For the time being I'm hard coding modes into my composition program. What I've got so far are shown in the image. If anyone has any sugestions for useful modes that can be defined within the 12 chromatic tones of standard notation please give me the name and half-step pattern and I'll add them while it's still easy.

There are a few duplicates of common patterns but the name symbols will provide differentiation in certain contexts.

Well, my NYE 2009-2010 performance made use of dorian, locrian, and phrygian, which you've got covered, and minor pentatonic, which seems to be missing.

Here's one of my favorites, which I thought I might have invented at the time, although apparently there is a scale used in India that maps to this in equally tempered scale. These are number of half steps from the tonic, starting at 0 for the tonic.

0 2 3 6 7 10 11 (12)

I envision this as an arched bridged with the two big spans (3 half steps each) anchored on an island in the middle of a river. I pick a kick-ass, middle-eastern flavored tune on the banjo with this. Got a name for it?

I used this minor blues scale in my NYE piece:

0 3 5 6 7 10 (12)

That one I got out of a book.

In Scrabble-to-MIDI I also have "scales" in my config file that are simply triads (major and minor), interval pairs, and just a root note repeated at a few octaves. A single note scale! I'll switch a scrabble-to-midi channel to use that "scale" to get drones, for example, when translating a word list to notes.

Typically some section of a scrabble-to-midi piece will use overlapping but non-identical scales on different channels, e.g., minor blues, dorian, locrian, phrygian and minor pentatonic all at once, so they breathe together on the frequently occurring letters and apart on the outlying letters. I usually resolve back to a colelction of non-conflicting scales after that.

Be careful what you ask for!

I have it as "Parson Minor" until I can find its real name again. Thanks.

Here is the closest that I can find in a quick search
Quote:

3.4.4. Cycle X (C.D.: C D Eb F# G)

The Bb abd B are missing. There is an exact match, presumably a variant of this cycle.

From my new scale book:

Code:
Harmonic Minor:                     2,1,2,2,1,3,1
Melodic Minor:                      2,1,2,2,2,2,1
Jazz Melodic Minor:                 2,1,2,2,2,2,1
Dorian b2:                          1,2,2,2,2,1,2
Lydian Augmented:                   2,2,2,2,1,2,1
Lydian b7 (overtone):               2,2,2,1,2,1,2
Mixolydian b13 (Hindu):             2,2,1,2,1,2,2
Locrian #2:                         2,1,2,1,2,2,2
Super Locrian (altered):            1,2,1,2,2,2,2
Blues:                              3,2,1,1,3,2
Minor Blues:                        2,1,2,1,1,1,2,2
Major blues:                        2,1,1,1,1,1,2,1,2
                                   
Exotic scales:                     
                                   
Enigmatic:                          1,3,2,2,2,1,1
Double Harmonic (Gyspy, Byzantine): 1,3,1,2,1,3,1
Hungarian Minor:                    2,1,3,1,1,3,1
Persian:                            1,3,1,1,2,3,1
Arabian (Major Locrian:)            2,2,1,1,2,2,2
Japanese:                           1,4,2,1,4
Egyptian:                           2,3,2,3,2
Hirajoshi:                          2,1,4,1,4


The usual blues scales are pentatonic with an added flattened fifth (or so I'm lead to believe), so I'm not sure why the book lists the maj & min blues scales as above - I include them for completeness...

Could you read the modes from a text file? Then it would never be too late to add some Smile

This source shows Parson Minor as Saranga. That's not the name I remember.

I do now recall that it was close to Hungarian Minor, but no cigar!

In Googling "saranga" and browsing the "raga sarang" entries, it appears that Saranga may be incorrect. Blinkety-blank Internet.

Thanks for the scales -- but I guess the question is which do you find important.

Yea, extensibility for mode definitions is on the list of future enhancements. But at this point I'm trying to keep tasks from proliferating with out end. I've just finished the algorithm for assigning accidentals to the standard diatonic modes which was fairly straight forward. An algorithm to intelligently assign accidentals to arbitrarily constructed modes appears, on the surface, to be more problematic. Any thoughts on that problem would be most welcome.

Thanks dale. No probelm to change the name later (in the code). Don't knock yourself out over it Smile
