, but also some sound quite dissonant. But that’s the point, jazz musicians love to create tension by using dissonances on a V chord before resolving them on the I chord.
Learn a Jazz Bass Lick by Jeff Andrews – Bass Practice Diary – 19th March 2019
I heard the news a couple of days ago that Jeff Andrews had passed away. He really deserves to be remembered as one of the great jazz electric bass players. I know him best from his work with Mike Stern. He played on albums such as Time in Place and Between the Lines which have been among my favourites for a long time. As well as his work with Mike Stern, he’s also played with jazz and fusion greats like Michael Brecker, Bob Berg, Vital Information and Steps Ahead.
After hearing the news, I immediately started listening to some of those albums again. And I also found a really cool compilation of his solos on Youtube. It really struck me what a great musician and improviser Jeff Andrews is. And predictably I started trying to work out what he was playing. What I found was a goldmine of incredible jazz lines improvised on electric bass.
Using Inside and Outside Lines
What struck me about his style was his brilliant use of inside and outside lines. It’s a commonly used technique of many jazz improvisers. Incorporating lines that are both inside the harmony and outside the harmony as a way of creating tension and resolution. Jeff Andrews is an absolute master of this. He improvises lines at high speed that outline the harmony, but then take you way outside the harmony before bringing you back in for the resolution.
Jazz Blues Bass Lick
The lines he creates are so cool, and I could have picked any one of his lines as a demonstration. But I choose this one which is from a Mike Stern tune called Bait Tone Blues.
This line takes place over the last four bars of blues in F. And it starts by clearly outlining a ii – v in the key of F. But then follows a sequence which starts on a B natural and ends with a sort of chromatic run featuring the notes A, Bb, Ab, E and G. That’s an uncomfortable sounding sequence of notes when you play it over a standard blues turnaround in the key of F. But then having played that outside sequence, he immediately brings it back inside the harmony by outlining a C major triad at the end. With the C7 functioning as the V chord in the last bar of the blues.
It’s really hard to analyse some of these outside lines other than to say that when you play the lick through, it just sounds really cool. And it shows that Jeff Andrews had incredible musical instincts as an improviser. He had the ability to throw in outside passages and make them sound like they fit with the inside harmony. He will be missed.
