[BUG] Crossed fthora

[gugushvili]

In a line like Οἱ φοβούμενοι τὸν Κύριον, with a chromatic modulation followed by a return to the diatonic scale with a crossed fthora (permanent flat), automatic calculation of the martyria seems to break down.

Now this is a rare combination, but since the Musical Library editors have it, I guess it's an acceptable usage.

Is this really the best example? On the second syllable of "makarioi" it has a psifiston, which is a violation of orthographical rule 36. I looked this up in the Anastasimatarion by Peter Ephesios, and there it is written correctly without the psifiston and with an ajem on the Zo, which seems more correct to me:

I would be hesitant to make any changes to the software based on this example alone.

The first example has a psifiston on the second syllable of "makarioi", which is a violation of orthographical rule 36, so I do not think it is a good example. The modulation can be notated more clearly with an ajem, as in the image I posted above.

The second example seems like an ill-conceived modulation, not unusual in John's Anastasimatarion. In his New Anastasimatarion (1832) Chourmouzios writes a similar modulation with a diatonic Ke fthora before using the crossed fthora:

I'm simply not convinced that it's worth supporting these questionable examples (at the expense of making the software more complex) when there are clearly better ways of notating them.

Fokaeus does exactly the same as Ioannis:

Furthermore, here's an example from the Heirmologion of Chourmouzios, page 63. Chromatic fthora is lifted with the crossed one (...ὦ τάλας! ἐβόα ἐγώ· πρὸ γὰρ εἶδον σωματούμενον Θεόν... ):

Here is another example from Stephanos Lampadarios’ edition of the Anastasimatarion (Οἱ φοβούμενοι τὸν Κύριον).

Thank you Shota, these examples are much more clear to me, and I now agree that this ought to be supported. The example by Chourmouzios is absolutely convincing to me.

The crossed fthora is an odd creature. I have seen it used by Violakis on Ga (instead of the customary Ke) to indicate a permanently flattened Di. I don't know whether this has support in any early theory book.
