Hello
/hel-arabic.ly use a notation I created myself: /
/bb the second b means flat /
/bd  d: means sharp #/
/adb: db means half flat (1/2 flat)/
/add: dd means half sharp (1/2 #)/

/ 7/2 tone is not used (3/4 tone can be used )/
/I hope I was clear/

/Arabic music in fact uses practically only the tone,//semitone and quarter tone /

Thanks, however my question about 7/2 tones is not answered: if a 7/2 tone alteration is not used, why do the "arabic" language and hel-arabic.ly have not names and alterations for 7/2 alterations? To wit: Is it a workaround for the fact that LilyPond does not have a way to define note names for the same pitch with different accidentals?
