A Bit More Complicated
This lesson looks at chord sequences that don't fit into
a single key.
The sequence I am going to use to illustrate this is :-
VERSE
| Ebmaj7 / / / | ~ | ~ | ~ |
| D7 / / / | ~ | ~ | ~ |
| Dbmaj7 / / / | ~ | ~ | ~ |
| Cm / / / | ~ | ~ | ~ |
| Bbm / / / | ~ | Ab / / / | ~ |
| Bbm / / / | ~ | Ab / / / | ~ |
CHORUS
||: Ebmaj7/G / / / | ~ | Abmaj7/C / / / | ~ |
| Ebmaj7/G / / / | ~ | Abmaj7/C / / / | ~ |
| Ebmaj7/G / / / | ~ :|| - This ten bar section repeats once.
Phew! 44 bars of "What key is this?"
Listen to the sound files to hear the sequence: - The first one is just the
chords for you to improvise over.
The second one is the same sequence with steel-string lead and bass - for illustration
purposes.
I recommend working on the sequence solely as chords for a bit before going
on to the lead improvisation - this helps to establish the sequence in your
mind when soloing.
I have put a diagram (below) of Ebmaj7/G in case you are not familiar with this
chord - use the same shape for Abmaj7/C.
Notice that the first four chords are descending chromatically with
no altered bass notes - this means that they can't all be in the same key.
If you have got to grips with the key structure outlined in lesson 7 and
can transpose you might be able to spot that the first two chords
( Ebmaj7 & D7 ) fit into a key structure of G minor.
The remaining chords in the verse section all fit into a key structure
based on F minor.
The chorus section uses chords from a C minor
structure.
The fact that wer'e not in a minor key doesn't really matter because the
key structures, as outlined above, give us the information to know what
scales to use on different parts of the tune.
The scales I would use are : -
G natural minor or possibly G harmonic minor
for the first chord.
G harmonic minor for the second chord.
F natural minor for the rest of the verse.
C natural minor for the chorus.
I would also look for strong notes to hang about on as the sequence goes
through.
All this may seem fiendishly complicated at first but, like most concepts
in music, the more you get into it the easier it gets!
The first soundfile will loop for you to practice your scales and improvisation
skills over the top.
This should give you an excellent workout for everything you've learned
so far.
