### Re: List of 7-prime limit / 6125-odd limit accidentals

I think your asterisk note above should say "* ambiguous, usually refers to a different comma" rather than "... different accidental". The ratios are a mixed collection from personal experience, my own comma lists, commas from popular temperaments, or commas / ratios from the fol...

### Re: List of 7-prime limit / 6125-odd limit accidentals

One accidental pair which I'd be interested in is for 256:245, the difference between 8/7 and 35/32. 245:256 is :.::~~||: which is the apotome-complement of :'::~|): i.e. :.::~~||: = :.::~!)::#: 9:10 is :.::)X(: = :.::\ \!::x: You should be able to get the rest from George's spreadsheet, using figu...

### Re: List of 7-prime limit / 6125-odd limit accidentals

That's marvelous work, Xen. For Moments of Symmetry based on pentatonic scales, it would be very useful to have accidentals for 16:15 and 256:243. 15:16 is :.::/||\: 256:243, the limma, is :.::||\: I think I'd prefer to use two accidentals for neutral or major second-sized ratios like 160/147 or 9/8...

### Re: EDOs with multiple prime mappings

I must admit this comes as rather a shock, after having come around to your way of thinking regarding the use of fractional 3-limit notations, at least in the case of EDOs with medium to large errors in their fifths. Alright, I've banged my head against the wall long enough. What was the metaphorica...

### 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...
