As you posted an email intended to be private, a correction: I did not 
misremember, you really do use E60. :-)

It is Scala notation for the ETs: E72 = 72 ET, etc.

If this is the case, you should use preferably E53, but as it requires Graham 
Breed's file regular.y which currently is not in the LilyPond distribution, the 
next best thing would be E72, and as Persian music raises by to commas (E72 
tonesteps), it is in actuality in E36. So I would recommend using those. It 
would be nice to hear what somebody that knows this music well thinks about how 
these different tuning sound with Persian music.
