We've talked a lot about the chord scales,
but there's such a thing as key scales.
And it's actually gonna be one of the
techniques that's going to make our life
so much easier.
Blue Bossa has three phrases.
The first phrase is C minor to F minor.
And then we have a 2-5-1 in C minor for
the second phase.
All of that, the first eight bars,
are in C minor.
You could play C Aeolian scales
over all eight of those bars.
[MUSIC]
Then, the third phrase
is a 2-5-1 in D flat major.
So we're modulating up a half step,
and playing the major scale.
[MUSIC]
Then the final phrase is,
again, a 2-5-1 in C minor.
So we can practice just these
key scales as the batches
of notes we can choose from for
our improvisation.
Let me show you what running key
scales would look like on Blue Bossa.
Instead of just playing one octave up and
down,
I'm gonna just keep going continuously
all across first position.
And I'm not gonna change direction for
every chord.
I'm gonna keep running the key
scale all the way until bar 13,
when I'll instantly
change to D flat major.
And do that scale continuously for
four bars, and then back to C minor.
I'll show you what I mean.
[MUSIC]
All C minor.
[MUSIC]
Now I'm gonna switch to D flat.
[MUSIC]
Back to C.
[MUSIC]
I'll do it one more time for
you without talking.
See if you can hear the D flat.
[MUSIC]
You
can actually
improvise up and
down as much
as you want.
You don't have to keep it
all regimented too much.
This is really about just
establishing these root keys, and
knowing when to change
your root key scale.
And in Blue Bossa,
that's gonna happen just for
those four bars that
are gonna be in D flat major.
