Psalm Singing

After looking at Sharon's website I am like, wow. No exclamation point, just wow in a dull envious voice. I spent a few weeks looking all over the internet for Psalms in Hebrew. Everything I find is either paraphrased, or combined with other (uninspired) words, or too modern (I mean really modern, at high speed with pounding drums), or too short (one or two verses), or they repeat certain lines over and over, or else they are extremely complicated. Hardly anything suitable for congregational singing. Why don't the Jews sing their own Psalms? Beats me. It is a wonder that the Psalms can sit there in the Bible all these centuries and not be sung in their original language. For once I am thankful for my English-Irish-Scottish roots. I have all 150 Psalms, translated from the Hebrew, and edited no more than necessary to make them singable.
I have found a lot of really neat music, but what I am looking for is Psalms that an average singer in an average congregation can sing, without repeating lines, and hopefully without adding too many li-li-li's and na-na-na's. (Although I love li-li-li's and na-na-na's, and they sometimes make the tune come out right.)
I am trying to collect as many tunes as I can that have already been done. Most of what I find are short songs or chorus. Sometimes it's just one verse, or maybe two, with a refrain sung over and over. Not bad, but not enough.
I am trying to write tunes for Psalms but haven't had much success yet. I have about 9 tunes that I have started, but I'm not really satisfied 8 of them. I also can't really tell if they work, since I don't know the language very well. But I am still learning, both the language and how to write music, and I hope to get something that will work, and get the idea going, and then hopefully someone will come along that can do better.
The Psalms in Hebrew are very rhythmical, but they don't fit into an exact meter, such as C.M., L.M., or 10.10.10.10., or iambic pentameter, etc.
For an idea of how hard it is, try to write a tune for one of our (unmetricized) English Psalms.
The last two weeks I have spent studying the Psalms. The Hebrew of the Bible is quite different from modern Hebrew, and that of the Psalms especially. I got an attack of OCD which I hope has about run its course--I copied all the Psalms plus the first chapter of Genesis and made them into a list. I have been going through the list, sounding out the words and removing duplicates. Hebrew verbs are often written with prepositions attached to the beginning or pronouns attached to the end and such stuff, so it can be hard to tell if the first letter is a preposition or part of the word. I have so far narrowed it down from 15,000 to 4,000 words or groups of words. One group of words might include
"I heard, you will hear, hearing, to hear, they hear, hear me, hear him."
Or "house, the houses, my house, your houses, thy house, in the house, home-ward."
Now that I've spent an unreasonable amount of time on my list (but it was really helpful, since it solidified some of what I only half-learned in Ulpan), I hope to spend a reasonable amount of time finding the roots and learning the words. That will make it easier to write music.
