PLAYING
SCALES DIAGONALLY
I hope that the intervallic studies we have worked with so far
have inspired you to move outside of your technical ëcomfort zoneí.
Above all else, I hope that you have become more accustomed to hearing
these shapes on your own, and likewise have become better able to
recognize these sounds in the music you hear. This time around I would
like to share with you another approach to scales and modes that will
take us out of a single position and allow us to move diagonally across
the neck. This way we are able to cover a larger portion of real estate
on the fingerboard, and move to different ranges of the bass neck
instantly using a minimal amount of movement.
Playing diagonally is really just a glorified way of sub grouping
the notes from a scale into smaller portions separated by intervals.
For all of the exercises played in this lesson, we will be using an
interval of a diatonic 3rd to separate each scale fragment, and each
scale fragment will be composed of three consecutive notes from each
scale.
Written in a formula, the approach might look like this (each number
represents its respective degree of the scale):
1,2,3, [shift starting finger up a diatonic 5th] 5,6,7, [shift
starting finger up a diatonic 5th] 9,10,11, [shift starting finger
up a diatonic 5th] 13,14,15, etc...
The only condition we will place on this exercise is that each 3 note
scale fragment will begin with finger 1 (the index finger) of the
fretting hand. That forces the fretting hand to change positions after
each 3 note grouping, and this is the key to the exercise.
There are a couple of ways of looking at this. Letís take the ionian
mode, for example, applied to a 4 string bass. Using this approach,
we begin with our hand in our typical 3 note per string position (fig.1).
However, we will not be playing all the notes of the scale from this
position:
Fig.1
Notice that your index finger is lined up with the root of the scale.
Starting with this fingering, we would play the first 3 scale degrees
of the pattern, 1, 2, 3. Then, we would shift our hand to the next
string in order to place our index finger up a diatonic 5th from our
starting note (the 5th degree of the scale). We then would play three
more notes of the scale starting with the 5th, 5,6,7. Once again we
would move our starting finger up a diatonic 5th from the 5, and then
play scale degrees 9,10,11. Finally, we would move our starting finger
up another diatonic 5th from the 9 and then play scale degrees 13,14,5.
In pattern form, it would look like fig. 2:

ionian
Another way of describing this approach for ionian is as follows: Using
3 notes per string, first play the first 3 notes of Ionian. Then move
your starting position up a diatonic 5th and play the first 3 notes
of mixolydian from the 5. Then move your starting position up another
diatonic 5th and play the first 3 notes of dorian. Finally, move your
starting position up another diatonic 5th and play the first 3 notes
of aeolian. On a 4 string bass, this would be as high as you could ascend
before running out of strings.
The patterns for each of the remaining 6 major scale based modes are
outlined in figures 3-8. Practice each of these in both ascending and
descending fashion. Pay close attention to your fingerings, as they
will assist you in making clean shifts from string to string.
