Another Angle for this LCS topic
Posted: Fri Nov 13, 2009 2:33 pm
Russell's argumentation about the Lydian Scale draws a lot from ancient Chinese (and other Asian) sources and theories. They were big on cycles of fifths and even found ways/systems to turn the spiral of fifths into a closed circle for purposes of modulation. Although they primarily used pentatonic scales rather than full-out Lydian scales, the point is their recognition of the fifth's importance.
However, an important but less-known source of insight into ancient Chinese theory/practice is a bell-set that was unearthed in 1977 or 1978.

The main insight given is that the bell-set's tuning (much like ET) compromises the fifths a little in order to achieve better thirds. This suggests, for one thing, that more than just monophonic music was practiced back then, and secondly, that although ladders/cycles of fifths were an important aspect of their theories, the limitations of only fifths were recognized.
Ironically, although this tuning system aligns with the 'parallel-OSI' theory/model that I have described earlier, it also could be seen to offer an alternate explanation for Russell's Lydian Chromatic Order.
The basic idea is, rather than a ladder of only fifths (third partial of OS), the system starts with a row of four tones spaced a fifth apart (although a somewhat tempered fifth):
C G D A
Then, rather than the next tone, E, being another fifth above A, resulting in a disagreeable major third, the E is tuned relative to the C (tuning to the 5th partial of C). In fact, ALL of the remaining tones in the 12-tone system are tuned to the 5th partial (major third) relative to the original four tones a fifth apart:
E...B...F#..C#
C...G...D...A
Ab..Eb.Bb..F
Although never intended to be a theory for 'larger-than-lydian' verticalities (it's unlikely their harmony exceeded triads), one could certainly find support for the order of the LCS from this tuning system and it's governing theory.
If all three tones related to the lowermost tone in the series of fifths (C) were sounded together with the four-tone ladder itself, you would have C D E G Ab A - similar to Lydian Augmented. If you derived your scale similarly from the four-tone ladder and both tones related to the second tone by thirds, you'd have C D Eb G A B - similar to Lydian Diminished. Similarly, deriving a scale from the mini-ladder plus the third tone's M3 relatives would give you C D F# G A Bb - similar to Lydian Flat Seventh. The "outgoingness" of each scale has to do with how far up the ladder the additional tones (tuned in thirds) are anchored in to the fifth-based structure. Logically, the m2 and P4 are anchored to the highest, or most 'outgoing' member of the four-tone ladder.
I don't know, maybe this is nuts, but the LCO seems to be in close agreement to this ancient tuning system, despite the fact that it was only designed (as far as we know) to produce natural triads within an otherwise 'circle-of-fifths' modulation model.
Despite all of my ongoing argumentation against the Lydian Chromatic Order, there seems to be indirect impirical support for it from certain angles.
My irritation with the LCS has always stemmed from it's seeming contradiction to the ladder-of-fifths model. I have explored first that it may be the ladder model that was wrong, then from the perspective that the ladder was right and the LCS wrong. I can't help but feel that they disagree with one another, but maybe this ancient tuning system suggests that the ladder itself is what must be compromised in order to vindicate the LCS/order after all.
