Re: Chord Names in Sagittal

Ok so just to clarify. P and p means Pao-major and Pai-minor, T and t mean Tai-major, and Tao-minor. Right? I thought I understood your intention there and was willing to go along with it and see how it panned out. But I thought you would use uppercase P for Pai because it is an upward alteration a...

Re: Chord Names in Sagittal

Hmm, so you're suggesting we use the pai7 as the default 7? Why not the tao7? Because the pai-flat 7 is the default in conventional music (where pai vanishes). The default 7th in 12-edo is not the tao-flat 7th (harmonic seventh). I would modify the above as: 1. No need to qualify the triad if it's ...

Re: Chord Names in Sagittal

Why not go the next step and drop the p and P and just call them Ct7 and C7? Because we don't do that in 12 EDO anyway, Cm7 means C Eb G Bb so Ct7 implies there is both a tai 3rd and tai 7th. Good point regarding Ct7. It would need to be written "C.t7" for it to be the approximate 4:5:6:7...

Re: 13-limit JI

On 2016-Sep-13, I wrote to Daniel Spreadbury (at Steinberg): Hi Daniel, I did post your explanation to the Sagittal forum. You can see a response here: http://forum.sagittal.org/viewtopic.php?p=372#p372 I just want to point out that since Dorico will only allow microtonality via EDOs, in order to no...

Re: Chord Names in Sagittal

Well in that case, I wouldn't even use major and minor, just the suffixes because it's too long winded to say all that. so 4:5:6:7 is C-pao-tai-7 or CPt7 for short possibly. C:E:\!::G:B:/|::b: can be called a C-pao-pai7 or CPp7 for short. Why not go the next step and drop the p and P and just call ...

Re: EDOs with multiple prime mappings

So, after spending some time on this, I have indeed discovered that by dividing 9/8 (the one consistent with the best 3/2, provided the best 3/2 is no sharper than 720¢) instead of the limma and apotome, I can accomplish exactly the same results as my original proposal with one fewer symbol pair, a...

Re: Chord Names in Sagittal

So I'm running into several qualms with sagittal chord names. Assuming we already know what to call accidentals, we have Pai, Pao, Pai-flat, pao-sharp. Here's my proposed system based on Cam's system with a few modifications for special chords. This post is mainly for 22 TET but applies to everythi...

Re: EDOs with multiple prime mappings

I've been working on this post for 2 days, so apologies if you've already covered some stuff in replies during the time I've been writing this. No worries. The 26edo notation has the advantage of treating 13edo as a spiral of whole-tones, whereas the 39edo version is a bit more complicated. I have ...

Re: 13 EDO

In the Xenharmonikon article we recommend notating it as every 3rd note of 39-edo. But Cryptic Ruse has just made a reasonable case for notating it as every second note of 26-edo. 26-edo: (A:B, C:D, D:E, F:G, G:A = 4) (B:C, E:F = 3) (# = 1) :26-edo A A:#: A:x: A:bb: A:b: A B:bb: B:b: B B:#: B:x: C:b...

Re: Key Signatures and MOS Notation

It would appear I forgot something. In trying to notate a score which is in A:\!: Major with some 5-comma shifts, I ended up using a key signature which has a B:\!: E:\!: A:\!: D:\!: so I'm finding that we need pai and pao key signatures for the other chain of fifths so our key signatures don't loo...
