[Harp-L] vertical blues

[Music Cal <macaroni9999@xxxxxxxxx>]

I have a question about vertical vs linear improvisation as applied to jazz
blues. If you don't know what is meant by these terms then allow me to
briefly define them here:

(1) Linear improvisation: Lines built upon the tension and resolution
created by the movement of single notes. These lines could be drawn from
modes or from the entire chromatics scale but they tend to be heard as a
sequence of individual notes.

(2) Vertical improvisation: Lines built upon the tension and resolution
created by the movement of arpeggios. Although the notes are played one at
a time (unless you have a chord-playing instrument) the musical movement
tends to be heard in terms of the movement of arpeggios rather than in
terms of single notes. The arpeggios may include the arpeggio of the chord
that accompanies the improvisation or it may be other arpeggios that lend
diatonic or chromatic movement of an entire arpeggio rather than a single
note.

OK so there is my definition of the terms. If yours is different then I
hope you will share it with me. Art is perspective!

OK but I have not gotten to my question yet. Onward.

At this point in my musical journey when I internally hear jazz blues
improvisation I tend to hear bluesy linear lines. I hear vertical lines but
they are not bluesy. So here, finally, is my question (whew!): Do you know
of some vertical lines or approaches to creating vertical lines that lend a
particularly bluesy feel to improvisation?
