So )|) must also be 2deg70. My reason for choosing |~ for 2deg140 is that the flag is also used for 7deg (where this is no other choice), which serves to limit the total number of flags. However, this flag (taken as either a 19'-19 or a 23 flag) is not really a very good choice for either 1deg70 or 2deg140; the 17 flag ~| would be better for both. In 70-ET both 5 and 7 are awful, and whatever inconsistency we find for 17 is only with respect to 5 and 7. Taken separately, 17 is one of the best factors in 70-ET, and it's also better than either 19 or 23 in 140-ET. Using the 17 flag, I got the following easy-to-remember sequence of symbols: 140 (70 ss.): )| ~| /| )|) ~|) /|) (|~ (|\ )|| ~|| ||\ ) ||) ~||) /||\ The two disadvantages with this are that it uses 7 flags and has two pairs of laterally confusable symbols. So I would be more inclined to go with one of yours. Of the four options you gave, I agree with your choice of the last one (5 flags monotonic flags per symb), but with non-mirroring double- shaft symbols: 140 (70 ss.): )| |~ /| )|) /|~ /|) (|~ (|\ )|| ||~ ||\ ) ||) /||~ /||\ 5 flags monotonic flags per symb --George

Just different sense to what you have become used to over the past months. It is always an exact mirror image of the first half-apotome. The same pairs of symbols are _always_ complements of each other, in _every_ tuning. No exceptions. We should try to think like someone coming to sagittal notation for the first time. Or maybe we should actually ask a few people in that boat (e.g. Ted Mook). Would they rather have complements that were a complete no-brainer (just flip horizontally and add a stroke [except for !//| (natural) and /|\ ]), or would they rather have to learn the order of twice as many symbols for each new tuning. Clearly, under the current system the second half-apotome cannot easily be derived from the first, or we wouldn't be presenting various options and arguing over their merits.> All > to "fix" a problem involving not-quite-matched symbols /| and ||\ in > a few ET's? I say: "forget it."This is not the only reason for the mirror proposal. See the list of advantages I gave above for mirrored apotomes and read their converse as _disadvantages_ of the current system. It's just that, so long as I thought the half-apotomes were _always_ going to match (except for natural), and therefore folks only needed to learn the first half-apotome of any new tuning, then the mirror solution was, for me, hovering just below the the threshold of being considered. So far I have identified 4 solutions to be considered for the second apotome. 1. Always matched, except that !//| has various pseudo-matches [e.g. (|) or (|\ ] when /|\ is not an exact half-apotome. 2. Always mirrored, except !//| is always the pseudo-mirror of /||\, and /|\ is always the pseudo-mirror of (|) when /|\ is not an exact half-apotome. 3. Mostly matched. As for 1, except that /| and |\ are mirrored instead of matched when matching disagrees with an arithmetic that says that /| + ||\ = /| + ||\ = /||\ 4. Mostly mirrored. As for 2, except that mirroring is replaced by matching if the mirroring does not agree with an arithmetic where the second shaft represents the addition of an 11' comma. I thought we had agreed on 1, but it seems you actually had in mind 3, and presumably vice versa. Now, pending more argument from you (or anyone else), my order of preference is 1,2,4,3.

I'm finding the conversion aggravating, and I think temperaments should *always* be given in one of the two forms above. I'm sorry.

Message: 4986 - Contents - Hide Contents Date: Sun, 09 Jun 2002 21:21:27 Subject: gd update From: Carl Lumma I've added several scales (now there are 36), updated the Scala files, added a mean variety column to the spreadsheet. Excel 2000 Spreadsheet: * [with cont.] (Wayb.) Zip archive of the Scala files used: * [with cont.] (Wayb.) Explanation of the columns in the spreadsheet: * [with cont.] (Wayb.) Examples of the "diatonic harmony" metric: * [with cont.] (Wayb.) I've been trying to scan for scales that share a common rank-order matrix. The only ones I know of right now are rothenberg and balzano-20. That's right, Rothenberg, then Balzano, then Dan Stearns discovered this scale, all for different reasons. For R., it was a search of subsets of 31-tET with high stability and efficiency. For Balzano -- well, I won't go into it here. Stearns points out that there are 11:13:15, 1/(15:13:11) chords on scale degrees 1-3-5. It ranks high on my list because the 8ths are either 5:3 and 7:4. You'll get more out of the 31-tET version for those, but the 20-tET version gets you higher Lumma stability. As far as ranking the scales, the top ten according to the "diatonic harmony" property are: 08_octatonic 10_blackwood 06_hexatonic 07_diatonic 07_qm(2) 07_hungarian-minor 06_super7 05_pentatonic 10_sym-major 10_pent-major That's not bad, I'd say. The next two are: 09_balzano-20 / 09_rothenberg 08_nova This excludes Paul Hahn's trichordal scales and my subset-13 scale, having their high scores from the 12:7, which is arguably not singable in two-part harmony. For the next version, I hope to improve the modal transposition property (s - i isn't very good), find some method of creating a combined score out of the four, and robustly check for rank-order doubles. -Carl

Then I argue they would have little interest in temperament.I did say audible. Over on the main list, they are sniffing at the scale I gave in 612-et, but logically, should they?

