Modal Basis for “Cocaine Decisions” – Very Rough Interpretation
This piece can be cut into four main modal/harmonic movements :
(1a) Modal movement in the fifth mode of the F Melodic Minor scale
(1b) Varition movement in the fifth mode of the Gb Melodic Minor
scale (half step up)
(2) Modal movement in the fourth mode of A Major, ie. in D lydian
(3) Dominant turn-around in the fifth mode of C Major, ie. G7
Some Background on The Fifth Mode of Melodic Minor
(Parent Scale) F melodic minor scale : F G Ab Bb C D E
Triads of the F melodic minor scale : Fmin Gmin Ab+ Bbmaj Cmaj Ddim Edim
… this gives the scale three sets of similar triads spaced a
whole tone apart:
F- and G- … Bb and C … Ddim Edim
7th Chords of the F melodic minor scale: F-maj7 G-7 Abmaj7+5 Bb7 C7 D-7b5 E-7b5
… this gives two parallel structures a whole tone apart:
Bb7 and C7 – two dominant chords (!) and D-7b5 and E-7b5 – two half-diminished
chords, related to the dominant chords which, superimposed, become Bb9 and C9
… and then there’s the super weirdo chord Abmaj7+5 … notice the front end
of the scale almost sounds like the dorian mode except for the maj7 on the F-
chord …
Movements
(1a) modal movement in the fifth mode of the F Melodic Minor scale
The tune starts out with a simple C major triad sound, bass stomping away –
keys mixed way in the back – harmonica playing minor blues licks in C (!) … so
from a general harmonix viewpoint there’s this blues mixing going on throughout
the tune on top of modal permutations … there’s three different types of C tonalities
going on in close viscinity – that’s some Harmonic Mixing in action !
… starts on a lead-in four bars long:
INTRO: || C | C | C | C ||
The first harmonic structure goes something like this …
|| Ddim/C | Ddim/C | C | C || x3
… using the following basic voicings for Ddim/C, C
—————————————————————————-
—–6——-5————————————————————–
—–7——-5————————————————————–
—–6——-5————————————————————–
—————————————————————————-
—-10——10————————————————————–
This alternating structure is repeated three times before moving onto the next
sections … to immitate the keyboards function guitar chords can be played
to follow the melody in some fashion – esp. in bars 7 and 8 of the [A] sections
(see below) …
(1b) slightly varied modal movement in the fifth mode of the Gb Melodic Minor
scale (half step up)
|| Db | EbDim/Db | Fdim/Db | EbDim/Db || x3
This movement uses the 5, 6 and 7 triads of Gb Melodic Minor over Db bass …
Db EbDim/C Fdim/C EbDim/C
—————————————————————————-
—–6——-7——-9——-7———————————————-
—–6——-8——10——-8———————————————-
—–6——-7——-9——-7———————————————-
—————————————————————————-
—–9——-9——-9——-9———————————————-
… on the second pass only two bars of this progression are played before going
to the next section
Db EbDim/C
—————————————————————————-
—–6——-7————————————————————–
—–6——-8————————————————————–
—–6——-7————————————————————–
—————————————————————————-
—–9——-9————————————————————–
(2) a modal movement in the fourth mode of A Major, ie. in D lydian
|| E/D | D | E/D | D | E/D | D || x1
E/D D
—————————————————————————-
——9——-7————————————————————–
——9——-7————————————————————–
——9——-7————————————————————–
—————————————————————————-
—–10——10————————————————————–
… on the fourth bar of this section the triads are inverted up following the
melody …
——————–s-12—-s-12—10–10–10–12–10——————–
—–7—10—12—-s-12—-s-12—10–10–10–12–10——————–

—–7—12—14———————————————————–
—————————————————————————-
—-(10)——————————————————————–
(3) a modal runaround in the fifth mode of C Major, ie. G7
|| E-/G | D-/G || x1
