This is taken from the topic:

but I figured we should include it here as well, since is growing to become THE source for all things Solresol-related :D

do = د

re = ر

mi = م

fa = ف

sol = س

la = ل

si = ت (actually a "t" sound, but the "s" sound has been taken for "sol")

And once again taking the sample sentence of "La misolredo mimiredo dore milasol falafado," we have:

ل مسرد ممرد در ملس فلفد

Remember that the Arabic script is written from right to left. ;)
