Peter the Aleut and Handmaiden of God,
Thank you both

Actually my choir director has been extraordinarily helpful in just helping me
sing ... and transition from western to eastern music in general. And patient, as have been all of the choir members. Everyone reassures me they grew up with this music and so "osmosed" it ... but to come at it new just takes time. The most helpful, or reassuring, said "a couple of years."
I'll try the OCA link here right away. That's the kind of thing I'm looking for!
grace & peace,
jeremiah
