The trouble with this thread that the progressions cited above are not
all the *same* progression.
I can't speak to the Porter arrangement, but in the case of Meditation
and In The Still Of The Night (ITSOTN) we're looking at a movement to I.
In the case of SDMPWC we're looking a movement to IV.
Another problem with seeing the genesis of these progressions is the
fact that as jazz players we can actually influence a chord's harmonic
function somewhat by the colour tones we choose to use in our lines over
the chord.
So, for me, there are at least 3 ways I look at the Meditation progression:
1. A deceptive cadence of the secondary II-V progression, IIm7-V7-of-IIIm.
In C, F#m7-B7 is usually functioning as IIm7-V7/IIIm and resolves to
IIIm, i.e. Em.
In C, both Cmaj and Em possess tonic function.
They often serve as like-function substitutes for one another.
But with a IIm7-V7/IIIm progression, the chords comprising the IIm7/IIIm
and V7/IIIm are usually coloured with non-chord-tones from the E minor
scales (E nat min, E harm min, E mel min and/or E dorian (occasionally E
phrygian too, but it's rare).
In E minor, the norm on B7 is B7b9#9b13.
2. B7b9 is D#dim7/B.
D#dim7 is an inversion of Cdim7, the Idim7 chord in C major.
So when you play over the Meditation progression, if you choose to
colour the B7 chord as B7b9 your lines will be quite similar to ones
you'd come up with if you were thinking about playing on Cdim7 for that
same stretch of time.
So, if you're hearing it that way, the preceding F#m7 or F#m7b5 or
B7sus4 (which is what I usually play there) can be seen as a decoration
of B7b9 or of Cdim7/B.
3. But if you colour the B7 with non-chord-tones from the E major scale
(i.e. B mixolydian) the analysis of B7 as a voicing of Cdim7 doesn't
really hold up as well.
This is especially true if you emphasize the C# on the B7 chord.
If you're hearing it that way, IMO, it's really a temporary key change
into some version of the key of B with a mixolydian colour attached to
the tonic chord.
My own ear resists hearing it as #3, most of the time.
If I play, or play off of, some sort of an F#m chord in bar 2 of this
tune it will usually be F#m7b5 rather than F#m7 and on the B7 chord I'm
usually playing some form of b9 (C) #9 (D) and b13 (G).
For me, it's important to realize that all 3 of those notes exist within
both the E nat minor and C major scales.
The primary key of this tune is C major.
The secondary key at this point in time is E minor (even though the move
to an Em chord does not actually occur).
If I use the B altered dominant scale on B7, which is the 7th
mode/rotation of C melodic minor), then it's kind of like it's a move
from C major to C minor and back to C major.
I guess this is a 4th way to analyze this chord.
The B altered dominant scale introduces another colour tone, #11 (F),
and dispenses with one of the original chord tones of B7, the F#.
The note F is an important member of the C major scale but it is not in
any of the standard E minor scales (except E phrygian) so it may sound
somewhat out of place here if used insensitively even though it is a
strong note vertically-speaking.
Using the B half-whole diminished scale on B7 helps to reinforce the
feeling of B7b9 being related to Cdim7.
B half-whole = C whole-half.
The colour tones involved here then, would be b9 (C) #9 (D) #11 (F) and
13 (G#).
I've already discussed the C D and F.
The G# is interesting to me because it is not found in the scales of
either the primary key (C major) or the secondary key (E minor).
As such, it can sound a little bit out of place here is used insensitively.
But the G# fits the chord vertically and sounds strong,
harmonically-speaking, when emphasized on this chord.
By choosing this scale colour on this chord you step into the realm of
the vertically-oriented player and leave the more key-oriented
horizontal approach behind to some degree.
The same could be said about the player who decides to use and B
mixolydian in that by colouring this chord with tones that lie outside
of the prevailing keys (C major and E minor), the integrity of your
lines will be based more upon vertical relationships within the
chord-of-the-moment rather than on the relationships within the key of
the moment.
