House of Leaves
I've gotten tied up in reading House of Leaves by Mark Z. Danielewski. What an incredible work of literature! I'm about 3/4 of the way through and I'm thinking I'll have to re-read it immediately to get the full effect; there are so many mysteries.

Inter-Urban Industrial Update
The IUI has been downsized to something a little more manageable for my first foray into model railroading since I was a child. My little industrial empire now fits on a two foot by four foot table top. Here's the new plan:
I've left some expansion room to the right side, where the interchange track comes in. Where I intend to place the layout in my basement, I have another seven feet of shelf space about a foot wide. I've elevated the back side about 3/4" from the front to give a little interest to the terrain but the setting is essentially urban. The yard consists of 3 sorting tracks and a RIP track, with an engine terminal off the runaround. The right side of the loop also serves as the switching lead. The short siding crossing the yard lead serves a small freight station.
I've got the base built and a layer of foam on top of that. I've test fitted the track and will be ready to lay roadbed as soon as I purchase or manufacture the 3% grade inclines on get to the back industrial area.
Photos of progess to follow soon.

The Whole-Tone Scale and Augmented Chords
In my study of jazz improvisation pedagogy, I've noticed a relative scarcity of instruction related to the whole-tone scale and the augmented chord that derives from it. There is quite a bit of information on the lydian-augmented scale, which is the 3rd mode of the ascending melodic minor scale, but even here there is a lack instruction on how to apply the scale in context. It seems to me that most of the literature focusing on scales does not go far enough in explaining the application of such scales in the context of the entire structure of real songs. In other words, it's easy enough to see that particular notes of a scale (i.e. the intervalic distances from the tonic) correspond with a particular chord (especially its altered extensions) but what are the possible functions of a scale or chord related to the surrounding changes in a song?
The augmented scale has intrigued me since I first learned about it in junior high school. I was taking saxophone lessons from a guy that got me interested in jazz improvisation. I had learned to write and play all of the major and minor scales (both melodic and harmonic) from memory and I wondered what other scales existed that I might have to memorize, hoping there were none. That's when my instructor embarked on several lessons in scale and chord construction and the limitless possibilities of sound using only the 12 tones of our Western chromatic scale. The first thing he showed me was that scales could have fewer or more tones than 7 (the number of tones in the majors and minors) and proceded to write out the formula for constructing a whole-tone scale : 1-1-1-1-1-1 (he always wrote scale formulas in terms of the intervals between successive notes, so a major scale would be written 1-1-1/2- 1-1-1-1/2). When he asked me to play a whole-tone scale starting on C, I was blown away by how accustomed I had become to diatonicity. My fingers had a hard time finding F# and G#. The B-flat (as I thought of it, instead of A#) was not as foriegn because I was used to playing the mixolydian modes, with their flatted sevenths. What really intrigued me about the whole-tone scale was that there are really only two of them (and only 4 augmented chords).
I've been trying to figure out how to use the whole-tone scale and the augmented chord in my improvisation ever since my first revelation. One of the first things I discovered is that the augmented 5th naturally resolves upward to become the major 3rd of the next chord. So a C+ chord naturally moves to F major. In other words, an augmented chord functions like V7 leanding to I. This is useful for the end of a song that ends on the V because V+ will naturally lead to Imaj, and this is can be heard almost as a signature in many older R&B and do-wap songs. It's fun to put a V+7 at the end of a blues progression. The disonance of the whole-tone scale can be suspended for a greater length of time in this situation because the tension is usually the greatest here and the listener expects a resolution on the downbeat of the next chorus. A III-VI-II-V-I turnaround offers an opportunity for whole-tone utilization because the III, VI, and II are really just substitutes for the V and the whole sequence functions as single dominant leading to the tonic. Playing a line on the whole-tone scale I+ just before the change to IV can add a sense of playing "outside" or ""sideslipping" but this opportunity comes and goes quickly as the tension and resolution of a I-IV near the beginning of the chorus does not have the urgency of a V-I progression. I've been trying to think of a way to keep the dissonant energy of a whole-tone line going from the final V of a blues chorus, through the I at the start of a new chorus, all the way to the IV in the 5th bar but I've not been successful in pulling this off (yet).
I've had quite a bit of success playing whole-tone patterns in modal playing, especially "one-chord" tunes where playing outside is almost a requirement to break the monotony. In a recent extended solo on Chain of Fools (known euphemistically by our band as Chain of Chord, or sometimes just Chord), which is in C minor, I managed to build the tension up through the use of chromaticism and a neopolitan minor scale to 8 bars of whole tone figures on E-flat. This had the effect of adding a flatted 9th to an ascending C melodic minor while omitting the root. A few obtuse counter-figures from the rhythm section really polished off the effect.

