If you don't know about it already, you should definately check out the forum at musicasacra.com.  Jeffrey and Arlene have set up an active community of sacred musicians discussing topics from the pragmatic to the theoretical and historical and beyond.  You can ask your questions about reading and singing Gregorian chant (and usually get an answer), or join in a conversation about how we got where we are today and what to do about it now.  No longer do you need to feel alone fighting the good fight to restore the sacred to music in the Catholic Church.

You will also realize the wide diversity of viewpoints people bring to this side of the renewal of sacred music.  And I find from time to time I come across people who do not think that the Holy Spirit blew into the Church with Vatican II.   It's all right, because this is a venue of dialogue.  I appreciate that.  I don't think anything I will say will ever change anyone's mind, but it's very encouraging to find that there is plenty of common ground where sacred musicians can meet and move forward with an authentic renewal of sacred music. 

So, be sure to check out the sacred music forum.
