Re: Paul Rapoport

Paul. In the paper, you limited your investigations to notating EDOs using symbols representing 5-limit commas, and 1/n of those commas, but you encouraged investigation of higher harmonics. I understand you later investigated these yourself, as well as notations for JI. I'd be interested to know wh...

Paul Rapoport

Paul Rapoport's 24-page paper The Notation of Equal Temperaments was written in 1991 and published in 1995 in Xenharmonikôn 16. It was a major influence in the design of Sagittal — not so much for its symbols, but for its systematic approach to the meaning behind the symbols. This was aimed at expos...

Re: New Olympian diacritics

Magrathean Diacritics I received the following query by email: ... I noticed SMuFL had a range for Magrathean Sagittal. Just wondering about the current state of the project, and what it would be like. I had difficulty finding what George and I had agreed on, about 5 years ago. So I thought I shoul...

Re: Timeout while preparing a reply

Grrr, this just happened to me. I was logged in via YouTube. Why not set it to -1 and see if the issue goes away? Jacob. I'm so sorry. I have done as you suggest, setting it to -1. Also, I got a message from facebook telling me to update some settings related to the Sagittal forum. These were proba...

Re: A proposal to simplify the notation of EDOs with bad fifths

I suggest that, to reduce the total number of symbols required to cover all the EDOs up to 72, we adopt the alternative notation for 58-edo described in the note at the bottom of page 15 of the XH article. i.e.

Change it from
58: :/|: :(|(: :/|\:
to
58: :/|: :|\: :/|\:

Compose-key definitions for easy typing of Sagittals

There is a wonderful keyboard mapping utility for Microsoft Windows called WinCompose, written by Sam Hocevar. Similar Compose-key products are available for Linux and MacOS. When used with the Bravura font and the definitions below, it will allow you to type Sagittal characters as easily-remembered...

Re: A proposal to simplify the notation of EDOs with bad fifths

66 is 1:3:17 consistent. It is not 1:3:p consistent for any other prime p up to 19 (no higher primes were checked). So no useful JI-based notation is possible for it. But the following apotome-fraction notation is acceptable. Although :)~|: is not valid as 2 degrees, it's close. 66: :)|: :)~|: :/|:...

Re: A proposal to simplify the notation of EDOs with bad fifths

Thanks George. I really appreciating you working on tidying those loose ends. Particularly the following, that affects so many divisions. Yes, I agree that where 13M is used as 1/2 apotome it can be replaced with 13L. However, in each instance we need to check that :/|): is actually valid as 13M (an...

Re: A proposal to simplify the notation of EDOs with bad fifths

I concluded that a native notation [for 44] is much better (and simpler) than a subset notation, so we should omit any mention of a subset notation, since the fifths are not really bad. We came up with slightly different native notations: 44: :)~|: :/|: :(|\: :||\: :~||\: :/||\: (DK 7/20/18; 1:3:5:...