This time the value in question is sqrt(18) = 4.242640686.

Even I am wondering how such a small comma can add many consonances in an 11-tone scale. Actually, if you really want to win friends and influence people, you'll have Maple draw a picture of the block in the lattice. Some of the naysayers might not even know what you mean by "increases consonances", that one can leave everything in JI and still ignore the wolf. -Carl

And the second biggest disadvantage is that not all of the single-shaft symbols have rational complements. However, I don't like the symbol arithmetic being completely different in the double-shaft symbols; it is counter- intuitive, especially in the fact that more flags make a smaller alteration, e.g., /||~ is a smaller alteration than either /|| or ||~, which occurs in your porposal for 111-ET. After carefully considering your mirroring proposal, I am making a counter-proposal for the determination of apotome complements that also eliminates both of these biggest disadvantages of the rational complements. This will look familiar, except that it has one added clause (to cover wavy flags): << For a symbol consisting of: 1) a left flag (or blank) 2) a single (or triple) stem, and 3) a right flag (or blank): 4) convert the single stem to a double (or triple to an X); 5) replace the left and right flags with their opposites according to the following: a) a straight flag is the opposite of a blank (and vice versa); b) a convex flag is the opposite of a concave flag (and vice versa); c) a wavy flag is its own opposite. This preserves most of the symbol arithmetic without encountering either of the two disadvantages you gave for mirrored complements. It also retains most of the advantages of your mirroring proposal.>> Advantages: >> >> Simple to remember -- check! >> Covers all tunings. -- check! >> Flags are more strongly associated with particular primes becausethe flags don't change when the comma is complemented; and>> No new flag types ever need to be introduced merely to handle complements.For straight flags used alone -- check!

(these completely retain their identities) For convex left flag used in combination with straight or convex right flag -- check! (these don't require double-shaft complements) This covers the situation for most of the lower-numbered ET's, which should keep the simple things simple. Convex flags are not used with concave or wavy flags (nor are concave flags generally used at all) until the notation starts getting more complicated, and I don't think that the complementation is going to result in too many new flags in those situations (we would have to try this to see).>> Doesn't require /| and ||\ as a special case. -- check!Plus there are the following additional advantages: Doesn't require /||\ to be an exception. Retains most of the symbol arithmetic used in single-shaft symbols. The exceptions are with the left convex and left concave flags. After looking at several ET's in which these are used, I believe that problems with these can be easily avoided in most cases, especially in the lower-numbered ET's. Let me know what you think about this (not-so-new) idea. --George

More flags being a smaller alteration, is a serious problem with mirrored complements.> After carefully considering your mirroring proposal, I am making a > counter-proposal for the determination of apotome complements that > also eliminates both of these biggest disadvantages of the rational > complements.

If you have time, could you repost your latest proposals, including any whose first half-apotome we've agreed on, using these complements? I've been working on what I call horizontal consistency in the first half-apotome. I believe it is more important than vertical consistency. Vertical consistency is between ETs where fifth-size is the same but number of steps per apotome in one is a multiple of the other, e.g. 48-ET and 96-ET. Horizontal consistency is between ETs that have the same number of steps per apotome, but have slightly different fifth sizes. ETs with same steps-per-apotome and adjacent fifth sizes, always differ by 7, e.g. 41-ET, 48-ET, 55-ET. Here are the proposals that have come from that investigation so far. I've added complements as per the above. To be notated as subsets of larger ETs: 2,3,4,5,6,7,8,9,10,11,13,14,15,16,18,20,21,23,25,28,30,33,35,40,47. 1 step per apotome 12,19,26: /||\ 2 steps per apotome 17,24,31,38: /|\ /||\ 45,52: /|) /||\ [13-comma] 3 steps per apotome 22,29: /| ||\ /||\ 36: |) ||) /||\ 43,50,57,64: /|) (|\ /||\ [13-commas] 4 steps per apotome 27: /| /|) ||\ /||\ [13-comma] 34,41,(48?): /| /|\ ||\ /||\ (48?),55: ~|) /|\ ~||( /||\ 62: |) /|\ (|\ /||\ [13-commas] 69,76: |) ??

What should I read in the Web and in the Lists to get a good understanding of the notation and terminology used in tuning-math? I understand what linear temperaments are but the notation used is not self-evident to me. I also have a basic understanding of periodicity blocks but hmm... wedges? commatic/chromatic unison vectors? Kalle