IMO.
This happens a lot with jazz players, ofgten intuitively but sometimes
more consciously too, that by choosing to colour a chord with notes that
fit the chord vertically rather than notes that help to reinforce the
key feeling, the original justification/meaning/analysis of the way that
chord functions within the original written progression can be influenced.
Sometimes we take chords that are merely decorations of a more essential
chord and decide to play off of the decoration as if it too is an
essential chord.
The effect is that of raising the stature of the decoration which
actually creates a different progression than the originally written
progression.
It's all part of being an improviser.
So, if the original function of B7 here is really as a voicing of Idim7,
by treating/writing it as an actual B7 chord, especially when emphasis
of C# (9) occurs, it can be seen as involving various ways to vertically
colour *this* chord as opposed to Idim7.
I.e. Cdim7 becomes B7 which then becomes something else that can itself
be decorated.
The progression in SDMPWC is different.
In Bb major, a D7 chord is usually moving to Gm as V7/VIm.
But this D7 chord moves to Ebmaj7 instead of Gm.
In this key, Ebmaj7 (IVmaj7) can not be seen as a like-function
substitute for Gm (VIm).
In Bb major, Gm chords also have tonic function.
But any chord containing scale-degree 4 of the key (in Bb major, S4 =
Eb) can not possess tonic function.
In major keys, S4 is the destroyer of T function.
So although our Ebmaj7 chord contains all the tones of a Gm triad within
it, it is not a T function chord in either Bb major or G minor (G minor
would be our secondary key here if we ever actually got to a Gm chord,
which we don't).
So, we *can* look at D7 to Ebmaj7 as being a deceptive cadence of
V7/VIm, but it's not the same type of deceptive cadence as it would be
if we were in the key of Eb major because in Eb major, both Ebmaj7 and
Gm7 *do* have T function.
Another view of this progression involves the common tones between D7#5
and Bb9#5.
I.e. The D7#5 here can be heard as a partial voicing of Bb9#5 which
would be functioning as V7/IV if Bb7 were the actual change here.
So again, as improvisers we can actually influence the harmonic function
of a chord to be somewhat different than its original function within
the written progression by the colour tones we choose to play on top of it.
I.e. If you play over this D7 with notes you'd usually use over Bb7#5
*you* actually turn it into Bb7#5.
Now, as soon as you emphasize an A natural over the D7 chord, the
analysis of it being a voicing of V7/IV breaks down.
But you can still look at it as a voicing of Bbmaj7#5/D, which can also
serve as an approach chord to Ebmaj7.
The important guide-tone line here is F (on the Bb chord) moving to F#
(on the D7 chord) moving to G on the Eb chord.
Imagine that there was no D7 chord on the chart in bar 2.
You could then see this as 2 bars of Bbma7 (T) moving to Eb (SD) in bar 3.
We can then see that the F# is just a chromatic passing that helps to
join Bbmaj7 to Ebmaj7.
If you hear/see it that way then this is one of those cases where an
non-essential vertical sonority that comes about merely as an artifact
of decoration is promoted to the more important status of a
chord-in-its-own-rite.
Here's my analysis of the opening chords of Meditation:
C:
T D (in E minor) T
I V7sus4/IIIm V7/IIIm I (Deceptive Cadence)
Cmaj13 / / / | / / / / |B7sus4 / / / |B7 / / / |Cmaj13 etc.....
Here's my analysis of the opening chords of SDMPWC:
Bb:
T (D inIn G minor) SD (D in C minor) SD
I V7/VIm IV V7/IIm IIm
Bbmaj7 / / / |D7#5 / / / |Ebmaj7 / / / |G7 / / / |Cm etc....
So, the actual Roman numeral functional analysis doesn't really explain
all that much about the progression or how to play over these chords.
A player has to spend a lot of time ruminating about all of the various
interrelationships here to find his own path, note-choice-wise, through
these progressions because there is no single "right" way to hear them
or to play over them.
They all have a high level of ambiguity built into them.
