I do use it to run all these wonderful reharmonizations we discuss.
While the band in the box doesn't groove as much as I'd like, it sure
helps one as an improv tool, as well as giving one a band to play along
with as a rythmn section player.
I have always believed that when I play chromatic notes "passing tones"
in my walking lines that I am effectively employing chord
substitutions. I have played with this concept using some of the
reharmonizations we have discussed. I play a line (using chord tones
mostly) based on the reharmonized progression, but play it over the
original progression using Band-in-a-Box. It seems to confirm my
original belief (the chord tones of the reharmonized chords, against
the original chords, would be passing tones in the context of the
original chords). Does this seem to make sense?
