Approach
Notes
The next step
in our discussion of chromatic approach notes is to apply them to
arpeggios. An arpeggio is simply the notes of a chord played one at
time, as opposed to all at the same time. For the purpose of
these examples we'll be looking at a Dmi7 chord/arpeggio. The formula
for any mi7 chord is root, b3rd, 5th, and b7th. We are often told
to emphasize chord tones when improvising so that we imply the song's
chord changes. As with scales, arpeggios are simply tools, and really
don't carry the music all on their own. It's the application of certain
techniques, such as this one, that really make the arpeggios musical.

Example
One shows a two octave Dmi7 arpeggio. It is important to know
the names of the notes in all chords, so that you can apply this concept
in all keys.

Example
Two shows the same arpeggio using chromatic approach notes, i.e.
each note in the arpeggio is preceded by the note a half step below.

Example
Three shows the same concept descending.
Practice this
in all keys, and on all types of chords (Ma7, Dom7 etc.). It may help
you to write them out if you are unfamiliar with chord spellings.
Combined with the chromatic approach notes we have already used on
scales, this device will really open up our playing.
