Dan,

 

The harp only plays in the 5th, 7th, and 9th movements. In the 5th, it doubles the organ throughout. The harp part is essential in the 7th movement, incidental in the 9th.

 

My edition, published by Colla Voce Music, has the original orchestration, as well as an adaptation for piano, organ, and optional harp. Information at:

I have done it with organ, strings, and piano filling in for the missing harp. Contact me for details on that, or for the materials.

 

My edition is one of the few recent ones that doesn't cost an arm and a leg. The notation is clean and modern; it includes the original Latin along with a new English translation which avoids many of the problems found in other scores. It is available directly from Colla Voce, from J.W. Pepper, or any other music retailer.

My church owns the Schirmer edition, which I bought second-hand a few years back. It is also the edition found at IMSLP.org. The parts are also available there. I reccomend buying the vocal scores but down;oading the parts.

Dan,

 

I have used Lee's edition several times and can vouch for its excellence. The only edition I would recommend over his would be an original french edition. There are several errors in the Schirmer edition that I have found.

Mr. Barrow's advise is excellent.  The work can be done with piano, but the harp is really a stunning addition.  I've done it with just organ and harp with great success.  Adding the strings to that is even better.

 

My biggest concern in this work is making sure to have five superb soloists.  The solo and ensemble movements ... solo, duet, trio, quartet and quintet ... in order ... each require experienced singers who are very able and who have sung in small ensembles like this before.  Don't skimp on that part of your budget. The choral parts are easy, but the solos are just the opposite ... quite a challenge.  Best of luck with a great work!
