Hello Craig,
First of all, thank you for replying.
In my question concerning the half-flat, I meant the Arabic half-flat (Arabic quarter-tone flat) that has the same symbol as the one shown in the picture above.
The one that you sent to me is the Turkish half-flat that has a different symbol than this one. Does this (Arabic half-flat) exist now in MEI accidental and can we include it in the key signature? Can verovio also support the rendering of the half-flat described above?
Thank you in advance,
Charbel El Achkar

Hello Charbel,
Yes, half-flats are possible in MEI and verovio. Here is the MEI list of accidentals:
http://music-encoding.org/guidelines/v3/data-types/data.accidental.explicit.html
data.ACCIDENTAL.EXPLICIT<http://music-encoding.org/guidelines/v3/data-types/data.accidental.explicit.html>

("1qf" is the name of the "one quarter-tone flat" in MEI data)
> if yes can we also encode this half-flat at the beginning of the musical piece (armature) in order to apply it to a specified string in the musical measure?
Do you mean include half-flats in the key signature, or another graphical system for the instrument tuning? The first should be possible in MEI, although I do not know if it is implemented in verovio, the second is unlikely implemented in verovio, and probably not in MEI.
Here is an example with half-flats. The rendering in verovio:

To whom it may concern,
I would like to ask if the Half flat (Arabic quarter-tone flat) is available now in MEI in order to encode it as MEI accidental and if verovio supports the rendering of this feature?
please provide an example (.svg) . if yes can we also encode this half-flat at the beginning of the musical piece (armature) in order to apply it to a specified string in the musical measure?
Thank you for your cooperation,