Palindromes
You're about to get a glimpse of the way the Mind of Kevin Bowman works. This is also an example of why people who have ADD tendencies should stay away from the internet.
For reasons I can't remember, I was talking with a work mate about strange audio processesing algorithms when I recalled seeing a farcical processing device on the internet that named all of the controls and such with palindromes. A quick search found the device in question to be the palindrometer (found here). Then I remembered hearing a satirical skit on NPR (my buddy Dave calls it National Proletariat Radio) that was an interview with a guy named Bob, who spoke entirely in palindromes. Of couse, this instigated a thourough search of the 'net for a transcript of that dialog. I did not find what I was looking for but did find several sites dedicated to palindromes and one site led me to another on which I discovered an intersting (to me) mathematical problem involving numerical palindromes (numbers like 12321).
So now I'm completely intrigued by this mathematical problem, which you can read about here. I started thinking about a related subject: what does it mean to "reverse a number"? And I discovered a couple of interesting things:
1) The absolute value of the difference of a number and it's reverse is a number evenly divisible by nine. This was really no surprise once I remembered the old accounting trick related to transposed digits (if the error is a multiple of 9, you've probably made a transposition error).
2) The result of dividing the difference mentioned above by 9 is often a palindrome! This was true for all of the numbers I first experimented with. My first experiments were with sequencial digits, like 123, 456, 987654, etc. I even tried 196 (196 - 691 / 9 = 55). However, I was able to find numbers that, when subtracted from thier reverse and divided by 9, did not result in a palindrome (72157 - 75127 / 9 = 330).
3) At least for some numbers, the process of "reverse and subtract" (and taking the absolute value) results in a palindrome. The number 196 "solves" in this case:
196 - 691 = 495
495 - 594 = 99
Subtraction is nothing more than adding with negative numbers. Perhaps this will open the door to generalizing the "reverse and add" process and help gain some understanding with the 196 problem. Or perhaps I've just found another way to waste a bunch of time.

Model Railroad Theme
I've devised a name for my model railroad empire (such as it is). The theme is urban industrial and the name of the branch is the Inter-Urban Industrial Line. Pretty generic, I know. But since this is a freelanced layout (not representing any particular "real" place), I thought I could exercise a little artistic license. The Inter-Urban Industrial color scheme is orange, black, and white. The following two pictures are the logo on black field and on orange field, respectively:
When applied to locomotives, the horizontal stripes exend the length of the cab.
The era I am modeling is the early '60s. Steam has been completely phased out so the loco' fleet is entirely diesel or diesel-electric. A future expansion will model an interchange with a Grand Trunk double-track main, so some loco's from other railroads may operate on the IUI.
Here's the complete track plan: 
The 2' X 4' section in yellow is the future addition. The darker colored track near the top is hidden from view by buildings, backdrop, whatever. Structure placement and the layout of the downtown area on the right side is preliminary.
I still have to nail down the industries on the IUI. Some ideas include a pertroleum refinery, a couple of freight stations, a piano factory, a furniture factory, a brewery and/or bottling plant, a lumber yard, and distributers (in town) of fruit and bottled goods.

Miscellany
Today, I'm lamenting the fact that this blog has not been very interesting (totally boring is more like it). Creative juices have been flowing but not the kind that produce text of any sort.
I've spent quite a bit of time in the last six months thinking about and designing a modest model railroad layout. Construction will begin soon and I hope to have track laid and trains running before the New Year. My original plan occupied the entiure 19 feet of one wall in my finished basement. The final plan has been scaled back to 2' X 8' with accomodations for another 2' X 4' extention on an 'L'.
I've discovered a new addiction: Sudoku. It's a paper-and-pencil number placement game made popular by Nikoli publishing in Japan (though the game's roots are ancient). I obtained a book of 320 games, fairly evenly divided between easy, medium, hard, and extra hard puzzles. I can solve the easy puzzles in about 20 minutes. I've heard that expert solvers can complete a hard puzzle in about 10 minutes. I'll keep practicing.
