Yes, that's it. You can see it in Maqam Bayatti for example, and I can now plot it for the occasional accidental using the function Valentin gave me in his reply. Here's another link that shows some of the more common maqams that are used in Arabic music. http://www.turath.org/ProfilesMenu.htm I haven't noticed the up/down usage in maqamworld, but probably I just missed it. I've seen other notations such as the use of series of + and - used against notes to alter the pitch. The use of the flat, sharp, half flat and half sharp, three quarter sharp (I don't see the three quarter flat being used much in arabic pieces) is fairly standard in Arabic music notation, and the same as the LilyPond display except for the half-flat.

The arabic word is "qarar" which means literally a decision but in the music context it means roughly the resting or the settling point, and there is no implication of harmony.

Here it is : I have been trying to work out the rules on this for the last few days, but I don't think there are any that are set in stone, so I've been going through example pieces and theory books that I have and looking for patterns. There are some inconsistencies even within the same book, but there are also some patterns. I guess in the end, it doesn't matter much how accidentals are marked if the composer or even the editor wishes to change it, but here's what I found so far. A key signature reflects a group or family of modes, so the family of Bayatti modes that have the same default finalis (re or e) would all have the same key signature of mi half-flat and si flat (e half-flat and b flat). So , if we take for example a Husseini maqam which is close enough to Bayatti to be considered as a member of the same group, it would usualy written with the key signature of Bayatti, and the accidentals where it differs from Bayatti are written in the body of the piece. Even Saba that is sometimes considered in a different group from Bayatti is still considered similar enough to have the same signature of Bayatti, and the fourth note (sol) that is almost always flat is written as a flat throughout the piece rather than in the key signature. This is in some way good news, because it means that I only need to define few additional key signatures for Arabic music, but can lead to somewhat strange results, where sometimes a note in the key signature is actually never played that way, and another that is always an accidental is not in the key signature. It seems that in the books I have seen at least, the key signature is used to indicate the group or family. If we then take a family key signature such as Bayatti, and want another finalis such as sol rather than re, then the key signature would be modulated, so it will be la half-flat, si flat, mi flat (a half-flat, b flat, e flat), and husseini on sol if there is such a thing, or saba on sol would have the same key signature. Even though the key signature indicates the group or the more maqam in the group, rather than necessarily the particular maqam, the particular mode or maqam is often indicated in the title of the piece, as well as the form, so one piece for example would have a title of "Longa Saba" and a key signature of bayatti. Here Longa indicates the form, and Saba the maqam. I think that most of these pieces that I'm looking at in Oud instruction books, have a Turkish origin, given the names of the forms and the authors. It is not usual in Arabic culture, to adopt forms from other cultures, and then change them drastically, so I would just guess, but I'm not sure, that the practices in writing Arabic music, the names of maqams, and so on, are not very different from what is used in Turkish music, although there is usually no attempt in Arabic music, as I mentioned previously, to indicate microtones precisely.
