"Laudate" is the signature songbook piece of all AICSA choirs, and as such is the 'AICSA anthem'. If you are a member of an AICSA choir, such as PUCS, then you should probably learn this piece off by heart (you should also memorise several other pieces, including Come Again, Since First I Saw Your Face, and Pastime With Good Company, but Laudate should be your highest priority!) This is a simple piece of music, and is comparatively easy to memorise.
In particular, this piece is traditionally sung backstage after concerts by AICSA choirs, including PUCS.
Laudate has changed considerably since Christopher Tye published the original version in "The Actes of the Apostles" in 1553. Phillip Legge has written an excellent account of these changes, including a set of scores illustrating these changes (as well as a translation and proposed corrected version).
Here are midi (computer music) files for you to download and listen to (If you're using Microsoft Windows, simply click on the link and they should play automatically. If you're not using Windows, I'm going out on a limb and assuming you're technically competent enough to figure things out for yourself....).
Also note that there are midi files of each individual voice part for each piece, so you can hear what each one sounds like - especially your own!
These midi files should give you a fair idea of what each piece - and each individual voice part - sounds like, especially if you're unfamiliar with reading music.
And for those that would like to dowload a viewable and/or printable copy of the score (HINT: most people will want the PDF file; don't try to view the Postscript file unless you know what you're doing):
