Passing Notes

Passing notes are scale tones that pass between two chord tones by scale step. Chord tones are the root,
third, fifth, and seventh scale degrees of a scale. Scale tones are the second, fourth, and sixth scale degrees.

Composers have utilized this passing notes concept for centuries. From J.S. Bach to Charlie Parker,
Miles Davis and beyond, musicians have made extensive use of this common technique. Listen to
Bach's compositions and you'll hear passing notes. Check out the melody to "Four," a classic jazz
standard filled with passing notes, by Miles Davis.

In Example 1, you will see a two-octave CMaj7 arpeggio. In Examples 2-7, you'll find every permutation 
of the passing notes technique applied to a two-octave CMaj7 arpeggio on a 4-string bass.

These combinations are as follows:
Passing note between the root and third (C-D-E-G-B)
Passing note between the third and root (E-D-C-G-B)
Passing note between the third and fifth (C-E-F-G-B)
Passing note between the fifth and third (C-G-F-E-B)
Passing note between the fifth and seventh (C-E-G-A-B)
Passing note between the seventh and fifth (C-E-B-A-G)

Tablature has been provided to assist as a positioning reference. Depending on where you shift from
one note to the next on a 4-string bass, keep in mind that there are several other ways to play a
two-octave arpeggio, and you should definitely experiment with as many permutations as possible. For
the extended range bassist who plays a five or six-string instrument, these exercises are easier to play
because the extended range allows the examples to be played across the fingerboard without the
necessary shifting required to play these exercises on a 4-string bass. On an extended range bass, this
passing notes concept can be applied to three-octave arpeggios. Every bassist can also take these
techniques and apply them to all the inversions of a Major 7th arpeggio (1st inversion: E-G-B-C, 2nd
inversion: G-B-C-E, and 3rd inversion: B-C-E-G).

After you practice this passing notes technique on all of the two-octave Major 7th arpeggios(CMaj7,
GMaj7,DMaj7, AMaj7, EMaj7, etc.), you'll want to apply this concept to the following chord types:
Cm7
C7
Cm7b5
Cdim7
CmMaj7
C7sus4
CMaj7#5
CMaj7b5
C7#5
C7b5

If you would like to associate scales with each chord type, here is a list of the most common chord types
with their related scales:

Maj7: Ionian, Lydian, or Major Pentatonic
m7: Dorian, Minor Pentatonic, Blues Scale, Aeolian, or Phrygian
7: Mixolydian, Lydian b7, Minor Pentatonic, Blues Scale, or Half-Step/Whole-Step Symmetrical Diminished
m7b5: Locrian #2 or Locrian
dim7: Whole-Step/Half-Step Symmetrical Diminished
mMaj7: Melodic Minor (Jazz Minor or Jazz Minor #4)
7sus4: Mixolydian
Maj7#5: Lydian Augmented
Maj7b5: Lydian Augmented or Lydian
7#5: Whole Tone or Altered Dominant (Super Locrian)
7b5: Whole Tone, Altered Dominant, Lydian b7, or Half-Step/Whole-Step Symmetrical Diminished

Keep in mind that this is by no means a comprehensive list of all the scales musicians will practice with
these chord types but rather a list including some of the most favored scales played by musicians over
these chord changes.

Be sure to apply all the correct passing notes to each chord type. For example, if you are playing Lydian
over a Maj7 chord, the passing note will be a #4 as compared to the perfect 4th of Ionian. If you are
practicing Lydian b7 over dominant 7 chords, the passing note will be a #4 in comparison to the perfect
4th of Mixolydian. The symmetrical diminished scale will have a #4 and double passing notes
(C-Db-D#-E) between the root and third as compared to Mixolydian. Basically speaking, if you
associate multiple scales with a chord type, there may be several passing note combinations for that
particular chord type.

Examples 1-7 are basic exercises to help you develop the passing notes concept over the most utilized
chord types. In Example 8, I have included a phrase composed of passing notes. This is the type of line
that you would hear in a more musically applicable context such as in a solo or melody. Take the passing
notes concept and experiment with composing your own lines using passing notes. With the virtually
limitless number of phrasing permutations, you are only limited by your imagination.

Always remember to practice every example over every chord type and transpose each chord type to
every key across the entire range of the fingerboard. To make this amount of practice material more
manageable, I would recommend practicing one chord type per day in every key center. For example, on
the first day apply this passing notes technique to the major 7 chord type. On the following day, practice
applying passing notes over minor 7 chord types and so forth. Within two weeks, you will have applied
the passing notes concept to all the necessary chord changes.

 

 Disco Octave

This fun, upbeat tune has a bass line playing octaves while walking over two chords.

Technique Tips: The bass pattern starts on the root of the chord being played, jumps down 4 frets then walks chromatically(1 fret at a time) back up to the root. Try playing this with either the finger-style approach or using the slap-and-pop technique.Keep your focus on emphasizing the downbeat.

Theory Thoughts: This tune uses “dominant seven” chords. This means the 7th scale degree is flat (lowered a half-step).

So, the E7 (meaning dominant seven) has a D natural as the seventh scale degree (instead of D#). This causes the distance or interval of a tri-tone between the 3rd and 7th scale degrees (in E, these scale degrees would be G# and D) which adds musical tension to the sound of the chords.

Main Objectives: Creating a solid “in the pocket” feel, locked in with the drummer, is most important. Developing a left

hand technique that becomes second nature is necessary to play this for an extended period of time. Notice how you can cut each note off early (also called staccato) to create more of a “punchy” feeling.
